Ingredients
Cookie Bar Batter
- 1 pouch (1 lb 1.5 oz) sugar cookie mix
- 1 box (15.25 oz) white cake mix
- 1 cup (2 sticks) butter, melted
- 3 large eggs
- 1 teaspoon vanilla bean paste
- 3 tablespoons rainbow sprinkles (non-pareils recommended)
Almond Buttercream Frosting
- 1/2 cup (1 stick) butter, softened
- 1½ cups powdered sugar
- 2-4 tablespoons milk (adjust as needed for consistency)
- Additional rainbow sprinkles for garnish
Instructions
- Preheat Oven: Heat your oven to 350℉. Prepare a 9×13-inch cake pan by spraying with cooking spray or lining with parchment paper for easy removal and cutting of the bars.
- Mix Batter: In a large mixing bowl, use an electric mixer on medium-high speed to beat together the sugar cookie mix, white cake mix, melted butter, eggs, and vanilla bean paste until well combined, about 1-2 minutes.
- Add Sprinkles: Gently fold in the rainbow sprinkles using a wooden spoon or spatula just a few times. Be careful not to overmix as this can cause the sprinkles to bleed color into the batter.
- Spread Batter: Drop large spoonfuls of the batter evenly over the prepared pan and spread it out carefully to fill the pan uniformly without piling it all in one spot.
- Bake: Place the pan in the oven and bake for 28-32 minutes, until the edges are golden brown and puffier than the center. Test doneness by inserting a toothpick into the center – it should come out clean without wet batter.
- Cool Bars: Allow the bars to cool completely in the pan, about 1 hour, before frosting.
- Make Frosting: Using an electric mixer, beat the softened butter until smooth and creamy. Gradually add powdered sugar and milk, starting with 2 tablespoons of milk, and beat until smooth and spreadable. Add more milk as needed for desired consistency.
- Frost Bars: Spread the almond buttercream frosting evenly over the cooled bars.
- Garnish and Serve: Sprinkle additional rainbow sprinkles over the frosting for a festive finish. Cut into squares and serve at room temperature or chilled.
Notes
- Be gentle when mixing in sprinkles to prevent colors from bleeding into the batter.
- Adjust the milk amount in the frosting to achieve your preferred spreading consistency.
- Using parchment paper makes it easier to lift out the bars for cutting and serving.
- These bars are delicious served chilled or at room temperature.
