This blueberry tea cake is soft, fluffy, and bursting with blueberry flavor, thanks to a simple homemade blueberry swirl. Unlike cakes made with whole blueberries that sink to the bottom, this recipe ensures even distribution of full-bodied blueberry flavor for a perfect bite every time.

Instructions
BLUEBERRY SWIRL
In a small saucepan, combine the blueberries, sugar, and water. Stir to combine, then heat over medium heat while stirring until juices start to seep out of the blueberries.
1 cup fresh blueberries1, 3 Tablespoons (38g) granulated sugar, 2 Tablespoons (30mL) water
Use a spoon, fork, or spatula to break the blueberries as they cook, taking care that all of them are broken.
Reduce the temperature to medium-low and continue cooking and stirring until the mixture is at a simmer. Allow to simmer for 5 minutes while stirring frequently as the mixture thickens. Remove from the heat and allow mixture to cool for 15 minutes while you work on the cake batter.
In a small bowl, whisk together the flour, baking powder, and salt. Set aside.
1 and ¾ cups (210g) all-purpose flour, 2 teaspoons baking powder, ½ teaspoon salt
In a large bowl with a handheld mixer or the bowl of a stand mixer fitted with the paddle attachment, cream the butter and sugar together on medium-high speed until light in color and fluffy in texture (about 2-3 minutes).
½ cup (113g) unsalted butter, 1 cup (200g) granulated sugar
Add the eggs one at a time, continuing to beat until combined. Add the vanilla, then beat again until fully incorporated. Turn off the mixer, then scrape down the sides and bottom of the bowl with a large spatula.
2 large eggs, 2 teaspoons vanilla extract
Turn the mixer to low speed, then add the dry ingredients in 3 additions alternating with half of the milk, starting and ending with the dry ingredients.
½ cup (120mL) milk2
Stop the mixer when the last bit of flour has just been incorporated, then use a large spatula to gently fold the batter together until no flour pockets remain.
Pour about half of the batter into the prepared pan, then drop dollops of about two-thirds of the cooled blueberry mixture onto the batter. Add the remaining half of the tea cake batter followed by the remaining third of the blueberry mixture, then use a butter knife to swirl the batter around in the pan.
Bake the cake for 38-40 minutes, or until a toothpick or cake tester inserted in the center comes out mostly clean. Allow to cool completely before serving. Store leftovers covered tightly at room temperature up to 3 days or in the refrigerator up to 5 days. Cake freezes well, up to 3 months. Thaw in the refrigerator or at room temperature.
Notes
Blueberries: you can also use frozen blueberries. No need to thaw.
Milk: I prefer whole cow milk when baking, but you can use any milk here that you prefer.
