About the bake

There is something so simple but indulgent about a Rice Krispie Squares. A family friendly recipe that you can bake along with the kids, but this recipe has more of an adult twist to it with a cheeky layer of Proper Nutty peanut butter and topped with rich chocolate.

130Prep Time


  1. Step 1:

    Prepare a square baking tin by lining it with greaseproof paper.

  2. Step 2:

    Measure the Rice Krispie out into a large bowl and keep to one side.

  3. Step 3:

    In a heatproof bowl melt the butter and pour in with the Rice Krispies.

  4. Step 4:

    If using large marshmallows chop in half using scissors or tear with your hands and place in a microwavable bowl with 2-3 tbsp of water and microwave for 2 minutes, in 30 seconds bursts, stir between each one. Alternatively, you could melt in a saucepan on a medium heat over a hob.

  5. Step 5:

    Pour the melted marshmallow into the Rice Krispies bowl, using a spatula to clear any excess off the sides. Mix all the ingredients together until fully combined.

  6. Step 6:

    Pour the mixture into the lined square baking tin and use the spatula to smooth down the top. Place in the fridge to chill for 30-40 minutes to set.

  7. Step 7:

    Once they have set, spread a layer of peanut butter on the top and leave to one side. 

  8. Step 8:

    Melt the chocolate in a heatproof bowl and pour over the top of the peanut butter and leave to cool before moving to the fridge to set. 

  9. Step 9:

    To achieve a smooth finish when slicing the krispie squares, heat the knife under warm water before cutting.
