Let me take you through these incredible layers…

We start off with a blondie layer that is so deliciously thick and fudgy, and is loaded with peanut butter flavour. They’re perfect on their own, but today I’m taking them over-the-top good.

I’ve topped these blondies off with a layer of creamy chocolate that is stuffed full of salted peanuts. Because who doesn’t love the combination of sweet and salty? Peanut butter and chocolate?

These bars are a peanut butter lover’s dream!

Deliciously fudgy blondies loaded with peanut butter, and topped with a salted peanut chocolate layer!
For the Blondies
  • 3/4 cup unsalted butter 170g, melted
  • 1 cup light or dark brown sugar 200g
  • 1/2 cup caster/granulated sugar 100g
  • 1 large egg + 1 large egg yolk
  • 1/2 cup smooth peanut butter 125g
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 1 and 1/2 cups plain/all-purpose flour 190g
For the Topping
  • 1 and 1/2 cups chocolate chips 265g
  • 1/4 cup smooth peanut butter 65g
  • 1 cup salted peanuts 125g, chopped
For the Blondies
  1. Preheat the oven to 180C/350F/Gas 4. Line an 8x8-inch baking pan with aluminium foil and spray with baking spray. Set aside.
  2. Whisk together the butter and sugars until smooth and combined. Add the egg, egg yolk, peanut butter, vanilla, and salt, and whisk until smooth and combined. Fold in the flour until completely combined. The mixture will be quite thick.

  3. Spread the batter evenly into the prepared pan, and bake for about 25 - 30 minutes, or until the centre is no longer jiggly and a toothpick inserted comes out clean. Do not over-bake. Allow to cool completely in the pan on a wire rack before topping - about 2 hours.

For the Topping
  1. In a microwave-safe bowl, add the chocolate chips and peanut butter. Heat in 30 second intervals, stirring after each one, until melted and smooth. Fold in the chopped peanuts.

  2. Spread the melted chocolate over the top of the blondies, sprinkle with extra chopped peanuts if desired, and allow to set in the fridge before slicing into bars - about 1 hour.


Blondies can be stored in an airtight container at room temperature or in the fridge for up to 1 week. They also freeze well for up to 3 months. Thaw overnight before serving.
