Directions

Make the Brownies:

Make the Mint Buttercream:

  1. Beat the butter for 1-2 minutes in a stand mixer. Add powdered sugar and mix until combined.
  2. Adjust consistency: Add milk or heavy cream 1 tablespoon at a time until smooth and spreadable. Mix in peppermint extract and green food coloring, if using.
  3. Spread over the cooled brownies and refrigerate until firm.

Make the Chocolate Ganache:

  1. Finely chop the chocolate and place it in a heatproof bowl.
  2. Heat the cream: In a saucepan, bring the heavy cream to a simmer (do not boil). Pour over the chopped chocolate and whisk until smooth.

FAQs

Can I use milk chocolate instead of bittersweet chocolate?

Yes, but bittersweet chocolate balances the sweetness better.

How do I get clean cuts when slicing the brownies?

Use a sharp knife, wipe it clean between cuts, and chill the brownies before slicing.

Can I skip the green food coloring?

Yes! It’s just for color and won’t affect the flavor.

Increase the peppermint extract slightly, but be careful—it can become overpowering.

Use the correct cream-to-chocolate ratio and store at room temperature before serving.

Can I use regular mint extract instead of peppermint extract?

Peppermint extract is preferred, but mint extract will also work.

What’s the best way to serve these brownies?

Serve chilled for a firmer texture or at room temperature for a softer bite.
