1-First Step: Prepare the dough In a large bowl, beat the softened butter until creamy, about 1 minute. Add the cake mix, eggs, and vanilla extract. Mix on low speed until combined, then fold in the sprinkles gently to avoid breaking them. The dough will be thick and sticky, perfect for no-bake birthday cake cookies vibe but baked for chewiness. For gluten-free, confirm your mix works here.

2-Second Step: Portion the dough Scoop tablespoon-sized balls of dough (about 1.5 inches diameter) and roll them in powdered sugar until fully coated. Place them 2 inches apart on the prepared sheets. This step ensures even baking and that signature crinkle top on your festive birthday party cookies. Yield: about 24 cookies.

3-Third Step: Bake to perfection Bake for 9-11 minutes until edges are set but centers look soft. They firm up as they cool, staying chewy. Rotate sheets halfway for uniform results. Watch closely to avoid overbaking, especially for low-calorie versions with less fat.

4-Fourth Step: Cool and set Let cookies cool on the sheet for 5 minutes, then transfer to a wire rack. This prevents breakage and locks in moisture. For vegan adaptations, cooling time remains the same.

5-Fifth Step: Optional frosting and decorate Mix 1 cup powdered sugar with 2 tbsp milk and 1/2 tsp vanilla for glaze. Drizzle or frost cooled cookies. Add extra sprinkles for kids’ fun birthday cookies. Store as directed below.
