Ingredients

Scale

Brownies

  • 1 box brownie mix plus the ingredients listed on the back
  • 1/2 cup (113g) butter (1 stick, room temperature)
  • Non-stick cooking spray

Buttercream Frosting

  • 12 cups (113-227g) powdered sugar
  • 1/2 cup (113g) butter (1 stick, room temperature)
  • Green food coloring (Leaf Green Wilton gel food coloring recommended)

Decorations

  • Large green nonpareil sprinkles
  • Small green nonpareil sprinkles
  • Broken pretzel sticks (for stir spoons)

Instructions

  1. Preheat and Prepare Brownie Batter: Preheat your oven according to the brownie mix package instructions. Prepare the brownie batter as directed on the box, ensuring a smooth consistency.
  2. Fill Mini Muffin Pan: Spray a mini muffin pan with non-stick cooking spray. Fill each muffin well about two-thirds full with the brownie batter to allow space for rising.
  3. Bake Brownies: Bake in the preheated oven for 10-15 minutes, or until a toothpick inserted in the center comes out clean. Do not overbake to keep them moist.
  4. Create Cauldron Indentations: Remove the muffins from the oven and while still warm, use a 1/2 tablespoon to create indentations or ‘cauldron wells’ in each brownie. Allow the brownies to cool completely before removing them from the pan to maintain their shape.
  5. Make Green Buttercream Frosting: Beat the 1/2 cup of butter with an electric mixer for about 30 seconds until smooth and creamy. Gradually add 1 to 2 cups of powdered sugar, beating well after each addition to reach a thick but spreadable consistency. Add a small amount of green gel food coloring and beat until the color is evenly mixed and vibrant.
  6. Fill Brownie Cauldrons: Use a spoon to dollop the green buttercream into the indentations of each brownie, creating a bubbling cauldron effect. With the spoon, make swirling wisps in the frosting to resemble magical steam or mist.
  7. Decorate with Sprinkles: Sprinkle large and small green nonpareils onto the buttercream to mimic cauldron bubbles. For a bubbling-over effect, spread some frosting down the sides of the brownie and add sprinkles there as well.
  8. Add Pretzel Stir Spoons: Insert a broken pretzel stick into each brownie cauldron to serve as a whimsical stirrer, completing the look.
  9. Serve or Store: Serve immediately or store on the counter if consuming the same day. For longer storage, place brownies in an airtight Tupperware container until ready to serve.

Notes

  • You can adjust the amount of green food coloring to get the desired shade of buttercream.
  • Use a mini muffin pan for perfectly sized brownie bites that resemble cauldrons.
  • If you don’t have nonpareil sprinkles, you can substitute with other green sprinkles or edible glitter for extra sparkle.
  • Allow brownies to cool completely before applying buttercream to avoid melting.
  • These treats keep well stored in an airtight container at room temperature for up to 3 days.
  • For a dairy-free version, substitute the butter with a plant-based margarine and use a dairy-free brownie mix and powdered sugar.
