Ingredients
For the cake mix cookies
1/4 cup butter, softened
1 package (8 ounces) cream cheese
1 egg
1/4 teaspoon vanilla
1 package funfetti or rainbow chip cake mix
For for the filling (optional):
1 1/2 sticks of butter
1 teaspoon vanilla
2 to 4 cups confectioners’ sugar, depending on your desired consistency
Preparation
Preheat oven to 350°F. Note: the original cookie recipe called for 8 to 10 minutes at 375°F, but I found that baking slightly longer at 350°F worked better for my cookies. Cream the butter and cream cheese. Blend in egg and vanilla. Add cake mix in two parts, mixing well (it will be a super thick batter-if it is too stiff, add a small quantity of heavy cream to the batter and mix well). Using a small cookie scoop, drop balls of cookie dough on an ungreased baking sheet. Leave about 2 inches between the cookies. Bake for 8 to 12 minutes, or until lightly browned. Cool cookies for at least 15 minutes on the cookie sheet before transferring to a wire cooling rack; the cookies are very delicate when they first come out of the oven and they will break if you try to transfer them too soon. Once completely cool, add a generous dollop of frosting to the bottom of half the cookies, and then sandwich the rest of the cookies on top to form something that vaguely resembles a whoopie pie, but tastes like something else entirely. If you want the filling, go ahead and prepare it by mixing the butter until fluffy in your electric mixer; add the vanilla and then the confectioners’ sugar, bit by bit, until it has reached your desired consistency. Thin with cream or milk if desired, and adding a few drops of pink food coloring never hurts.
