- Unsalted butter: The base for your frosting, providing richness and a silky texture.
- Powdered sugar: Sweetens and thickens the frosting to just the right consistency for spreading or piping.
- Heavy cream: Gives the frosting that smooth, creamy finish and helps achieve the perfect spreadable texture.
- Vanilla extract: Elevates the frosting flavor with its warm, aromatic notes.
- Green food coloring: Brings the festive green hue that makes these bites irresistible and perfect for the holiday.
- Pinch of salt: Balances the sweetness and boosts the overall flavor of both brownies and frosting.

- White chocolate chips or mini marshmallows (optional): Great for adding little bursts of sweetness and texture variations inside or on top.
How to Make St. Patrick’s Day Frosted Bite Brownies Recipe
Step 1: Prepare the brownie batter
Start by following your boxed brownie mix instructions, or if you prefer homemade, mix your favorite fudgy brownie batter. Combine the brownie mix, vegetable oil, eggs, water, and a pinch of salt in a bowl. For a minty flair, add ¼ teaspoon of peppermint extract now. Stir everything together until smooth and glossy, making sure not to overmix to keep that tender texture.
Step 2: Bake the brownies
Pour the batter into a lined or greased baking pan, spreading it evenly. Bake at the temperature recommended by your mix or recipe, generally around 25 minutes. Keep an eye on the brownies and check doneness by inserting a toothpick — it should come out with a few moist crumbs but no raw batter. Once baked, allow the brownies to cool completely to prepare for frosting.
Step 3: Make the minty green frosting
While the brownies cool, whip up the frosting. Beat softened unsalted butter with powdered sugar in a large bowl until smooth and fluffy. Gradually add heavy cream to get a spreadable texture. Stir in vanilla extract, a pinch of salt, and green food coloring until you achieve a joyful St. Patrick’s Day green. If you want more mint flavor, a tiny additional drop of peppermint extract can be added here.
Step 4: Frost and decorate the bites
Cut the cooled brownies into small, bite-sized squares. Use a palette knife or piping bag to frost each bite generously. Top with green sprinkles or shamrock decorations for that festive crunch. For an extra sweet pop, scatter a few white chocolate chips or mini marshmallows over the frosting before serving.

Garnishes
Green sprinkles and tiny shamrock decorations are classic garnishes that not only enhance the festive vibe but also add a playful textural contrast. You can also dust them lightly with edible glitter or give a swirl of white chocolate drizzle to create even more visual appeal.
Side Dishes
Pair these frosted brownie bites with a scoop of vanilla or mint chocolate chip ice cream for a decadent dessert. Fresh berries or a light fruit salad can provide a fresh counterbalance to the richness. A cup of Irish cream-flavored coffee or a cold glass of milk also complements these brownies perfectly.
Creative Ways to Present
Arrange the brownie bites on a themed platter lined with green tissue paper or a festive napkin. You can even stack them in mini cupcake liners to keep things tidy and inviting. For parties, a dessert board featuring these bites alongside pretzels, chocolates, and green candies makes for a colorful, interactive experience.
Make Ahead and Storage
Storing Leftovers
Keep any leftover St. Patrick’s Day Frosted Bite Brownies Recipe tightly covered in an airtight container at room temperature for up to three days. This helps maintain the moistness of the brownies and the freshness of the frosting without drying out.
Freezing
These brownie bites freeze beautifully! Place them in a single layer inside a freezer-safe container with parchment paper between layers to prevent sticking. Freeze for up to two months. When ready to enjoy, thaw them overnight in the fridge or at room temperature.
Reheating
Since these are frosted treats, it’s best to enjoy them cold or at room temperature. But if you want that warm brownie feeling, gently warm an unfrosted bite in the microwave for 10 to 15 seconds before frosting or top with some fresh frosting after warming.
FAQs
Can I use homemade brownies instead of boxed mix?
Absolutely! Homemade brownies work wonderfully and allow you to customize flavors and textures. Just be sure they’re fully cooled before cutting and frosting for the best result.
Is peppermint extract necessary for this recipe?
Not at all! The peppermint extract is optional and adds a lovely minty twist, but the brownies are fantastic without it if you prefer a classic chocolate flavor.
What can I use instead of green food coloring?
You can use natural alternatives like spinach or matcha powder for coloring, but keep in mind these might alter the taste and texture slightly. Gel food coloring typically gives the most vibrant and stable green.
How should I serve these at a party?
Serve the St. Patrick’s Day Frosted Bite Brownies Recipe on a festive platter or in mini paper cupcake liners. Pair them with complementary treats or drinks to create an inviting dessert station everyone will enjoy.
Can I make the frosting ahead of time?
Yes! The frosting can be made up to a day in advance. Store it covered in the fridge and bring it to room temperature before whipping it again to restore the creamy texture.
