3-Ingredient Peanut Butter Blondies

Step 4: Transfer the Batter to the Pan

Pour the batter into your prepared baking pan.

Because the mixture is quite thick, use a spatula or the back of a spoon to spread it evenly into the corners.

Try to create a level surface so the blondies bake uniformly.

Step 5: Bake

Place the pan in the preheated oven and bake for approximately 20–25 minutes.

The exact baking time can vary depending on your oven and the size of your pan.

Look for edges that appear set and a center that is cooked but still slightly soft. A toothpick inserted near the center should come out with a few moist crumbs rather than completely wet batter.

Be careful not to overbake them. Peanut butter blondies can quickly go from soft and chewy to firm and dry if left in the oven too long.

Step 6: Cool Completely

Remove the pan from the oven and place it on a cooling rack.

Allow the blondies to cool in the pan before slicing. This is especially important because the center continues to set as it cools.

For the cleanest cuts and a particularly chewy texture, you can allow them to cool completely before removing them from the pan.

Step 7: Slice and Serve

Once cooled, use the parchment overhang to lift the blondie slab from the pan.

Place it on a cutting board and slice into squares or rectangles.

For neat edges, use a sharp knife and wipe it clean between cuts.

Tips for the Best Blondies

Don’t Overbake

This is probably the most important tip. The blondies should look set around the edges but retain some softness in the middle when they come out of the oven.

They will firm up as they cool.

Measure Carefully

With only three ingredients, each one plays an important role. Accurate measurements help ensure the right consistency.

Use a Consistent Peanut Butter

A standard creamy peanut butter tends to produce predictable results. If using natural peanut butter, make sure the oil and solids are thoroughly mixed together first.

Let Them Cool

It can be tempting to cut into the blondies immediately, but allowing them to cool gives the structure time to develop. You’ll get much cleaner slices and a better texture.

Easy Ways to Customize Them

Although the basic recipe needs only three ingredients, you can add optional extras if you want to experiment.

Try folding in:

• Chocolate chips
• Chopped roasted peanuts
• Mini chocolate candies
• A small handful of shredded coconut
• Chopped dark chocolate

You can also sprinkle a few chocolate chips or chopped peanuts over the batter before baking for an attractive finish.

If you’re adding extras, don’t overload the batter. The simple peanut butter flavor is part of what makes these blondies so enjoyable.

How to Store Peanut Butter Blondies

Store completely cooled blondies in an airtight container at room temperature for several days.

For longer storage, place them in a sealed container in the refrigerator. Let them sit at room temperature briefly before serving if you prefer a softer texture.

They can also be frozen. Wrap individual portions well and place them in a freezer-safe container or bag. Thaw them at room temperature before enjoying.

What to Serve With Them

These blondies are delicious on their own, but they can also become part of a more indulgent dessert.

Serve a square with:

• A glass of cold milk
• A cup of coffee
• A scoop of vanilla ice cream
• Fresh berries
• A drizzle of melted chocolate

For a simple dessert presentation, warm a blondie slightly and serve it with vanilla ice cream.

Common Questions

Can I use crunchy peanut butter?

Yes. Crunchy peanut butter works well if you enjoy bits of peanuts throughout your blondies.

Why are my blondies dry?

The most common reason is overbaking. Because the batter is simple and doesn’t contain flour, the texture can change quickly toward the end of baking. Remove the blondies once the edges are set and the center is just cooked.

Can I make them thicker?

Yes, but a smaller pan will increase the thickness and may require additional baking time. Keep an eye on the center rather than relying only on the clock.

Should I refrigerate them?

You don’t have to if you’re eating them within a few days and storing them properly in an airtight container. Refrigeration is useful if you want to extend their storage time.

Final Thoughts
