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.

5 ingredients9 steps


    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.

    I melt everything except krispies and chocolate together in microwave as it mixes better. I also melt the chocolate and some butter in the microwave to melt for the top.
