Ingredients
Method
Preheat and prep
- Preheat oven to 350F and line baking sheets with parchment. This prevents sticking and supports even spreading as the cookies bake.
Mix the dough
- Stir yellow or funfetti cake mix, vegetable oil, large eggs, and vanilla extract until a thick dough forms. Stop mixing once the mixture looks uniform and clings together.
Add mix-ins
- Fold in semi-sweet chocolate chips and rainbow sprinkles. Fold just until evenly distributed with no dry cake mix streaks.
Shape and bake
- Scoop 1 1/2-tablespoon balls onto the prepared sheets. Keep spacing so the cookies have room to spread.
- Bake 9-10 minutes until set but still pale. The centers should look slightly soft when you remove the tray.
Cool
- Cool for 5 minutes on the sheet. They firm up as they rest before you move them.
Notes
Pro tip: For consistent cookies, measure scoops the same size and keep the balls level. Store in an airtight container at room temperature up to 3 days, or refrigerate up to 5 days; freeze baked cookies up to 2 months. Dietary swap: use dairy-free chocolate chips for a dairy-free version without changing the method.
