No-Bake Mocha Fudge Squares
Coffee and chocolate belong together, especially when you don’t want to turn on the oven. These squares set up firm enough to cut clean but stay creamy when you bite in.
No tempering chocolate or worrying about oven temperatures. Just melt, mix, and wait.
Why Instant Coffee Works Better
Skip the brewed coffee here. Instant coffee or espresso powder gives you pure coffee flavor without adding liquid that would make your fudge too soft. Dissolve it completely in the vanilla extract first so you don’t get bitter granules in the finished squares.

Melt Chocolate Low and Slow
Use a double boiler or microwave in 30-second bursts. Overheated chocolate seizes up and turns grainy – there’s no fixing that. Stir constantly and remove from heat while a few small pieces remain. They’ll melt from residual heat.
Press Firmly Into Pan
Line your pan with parchment that hangs over the edges. Press the mixture down hard with a spatula or your hands. Air pockets make the squares crumbly instead of fudgy. The surface should look smooth and even.
Getting Clean Square Cuts
- Warm your knife under hot water and dry it between cuts for cleaner edges that don’t drag.
- Make these a day ahead – they actually taste better after the flavors meld overnight in the fridge.
Frequently Asked Questions
Will milk chocolate work instead of dark?
Yes, but reduce the sweetened condensed milk to 3/4 can since milk chocolate is already sweeter than dark chocolate.
How long do these keep at room temperature?
They’ll stay firm for about 2 hours at room temperature, then start getting soft. Store them in the fridge.
What if my mixture seems too thick to spread?
Let it cool for 5 minutes, then add 1 tablespoon of heavy cream and stir until it reaches spreading consistency.
