Festive Easter Cookie Cake made with rich butter, brown sugar, and chocolate chips that come together to form a soft, chewy base. A vanilla buttercream frosting rings the edges with chocolate eggs, a perfect dessert for Easter!
Prep: Preheat the oven to 350°F. Then spray an 8-inch springform pan with nonstick spray and set aside.
Batter: In a large mixing bowl, use an electric mixer to beat the butter, brown sugar, and sugar until light and creamy. Add in the egg, egg yolk, and vanilla extract; continue to mix for 1 minute.
Stir in the flour, cornstarch, and baking soda and mix again until combined. Then fold in the chocolate chips and Cadbury eggs until just combined, be careful not to overmix.
Bake: Spread the cookie dough into the prepared springform cake pan and place in the preheated oven to bake for 20-25 minutes, until golden brown. Let the cookie cool for about 20 minutes, then run a knife around the edge and release the springform pan.
Frosting: Combine the butter, vanilla extract, and powdered sugar, mixing with an electric mixer until it's light and fluffy. Then separate the frosting into 4 bowls and continue to dye one bowl pink, blue and yellow, while keeping one bowl white.
Pipe the frosting in alternating colors and top each frosting dollop with the corresponding Cadbury egg color. Slice into wedges, serve, and enjoy!
Notes
Left over Easter cookie cake will last up to 3-5 days, if kept stored in an airtight container. I recommend keeping any leftovers stored in the fridge once frosted, but they will be fine at room temperature too.
