I'm a huge fan of anything with chocolate and peanut butter. Seriously, it's like the best combination in the world.

These chocolate peanut butter brownies are ridiculously delicious. The brownies are perfect on their own. They're soft and chewy and full of crunchy peanut bits. But then they're topped with creamy peanut buttery frosting AND drizzled in chocolate ganache AND sprinkled with a tiny bit of Maldon sea salt. OMG.

Instructions 

  • Preheat your oven to 350 degrees Fahrenheit. Line a 9×9 inch square baking pan with parchment paper and grease it with butter.

  • When the brownies are mostly cool, make the frosting. Use electric beaters to beat the peanut butter, butter, powdered sugar, and vanilla. Add 1 tablespoon of the milk and beat again. If you'd like a thinner frosting, add the second tablespoon. Spread the frosting over the brownies in the pan.

  • To make the chocolate topping, add the chocolate and cream to a medium-sized bowl and microwave for 1 minute. Stir until the chocolate is melted and smooth then pour it over the brownies. (Make sure that it's not hot when you pour it over!) Set the brownies aside for at least 30 minutes for the chocolate to set. Sprinkle a little sea salt over top then cut the brownies into 16 pieces.
