Peanut Butter Swirl Brownies - from Martha Stewart
Makes 16, 2 inch square brownies
Preheat the oven to 325
For the Brownie Batter
1 stick butter, cut into pieces
2 ounces unsweetened chocolate
4 ounces (1/2 cup) chocolate chips
2/3 cup flour
1/2 teaspoons baking powder
1/4 teaspoon salt
3/4 cup sugar
3 large eggs
2 teaspoons vanilla
For the Peanut Butter Filling
1/2 cup melted butter
3/4 cup peanut butter
1/4 teaspoon salt
1/2 teaspoon vanilla
Grease an 8 inch square baking dish, line with parchment and grease the bottom only of the parchment.
In a double boiler (or a bowl over a pan of simmering water) melt the butter and the chocolates stirring occasionally. When the chocolate is all melted, let the mixture cool a bit.
While the chocolate cools, in a separate bowl whisk together the flour, salt and baking powder.
Next, mix together the peanut butter filling ingredients in a small bowl and set aside.
To finish up the chocolate batter, whisk the sugar into the melted chocolate. Add the eggs and mix well. Stir in the vanilla and last, stir in the flour until well combined.
Pour half of the chocolate batter into the greased baking pan. Dollop over half of the peanut butter mixture. Pour over the rest of the chocolate mixture and then finish dolloping over the peanut butter mixture. With a butter knife, cut through all of the layers and drag down one side of the pan. Continue this pattern along the whole pan, and then switch directions 90 degrees and drag the pattern across the batter the other direction.
Bake about 45 minutes, or until a toothpick inserted towards the side of the pan comes out rather clean with a few sticky crumbs inserted. (I learned its good to avoid testing baked goods for doneness in the middle - it's often a bit wet and the tasty treat will keep cooking for a bit once you take it out of the oven. Best to test about halfway between the edge of the pan and the center.)
Cool completely and then chill before cutting. With the parchment overhang, you can lift the brownies out really easily. If you chill completely, the cut brownies will have clean, nice edges. Good example. Hurried example.
A few things about this recipe...
The original recipe calls for powered sugar in the peanut butter mixture. I made a mistake and while I had even measured out the powered sugar, I ended up adding granulated sugar. I think this make for a plenty thick peanut butter layer that was very swirl-able. Something thicker would be really hard to swirl!
The double boiler method of melting the chocolate is fussy. Next time I make these, I will just melt the chocolate and butter in a saucepan over very low heat. I will use the saucepan as my mixing bowl and save a dish.
Turns out today is National Peanut Butter and Jelly day. Glad I could cover the PB at least!
