    What You Need

    Just 4 ingredients are needed to make our chocolate peanut butter slice!

    Please scroll to the recipe card at the bottom of the post for the ingredient quantities and the full detailed method.

    The ingredients for a peanut butter chocolate slice.
    • Rice Malt Syrup - use rice malt syrup or replace with honey if you prefer.
    • Rice Bubbles - or any puffed rice.
    • Peanut Butter - I recommend using store-bought creamy peanut butter (store-bought works better than homemade peanut butter in this recipe).
    • Chocolate - use milk or dark chocolate for melting over the top.
    • Optional - add a little coconut oil or vegetable oil to the chocolate when melting. This helps to stop the chocolate from cracking when cut.

    Step By Step Instructions

    It takes just 10 minutes to prepare our no bake Thermomix slice.

    Please scroll to the recipe card at the bottom of the post for the ingredient quantities and the full detailed method.

    Expert Tips

    Here's my top tips for making Thermomix chocolate peanut butter slice:

    • substitute the rice malt syrup for honey if you prefer
    • use creamy store-bought peanut butter (not homemade) for the best results
    • adding coconut oil/vegetable oil to the chocolate when melting, helps to stop the chocolate from cracking when cut.
    • chill in the fridge for 1 hour or until set.
    • store in an airtight container in the fridge for up to 1 week.
    • this slice needs to be kept in the fridge so that the rice bubble base stays crunchy.
    • freeze in an airtight container for up to 1 month.

    FAQs

    Can I make this using an older Thermomix model?

    Yes! This recipe is suitable for all models of the Thermomix.

    How do I make sure my slice base is crunchy?

    Firstly, ensure that you use a new (unopened) box of rice bubbles - older rice bubbles will taste stale and have lost their crunch.
    Secondly, ensure the slice is kept stored in the fridge.

      Has anyone tried this with organic brown ‘rice puffs’ rather than rice pops or rice bubbles? Did it work? TIA
