Layer this 1 creamy mixture over mixed berries for a low carb february dessert that doesn’t feel like a shortcut

Chill to set the flavors: Cover the casserole dish tightly with plastic wrap or a lid and refrigerate for at least 2 hours, or up to overnight. This resting time allows the flavors of the espresso and mascarpone to develop and the cream to firm up slightly, so each spoonful feels luxurious rather than loose.
Finish and serve: Just before serving, if using, sift the cocoa powder evenly over the top of the chilled cream layer for a nod to traditional tiramisu. Scatter the extra mixed berries over the surface for color and freshness. Use a large spoon to scoop out parfait-style portions, making sure each serving includes both creamy tiramisu layer and berries from the bottom.
Variations & Tips
For a slightly more classic tiramisu feel while keeping carbs low, you can tuck a thin layer of almond flour or finely ground nut “crumbs” (lightly toasted and unsweetened) between the berries and cream to mimic the softness of soaked ladyfingers without the sugar and starch. If you prefer a stronger coffee note, brush the berries lightly with an extra tablespoon or two of cooled espresso before adding the cream, or stir in a pinch of instant espresso powder to the mascarpone mixture. For a boozy version, add 1–2 tablespoons of coffee liqueur or dark rum to the mascarpone base, reducing the espresso slightly so the mixture doesn’t get too loose. To adjust sweetness, taste the mascarpone mixture before folding in the whipped cream and add another tablespoon or two of powdered sweetener if needed—berries vary in tartness. You can also swap the mixed berries for all raspberries or all strawberries if that’s what you have on hand, or use frozen berries that have been fully thawed and well-drained (keep in mind they’ll release more juice, giving you a saucier base). For dairy-sensitive guests, a very rich coconut cream can stand in for the whipped cream and a thick dairy-free cream cheese substitute can replace the mascarpone, though the flavor will lean less traditional. Finally, if you want individual portions instead of one casserole, layer the berries and the single creamy mixture in small glass jars or tumblers, keeping the same ratio of fruit to cream so the dessert still feels balanced rather than overly rich.
