Preheat oven to 350℉. Liberally spray a mini muffin pan with baking spray.
Separate the premade chocolate chip cookie dough squares and place one section into each well of the mini muffin tins.
1 16.5- ounce package chocolate chip cookie dough
Bake for 16-18 minutes or until golden brown.
Immediately after baking, use the small end of a tart shaper or a wine cork to lightly press the centers down, forming a cup shape.
Let cookies cool in the pan for about 5 minutes, then carefully lift them out using a butter knife. Transfer to a cooling rack to cool completely.
To make the frosting, beat unsalted butter in a large bowl on medium speed for 2-3 minutes until light and pale in color.
½ cup unsalted butter
Add powdered sugar, cocoa powder, vanilla extract, and a dash of salt. Mix on medium speed, adding 1-2 tablespoons of heavy cream until the desired consistency is reached. Beat for an additional 2-3 minutes until fluffy.
1 ½ cups powdered sugar, ¼ cup unsweetened cocoa powder, 1-2 Tablespoons heavy whipping cream or milk, 1 teaspoon vanilla extract, Dash of salt
Transfer the frosting to a piping bag and pipe it into the cooled mini cookie cups. For extra flavor, top with sprinkles or mini chocolate chips!
