Mint Brownies


Whenever I make these brownies I smile because they remind me of my best friend. They’re her favorite, and I wish I could ship her some, but they would be rocks by the time they arrived. Mint Brownies start with our Ultimate Fudge Brownies and then we top with a mint flavored American buttercream. The best part is all of the mint M&Ms and chocolate ganache on top. 🤤

If you choose to garnish with chocolate ganache, heat 100g heavy cream just to a simmer. Pour over 100g chopped chocolate. Let sit for 2-3 minutes and then whisk until smooth. Pour into a piping bag or Ziploc bag, cut the tip off the bag and drizzle over the frosted brownies.
