The base of your frosting, adding richness and creaminess.
Powdered Sugar
This gives the frosting its smooth, sweet texture.

Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a mini muffin tin with paper liners or lightly grease it to ensure your brownies come out easily.
Step 2: Prepare the Brownie Batter
Follow the instructions on your brownie mix box to prepare the batter, adding eggs, oil, and water as required. If you’re making homemade brownies, whisk together the ingredients for the batter, ensuring everything is combined well.
Step 3: Fill the Muffin Tin
Spoon the brownie batter into the mini muffin tin, filling each cup about 2/3 of the way. Bake according to the package instructions (usually around 10-12 minutes). Check doneness by inserting a toothpick—it should come out with a few moist crumbs, not wet batter.
Step 4: Let the Brownie Bites Cool
Once baked, remove the brownie bites from the oven and let them cool in the tin for 5 minutes. Then, transfer them to a wire rack to cool completely before frosting. This ensures the frosting won’t melt when you apply it.
Step 5: Prepare the Frosting
In a medium bowl, beat together softened butter, powdered sugar, milk, and vanilla extract until smooth and creamy. Add a few drops of green food coloring and mix until the frosting reaches your desired shade of green.
Step 6: Frost the Brownie Bites
Once the brownie bites are completely cool, spread a generous amount of frosting on top of each bite. Use a small offset spatula or the back of a spoon for an even layer. Don’t forget to get creative—sprinkles or gold dust can give it an extra festive touch!
Step 7: Serve and Enjoy
These brownies are ready to be devoured! Serve them up at your St. Patrick’s Day party, pack them in lunchboxes, or just enjoy them as an afternoon treat. Each bite is like a little burst of luck!

- ½ cup vegetable oil (or as instructed on the brownie mix box)
- 2 large eggs
- 2 tbsp water (or as instructed on the brownie mix box)
- ¼ tsp peppermint extract (optional for a minty twist)
For the frosting:

- 1 tsp vanilla extract
- ½ tsp green food coloring (gel or liquid)
- A pinch of salt
For garnish (optional):
- Green sprinkles or shamrock decorations
- White chocolate chips or mini marshmallows (optional)
Instructions
- Prepare the brownies:
Preheat your oven to 350°F (175°C). Prepare the brownie mix according to the instructions on the box. If you’re using a homemade brownie recipe, follow the instructions for baking. - Bake the brownies:
Grease a 9×9-inch square baking pan or line it with parchment paper. Pour the brownie batter into the prepared pan and bake according to the instructions on the box (usually about 20-25 minutes). If you’re using a homemade recipe, follow the baking time listed in the recipe. To check for doneness, insert a toothpick into the center of the brownies—if it comes out with a few moist crumbs, they’re done. - Cool the brownies:
Once the brownies are done baking, remove them from the oven and let them cool completely in the pan on a wire rack. - Make the frosting:
In a mixing bowl, beat the softened butter with an electric mixer until smooth. Gradually add the powdered sugar, one cup at a time, until fully incorporated. Add the heavy cream, vanilla extract, and a pinch of salt, and continue to beat until the frosting is fluffy and smooth. Add the green food coloring, a little at a time, until you achieve your desired shade of green. - Frost the brownies:
Once the brownies have cooled, spread the green frosting evenly over the top using a spatula. You can make it smooth or add a little swirl effect for extra flair. - Cut into bite-sized pieces:
Using a sharp knife, cut the frosted brownies into small bite-sized squares or rectangles, perfect for sharing. - Garnish and serve:
Optionally, garnish with green sprinkles, white chocolate chips, mini marshmallows, or shamrock decorations for an extra touch of St. Patrick’s Day fun!
