There’s something magical about holiday baking that brings families together, doesn’t there?

No complicated techniques here—just honest, delicious baking that reminds us of the joy in life’s simple pleasures.

I created these treats for my own family’s St. Patrick’s Day celebration last year, and let me tell you, they disappeared faster than a leprechaun’s gold! The combination of rich chocolate brownie, minty green frosting, and that playful rainbow sour belt peeking out creates something truly memorable.

Alternate Names & Variations

You might know these festive treats by other names depending on where you look. Some folks call them Leprechaun Brownie Bites, while others search for Rainbow Brownie Bars or Shamrock Brownie Bites. If you’re specifically looking for green brownies, this recipe absolutely delivers—just with an extra layer of chocolatey goodness underneath!

For variations, try swapping the chocolate frosting for cream cheese frosting dyed green, or use different colored sour belts to match other holidays. Some bakers like to add a drop of peppermint extract to the brownie batter itself for extra minty flavor, making them true mint brownies recipe style. You could also top them with crushed Andes mints for additional texture and that classic mint-chocolate combination everyone loves.

Ingredients for St. Patrick’s Day Brownie Treats

Here’s everything you’ll need to create these lucky little bites:

For the Brownie Base:

• 24 mini brownie bites (homemade using your favorite recipe or purchased from the bakery section)
• 1 batch of rich chocolate frosting (about 1½ cups)

For the Decorations:

• 24 rainbow sour belts (the chewy candy ropes in assorted colors)
• Wilton’s gold confetti sprinkles for that pot-of-gold finishing touch

For the Green Frosting (if making from scratch):

• ½ cup unsalted butter, softened
• 2 cups powdered sugar
• 2-3 tablespoons milk
• ½ teaspoon peppermint extract
• Green food coloring (gel works best for vibrant color)
• Pinch of salt

Step-by-Step Instructions

Step 1: Prepare Your Brownie Bites
If you’re making homemade brownie bites, prepare your favorite brownie recipe and bake in a mini muffin tin lined with paper cups. Allow them to cool completely before frosting—this is crucial! If using purchased brownie bites, simply arrange them on a serving tray or baking sheet lined with parchment paper.

Chef’s Tip: For the fudgiest texture, underbake your brownies by just 2-3 minutes. They’ll continue cooking as they cool and remain perfectly moist.

Step 2: Create the Green Frosting
In a large mixing bowl, beat the softened butter until creamy and smooth. Gradually add the powdered sugar, one cup at a time, alternating with small amounts of milk. Beat on medium-high speed until light and fluffy, about 3-4 minutes. Stir in the peppermint extract and a pinch of salt. Add green food coloring drop by drop until you achieve that perfect St. Patrick’s Day green. For a more natural look, try a shade somewhere between mint and shamrock green.

Shortcut Option: Short on time? Use store-bought vanilla frosting and simply tint it green with food coloring. Add ¼ teaspoon of peppermint extract to achieve that mint brownies recipe flavor profile.

Step 3: Frost the Brownie Bites
Using a small offset spatula or butter knife, spread a generous layer of green frosting on top of each brownie bite. Create a smooth, slightly domed surface for the best appearance. For a more professional look, transfer the frosting to a piping bag fitted with a star tip and pipe decorative swirls on each brownie.

Step 4: Add the Rainbow Accents
Take one rainbow sour belt and gently shape it into a curved arch, pressing one end into the frosting on one side of the brownie and the other end into the opposite side. The sour belt should form a rainbow arching over the brownie. Don’t worry about perfection—each rainbow will have its own charming character!

Step 5: Sprinkle with Gold
While the frosting is still soft, sprinkle Wilton’s gold confetti sprinkles generously over the green frosting. These represent the pot of gold at the rainbow’s end and add such a festive touch. The gold against the green creates that magical St. Patrick’s Day aesthetic we’re going for.

Step 6: Set and Serve
Allow the frosted brownie bites to sit at room temperature for about 15-20 minutes so the frosting can set slightly. This helps the rainbows stay in place. Arrange them on a festive platter and watch them disappear!

Why This Recipe Works & Expert Tips

What makes these St. Patrick’s Day Brownie Treats so special is their perfect balance of flavors and textures. The rich, chocolatey base provides that deep foundation that stands up beautifully to the cool, refreshing mint frosting. The rainbow sour belts add a chewy, fruity element that cuts through the sweetness, while the gold sprinkles bring a touch of elegance and that all-important holiday sparkle.

These treats qualify as easy comfort food for family dinners because they’re simple enough to make with your grandchildren yet special enough to serve at your most festive gatherings. The recipe is forgiving—you can use homemade or store-bought components, and the decorating process is more fun than fussy.

Expert Tips for Success:

• Room temperature ingredients matter: If making frosting from scratch, ensure your butter is truly softened for the smoothest, creamiest result.
• Color intensity: Gel food coloring gives you that vibrant green without thinning your frosting like liquid colors can.
• Make ahead: You can bake the brownie bites up to two days in advance and store them in an airtight container. Frost and decorate the day you plan to serve for the freshest appearance.
• Rainbow placement: If your sour belts are very stiff, microwave them for 5-6 seconds to make them pliable for shaping into arches.
• Serving suggestion: Arrange these on a mirror or shiny platter to reflect the gold sprinkles—it creates the illusion of real treasure!

Storage, Freezing, and Reheating Tips

Storage: These St. Patrick’s Day Brownie Treats keep well in an airtight container at room temperature for up to 3 days. If your kitchen runs warm, refrigerate them to prevent the frosting from becoming too soft. Just bring them to room temperature before serving for the best flavor and texture.

Freezing: You can freeze the unfrosted brownie bites for up to 3 months. Wrap them individually in plastic wrap, then place in a freezer bag. When you’re ready to use them, thaw at room temperature, then prepare the fresh green frosting and decorate. I don’t recommend freezing already-frosted brownies, as the texture of the frosting and candy rainbows will suffer.

Make-Ahead Strategy: For stress-free holiday prep, bake your brownie bites on March 15th, store them properly, make your frosting on the 16th (store in the refrigerator, then re-whip before using), and assemble everything on the morning of the 17th. This approach gives you green brownies that taste freshly made without last-minute chaos.

People Also Ask About St. Patrick’s Day Brownie Treats

How do you make green brownies?

Making green brownies is easier than you might think! The most popular method—and the one we use in this recipe—is to start with regular chocolate brownies and add a layer of green frosting on top. For the vibrant green color, use gel food coloring rather than liquid drops, as it provides richer color without changing the frosting’s consistency. You can tint either buttercream or cream cheese frosting, and adding a touch of peppermint extract complements the chocolate beautifully.

Some bakers also add green food coloring directly to brownie batter, but this can sometimes result in an unappetizing muddy color once baked. The frosting method gives you that picture-perfect bright green that says “St. Patrick’s Day”!

What flavor goes with St. Patrick’s Day?

Mint is the classic flavor associated with St. Patrick’s Day desserts, and for good reason! The cool, refreshing taste of mint pairs wonderfully with rich chocolate, creating that beloved combination we see in grasshopper pies, Thin Mints, and these brownie treats. Irish cream liqueur flavors also make frequent appearances in holiday baking, adding that grown-up touch to cheesecakes and truffles.

For non-alcoholic options, consider using Irish breakfast tea in frostings or glazes for a subtle, sophisticated flavor. Some bakers love incorporating actual Irish ingredients like Kerrygold butter in their recipes for authentic richness. The key is choosing flavors that feel both festive and familiar—mint chocolate hits that sweet spot perfectly for most celebrations.

How do you make mint brownies from scratch?

Creating mint brownies from scratch involves building layers of flavor throughout the baking process. Start with your favorite fudgy brownie recipe—one that uses melted chocolate rather than just cocoa powder tends to yield the richest results. While the brownies bake, prepare a mint buttercream by beating softened butter with powdered sugar, a splash of milk, and pure peppermint extract (start with ¼ teaspoon and adjust to taste).

For the most vibrant green color, use gel food coloring. Once brownies have cooled completely, spread the mint frosting evenly over the top. For that classic mint brownie finish, melt semi-sweet chocolate chips with a teaspoon of coconut oil and drizzle over the frosted layer. Chill until set, then cut into squares. The result is a three-layer treat with deep chocolate base, creamy mint center, and shiny chocolate top—absolutely irresistible!

What can I add to box brownies for St. Patrick’s Day?

Box brownies are a fantastic starting point for holiday creativity! For St. Patrick’s Day, try stirring in ½ cup of crushed Andes mints or mint chocolate chips into the batter before baking—this distributes minty pockets throughout. After baking and cooling, top with green-tinted frosting as described in our recipe, then add festive sprinkles in gold, green, and rainbow colors. For extra indulgence, press mini chocolate chips or white chocolate chips dyed green (toss with a drop of oil and food coloring) into the frosting.

You can also bake the brownies in a fun shape by using a shamrock-shaped cake pan or cutting cooled brownies with a cookie cutter. Another clever trick: layer green frosting between two thin brownie layers for a mint chocolate sandwich cookie effect. Box brownies are truly a blank canvas for your St. Patrick’s Day creativity!

Conclusion: Your Lucky Charm Dessert Awaits

These St. Patrick’s Day Brownie Treats have a way of bringing out the childlike wonder in all of us. There’s something genuinely heartwarming about watching faces light up when they spot those rainbow arches and gold sprinkles—it’s the kind of simple joy that makes holiday baking so rewarding.
