Essential Ingredients
Here’s what you’ll need to make this delicious dish:
-
All-Purpose Flour: Essential for structure; sifted flour helps create light and tender brownies.
-
Cocoa Powder: Choose unsweetened cocoa for deep chocolate flavor without extra sugar.
-
Granulated Sugar: Sweetness is crucial; adjust based on your taste preferences.
-
Brown Sugar: Adds moisture and caramel notes; use light or dark based on desired richness.

Butter: Use unsalted butter for control over saltiness; melted butter creates a fudgier texture.
-
Eggs: Eggs bind everything together; use room temperature eggs for better mixing.
-
Peanut Butter: Creamy or crunchy – your choice! Natural varieties enhance flavor without added sugars.
-
Vanilla Extract: A splash enhances all flavors; always opt for pure vanilla if possible.

Let’s Make it Together
Preheat your oven to 350°F (175°C). Grab an 8×8-inch baking pan and line it with parchment paper for easy removal later.
Melt the Butter and Mix Sugars: In a medium saucepan over low heat, melt the unsalted butter gently until just liquid. Stir in granulated sugar and brown sugar until fully combined.
Add Eggs and Vanilla: Remove the pan from heat and let it cool slightly before whisking in the eggs one at a time along with vanilla extract until smooth.
Sift Dry Ingredients: In a separate bowl, sift together flour, cocoa powder, baking powder, and salt. This step ensures no lumps remain and promotes even mixing.
Add Peanut Butter: Fold in creamy peanut butter until well incorporated into the mixture. This is where magic happens – chocolate meets nutty goodness!
Bake: Pour the brownie batter into your prepared pan and spread it evenly using a spatula. Bake in preheated oven for about 20-25 minutes until set but still soft in the center.
Enjoy these decadent peanut butter brownies warm or cooled down with a scoop of ice cream on top! Each bite will transport you back to those carefree days filled with laughter and sweet treats shared among friends.
