Ingredients

LayerIngredients
Brownie Layer
  • 3/4 cup (1 1/2 sticks) unsalted butter, plus more for greasing
  • 1 1/2 cups packed fresh mint sprigs, torn
  • 2 ounces bittersweet chocolate, chopped
  • 2 large eggs
  • 1 cup unsweetened cocoa powder
  • 1/3 cup all-purpose flour
  • 1/4 teaspoon kosher salt
  • 1/4 cup peppermint schnapps
Mint Buttercream Layer
  • 1/2 cup (1 stick) unsalted butter, at room temperature
  • 2 1/2 cups confectioners’ sugar
  • Pinch kosher salt
  • 1/4 cup peppermint schnapps
  • Green gel food coloring
Truffle Layer
  • 1/2 cup plus 2 tablespoons (10 tablespoons) unsalted butter
  • 6 ounces bittersweet chocolate, chopped
  • Sprinkles (optional, for garnish)

Step-by-Step Instructions

1. Prepare the Brownie Layer

  • Grease and line an 8-inch square baking pan with parchment, leaving an overhang for easy removal.
  • Melt the butter over low heat in a saucepan, then add torn mint sprigs and infuse for 10 minutes off the heat.
  • Strain out the mint leaves, pressing gently to extract all flavored butter.
  • Rewarm the mint-infused butter. Remove from the heat and add chopped bittersweet chocolate, letting it melt. Stir until smooth.
  • In a separate bowl, whisk together unsweetened cocoa powder, all-purpose flour, and kosher salt.
  • Whisk eggs into the chocolate butter mixture until smooth.
  • Add dry ingredients and stir until just combined.
  • Add peppermint schnapps for minty flavor, then mix until smooth.
  • Transfer batter to the prepared pan. Smooth into an even layer.
  • Bake at 350°F (175°C) for 28–30 minutes, until the center is just set (a tester may look fudgy).
  • Cool completely before adding the mint buttercream layer.

2. Make the Mint Buttercream Layer

  • Beat softened unsalted butter with powdered sugar and a pinch of kosher salt until creamy.
  • Add peppermint schnapps for added flavor.
  • Mix in green gel food coloring to achieve the desired intensity (a dark sage is ideal for contrast).
  • Spread buttercream over cooled brownie base in an even layer. Chill to set before adding the truffle topping.

3. Prepare and Add the Truffle Layer

  • Melt butter and chopped bittersweet chocolate in a saucepan over low heat until smooth.
  • Cool slightly to prevent melting the buttercream layer.
  • Spread the chocolate truffle mixture gently over the chilled mint layer.
  • Sprinkle with festive decorations (optional), such as holiday sprinkles, for added visual flair.
  • Chill until fully set, then lift bars from the pan using the parchment overhang and slice into squares.

Expert Tips for Perfect Peppermint Bars

  • Use fresh mint sprigs for a robust, natural flavor infusion in the brownie base.
  • Peppermint schnapps gives both mint layers a vibrant kick. If you prefer a non-alcoholic version, substitute with peppermint extract.
  • Gel food coloring offers a vivid color without thinning out the buttercream.
  • Let each layer cool/set fully before adding the next to prevent mixing and ensure clean lines when slicing.
  • Parchment paper overhang makes removing bars from the pan simple and preserves layers intact.

Serving Suggestions

  • Pair these bars with hot cocoa, coffee, or holiday cocktails for a delightful dessert experience.
  • Arrange on a platter and sprinkle with crushed peppermint candies or edible glitter for festive presentations.
  • Serve chilled for the best texture—especially the buttercream and truffle layers.
  • Wrap individual slices in parchment or cellophane for gifts or party favors.

Variations & Customizations

  • Non-Alcoholic Alternative: Substitute peppermint schnapps with peppermint extract—use 1 teaspoon per layer for similar flavor intensity.
  • Chocolate Choice: Try semi-sweet or dark chocolate for a stronger cocoa profile in the brownie or truffle layers.
  • Decorative Toppings: Crushed candy canes, mini chocolate chips, or colored nonpareils can add visual and textural interest.
  • Nut Addition: Stir toasted walnuts or pecans into the brownie base for crunch.
  • Gluten-Free Option: Substitute all-purpose flour with a gluten-free baking blend.

Storage and Make Ahead

  • Refrigeration: Store bars in an airtight container in the refrigerator for up to 5 days.
  • Freezing: Peppermint bars freeze well; wrap individual slices for up to 2 months. Thaw in the fridge before serving.
  • Make ahead: All layers hold up well to refrigeration, making this an ideal dessert to prepare 1–2 days in advance.

Frequently Asked Questions (FAQs)

Can I use peppermint extract instead of schnapps?

Yes, substitute 1 teaspoon of peppermint extract in place of each 1/4 cup of schnapps for both the brownie and buttercream layers.

How do I know when the brownie base is done baking?

Bake until the center is just set. A toothpick inserted will appear moist but not liquid; avoid overbaking for a fudgy texture.

What is the best way to cut clean squares?

Chill bars until firm, then use a sharp, warm knife (wiped clean between cuts) to slice without smudging the layers.

Can I freeze peppermint bars for later?

Yes, they freeze well. Place slices between layers of parchment and store in an airtight container for up to two months. Thaw in the refrigerator prior to serving.

Do I have to use fresh mint in the brownies?

Fresh mint adds depth but you can substitute with 1/2 teaspoon mint extract in the butter for similar flavor.

Quick Troubleshooting Tips

  • Buttercream melting or sliding: Ensure the brownie base is fully cooled before spreading buttercream. Chill each layer as directed.
  • Truffle layer not setting: Chill longer or refrigerate briefly to firm up chocolate.
  • Browning edges: Cover pan loosely with foil for the last 10 minutes if edges cook faster than the center.
