Classic white cake, swirled with colored batter for a patriotic flair. Change up the colors to match your occasion!
Can you even believe it’s time for red, white, and blue treats already? The 4th of July is right around the corner, so naturally, we’re turning regular treats into patriotic ones, because then they taste better, right??
I remember this time in 2016 and 2018 vividly. Both summers, we had a few-weeks-old screamy baby, and most particularly with that first baby, I was so glad to have an hour to myself in the early hours of the morning where I turned regular Rice Krispies Treats into a fruity berry version to share in time for the holiday season.
These days, throwing this patriotic treat together involves much less screaming, but I forever have sous chefs asking to help with all the things, which results in bigger messes than necessary and cleaning up stray sprinkles as quickly as possible.
If you’ve been around these parts for awhile, you’ll know that in 2017, I did a Cake of The Month feature every month, and this one was installment #6! That meant halfway to Christmas and this fine celebration, but hey, let’s not get ahead of ourselves. We still have hotdogs to eat, fireworks to light, and grilling to do!
The nice part about this red, white, and blue swirled bundt cake is we’ve been here before. It’s actually my white layer cake recipe, but in a bundt pan. And obviously with some red and blue business going on.
I won’t talk too much about how this recipe came to be since you can read all about it in this white layer cake post, but instead, we will focus on exactly how you get your batter colored the right color and swirled in your finished cake so perfectly.
HOW TO GET COLORFUL SWIRLS IN CAKE BATTER
To get beautifully colored swirls in your cake, you’re going to start the cake batter like you normally would. You’ll stop right at the point of putting the batter into the pans to bake, but you’ll remove some batter to dye red and blue.
Pour out about half of the batter to dye, putting half of that into one bowl and the other half in another bowl, so you’ll have about ¼ of the batter in each bowl, ready to become colorful.
Make sense? Half stays white, half gets colored.
If you want to make this cake different colors for another occasion (say, Halloween, with green, purple, and orange), same idea: half stays white, half gets colored. The other half will just split into 3 bowls.
You following?
You can certainly use liquid food coloring, but I have always preferred gel colors. My favorite are Americolor. I prefer gel because the colors are more concentrated and vibrant, and the batter doesn’t get watered down by lots of liquid drops.
Once you have your red and blue batters, get to the creativity!
I always start my swirled cakes by putting a few dollops of colored batter in the bottom of the bundt pan. Just a few. Next up, a light layer of white. The key here is to be gentle and try not to disturb the colored dollops. In recipes where the idea is to swirl (like peanut butter ripple ice cream), mixing of colors/batters is encouraged.
Here? No.
With two colors of batter, you run the risk of getting purple swirls, which would be pretty, but not what we want here. Because of the nature of how batter bakes, the dollops almost swirl themselves.
Neat, huh?
I suggest making about 3 layers of color and white batter, not worrying much about dollops peeking through or not getting covered completely.
I do, however, try to avoid putting a big dollop of red batter on top of another red dollop. Big dollops, small dollops– whatever! Get creative.
After your bundt cake is fully baked, you’ll want to flip it out of the pan as soon as you can. Let it cool for about 10 minutes, put a plate or your serving platter on top of the pan, then flip while using oven mitts.
You’ll let the cake cool completely upside down (right side up?!) on the platter. This will prevent the top of the bundt sticking to the pan and destroying the pretty grooves. Of course, if you’re covering it with frosting like I did, that doesn’t really matter much, but it’s good practice for bundt cake baking.
I went with a half recipe of my classic buttercream, which was the perfect amount, but you’re welcome to use whatever frosting you’d like and make it a full recipe if you’d like, keeping in mind that you’ll be able to cover the cake much more thoroughly than I did.
Leave your red, white, and blue bundt cake plain, dust it with powdered sugar, get fancy and use a lemon buttercream, a whipped cream buttercream, plain ole whipped cream, or an orange cream cheese buttercream. The only thing that is basically required is a hefty dose of patriotic sprinkles!
I’ll tell you what, folks… My taste testers are always blown away by this, which is funny, considering it’s just my white cake with swirly colors. I first took it to my company summer picnic and I took nothing home but stray sprinkles on a plate, and the reviews that have come in from readers in the past have been nothing but positive, too.
Something about the texture of this bundt cake does, admittedly, always bring me back for more. I added an extra teaspoon of baking powder to the original recipe (thanks for the tip, Bundt Cake Queen!) to account for the taller nature of the bundt pan, but perhaps that little bit of lift was enough to take this amazing cake to an even higher level of amazing?? Who knows?
Either way, this easy yet impressive cake is a must this 4th of July. MUST!!
Here’s to America, despite the weird year it’s been for all of us, I think we can all agree on one thing– ALWAYS YES TO CAKE.
Red, White, & Blue Swirl Bundt Cake
Ingredients
CAKE
- 2 cups (240g) all-purpose flour be sure to measure properly
- 2 Tablespoons (15g) cornstarch
- 1 and ¾ cups (350g) granulated sugar
- 5 teaspoons baking powder
- 1 teaspoon salt
- 12 Tablespoons (170g) unsalted butter softened to room temperature1
- 1 cup (240mL) heavy cream room temperature1,3
- 6 large egg whites room temperature1
- 2 and ½ teaspoons vanilla extract
- red food coloring2
- blue food coloring2
VANILLA BUTTERCREAM
- ½ cup (113g) unsalted butter softened to room temperature
- 2 cups (240g) powdered sugar
- ½ teaspoon vanilla extract
- 2 Tablespoons (30mL) milk or cream
- salt to taste
Instructions
CAKE
- Place oven rack on the middle setting and preheat the oven to 350ºF (177ºC). Generously grease and flour (or use homemade cake release) a 10" bundt pan.
- In a large bowl with a handheld mixer or the bowl of a stand mixer fitted with the paddle attachment, combine the flour, cornstarch, sugar, baking powder, and salt. Blend ingredients together on low until completely combined, about 1 minute. Add the room temperature butter and beat mixture on low speed until it resembles sand. Scrape down the sides and bottom of the bowl with a spatula and mix again on low for a few seconds until thoroughly combined.
- Combine the heavy cream, egg whites, and vanilla extract in a large container with a spout (like a 2-cup glass measuring cup) and mix gently with a fork until blended. With the mixer speed on medium-low, add half of the milk mixture (about 1 cup) to the crumb mixture and mix until blended. Add the remaining milk mixture to the batter and beat again on medium-low until everything is incorporated. Turn the mixer off, scrape down the sides and bottom of the bowl with a spatula, and increase mixer speed to medium. Beat the batter for about 30 seconds until batter is smooth.
- Pour about ¼ of the batter into one small bowl, and another ¼ of the batter into another small bowl (these are the portions you will color). You should be left without about half of the batter in your mixing bowl. Set that aside.
- Add a bit of red food coloring to one of the small bowls, stir, and add more coloring until it is to your liking. Repeat with the second bowl and the blue coloring. Using a spoon or spatula, add a few dollops of each color batter to the bottom of the bundt pan. Pour about ⅓of the white batter over the dollops. Repeat again until you run out of batter. Tap the bundt pan gently on the counter to allow layers to settle, then bake for 38-40 minutes, or until a toothpick inserted in the center comes out clean.
- Remove from oven and allow to cool for 10 minutes on a wire cooling rack. Using oven mitts, carefully flip the bundt cake onto your serving dish/platter. To do this: flip the serving dish/platter over and place on top of the cooling bundt pan. Flip everything over and allow cake to cool completely in the pan, sitting on the serving dish. When cake is completely cool, lift pan off of the cake.
VANILLA BUTTERCREAM
- In a large bowl with a handheld mixer, or a stand mixer fitted with the paddle attachment, beat the butter on medium speed until creamy, about 2 minutes.
- With the mixer on low, add in the powdered sugar, vanilla, and milk or cream. Increase mixer speed to medium and beat until completely smooth, about 3 minutes. If frosting is too stiff, add more milk. If it is too thin, add more powdered sugar. Add salt to taste.
- For more buttercream troubleshooting tips, see my book, The Home Baker's Guide to Basic Buttercream.
- Decorate cake as desired. Cake stays fresh covered at room temperature for up to 4 days. Cake may be covered and refrigerated for up to 7 days. Cake freezes well, up to 2 months. Wrap in plastic wrap, then in foil, then place in a large freezer bag or freezer-safe container. Thaw in the fridge overnight.
Notes
- Room temperature ingredients: it is imperative to use room temperature ingredients in this recipe. Allow ingredients to sit out at room temperature at least 45 minutes before beginning.
- Food coloring: I prefer gel food coloring. My favorite is AmeriColor.
- Cream: I strongly encourage using cream in this recipe. It keeps the crumb moist and dense and adds a creaminess to the overall texture of the cake.

Ahhh, how fun is this!? I am so stinking excited for this weekend, and my to-bake list just keeps growing. This one’s definitely being added!
I hope so! Thanks, Karly!
What a beautiful, beautiful cake Lynn! You got all those pretty swirls just right, I love it. The perfect way to celebrate 4th of July!
Thank you so much, Jess!
Hello! I’d like to make this cake for Saturday (it’s currently Thursday) and I’ll be traveling to my destination on Friday. How far ahead can it be made? Will it be good if I make it today or should I wait and whip it up once I get there? Thanks!
Hey, Allison! That would be totally fine to make it today. Keep it in the fridge, covered tightly. I would even put it on a plate and pop the pan back on top of it. Just save putting the frosting on top until Saturday, if you can. If you can’t, just wrap it tightly and keep it in the fridge like that.
Awesome, thanks!
HEY Lynn,
You’re cake looks AMAZING! So pretty!
I have everything on hand to make it, except for heavy cream. I do, however , have half and half . Could I substitute that and STILL have it come out right?
Thanks
Hi, Tracey! Using half-and-half should not affect the cake. Enjoy!
I baked this for Memorial Day and it was delicious and fun. You won’t regret making it!
I make a version of this cake 3-5 times a year now. Every. Single. Birthday! Easter, and whatever random community events we have. I just change the colors to whatever works for that child (3 under 6) or occasion and do two round layers for birthday’s! It’s delicious every single time! Even that time when I was out of cornstarch… and that time where I was running behind (ahem, 3 kids) and nothing was at room temp. I’m not saying I recommend staying from the directions… but I’m so thankful that we still ended up with a gorgeous and delicious cake when I did! Thank you so much for this recipe- it’s become a treasure in our home!
Hahaha, I TOTALLY understand those times, Jillian! This cake is definitely flexible, but those specific directions just yield the BEST results. I’m so glad you love this cake so much and that you change up the colors for your occasion!
I understand how you get rave reviews because when they’re not great, you delete them (as you did mine). Just to let you k now, we threw away 2/3 of the cake it was so horrible.
I didn’t delete your comment, Janet. I had to go looking for it in the spam, which is where actual comments go sometimes (positive and negative alike). It’s unfortunate this recipe didn’t work out for you, because it is a frequent one in our house! It’s actually adapted from my white layer cake, which is originally a recipe from Cooks Illustrated. I’ve also used this exact same batter to make sheet cake, rainbow cake, and champagne layer cake. So you can see you’re the first negative comment! Thanks for stopping by again to make sure I didn’t delete your comment, which would render my true reviews inauthentic.
My comment did not go to spam as I saw it right here on the screen. Nice try – but a lie nonetheless.
Well, that’s simply not true because any comment that comes in from a new IP address requires approval, so you may have seen it when you typed, but it didn’t stick around, I assure you of that. I’m not exactly sure what you’re trying to prove, Janet, but I have a screen shot of your comment in my spam folder that I’ll be emailing you. Truly, thank you for visiting!
I made this, with a few tweaks, on Memorial Day – it was delicious and beautiful!
Thanks so much, Sharon! So glad you enjoyed it.
I love the 4th of July and am always looking for fun desserts for our party. This is perfect!! The colors are so vibrant and the sprinkles make the dessert. Pinning for sure!
How cool that it swirls like that without your having to actually swirl it!
Right?! So fun!
What a fun and festive Bundt Cake! Perfect for any Patriotic holiday!
Would the colors still work if I did a regular bundt cake recipe?
Yes, this would work with any bundt cake recipe. But know that the white cake base will keep the colors truer since there will be no color interference.
I am a firm believer that holidays and celebrations need fun and festive desserts. This cake is perfection!
This cake is just gorgeous. I can’t wait to give it a try with my granddaughter this weekend. We’ll have even more fun eating a delicious slice.
Gorgeous cake! I cannot wait to try and make it, especially that swirl!
This cake looks amazing – the colors are swirled perfectly! So fun and festive and colorful!
This is quite the pretty bundt! So festive and colorful! And I can only imagine that it tastes just as good as it looks!
That is one beautifully swirled slice of cake! This is so much fun for the 4th of July!
I made this today to take to an outing. So very disappointed. I followed the directions exactly and I’m not a beginning baker. The cake only raised half way up in the pan. I’m so disappointed and trying to think of something else to make real quick as I only have a few hours left to finish
Hmm, that’s odd, considering the batter goes about 3/4 of the way up in the bundt pan before baking. It sounds like something didn’t go right with the preparation or the pan choice.
My kids (6 & 2) had so much fun making this recipe. The batter was so simple to throw together and mix. Their favorite part was adding the color to the batter to watch it change. Each step was written to take the guess work out for you. My taste testers agreed that this cake mix is by far better than boxed cake mix and takes almost the same amount of time. We can’t wait to make it again!
Thanks, Shannon! 🙂
