Hip Hip Hooray! Hip Hip Hooray!

Price and I had a date night this past weekend!!!!!

Peanut Butter Swirl Brownies-1

Date nights are few and far between for us. Shoot- the last one was 2 months ago and before that was in the summer. We are busy and sorta lazy about it at the same time. Plus, there is the extra money involved when it comes to hiring a babysitter. But we bit the bullet and arranged for our lovely sitter to come over so we could get out.

We went out to dinner at Wagamama and had a great time together even though I wasn’t feeling great. Anyway, I love the food that they serve at Wagamama. It’s so, so fresh. And really flavorful. Plus, a few years ago the company I work for designed some of their US locations. So I got to see the designs develop, which is so much fun to see, and learn all about Wagamama. Like it’s super important to know that the red tile at the Faneuil Hall location is called Lipstick Red. ha!

Anyway, I always like to have special treats for our babysitter, who is our dog walker’s daughter. I sent out an email to her mom to ask what she wanted: Chocolate Chip Cookies or Peanut Butter Brownies. A bit later I got her sweet little response that it was a tough pick but she wanted the Peanut Butter Brownies. So I got to work looking for a knock your socks off recipe since she deserved it.

I think that this recipe fits the bill!

I adapted a Martha Stewart recipe to load it up with even more chocolate and peanut butter goodness. I just can’t leave well enough alone. But I think that more of awesome stuff is awesome.

The brownie is slightly cakey and so, so chocolatey. I don’t normally make brownies that are cakey, but I really enjoyed it. It had great flavor and structure. It certainly needed it as it was stuffed and topped with peanut butter. The swirl looks so nice too. Looks good, tastes good.

I added chocolate ships and peanut butter chips into the batter as well. I really wanted to over do it, but without over doing it. Get it. Good.

Peanut Butter Swirled Brownies

Makes an 8×8 pan


For the brownies

  • 8 tablespoons unsalted butter
  • 6 ounces semi-sweet chocolate chips
  • 2/3 Cup all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 2/3 Cup granulated sugar
  • 3 large eggs
  • 2 teaspoons pure vanilla extract
  • 1/2 Cup semi-sweet chocolate chips
  • 1/2 Cup peanut butter chips

For the peanut butter filling and topping

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


  1. Preheat oven to 325 degrees. Butter an 8-inch square baking pan and line with parchment, allowing a 2-inch overhang. Butter lining (not overhang).
  2. Make batter: Put butter and chocolates in a heatproof medium bowl set over a pan of simmering water; stir until melted. Let cool slightly. Whisk together flour, baking powder, and salt in a bowl.
  3. Whisk granulated sugar into chocolate mixture. Add eggs, and whisk until mixture is smooth. Stir in vanilla. Add flour mixture; stir until well incorporated.
  4. Make filling: Stir together butter, confectioners’ sugar, peanut butter, salt, and vanilla in a bowl until smooth.
  5. Pour one-third of batter into prepared pan; spread evenly with a rubber spatula. Drop dollops of peanut butter filling (about 1 tablespoon each) on top of batter, spacing about 1 inch apart. Drizzle remaining batter on top, and gently spread to fill pan. Drop dollops of remaining filling on top. Gently swirl peanut butter filling into batter with a butter knife, running the knife lengthwise and crosswise through layers.
  6. Bake until a cake tester inserted into brownies (avoid center and edges) comes out with a few crumbs but is not wet, about 45 minutes. Let cool slightly in pan, about 15 minutes. Lift out; let cool completely on a wire rack before cutting into squares. Brownies can be stored in an airtight container at room temperature up to 3 days.
