Why You'll Love These Blondies
The biggest attraction of this recipe is its simplicity. You don't need a mixer, multiple bowls, or a pantry full of ingredients. Everything comes together quickly in one bowl.
The finished blondies have a satisfying combination of slightly crisp edges and a soft, chewy center. Their peanut butter flavor is prominent without being overwhelming, making them delicious on their own or alongside a glass of cold milk, coffee, or tea.
They're also easy to customize. Once you've mastered the basic three-ingredient version, you can add chocolate chips, chopped peanuts, or a small sprinkle of sea salt if you want to experiment.
Ingredients
For a simple batch of peanut butter blondies, you'll need:
1 cup creamy peanut butter
1 cup brown sugar
1 large egg
Choose a smooth peanut butter for the easiest mixing and most consistent texture. Conventional creamy peanut butter generally works particularly well for this recipe.
Step-by-Step Method
1. Prepare the Oven
Begin by preheating your oven to 350°F (175°C).
Grease an 8-inch square baking pan lightly, then line it with parchment paper if desired. Leave a little parchment hanging over two sides of the pan. This will make it much easier to lift the blondies out after baking.
2. Combine the Peanut Butter and Brown Sugar
Add the peanut butter and brown sugar to a medium mixing bowl.
Using a sturdy spoon or spatula, mix them together until the sugar is evenly incorporated and the mixture looks thick and creamy.
Take a moment to scrape the sides and bottom of the bowl so there are no pockets of dry sugar remaining.
