339gramsReese’s Pieces, Peanut Butter M&Ms, chocolate chips, peanut butter chips, or any combination of them(1½ cups)
Chocolate Fudge Frosting:

227gramsconfectioner’s sugar(2 cups)
⅛teaspoonsalt
37gramshot milk
1½teaspoonsvanilla extract
113gramsunsalted butter, at room temperature(8 Tablespoons or ½ cup)
Instructions
Preheat oven to 350° F. Line an 9 inch springform baking pan with parchment paper.
In a 2-3 quart saucepan, melt the butter over low heat. Remove from heat and allow to cool to room temperature.
Mix in sugar and brown sugar. Stir in beaten eggs.
Mix in peanut butter and vanilla.
Mix in flour, baking soda and baking powder, just until fully incorporated and no flour is visible.
Stir in any mix-ins just until incorporated. Spread batter into prepared pan.
Bake for 50-55 minutes. The cookie cake is done when the edges are browned and a toothpick inserted in the middle comes out clean. Allow the cookie cake to cool completely in the pan. The middle will sink as it cools.
Frosting. In a bowl of an electric mixer (or bowl with a hand mixer), mix the cocoa powder, half the confectioner’s sugar and salt. Stir in the hot milk and the vanilla. Add the butter and rest of the confectioner’s sugar, beating until light and fluffy, approximately 2-3 minutes.
Assembly. Slide a metal spatula around the inside edge of the baking pan to loosen the blondie cake from the sides. Release the side portion of the springform pan. Using a spatula, lift the cookie cake onto a serving plate. Spread the frosting over the sunken part of the cookie cake.
Notes
You can use frozen, cold, or room temperature butter since you are melting it under the lowest heat possilbe anyway.
For a flaky top, mix in the sugars immediately after removing the butter from the heat, once it is melted. The heat from the butter will dissolve most of the sugar, which will help create a flaky top.
Make sure to allow the cookie cake to cool completely before removing it from the pan and frosting it.
