Brownie Cookie Sandwich with Nutella Filling

Brownie Cookie with Nutella Filling

For the Brownie Cookie:

  • 1 package brownie mix
  • 1 egg
  • 2 tbsp water
  • 1/3 cup oil

For the Frosting:
(Used the frosting recipe from http://sallysbakingaddiction.com/2013/03/14/chocolate-cupcakes-with-creamy-nutella-frosting/)

  • 1 cup (230g) unsalted butter, softened to room temperature
  • 2 cups (240g) confectioners' sugar
  • 3/4 cup (222g) Nutella
  • 3-4 Tablespoons (45-60ml) heavy cream*
  • 2 teaspoons vanilla extract
  • salt to taste

Make the brownie cookie: Preheat oven to 350 degrees F.

Mix the brownie mix, egg, water, and oil. Mixture should be doughy. Place cookie-sized dough on a greased cookie sheet. Bake for 10-12 minutes or when the middle of the cookies begin to rise.

Make the frosting: Beat softened butter on medium speed with an electric or stand mixer. Beat for 2-3 minutes until smooth and creamy. You want a very creamy base before adding anything else. See my extensive notes about this in the post above. Add 2 cups of powdered sugar and continue to beat on medium speed. The mixture will be fairly thick. Add the Nutella and continue to beat on medium speed. Add 3 Tablespoons of heavy cream and the vanilla extract. If the frosting is too thick, add more heavy cream (1 Tablespoon measurements at a time). If the frosting is too thin, add more powdered sugar (1/4 cup measurements at a time). Taste the frosting and add salt to cut the sweetness. I added about 1/4 teaspoon of salt to mine.

Just some notes on the frosting: Not as much Nutella was used since the cookies themselves were already going to be rich.

Another suggestion is to serve these cookies cold from the fridge.
