How to Make No Bake Coffee Tart – Step-by-Step

1. Make the Crust
Start by preparing the crust, which gives this cake its deliciously crunchy foundation. Finely crush the cocoa cookies and transfer them to a large bowl. Meanwhile, melt the butter—either in the microwave or in a saucepan—and pour it over the crushed cookies (1). Add the instant coffee powder directly to the mixture, then stir well until everything is fully combined and evenly moistened.
To shape the base, line a 22 cm (9-inch) tart pan with parchment paper and grease the edge with a little butter (2). This step is optional but makes it much easier to remove the cake later. Pour the cookie mixture into the pan and use the back of a spoon to firmly press it down, spreading it across the base and slightly up the sides to form a shell. Once the crust is shaped, place it in the fridge to chill while you move on to the filling (3).
2. Make the Coffee Cream
Now it’s time to make the creamy coffee layer. Brew about four shots of espresso, sweeten them to taste if you like, and let the coffee cool completely in the refrigerator. Meanwhile, place the gelatin sheet in a bowl of cold water and leave it to soak until soft (4).
In a mixing bowl, add the mascarpone and whip it briefly with a whisk or electric beaters to loosen it up. Then pour in the cold espresso and mix until smooth (5). Once softened, squeeze out the excess water and gently melt the gelatin, either in a small pan over low heat or in the microwave (6).
Take a spoonful of the mascarpone cream and stir it into the melted gelatin (7). This little trick helps prevent lumps. Once smooth, incorporate the tempered gelatin back into the main bowl of cream, mixing gently until well combined (8).
In a separate bowl, whip the chilled heavy cream together with the powdered sugar until you get stiff peaks. Gently fold the whipped cream into the mascarpone and coffee mixture using a spatula, working slowly from the bottom up to keep the texture airy (9).
3. Combine and Chill
Take the crust out of the fridge and pour the coffee cream filling on top (10). Use a spoon or spatula to level the surface evenly. Return the cake to the fridge and let it rest for at least three hours, or until it’s firm and fully set. Just before serving, dust the top with a generous layer of unsweetened cocoa powder (11). For more sweetness you can also sprinkle with a little granulated sugar like I did, if you like.
And that’s it—your no bake coffee cake is ready to impress. Cool, creamy, and bursting with espresso flavor, it’s the perfect dessert to keep your kitchen (and your nerves) calm on a hot day.
Tips for Perfect Results
- Always temper the gelatin by mixing with a bit of cream first.
- Chill the crust while working on the cream for best structure.
- Don’t over-whip the cream or it may become grainy.
Variations You Can Try
One of the best things about this no bake coffee cake is how easy it is to adapt to your taste—or to what you have in the pantry. Once you’ve mastered the basic version, you can have fun playing around with different crusts, flavors, and toppings. Whether you want to make it more indulgent, add a boozy twist, or simply switch things up for a special occasion, here are a few delicious ideas to inspire you:
- Use vanilla cookies or Biscoff for the base.
- Add a shot of coffee liqueur for a grown-up twist.
- Layer with chocolate ganache or chocolate chips for more richness.
Storage Tips
Store the coffee cake covered in the fridge for up to 3 days. It isn’t suitable for freezing due to mascarpone texture.
