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
- 1–2 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)
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Add Pretzel Stir Spoons: Insert a broken pretzel stick into each brownie cauldron to serve as a whimsical stirrer, completing the look.
- 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.
