They are absolutely perfect for serving at elegant cocktail parties, bridal or baby showers, potlucks, and any other social get-togethers where a unique and decadent treat is desired.

Our carefully crafted brownie recipe delivers a thick, intensely fudgy, and dense texture, providing the ideal foundation to complement the cool mint and rich chocolate layers. If you’re seeking a fantastic Gluten-Free Brownie option, we have you covered with an equally delicious alternative that won’t compromise on flavor or texture.

What Exactly Are Grasshopper Brownies?

Inspired by the classic creme de menthe flavored Grasshopper cocktail, these homemade chocolate brownies offer a sophisticated blend of mint and chocolate in a dessert form. Each bite delivers a chewy, rich chocolate experience, elevated by layers of cool, refreshing mint buttercream frosting and a glossy, decadent chocolate ganache. The flavor profile is strikingly similar to a beloved Andes Mint chocolate, transformed into an indulgent brownie experience that promises to captivate your taste buds.

The beauty of these grasshopper brownies lies in their distinct layers. The dense chocolate brownie base provides a robust foundation, while the light green mint frosting adds a burst of refreshing coolness, and the dark chocolate ganache provides a final layer of intense chocolate flavor and a smooth, luxurious finish. This trifecta of textures and flavors makes them truly unforgettable.

Essential Ingredients for Layered Perfection

Crafting the perfect Grasshopper Brownies requires specific ingredients for each layer, ensuring the right balance of flavor and texture. Here’s a detailed look at what you’ll need:

Homemade Fudgy Brownie Base

• Unsalted Butter: Melted butter is crucial for that signature fudgy texture. It also helps create a rich, dense brownie by dissolving the sugars effectively.
• Granulated Sugar & Light Brown Sugar: The combination of these two sugars creates a perfect balance of sweetness and moisture. Granulated sugar provides crisp edges, while brown sugar adds chewiness and a subtle molasses flavor.
• High-Quality Cocoa Powder: For the deepest, most intense chocolate flavor, opt for a good quality unsweetened cocoa powder. Dutch-processed cocoa will give a darker color and milder chocolate taste, while natural cocoa offers a more intense, slightly acidic chocolate flavor.
• Large Eggs (Room Temperature): Using room temperature eggs helps them emulsify better with the butter and sugar, leading to a smoother batter and a more even bake. If your eggs are cold, simply place them in a bowl of warm water for a few minutes.
• Pure Vanilla Extract: A touch of vanilla enhances the chocolate notes and adds complexity to the overall flavor of the brownies.
• All-Purpose Flour: This provides the necessary structure without making the brownies tough. Be careful not to overmix, as this can develop the gluten too much.
• Salt: A pinch of salt is vital to balance the sweetness and bring out the rich chocolate flavor.

Creamy Mint Buttercream Frosting

• Unsalted Butter (Softened): Softened butter is key for a smooth, lump-free buttercream. Allow it to sit at room temperature for at least an hour, or gently warm it in the microwave in short bursts until pliable.
• Pure Vanilla Extract: Adds a foundational flavor note to the frosting, complementing the mint.
• Peppermint Extract (Crucial!): Be sure to use peppermint extract, not spearmint or simply “mint” extract, for that authentic, cool grasshopper flavor. Peppermint has a distinct, strong, and refreshing taste that defines this dessert. Start with the recommended amount and add more to taste if you prefer a stronger mint.
• Whole Milk (or Cream): A small amount of liquid helps achieve the perfect consistency for spreading, ensuring the frosting is smooth and fluffy.
• Powdered Sugar (Confectioners’ Sugar): This fine sugar dissolves easily, creating a silky-smooth frosting without any grittiness.
• Green Food Coloring (Optional, but Recommended): A few drops of green food coloring give the frosting its iconic “grasshopper” appearance, making the brownies visually pop.

Luscious Chocolate Ganache Topping

• High-Quality Semi-Sweet Chocolate Chips or Bars: The quality of your chocolate will significantly impact the flavor and texture of your ganache. Semi-sweet is ideal, but you can experiment with dark chocolate for a less sweet ganache, or even use milk chocolate for a milder flavor. For an extra minty kick, consider using chopped Andes Mint Chocolates!
• Heavy Cream (Heavy Whipping Cream): This is essential for creating a rich, pourable ganache. The high-fat content of heavy cream yields a beautifully smooth and glossy finish.

How to Make Grasshopper Mint Chocolate Brownies: A Step-by-Step Guide

Making these layered brownies is a rewarding process. Follow these detailed steps to achieve perfect results every time:

1. Prepare Your Brownie Batter: Begin by preheating your oven to 350°F (175°C). In a large mixing bowl, combine the melted butter, granulated sugar, light brown sugar, salt, and cocoa powder. Whisk these ingredients together until they are fully incorporated and smooth. Next, add the room temperature eggs and vanilla extract, whisking until just combined. Gently fold in the all-purpose flour using a rubber spatula, mixing only until no dry streaks remain. Be careful not to overmix, as this can lead to tough brownies.
2. Bake the Brownie Base: Prepare your baking dish by lightly spraying it with non-stick cooking spray and then lining it with parchment paper, leaving an overhang on two sides for easy removal later. For thick, fudgy brownies like those pictured, use a 9-inch x 9-inch baking dish. If you prefer thinner brownies, a 9-inch x 13-inch pan can be used (adjust baking time accordingly). Pour the brownie batter evenly into the prepared dish and spread with a spatula.
3. Bake to Perfection: Bake the brownies in your preheated oven. For a 9-inch x 9-inch pan, this will take approximately 50-60 minutes. For a 9-inch x 13-inch pan, bake for about 30-40 minutes. The brownies are done when the edges appear crisp and a toothpick inserted into the center comes out with moist crumbs, but not wet batter. Avoid overbaking to maintain their fudgy texture. Remove from the oven and allow them to cool completely to room temperature on a wire rack before proceeding. This is crucial for layering the frosting and ganache without melting.
4. Whip Up the Mint Buttercream Frosting: While the brownies cool, prepare the mint frosting. In the bowl of a stand mixer fitted with the whisk attachment (or using a hand mixer), beat the softened room temperature butter until it’s light and fluffy. Stop the mixer, then add the vanilla extract, peppermint extract, half of the powdered sugar, and one tablespoon of milk. Beat again until light and fluffy. Add the remaining powdered sugar and milk, continuing to beat until the frosting is smooth, creamy, and voluminous. If desired, add a few drops of green food coloring and mix until the color is uniform and no streaks remain.
5. Frost the Cooled Brownies: Once the brownies are completely cool, spread the mint buttercream frosting evenly over the top using an offset spatula. Ensure an even layer for a beautiful presentation.
6. Prepare the Silky Chocolate Ganache: In a microwave-safe bowl, combine the semi-sweet chocolate chips and heavy cream. Heat in the microwave for 45 seconds. Remove and stir gently until the chocolate is completely melted and the mixture is smooth and glossy. If any chocolate bits remain, return to the microwave for additional 15-30 second intervals, stirring well after each, until fully smooth.
7. Top with Ganache: This is a critical step: allow the chocolate ganache to cool to room temperature before pouring it over the mint frosting. If the ganache is too warm, it will melt the frosting and create a messy result. Once cooled to a thick but still pourable consistency, carefully pour it over the mint frosting and spread it evenly to the edges.
8. Chill and Serve: For the best results and cleanest slices, allow the Grasshopper Brownies (or Grasshopper Bars) to chill in the refrigerator for at least 1-2 hours, or until the ganache is completely set. Once firm, lift the brownies out of the pan using the parchment paper overhang and slice them into desired bars or squares. Serve chilled and enjoy!

Pro Tips for Perfect Grasshopper Brownies

• Don’t Overmix: When making the brownie batter, stop mixing as soon as the flour is incorporated to avoid developing too much gluten, which can lead to tough brownies.
• Cool Completely: Patience is a virtue here! Ensure your brownies are entirely cool before adding the frosting, and the ganache is cooled before pouring it over the frosting. This prevents melting and creates clean, distinct layers.
• Room Temperature Ingredients: For the frosting, ensure your butter is genuinely at room temperature and soft. This helps achieve a smooth, creamy texture without lumps.
• Peppermint vs. Mint: Always use peppermint extract for the frosting. “Mint” extract can sometimes refer to spearmint, which has a different flavor profile that won’t give you the classic grasshopper taste.
• Achieving the Right Ganache Consistency: If your ganache is too thick after cooling, you can gently reheat it for a few seconds in the microwave and stir. If it’s too thin, let it cool longer, or even place it in the fridge for 5-10 minutes, stirring occasionally, until it reaches a spreadable consistency.
• Clean Slices: For perfectly neat squares, use a sharp knife and wipe it clean with a hot, damp cloth between each cut. Chilling the brownies thoroughly also aids in clean slicing.

Delicious Variations and Serving Suggestions

Variations

• Extra Chocolatey: Add a handful of chocolate chips or chopped dark chocolate to your brownie batter for an even more intense chocolate experience.
• Boozy Twist: For an adult-friendly version, add a tablespoon of crème de menthe liqueur to the frosting along with the peppermint extract (or instead of it, adjusting to taste) for an authentic cocktail-inspired flavor.
• White Chocolate Mint: Substitute semi-sweet chocolate in the ganache with high-quality white chocolate for a different visual and flavor contrast.
• Nutty Brownies: Incorporate chopped walnuts or pecans into the brownie batter for added crunch and flavor.
• Festive Sprinkles: Before the ganache sets, scatter some green or holiday-themed sprinkles over the top for an extra festive touch.

Serving Suggestions

• Chilled Perfection: Grasshopper Brownies are best served chilled, allowing the mint and chocolate flavors to meld beautifully and providing a refreshing bite.
• Coffee Pairing: These decadent brownies pair wonderfully with a hot cup of coffee, espresso, or a glass of cold milk.
• Ice Cream Treat: Serve a square of grasshopper brownie alongside a scoop of vanilla bean or mint chocolate chip ice cream for an ultimate dessert indulgence.
• Dessert Platter: Cut into smaller squares and arrange on a dessert platter with other treats for parties and celebrations.
