Right now I’m in Hawaii, laying on a beach. Or perhaps I’m snorkeling with sea turtles. Or taking my first surfing lesson. Be jealous, be very jealous.

Even though I’m away, I couldn’t wait to share this recipe with you. Because it can’t wait, because it’s that good. I have been in a peanut butter mood lately (remember the Flourless Peanut Butter Cookies from last week?). I’ve gone through two jars of the stuff in under a month. Send help, or at least a tall glass of milk.

This recipe comes straight from Joy the Baker’s genius and it’s something that everyone must bake and enjoy themselves. Chocolate and peanut butter go together like, well, chocolate and peanut butter. It’s a combination that cannot be beat.

These blondies are a simple, no-fuss dessert, sure to please just about everyone. Just make sure you have a glass of milk nearby, you’ll need it to wash them down.

10 tablespoons unsalted butter, cubed
2 cups brown sugar
1 cup peanut butter, smooth or crunchy
2 eggs
2 teaspoons vanilla extract
1/2 teaspoon salt
2 cups flour
1 teaspoon baking powder

Preheat oven to 325 degrees F. Line a 9×13 inch baking pan with parchment paper or grease with butter.

Melt the butter and sugar together in a medium saucepan over medium heat. Once melted, remove from heat and allow to cool for 5 minutes. Stir in the peanut butter until combined. Add the eggs one at a time, and then the vanilla, stirring until combined.

In a separate bowl, combine the flour, baking powder, and salt. Add to the wet ingredients and stir until combined. Spread the batter into the prepared baking sheet. Bake for 30-40 minutes, until a toothpick inserted into the center comes out clean.

Let cool completely before frosting.

Milk Chocolate Buttercream

6 tablespoons unsalted butter, at room temperature
3 tablespoons unsweetened cocoa powder
1/4 teaspoon salt
2 cups powdered sugar
3-4 tablespoons milk
3/4 cup milk chocolate chips, melted

Combine all ingredients in the bowl of a stand mixer fitted with a paddle attachment. Beat on medium speed until smooth.

  15. alaa shafei says:

    I just made it by following ur recipe, but I faced a problem:s after I left the sugar and butter to cool down for 5 mins, the sugar became so stiff, then it melted again in the oven! I took it out of the oven but it is still soft but not wet, should I put it in the fridge before serving it?
