Ingredients
You only need:
- 1 cup creamy peanut butter
- 1 cup packed brown sugar
- 2 large eggs
Regular creamy peanut butter gives the most reliable texture. If using natural peanut butter, make sure it is well mixed before adding it to the batter.
How to Make 3-Ingredient Peanut Butter Blondies
Start by preheating the oven to 350°F. Lightly grease an 8-inch baking dish or line it with parchment paper.
In a medium bowl, combine the peanut butter, brown sugar, and eggs. Stir until the mixture becomes smooth, thick, and completely combined.
Spread the batter evenly into the prepared baking dish and smooth the surface with a spatula.
Bake for approximately 20 to 25 minutes, until the top is lightly golden and the center is just set. For softer, fudgier blondies, avoid overbaking.
Allow the blondies to cool for at least 20 minutes before slicing them into squares.
Tips for the Best Peanut Butter Blondies
Don’t Overbake
The center should be just set when you remove the pan from the oven. Baking too long can make the blondies firmer and less chewy.
Let Them Cool Before Slicing
Allowing the blondies to cool helps them firm up and makes cutting much easier. For particularly clean slices, you can briefly chill the pan before cutting.
Use Creamy Peanut Butter
Regular creamy peanut butter works best for this simple recipe. Very oily or separated natural peanut butter may affect the final texture.
Easy Variations
Although the basic recipe uses only three ingredients, you can add a few extras if desired.
Chocolate chips: Fold a handful into the batter for a peanut butter-and-chocolate combination.
Chopped peanuts: Add chopped peanuts for extra crunch.
Sea salt: A small sprinkle of sea salt on top creates a nice contrast with the sweet brown sugar.
How to Serve Peanut Butter Blondies
These blondies are delicious served slightly warm or completely cooled. Because they are rich, cutting them into small squares works especially well.
Serve them with:
- Cold milk
- Coffee
- Hot tea
- Vanilla ice cream
- Fresh strawberries
For an easy dessert, warm a blondie slightly and add a scoop of vanilla ice cream on top.
