Peanut Butter Blondies with Chocolate Frosting

Oh, decadence.

That’s really all there is to say.

Also, this: Dense, peanutty-caramelly blondies, slicked with thick, creamy, indulgent chocolate frosting. Heaven.

Now that’s all.

From Joy the Baker
Makes about 40.

For the blondies:

10 T. unsalted butter, cut into 5 cubes
2 cups brown sugar
1 cup creamy peanut butter
2 eggs
2 tsp. vanilla extract
1/2 tsp. salt
2 cups flour
1 tsp. baking powder

Preheat oven to 325. Grease a 9×13-inch pan, then line the pan with parchment paper, then grease the paper. (No worries if you don’t have parchment paper. Just grease the pan.)

Melt butter and sugar together in a saucepan over medium heat just until the butter is melted. Remove from the heat and allow to cool for 5 minutes, then stir in the peanut butter. Allow the mixture to cool for 5 more minutes, then quickly stir in the eggs and vanilla extract.

Whisk together salt, flour and baking powder. Add the dry ingredients all at once to the peanut butter mixture and stir until just incorporated. Spread the batter, which will be thick, into the prepared pan and smooth over with a spatula. Bake for 20 – 25 minutes or until a toothpick inserted in the center of the blondies comes out clean. Allow blondies to cool to room temperature before frosting.

For the frosting:

6 T. unsalted butter, softened
3 T. unsweetened cocoa powder
1/4 tsp. salt
1 & 1/2 cups powdered sugar (and 1/2 cup more if needed)
3 T. milk
3/4 cup milk chocolate chips, melted*

*Melt the chips in a glass measuring cup in the microwave, stirring every 15 seconds.

Beat together the butter, cocoa, and salt with an electric mixer. Add 1/2 cup powdered sugar, then stir in 1 tablespoon of milk. Beat well. Add another cup powdered sugar, followed by 2 T. milk. Add the melted chocolate chips and beat to incorporate. If you need more thickness, add another 1/2 cup powdered sugar. Spread evenly over the cooled blondies, then cut into 40 pieces.

  1. Ok, so far on this blog you have made 4 recipes for blondies which makes me think you have a secret (or not so secret) passion for these delectable cookie bars! I tried a blondie recipe around christmas, and try as I may, I could not enjoy them. I think the recipe was a flop, and not that I can’t enjoy into a good blondie. So, my question, which recipe that you have posted here is the best?? Or, is your favorite recipe one you haven’t posted yet?

  2. You are right, Amanda, I do have a not-so-secret obsession with blondies! I’m not sure I really even realized it until I made the Best Blondies Ever last month and have been craving them since. And shame on me, I haven’t posted the recipe yet. But when I do, I will tell you, and you will have to try it, because I find it terribly sad that you have not developed your own secret passion for blondies.

  3. Yes! Please do share! 🙂 Also, adding to our list of things to do after your million guests leave: can we cook dinner again soon? Pretty please?
