Let’s talk about these layers.

The bottom layer is a thick and chewy brownie, that is so rich and indulgent. A quick and simple recipe that uses melted butter, and cocoa powder. Do you like fudgy brownies? Then you’re gonna love these!

The top layer is a thick and creamy peanut butter fudge that only requires few ingredients. Simply melt butter and peanut butter together, add a little vanilla extract and salt, then add some icing/powdered sugar. So simple, yet so delicious!

    For the Brownies
  • 1 and 1/4 sticks (140g) unsalted butter, melted
  • 1 and 1/2 cups (300g) granulated sugar
  • 3/4 cup (75g) cocoa powder
  • 1/4 teaspoon salt
  • 2 teaspoons vanilla extract
  • 2 large eggs
  • 1/2 cup (60g) plain/all-purpose flour
  • For the Fudge
  • 1/2 cup (125g) smooth peanut butter
  • 1/2 cup (115g) unsalted butter
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla extract
  • 1 and 1/2 cups (190g) icing/powdered sugar
  • Chocolate chips, for topping


    For the Brownies
  1. Preheat the oven to 180C/350F/Gas 4. Line the bottom and sides of an 8x8 inch square baking pan with aluminium foil or parchment paper, and spray with baking spray. Set aside.
  2. Whisk together the butter, sugar, salt, and cocoa powder. Stir in the vanilla extract, then mix in the eggs, one at a time, stirring vigorously after each one. Fold in the flour until fully combined, stirring until thick and shiny.
  3. Pour the batter into the prepared pan, and spread out evenly. Bake for 30 - 35 minutes, or until a toothpick inserted into the centre comes out almost clean with a few moist crumbs. Allow to cool completely in the pan on a wire rack.
  4. For the Fudge
  5. Place the butter and peanut butter in a saucepan over medium heat, and stir often until melted and combined. Remove from the heat and stir in the salt and vanilla extract. Gradually add the icing sugar, stirring until combined. Spread the mixture on top of the cooled brownies, and smooth out evenly. Sprinkle some chocolate chips on top.
  6. Cover and refrigerate for at least an hour, until the fudge has set and is no longer warm. Once set, remove from the pan, cut into squares, and enjoy!


Brownies stay fresh, stored in an airtight container, in the fridge for up to 1 week. They also freeze well for up to 3 months. Thaw overnight in the fridge before serving.

  1. I just happen to LOVE fudgy brownies, so these babies are right up my alley! My goodness, Marsha, just when I think you’ve gone and made all of the most delicious treats ever, you whip out another and I’m just… gawking. Also, drooling. Also, totally daydreaming that I were your neighbor. These layers are so beautiful and spectacular. Hope you have an amazing week filled with PB fudge brownies, my friend. Happy Monday! 🙂
