This buttery, crumbly peanut butter-infused shortbread creates a salty-sweet twist that appeals to both peanut butter fans and traditional shortbread lovers alike.
Preheat the oven to 325ºF (163ºC). Line an 8" round cake pan with parchment paper. Set aside.
In a small bowl, whisk together the flour, cornstarch, and salt. Set aside.
1 cup (120g) all-purpose flour, 2 Tablespoons (16g) cornstarch, ¼ teaspoon salt
In a medium size bowl with a handheld mixer or the bowl of a stand mixer fitted with the paddle attachment, beat the butter, peanut butter, brown sugar, and vanilla extract together on medium speed.
6 Tablespoons (85g) unsalted butter, ¼ cup (64g) creamy peanut butter1, ¼ cup (50g) firmly packed light brown sugar, 1 teaspoon vanilla extract
Slowly add the dry ingredients, then increase the mixer speed to high and beat for about 2-3 minutes until the mixture starts to clump. If using add-ins, add them and beat until evenly dispersed.
2 ounces (57g) add-ins3
Gather the shortbread dough with your hands and press it evenly into the prepared pan. Use a fork to dock the dough all over, then sprinkle the granulated sugar evenly over the dough.
1 Tablespoon (13g) granulated sugar2
Bake the shortbread for 28-30 minutes or until lightly browned. Remove the pan from the oven and allow to cool for 10-15 minutes in the pan. When slightly cooled, gently lift the parchment out of the pan, then use a sharp knife to cut the circle into 8, 12, or 16 even pieces. Allow the cookie slices to cool or enjoy warm. Store at room temperature up to 1 week. Slices freeze well, up to 3 months. Thaw at room temperature.
Notes
Creamy peanut butter: do not use natural style peanut butter. Feel free to use crunchy peanut butter, too!
Granulated sugar: 1 Tablespoon is just a guideline. Feel free to use more or less based on your preferences.
Add-ins: my suggestions are mini chocolate chips, toasted nuts, sprinkles, or chopped candy.
