Soft and gooey Brown Butter Glazed Peanut Butter Blondies. Made with butter, creamy peanut butter, brown sugar, vanilla, and even some chocolate – if you’d like that too. These bars are generously glazed with a sweet, thick, and creamy brown butter maple glaze. There’s really nothing not to love about these peanut butter blondies. And the true secret? Brown butter and brown sugar. They keep these blondies incredibly flavorful, soft, gooey, and so delicious. They’re sweet, salty, peanutty, made in just 40 minutes, and every last bite is truly delicious.

I know you all know this by now, but peanut butter has always been an ingredient my family loves. Growing up in Ohio, the buckeye state, my mom would often make buckeyes. Also known as chocolate peanut butter balls. And her Special K-Bars (the third recipe I ever posted) well, those were in our weekly rotation. Sometimes two, even three times a week – depending on the week!

My mom kept the desserts very well stocked.

So, yes, peanut butter has always been a staple dessert ingredient. And I love to play around with new ways to incorporate it into recipes, both sweet and savory.

Since we’re in this weird time where we’re transitioning from winter to spring. Lately, I’ve mostly been experimenting with mixing lighter berry-filled sweets with the tried and true classics.

However, it’s been forever since I made blondies, so I thought it would be fun to reinvent them a bit.

Enter these extra peanutty, sweet, and salty blondies. They’re the easiest to make and so delicious. Perfect for the weekend!

The steps

What I love about this blondie recipe is just how simple it is. You don’t even need a mixer!

Melt the butter and peanut butter together until creamy and combined. Add the brown sugar, eggs, and vanilla. Then stir in the flour with some baking powder and a pinch of salt.

Very simple.

Since we all love chocolate, I stirred in a handful of chocolate chunks before baking. Totally optional.

While the bars cool, make the glaze.

Most blondie recipes are not glazed, but I wanted these to be extra special and a little over the top.

I took inspiration from my apple doughnuts that I shared this past fall. I decided on a buttery maple glaze with vanilla throughout. It’s just browned butter, maple syrup, powdered sugar, vanilla, and salt. Simple, but delicious.

And it really does make these bars.

I kept the glaze drizzly but still thick and creamy. That way it can really sink into all the nooks and crannies of these peanutty blondie bars.

Nothing fancy by any means, but total and complete perfection.

Here’s a little tip, let the bars cool for 10 or so minutes, then drizzle on the glaze and enjoy a few of the bars warm. There isn’t anything better. The glaze melts onto the chocolate chunks and pockets of peanut butter. Every bite is so delicious!

Ingredients

Brown Butter Glaze

Instructions

  • 1. Preheat the oven to 350° F. Line a 9×13 inch baking dish with parchment paper.
    2. In a microwave-safe bowl, melt together the butter and 1/2 cup peanut butter, stirring every 30 seconds until melted. Stir in the brown sugar, sugar, eggs, and vanilla. Add the flour, baking powder, and salt. Stir in the chocolate, if using.
    3. Press/spread the dough out into the prepared dish. Bake for 18-22 minutes, until just set in the center. Let cool.
    4. Meanwhile, make the glaze. Add the butter to a small pot set over medium heat. Allow the butter to brown lightly until it smells toasted, about 2-3 minutes. Remove from the heat and whisk in the maple syrup, powdered sugar, and vanilla. Drizzle the glaze over the bars. Let set for 5 minutes. Cut into bars…snack and enjoy!

Notes

Storing: these bars keep well for 3-4 days at room temperature or in the fridge. 
To cool the bars quickly for frosting: place in the freezer for 15 minutes. Remove and glaze.

    Very good! I added some flaky salt to the top because they were very sweet. Also I would half the icing next time. But I loved the texture of the blondie. 🙂

    Made these for a dinner party and everyone was raving! Had quite a bit of extra glaze – I think you could cut that in half if you want!

    Honestly: so. very. good! I’ve made these twice now, in as many weeks. 🙂 I added some flavored nut butters – a macadamia/coconut, and a pecan/caramel – and they worked beautifully. Based on personal sweetness preference, I drizzled on just a portion the glaze, and refrigerated what was left; saved well, and worked perfectly again today after a quick warming in the microwave. Next week’s flavor… Cinnamon Bun!

    1. Hey Sharon,
