Servings: 8 slices
Ingredients
For the cookie cake:
- ½ cup unsalted butter melted
- ½ cup light brown sugar
- ¼ cup granulated sugar
- 1 egg room temperature
- 2 tsp vanilla extract
- 1 tbsp corn starch
- 1 ½ cups all-purpose flour
- ½ tsp baking soda
- ½ tsp kosher salt
- ⅓ cup rainbow sprinkles
For the buttercream
- 4 tbsp unsalted butter room temperature
- 1 ¼ cups powdered sugar
- ½ tsp vanilla extract
- 2 tbsp heavy cream room temperature
Instructions
For the cookie cake:
- In a mixing bowl, whisk together the melted butter, light brown sugar, and granulated sugar until smooth and combined. Add the egg and vanilla extract, and mix until fully incorporated.
- Stir in the corn starch, flour, baking soda, and salt until just combined. Be careful not to overmix. Gently fold in the rainbow sprinkles. Preheat the air fryer to bake at 325°F or alternatively preheat the oven to 325°.
- Lightly grease an 8 inch springform pan or cake pan that fits inside your air fryer basket. Press the cookie dough evenly into the prepared pan.
- Once preheated, bake for 25 minutes or until the edges are lightly golden and the center is just set. Allow the cookie cake to cool in the pan for 10–15 minutes before removing.
For the frosting:
- In a small bowl, beat the salted butter until creamy. Gradually add the powdered sugar, mixing well after each addition. Stir in the vanilla extract and 1 tbsp of heavy cream. Add more cream as needed to reach your desired consistency. Mix in a pinch of salt to balance the sweetness.
For assembly:
- Transfer the frosting to a piping bag fitted with a star tip or any preferred tip. Pipe a decorative border around the cooled cookie cake. Add extra sprinkles on top if desired for a festive touch. Slice into wedges and serve! Perfect for celebrations like New Year’s Eve or any fun occasion.
