Peanut-Butter Swirl Brownies

  • Brownies are one of those things that when I go out to eat I love to buy but I'd never really had them at home and I'd never baked any myself. So I found this recipe by Martha Stewart and decided that it was the best way to do some baking with peanut butter which my friend had been wanting to do since we started this and for me to try something new. 

    I can definitely say that the recipe tasted good, although it didn't have the same dense, fudgey-ness that makes up a brownie. The peanut butter filling (of which the recipe made too much) made the batter much lighter and closer to a dense cake than a brownie. 

    When we made the recipe we made a few mistakes (for what reasons I don't know) which I've bolded in the instructions so that no body else reading this will make the same mistakes. These lead to a slow and painful start of the baking process, however before we put it in the oven it looked great. I'm going to blame the amount of filling to batter ratio for what happened next and that was the peanut butter puffing up and covering the brownie batter making it take longer to bake and final product to break and fall  apart where the peanut butter swirls were.

    So I would conclude by saying that the brownies did not look as good as was planned, did not particularly taste like a brownie and were the source of quite a lot of frustration and a lot of salt spilling on the floor. But I would also say that they tasted really good and were a nice combination of creamy peanut butter and dense chocolate.  


    For the batter

    • 8 tablespoons (1 stick) unsalted butter, cut into small pieces, plus more for pan
    • 2 ounces good-quality unsweetened chocolate, coarsely chopped
    • 4 ounces good-quality semisweet chocolate, coarsely chopped
    • 2/3 cup all-purpose flour
    • 1/2 teaspoon baking powder
    • 1/4 teaspoon salt
    • 3/4 cup granulated sugar
    • 3 large eggs
    • 2 teaspoons pure vanilla extract
  • For the Filling

    • 4 tablespoons unsalted butter, melted
    • 1/2 cup confectioners' sugar
    • 3/4 cup smooth peanut butter
    • 1/4 teaspoon salt
    • 1/2 teaspoon pure vanilla extract


    Line a 8x8 pan with parchment paper.

    Place a bowl over a simmering pan of water. Coarsely chop chocolate and butter and stir in the bowl until melted. Let cool slightly.

    Whisk together flour, baking powder and salt (careful not to spill everywhere) in a separate bowl.

    Add sugar to chocolate mixture and stir until completely combined. Then add the eggs, stirring until each is combined. Add vanilla and then flour mixture. Stir until completely combined.

    Melt Butter (or in our case add hot water at the end) and mix with peanut butter, icing sugar, salt and vanilla, until smooth.

    Pour 1/3 of the brownie mixture into the square pan. Add spoonfuls of peanut butter on top and spaced evenly. Quickly run a knife through the batter to swirl them together. Add the rest of the brownie mixture and repeat steps with the peanut butter mixture. You probably won't have to use all of the peanut butter mixture because it tends to disfigure the brownies when baking. 

    Bake in the oven for 45 minutes at 325 degrees.
