Perfect fudgy chocolate sugar cookies that don't need to chill and require no rolling or cutting. The perfect quick cookie when you need a last minute dessert or a chocolate fix.
Preheat the oven to 350℉. Line a baking pan with parchment paper and set aside. Add 1/4 cup sugar to a small bowl and set aside.
In the bowl of a stand mixer or large mixing bowl, add the butter and sugar. Beat together on medium speed for 3-4 minutes until creamed.
Add the egg and mix until incorporated. Add the vanilla and mix until incorporated.
Add the flour, cocoa powder, cornstarch, baking powder, baking soda and salt and mix until fully incorporated.
Scoop 2 tbsp size cookies. Roll them into a ball and then roll them in the sugar we set aside earlier. Set them on the pan at least 2 inches apart and bake for 8-10 minutes, or until the edges just start to feel firm.
Transfer the cookies to a wire rack to fully cool. Store in an airtight container for up to 3 days and enjoy!
