Brew two shots of espresso or very strong coffee and let it cool slightly before using. The coffee should still be warm enough to soak into the ladyfingers easily, but not piping hot. Warm espresso gives the tiramisu its deep, rich coffee flavor while helping the cookies soften evenly without instantly turning mushy.
Pour the espresso into a shallow bowl or wide cup to make dipping easier. Quickly dip five ladyfingers into the coffee one at a time, turning them briefly so both sides absorb some flavor. Avoid soaking them for more than a second or two because they soften very fast and can fall apart if oversaturated. Arrange the dipped ladyfingers in a single layer at the bottom of a small baking dish or container, pressing them gently together so they form an even base.
Add the cottage cheese, sugar-free vanilla pudding mix, and almond milk to a blender or food processor. Start blending on medium speed until the mixture becomes smooth and creamy. Slowly add the almond milk a little at a time instead of pouring it all in at once because the consistency can thin out quickly. Blend until the filling looks silky and spreadable with no visible cottage cheese curds remaining. The pudding mix will continue thickening the filling as it chills, so it’s better to keep the mixture slightly thicker than too thin.
Spoon about half of the blended cottage cheese mixture over the first layer of espresso-soaked ladyfingers. Use a spatula or the back of a spoon to spread the filling evenly all the way to the edges of the dish. Take your time smoothing the layer so every bite has a balanced amount of creamy filling and coffee-soaked cookies.
Dip the remaining five ladyfingers into the espresso using the same quick-dip method, then carefully arrange them over the cream layer to create the second layer of the tiramisu. Try to line them up evenly so the dessert slices more neatly once chilled.
Spread the remaining cottage cheese mixture evenly over the top layer of ladyfingers, smoothing the surface carefully with a spatula for a clean bakery-style finish. Make sure the top is level so the cocoa powder dusting looks even and beautiful once added.
Place a fine mesh sieve over the dish and dust the top generously with cocoa powder. Sifting the cocoa helps create a soft, even layer without clumps and gives the tiramisu that classic rich coffeehouse appearance. You can add a little extra cocoa powder if you prefer a deeper chocolate flavor.
Cover the dish tightly with plastic wrap or a lid and refrigerate for at least 4 hours, although overnight is even better. During this time, the ladyfingers soften into cake-like layers, the espresso flavor deepens, and the creamy filling thickens into a rich, luxurious texture. Serve chilled straight from the refrigerator for the best flavor and consistency.
