– 12 TBSP butter softened – 1 cup brown sugar – ¼ cup sugar – 1 egg – 1 egg yolk – 2 tsp vanilla extract – 1 ¾ cup flour – 1 tsp cornstarch – 1 tsp baking soda – ½ cup chocolate chips – ½ cup red, white & blue M&M candies
In a large mixing bowl, beat the butter, brown sugar, and sugar until light and creamy.
After that, add in the egg, egg yolk, and vanilla extract; continue to mix for 1 minute.
Proceed to stir in the flour, cornstarch, and baking soda and mix again until combined.
Then stir in the chocolate chips until just combined, be careful not to overmix.
Spread the cookie dough into the prepared springform cake pan and top with the M&M candies, gently pressing them into the top. Bake for 20-25 minutes, until golden brown.
Prepare the icing by combining the butter, vanilla extract, and powdered sugar, mixing until the mixture is light and fluffy. Again, using an electric mixer helps greatly with this step.
