Peanut Butter Swirl Brownies

It has been about 10 months since Cheryl joined the IPC kitchen staff and it's been my joy to watch her grow in her culinary skills, especially in baking. She has taken the initiative to seek out recipes and be in charge of baking Wednesday noon service lunch desserts.

When I walked into the kitchen later than my usual time today, this is what I found. Most gorgeous peanut butter swirl brownies I have ever seen! I am just kicking myself that I wasn't there to take the prep photos to share with you.

But I know these finished photo shots will make you want to make these right now. And you should. It's wonderfully moist and yummy. You'll never go back to ol' regular brownies again.

Peanut Butter Swirl Brownies

For the Brownies

1¼ cups all-purpose flour(6.25 oz)
1 teaspoon salt
2 tablespoons dark unsweetened cocoa powder
11 ounces dark chocolate, coarsely chopped
1 cup (8 ounces) unsalted butter, cut into 1-inch pieces
1 teaspoon instant espresso powder
1½ cups granulated sugar (10.5 oz)
½ cup packed light brown sugar (3.5 oz)
5 eggs, at room temperature
2 teaspoons vanilla extract

For the Peanut Butter Swirl

½ cup (4 oz) unsalted butter, melted
1 cup powdered sugar (4 oz)
1½ cups creamy peanut butter (12 oz)
½ teaspoon salt
1 teaspoon vanilla extract

1. Preheat the oven to 350. Criss-cross two sheets of heavy duty aluminum foil and line 13x9x2 baking pan. Lightly spray with oil spray.

2. In a medium bowl, whisk together the flour, salt and cocoa powder. Set it aside.

3. Place the chocolate, butter, and espresso powder in a large heat-proof bowl. Set the bowl over the saucepan of simmering water. Stir the chocolate/butter mixture occasionally until completely melted and smooth. Turn off the heat, but keep the bowl over the water. Add the sugars and whisk until completely combined. Remove the bowl from the pan. The mixture should be room temperature.

4. Add eggs and vanilla extract to the chocolate mixture and whisk until just combined. Do not over mix.

5. Using a rubber spatula gently fold in flour/cocoa powder mixture into the chocolate until just combined. Pour the batter into the prepared baking pan. Use a spatula to smooth the top.

6. In a medium bowl, whisk together the peanut butter swirl ingredients. Using a spoon or a tablespoon scoop, drop dollops of the peanut butter mixture over the top of the brownie batter. Using a butter knife, swirl the peanut butter and chocolate together, running the knife through the two batters. Smooth the top.

7. Bake for 30 minutes in the center of the oven, rotating the pan halfway through the baking time, until a toothpick inserted in the center of the brownies comes out with a few moist crumbs sticking to it.

Let the brownies cool completely. Lift the brownies out of the pan using the foil handles. Cut into squares and serve.

Store at room temperature in an airtight container for up to 3 days.

Note: 12x24x2 steam pans can be used for large volume baking, double the recipe which yields 32 squares each pan.

  2. These look great! For some reason peanut butter and chocolate doesn't seem to be as popular a combination in the UK as it seems to be in the US, but I think it is time that changed! Thank you for sharing this and I hope you have a blessed day.

  11. As a caterer for my church in Oklahoma City, I deeply appreciate your blog! I have so many questions to ask you, but I will start with just one for now. Your desserts are always perfectly cut and with no rough or messy edges. I especially have a hard time with brownies. Do you have a tip you would share?


  12. Hi, Linda! So sorry for the delayed response! For the photos, I usually chill/almost freeze the dessert in the freezer, cut, then let thaw for the photos. Sometimes, it doesn't work out the way I plan and can see the hardened butter... :)
