Quick and easy, Mocha Squares have a chocolate oat base with coffee icing. Teatime or coffee break favourite.
This is another of my mother's recipes that I've made for years, although not so much recently - so I was pleased to re-discover it.
All the traybakes I mention below are great for feeding crowds, e.g. if you're making something to cater for an event. They're also an easy way to provide something sweet for a party or family gathering - much less fiddly than icing individual cakes if you're in a hurry.
Cocoa vs Drinking Chocolate
The base of the Mocha Squares are made in a similar way to Flapjack, but with a lot of cocoa to give a good chocolate flavour. When you're making chocolate cakes, traybakes or biscuits, you need to make sure you use what the recipe calls for.
Drinking chocolate is cocoa with added sugar and usually milk powder, so the chocolate flavour is diluted and sweetened. Fine for a drink, but no good for baking. I use Green & Black's as a good quality cocoa, but not the most expensive, and you get a good chocolate flavour.
If I'm using a brand that doesn't seem as strong, I might add extra cocoa and correspondingly less flour. Of course, you can adjust your proportions yourself if you have a preference for more or less of a chocolate flavour.
Helpful Tools
- Magic liner – Cut to fit the traybake tins and roasting tins you use most. You wash it every time. Nothing sticks and it doesn’t need greasing

Do you mean prepared (i.e. liquid) instant coffee or instant coffee granules or powder?
Susie Collings says
Hi Helen, Powder or granules - I've updated the recipe to be clear. Thanks 🙂
Chauntelle says
Looking forward to trying this recipe, can I use a coffee espresso rather than instant coffee?
Susie Collings says
Hi Chauntelle, If your espresso is strong it's probably fine. I would use 3 tablespoons which is 45ml. Cheers - Susie
Chauntelle says
Finally got around to trying this with an espresso and everyone’s loved them! Great recipe, thanks.
Judy says
Hi, should this spring back like a sponge when its cooked?
Susie Collings says
Hi Judy. This is a more biscuits base so it won't spring up like a sponge. Cheers- Susie
