Description

These peanut butter brownies are a deliciously rich and moist treat made with creamy peanut butter and a perfect blend of sugars, butter, and vanilla. They bake up with a soft, slightly chewy texture and a delightful peanut buttery flavor, perfect for serving warm with ice cream or enjoying as an indulgent snack.


Ingredients

Wet Ingredients

  • 1 cup creamy peanut butter
  • 11 tablespoons unsalted butter, softened
  • 2 teaspoons vanilla extract
  • 4 large eggs

Dry Ingredients

  • 1 cup light brown sugar, packed
  • 1 ⅓ cups white granulated sugar
  • 2 teaspoons baking powder
  • 1 teaspoon salt
  • 2 cups all-purpose flour


Instructions

  1. Preheat the oven. Set your oven to 325°F (163°C) and grease a 9×13 inch baking pan thoroughly to prevent sticking.
  2. Cream the wet ingredients. In a large mixing bowl or with a stand mixer, combine the creamy peanut butter, softened unsalted butter, light brown sugar, white granulated sugar, and vanilla extract. Beat together until the mixture is smooth and creamy.
  3. Add eggs. Incorporate the large eggs into the creamed mixture one at a time, beating well after each addition to ensure they are fully mixed in.
  4. Mix dry ingredients. Add the baking powder, salt, and all-purpose flour to the wet mixture. Stir or mix on low speed until just combined and the batter is smooth without overmixing.
  5. Pour and bake. Transfer the batter evenly into the prepared 9×13 inch pan and spread it out smoothly. Bake in the preheated oven for 40 to 45 minutes, or until the top is set and springs back lightly when touched.
  6. Cool and serve. Allow the brownies to cool in the pan before cutting into 16 squares. Serve as is or with a scoop of ice cream for an extra indulgent dessert.

Notes

  • Ensure the butter is softened to room temperature for easier mixing and a smoother batter.
  • Do not overbake the brownies to keep them moist and fudgy rather than dry and cakey.
  • Use a toothpick inserted into the center to check doneness; it should come out with a few moist crumbs but not wet batter.
  • Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
  • For an extra peanut flavor, swirl in some additional peanut butter on top before baking.
