Peanut Butter Blondies

This soft and chewy Peanut Butter Blondies have a delicious peanut butter flavor and plenty of peanut butter chips. They’re made in 1 bowl with no mixer – and taste delicious with a cold glass of milk. These peanut butter blondies have all the flavor of your favorite peanut butter cookies in fudgy, chewy, cookie bar form. They’re like a brownie in texture, but ALL peanut butter in flavor – thanks to peanut butter in the batter and the fact that they’re filled with peanut butter chips.

Warning – these are for true peanut butter lovers only.

Peanut Butter Blondie Recipe

I originally posted this peanut butter blondie recipe waaaaaay back in 2015 (about a week after I first “launched” my blog). But I knew I could improve the recipe to:

• be chewier
• have a better balance of peanut butter flavor without being too rich
• and make a bigger batch

So it was time to get recipe testing.

Here’s the ingredients we ended up with:

• ⅔ cup unsalted butter
• 2 cups light brown sugar (or you could use 1 cup dark brown sugar and ¾ cup white sugar)
• ¾ cup peanut butter
• 3 large eggs
• 2 teaspoons vanilla extract
• 2 cups all-purpose flour
• ¼ teaspoon salt
• ¾ cup peanut butter chips
• ¾ cup chocolate chips

Compared to the original recipe, I wanted to ensure that they didn’t turn out greasy or too rich – so I changed up the ratio of butter and peanut butter. We’re using brown sugar to make the texture chewier (brown sugar has more moisture than white sugar), and 3 eggs create a slightly gooier consistency.

When adding in the flour, gently fold it into the batter using a rubber spatula or wooden spoon. Whevener you make brownies or blondies, it’s important to gently fold in the flour to minimize the formation of gluten. More gluten leads to a drier, cakier texture.

Then to keep our peanut butter blondies gooey and chewy without getting dry, be careful not to overbake. In my oven 30 minutes is tops. It tends to be that metal pans creat blondies with cruncher edges and bake a little faster than baking blondies in a glass or ceramic pan.

Looking for peanut butter blondies with peanut butter frosting? Use my peanut butter buttercream recipe to frost the cooled blondies. Warning – these will be very rich and extra peanut buttery.

These peanut butter blondies taste like thick, extra soft peanut butter cookies that have a delicious brownie-like texture. And since it makes an extra large batch – there’s enough for seconds.
