    It's no secret that we LOVE making slices in our Thermomixes... especially easy no-bake slices!

    Let's get started....

    Why You're Going To Love This Recipe

    What's not to love about a simple Thermomix chocolate slice!?

    • No-Bake - there's no need to turn the oven on with this easy no bake slice. Simply melt, mix and chill!
    • Basic Ingredients - our slice is made using pantry and fridge staples, making it a budget friendly option.
    • Perfect For Lunch Boxes - the kids absolutely LOVE our chocolate slice recipe. Pop a piece into school lunchboxes for the yummiest treat.

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

    The ingredients for chocolate slice.
    • Biscuits - choose plain, sweet biscuits such as Arnotts Marie
    • Sweetened Condensed Milk - use full fat (not skim) sweetened condensed milk as it sets firmer
    • Butter - salted or unsalted butter is fine to use
    • Cocoa Powder - use regular unsweetened cocoa powder
    • Coconut - use shredded or desiccated coconut
    • Milk Chocolate - for melting over the top
    • Coconut oil - or vegetable oil. This helps to stop the chocolate from cracking when cut.
    • Sprinkles or 100s and 1000s - to decorate.
