Ingredients

  • 1 cup granulated sugar
  • ⅓ cup light brown sugar tightly packed
  • 10 tbsp unsalted butter melted
  • ¾ cup cocoa powder
  • 1 tsp vanilla extract
  • 2 eggs
  • 1 egg yolk
  • ½ cup gluten free flour
  • 1 tbsp tapioca flour
  • 1 cup chocolate frosting
  • ¼ cup Rainbow sprinkles

Instructions

    Cup of Yum
  1. First, preheat your oven to 350 degrees Fahrenheit. Line an 8 inch square pan with parchment paper.
  2. In a large bowl, combine the sugar, light brown sugar, melted butter, and cocoa powder. Stir vigorously for 2 minutes.
  3. Then, add in the vanilla, eggs, and egg yolk. Stir to combine.
  4. Add in the gluten free flour and tapioca flour. Stir until a slightly thick brownie batter forms.
  5. Transfer the batter to the prepared pan. Smooth into an even layer.
  6. Bake for 24 to 27 minutes, or until a toothpick inserted comes out with only a few moist crumbs.
  7. Once the brownies have fully cooled, top with chocolate frosting and sprinkles. Refrigerate for 1 hour, or until the frosting has firmed up and set.
  8. Finally, slice and serve!

Notes

  • Stir the melted butter mixture for 2 minutes.  This is key in achieving the shiny top on the brownies.
  • Use 2 whole eggs and an additional 1 egg yolk.
  • If you are not gluten free, feel free to use regular all purpose flour.
  • If needed, replace tapioca flour with cornstarch.
  • The brownies are done baking when a toothpick inserted comes out mostly clean with a few moist crumbs.
  • The brownies must cool fully before topping with frosting.
  • Place the frosted brownies back in the fridge to allow the frosting to thicken.
  • Store leftovers in an airtight container for up to 4 days at room temperature.
  • Store in the fridge for up to one week.
