This Coffee Slice is the perfect no-bake, sweet treat match for your next cup of coffee! A melt and mix coffee and biscuit base with chocolate and coffee icing, then set in the fridge.

Calling all coffee lovers out there, this one is for you! My Coffee Slice is another of my super easy no-bake slice recipes. With no cooking required, it sets in the refrigerator - now that's my kind of cooking!

It's got a rich, coffee flavoured biscuit base that's topped off with a coffee-spiked chocolate icing. You could probably describe this as a mocha slice, with that chocolate/coffee combo going on.

Ingredients you will need for this recipe

plain biscuits (I used Arnott's Marie)
salted butter
instant coffee
cocoa powder
light brown sugar
condensed milk
desiccated coconut
vanilla
milk chocolate
boiling water

*Please see the recipe card below for exact quantities and detailed instructions

How to make this recipe

Process the biscuits in a food processor until fine crumbs.
In a small bowl, mix the instant coffee, cocoa powder and light brown sugar with boiling water to dissolve.
Place crushed biscuits, condensed milk, coconut, melted butter, vanilla and coffee/cocoa mixture in a large bowl and mix well.
Press mixture into a greased and lined baking tin.
For the icing, melt the chocolate and butter together in the microwave, then add more instant coffee and mix.
Spread chocolate over biscuit base and place in the fridge to set.

My top tips for making this recipe

If you don't have a food processor, just put the biscuits in a sturdy plastic bag and give them a bash with a rolling pin or something else heavy.
Greasing and lining the baking tin is important, even though we aren't going to "bake" anything! This step will help you get your slice out of the tin once it's set. If it still won't budge, just sit the bottom of the tin in some hot water for a few seconds and it should come right out.

Serving suggestions and ideas for add-ins

I have just used plain-common-all-garden coffee in the recipe, but a flavoured coffee that you enjoy would be good too.
You could add some chopped walnuts.
Serve it with...a cup of coffee!
