1 1/2 cups all purpose flour
1/2 cup unsweetened dutch process cocoa powder
1 1/2 teaspoons instant espresso powder
1/2 teaspoon salt
2 sticks unsalted butter
1 cup confectioners' sugar
1 teaspoon finely grated lime zest
1 teaspoon pure vanilla extract
Mix together flour, cocoa powder, espresso powder, and salt.
Mix together butter, powdered sugar, vanilla, and lime zest.
Beat together the butter mixture, you should get a smooth consistency, think lime buttercream.
Pour in the flour mixture. You should get a very crumbly mixture, but when you take a fistful of this mixture it should clump together and turn solid.
Roll the dough into small balls. Heat your oven to 350 and cook for 15 minutes.
Yummy - done! These are super easy and taste great.
