Creating Crumbl Patriotic Cake Cookies is a straightforward process. Follow these steps for delicious results:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Prepare two baking sheets by lining them with parchment paper.
2. Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract. Mix until well combined.
4. Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, baking soda, and salt.
5. Mix Dry and Wet Ingredients: Gradually add the dry ingredients to the wet mixture. Stir until just combined.
6. Add Sour Cream: Fold in the sour cream until the batter is smooth.
7. Color the Dough: Divide the dough into three equal parts. Add red food coloring to one part, blue food coloring to another, and leave the third part plain. Mix each until the colors are well incorporated.
8. Scoop the Dough: Using a cookie scoop or tablespoon, drop spoonfuls of each colored dough onto the prepared baking sheets. Alternate the colors to create a fun marbled effect.
9. Bake: Place the baking sheets in the oven and bake for 12-15 minutes, or until the edges are lightly golden. Remove from the oven and allow to cool on the baking sheets for about 10 minutes before transferring to a wire rack.
10. Prepare the Frosting: In a small bowl, combine the powdered sugar and milk to create a smooth frosting. Adjust the consistency as needed.
11. Frost the Cookies: Once the cookies are completely cool, frost them with the prepared icing. Add sprinkles if desired for an extra festive touch.

By following these simple steps, you’ll create a batch of Crumbl Patriotic Cake Cookies that are both delicious and visually stunning!
