Ingredients

Scale
  • 1 box brownie mix (18 oz, e.g., Ghirardelli Double Chocolate)
  • Ingredients as listed on brownie mix (usually eggs, oil, water)
  • 1 cup unsalted butter, softened
  • 3–4 cups powdered sugar
  • 3–4 tablespoons heavy cream
  • 1 tablespoon pure vanilla extract
  • 1/4 teaspoon salt
  • Green food coloring (Wilton leaf green recommended)
  • Holiday sprinkles (including star sprinkles, nonpareils, colored sugar)
  • Non-stick spray for pan

Instructions

  1. Preheat oven to 350°F (180°C). Spray a mini muffin pan with non-stick spray.
  2. Prepare the brownie mix according to the box instructions.
  3. Fill each muffin cavity ⅔ full with brownie batter.
  4. Bake for 15–17 minutes, or until the edges are firm and a toothpick comes out with moist crumbs.
  5. Immediately after baking, use the back of a rounded spoon to press an indent in the center of each brownie to form a cup.
  6. Let brownies cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
  7. To make frosting: Cream softened butter on low speed until pale and fluffy.
  8. Gradually add powdered sugar and heavy cream, alternating between the two, mixing on low speed.
  9. Add vanilla, salt, and green food coloring. Mix on high speed for 2 minutes until smooth and well combined.
  10. Fill a piping bag with frosting using a closed star tip. Pipe frosting in swirls to form tree shapes on each brownie cup.
  11. Immediately decorate with holiday sprinkles before icing sets.

Notes

  • Cool brownies completely before frosting to avoid melting the buttercream.
  • Use a closed star tip for the best tree shape.
  • Add sprinkles right after piping to ensure they stick.
  • Store in a cupcake carrier or airtight container at room temperature for up to 5 days.
  • You can freeze undecorated brownie cups and frost them later.
