Ingredients
Base Cookie Bar Batter
- 15.25 oz box yellow or white cake mix
- 2 large eggs, room temperature
- ½ cup unsalted butter, melted and slightly cooled
- 1 teaspoon vanilla extract
Funfetti & Mix-Ins
- ½–1 cup rainbow sprinkles or pastel sprinkles
- ½ cup white chocolate chips or candy melts
- Optional: ½ cup pastel candy coated chocolates (like M&Ms)
Optional Icing (Sweet Finish)
- 1 cup powdered sugar
- 1–2 tablespoons milk or heavy cream
- ½ teaspoon vanilla extract
- Optional: additional sprinkles for decorating
Instructions
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or lightly grease it with butter or cooking spray.
In a large bowl, combine the cake mix, eggs, melted butter, and vanilla extract. Stir with a wooden spoon or spatula until the mixture is smooth and well combined
Don’t worry if it seems thicker than regular cake batter. That’s exactly what we want for chewy cookie bars!
Fold in the sprinkles, white chocolate chips or candy melts, and pastel candy coated chocolates (if using). Stir gently to distribute evenly without overworking the batter or melting the sprinkles.
Pour and spread the batter evenly into your prepared pan. Use a spatula to smooth the top and push the batter into all the corners.
Bake for 18–22 minutes, or until the edges are set and lightly golden, and a toothpick inserted in the center comes out clean or with just a few moist crumbs.
Allow the cookie bars to cool completely in the pan on a wire rack. This is CRUCIAL — cooling makes them firm up and easier to slice into clean squares.
In a small bowl, whisk together the powdered sugar, milk or heavy cream, and vanilla extract until smooth. Add more milk to thin or more powdered sugar to thicken as needed — you want a thick but pourable consistency.
Drizzle or spread the icing over the cooled bars using a spoon or piping bag. Add extra sprinkles on top before the icing sets for that festive Easter look!
Notes
- Prevent spreading: Make sure your melted butter has cooled to warm (not hot) before adding to prevent the bars from spreading too thin.
- Even distribution: When adding mix-ins, toss them in a bit of the dry cake mix first — this prevents them from sinking to the bottom.
- Bakery-style tops: Press extra sprinkles and chocolate chips onto the batter surface before baking for a gorgeous finish.
- Don’t skip cooling: Cutting warm bars = crumbly mess. Patience = perfect squares!
