Keto Tiramisu Mousse — Keto Tiramisu Recipe (Easy, Coffee-Kissed Chocolate Delight)

Keto Tiramisu Mousse arrives like a tiny, elegant party in a glass — coffee, chocolate, and creamy mascarpone vibes, but low-carb. If you love the classic tiramisu flavor and want something quick, no-bake, and totally decadent, this mousse will become your go-to dessert.

Introduction — what this dessert is and why it works

This recipe layers whipped mascarpone and cream with espresso and cocoa for that unmistakable tiramisu profile, but in a light, airy mousse format. It tastes like a grown-up dessert you’d order at a restaurant, yet it takes minutes to assemble. Keto Tiramisu Mousse gives you the indulgence of a classic tiramisu without the carbs — and honestly, who doesn’t want that?

Why you’ll love it right away

• Super fast and no baking required — assemble and chill.
• Low carb and keto-friendly — sweetened with a sugar substitute, so a single serving keeps carbs low.
• Looks fancy — serve in glasses for an impressive dessert that screams “I tried,” even if you barely broke a sweat.
• Versatile — make it into Keto Tiramisu Cups for parties, or pile it in a trifle bowl for family style.

The story behind this mousse (short & sweet)

I fell for tiramisu the usual way — one spoonful and I was hooked. But I didn’t always want the fuss of ladyfingers or a water bath. Turning tiramisu into a mousse keeps the soul of the dessert (coffee + creamy layers + cocoa) while ditching extra steps. It’s inspired by classic recipes but modernized for low-carb living and busy weeknights. Perfect win.

Ingredients — what you need and why each item matters

Here’s a simple ingredient breakdown with short notes so you know what each part does:

• Mascarpone cheese — the heart of tiramisu; silky and slightly sweet. Use full fat for best texture.
• Heavy whipping cream — gives volume and lightness when whipped; it turns the mascarpone into mousse.
• Unsweetened cocoa powder — the bitter chocolate counterpoint to coffee; essential for flavor layering.
• Powdered erythritol (or preferred keto sweetener) — keeps the dessert sweet without spiking carbs. Powdered helps it dissolve smoothly.
• Strong espresso or very strong coffee — the coffee backbone. Instant espresso dissolved in hot water works perfectly.
• Espresso powder (optional, for dusting) — concentrated coffee flavor for finishing flourish.
• Vanilla extract — lifts and rounds flavors.
• Pinch of salt — balances sweetness and enhances chocolate.

(These are the core items — precise amounts sit in the recipe card below.)

How to make it — simple step-by-step

This is the no-nonsense method I use every time. Keep paragraphs small and the process breezy.

1. Chill your mixing bowl and beaters — cold tools = faster, firmer peaks.
2. Combine mascarpone, vanilla, espresso, powdered erythritol, salt, and half the cocoa powder in a large bowl. Gently mix to dampen the powders so cocoa doesn’t puff everywhere.
3. Whip the heavy cream until soft peaks form.
4. Fold the whipped cream into the mascarpone mixture in two additions. Use a rubber spatula and lift the mix — don’t beat it flat. Aim for light, pillowy mousse.
5. Layer into serving glasses: mousse, a dusting of cocoa, repeat 2–3 layers. Top with a sprinkle of espresso powder if you want that intense coffee hit.
6. Chill for at least 30 minutes (longer = better), then serve cold garnished with a couple of coffee beans or a few shavings of dark low-carb chocolate.

Pro tip: Use a piping bag for neat, restaurant-style layers.

Pro tips for perfect mousse every time

• Chill your bowl and whisk. Cold gear whips cream faster and gives sturdier peaks.
• Don’t overmix. Fold gently to preserve air — the difference between mousse and dense pudding is subtle but real.
• Use powdered erythritol (not granulated) so it dissolves without graininess. If you use monk fruit blends, check the manufacturer’s conversion.
• If mascarpone feels grainy, give it a quick blitz in a food processor before folding.
• Make ahead: assemble and refrigerate up to 3 days. Sprinkle espresso powder right before serving for the freshest aroma. Big win for dinner parties.

Bold tip: Let the mousse sit in the fridge for at least 30–60 minutes — chilling amplifies the flavor and firms the texture.

Variations — easy swaps and fun upgrades

Want to mix things up? Here’s how to riff on the base:

• Keto Tiramisu Cups: Layer the mousse in small cups and top with crushed low-carb cookies or cocoa nibs for crunch.
• Chocolate forward: Swap half the cocoa for fine unsweetened melted dark chocolate (cooled) for a Keto Chocolate Cheesecake Mousse vibe.
• With cream cheese: Fold in a little cream cheese to morph into Keto Chocolate Mousse With Cream Cheese — richer, cheesecake-adjacent.
• No mascarpone option: Use an equal blend of cream cheese + heavy cream whipped for a Keto Tiramisu Recipe Without Mascarpone alternative — still lush.
• Berry twist: Serve with raspberries for a tart contrast — berries are lower-carb and add great color.
• Nutty crunch: Add crushed toasted almonds between layers for texture.

FYI: These variations let you turn one recipe into several signature desserts.

Best ways to serve this mousse

• Serve chilled in individual glasses — Keto Tiramisu Cups feel elegant and are portion-friendly.
• Garnish with a dusting of espresso powder, cocoa, a couple of coffee beans, or a thin curl of low-carb dark chocolate.
• Pair with a tiny spoonful of fresh berries or a mint leaf for a refined plate.

Want to impress? Bring the mousse to the table in a pretty tray with matching spoons — instant wow factor.

Storage & leftovers

• Fridge: Store in an airtight container or keep glasses covered with plastic wrap for up to 3 days.
• Freeze? You can freeze portions, but texture shifts — thaw overnight in fridge before serving. I prefer fresh or chilled rather than frozen.
• Make-ahead: Perfect for prepping the night before. Keep the top layer unsprinkled until serving.

Quick tip: If the mousse loosens after refrigeration, a quick whip with a spatula restores loft.
