Looking for the perfect treat to make for Cinco de Mayo? These Churro Cookies with Dulce de Leche Filling are the answer! They’re soft, chewy, and packed with that irresistible cinnamon-sugar flavor, with a creamy dulce de leche center that will have everyone coming back for more. No frying is required; it is just simple baking steps that anyone can follow.
In a large mixing bowl with the paddle attachment, cream the unsalted butter, granulated sugar, brown sugar, and vanilla extract at medium-high speed for 1 ½ minutes using a stand mixer or hand mixer. Mix in the egg and egg yolk until well combined.
In a separate bowl, whisk together the dry ingredients: flour, cornstarch, cinnamon, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined.
Scoop 1 tablespoon of cookie dough and roll it into small pieces, forming cookie dough balls. Make small wells in the top of each dough. Fill each indent with about ¾ teaspoon of chilled dulce de leche.
Take another 1 tablespoon portion of dough, create an indent, and place it over the filled cookie. Gently press the edges to seal, then roll it into a small ball to smooth it out.
When ready to bake, preheat your oven to 350 F. Place the cookies on a prepared baking sheet, 3 inches apart. Bake for 10–13 minutes or until the cookies are golden brown on the edges and slightly soft in the center.
