    If you love Milo and chocolate... then you've come to the right place!!! This cheeky little slice combines both of those things into a decadent dessert! So if you've got a tin of Milo sitting in the cupboard (and you've been able to resist making 4 Ingredient Milo Weet-Bix Balls, Milo Biscuits, Oat & Milo Slice, Easy Milo Balls or Tim Tam & Milo Microwave Fudge) then you're all set to make this slice!

    Milo Mousse Chocolate Slice

    This slice has a chewy and dense chocolate base which is topped with an EPIC chocolate mousse layer! You're going to LOVE it!

    Ingredients

    For the base: 

    • butter
    • Milo (malted milk powder)
    • cocoa powder
    • caster sugar
    • vanilla
    • eggs
    • plain flour

    For the Milo mousse topping: 

    • dark chocolate
    • thickened cream for whipping (not low fat or light cream)
    • Milo (malted milk powder)
    • cocoa powder
    • caster sugar

    * Please scroll to the recipe card at the bottom for ingredient quantities and the method

    Egg-Free Chocolate Milo Mousse

    A classic chocolate mousse is made with eggs... but of course not everyone can eat mousse made with eggs (egg allergies, unable to eat raw egg due to pregnancy etc) and so this recipe is the perfect solution!

    Even though it's egg-free, it's still got that beautiful light and fluffy creamy chocolate mousse texture and you're going to LOVE it. It's perfect in this slice, but it also tastes AMAZING all on it's own.

    It's based on this original recipe by Twins and a Blog.

    Tips For Cutting The Slice

    When it comes to cutting slices into perfect little pieces, my OCD really comes out to shine! To cut this slice into pretty pieces, here's a few tips: 

    • wait until the mousse has set before cutting
    • use a really large flat knife
    • slowly and lightly press the knife down through the mousse layer and then press slightly harder when you feel the resistance from the chocolate base
    • wipe the knife clean between cuts
    • cut the slice into long bars before cutting into smaller pieces

    * For more tips on cutting slices, check out my entire post here!

    Notes

    Recipe Tips
    Malted milk powder - Milo is a brand of malted milk powder available in Australia. If you can't buy Milo, you can use any brand of malted milk powder you like. 
    Chewy and dense base - there’s no rising agent in the base because we’re aiming for a really dense, rich and chewy taste (the Milo is what gives it the yummy little chewiness!). 
    Mousse layer - this recipe makes quite a lot of mousse, so you might like to leave some of it off the slice (and keep it for a cheeky little snack on it's own). If you use all of the mousse, it will end up looking like the photos on this page (about 50% slice and 50% mousse). 
    Egg-free mousse - this is not a traditional mousse recipe as it's made without raw eggs. 
    Tips for cutting the slice - wait until the mousse has set before cutting it with a large flat knife. Press slowly and lightly down through the mousse layer and then press slightly harder when you feel the resistance from the chocolate base. Wipe the knife clean between cuts. Cut the slice into long bars before cutting into smaller pieces.
    Chilling time - chill the slice in the fridge for 5 hours or until the mousse has completely set. 
    Storing the slice - store in an airtight container in the fridge for up to 5 days.
