No-Bake Banana Cake: The Genius Way to Turn Old Cookies into a Showstopping Dessert

If you have a bag of stale or forgotten spiced cookies (like traditional gingerbread or pfeffernüsse) sitting in your pantry, don’t throw them out. This no-bake recipe revives them into a beautiful, layered icebox cake that tastes completely gourmet. By combining the spiced cookie crumbs with tangy cream and fresh fruit, you get a perfectly balanced dessert that tastes like a decadent trifle without any of the heavy kitchen labor.

Here’s what you need: 17 ounces (500g) of spiced cookies or gingerbread, 2 ½ cups (600ml) of high-fat Greek yogurt (10% fat) or sour cream, 1 ½ ripe bananas, and about 3 tablespoons of hot water to bind the crust.

To make it, line the bottom of a springform pan with parchment paper. Break up a handful of the cookies and pulse or crush them into fine crumbs — just enough to cover the bottom of your pan. Gradually add the hot water one tablespoon at a time, mashing it into the crumbs until the mixture becomes sticky enough to hold its shape, being careful not to make it too wet. Firmly press this damp cookie mixture into the bottom of the pan to create your crust.

Next, slice your bananas lengthwise and arrange them in a single layer flat-side down directly over the crust. Grind the remaining cookies into crumbs, setting aside 3 tablespoons of the dry crumbs to use later for the topping. Mix the rest of the cookie crumbs thoroughly with your high-fat yogurt or sour cream until completely smooth and combined.

Finally, spread this creamy cookie mixture evenly over the bananas, smooth the top with a spoon, and dust the surface with the reserved cookie crumbs. Pop the cake into the refrigerator for a full 24 hours to let the cookies absorb the moisture, transforming the whole thing into a perfectly sliceable, velvety dessert.
