The part that usually stops me at tiramisu is the ladyfinger. Soaked, sugared, and baked into the structure of the whole dessert, with no sugar-free version of it that behaves the way the recipe needs it to.
This sugar-free biscoff tiramisu skips the cookies entirely and bakes a spiced almond crumble that does the same job. It gives the dessert a cookie layer that holds up to coffee, keeps its shape in the glass, and tastes like the spiced biscuit everyone is really after anyway.
That is the whole idea. Blanched almond flour, oat fiber, granulated allulose, melted butter and a teaspoon of apple pie spice come together in a lined 8-inch pan, bake 12 to 14 minutes until golden and fragrant, then get broken into irregular cookie crumbs. Half of that crumble goes in as the bottom of each glass, the rest goes in the middle.
Strong brewed coffee goes over both crumb layers, spooned on lightly enough to moisten without flooding. The cream is Neufchatel beaten with finely powdered allulose and FAGE Total 0%, which is what gives you the pale, thick, faintly tangy filling without mascarpone.

Why You’ll Love This Sugar-Free Biscoff Tiramisu
- The cookie layer is baked, not faked. A real spiced crumble, broken into irregular cookie crumbs after it comes out of the oven, does the job the soaked ladyfinger does in a classic tiramisu.
- Coffee, not a coffee flavor. A third of a cup of strong brewed coffee goes between the layers, which is enough to wake up the spice without turning the glass into soup.
- A cream that sets on its own. Neufchatel and thick Greek yogurt need no gelatin and no whipped cream, so there is nothing to fold in and nothing that can deflate overnight.
- Six portions, already divided. Every layer is spooned straight into the serving glass, so there is nothing to slice and nothing to plate.
- About 3g net carbs a cup. Six servings at roughly 158 calories each, with 8g protein.
How This Differs from Tiramisu Mousse Cups
There is already a tiramisu on this site, and this is not a renamed version of it. The sugar-free tiramisu mousse cups are a no-bake mousse.
Gelatin sets a whipped base into plain, dark cocoa and light cocoa layers, they get piped into three glasses in four clean bands, and each one finishes with a whipped cream rosette and a cocoa dusting. No oven, no crumbs, no coffee soaked into anything.
This one runs in the opposite direction. The structure comes from a crumb layer baked in a pan, not from whipped mousse set with gelatin.
The spice comes from a teaspoon of apple pie spice in the crumble, which is where the Biscoff character lives, and the coffee goes in as a real soaked layer rather than as espresso folded through the cream. The result eats more like a cookie tiramisu, with texture in every spoonful, where the mousse cups eat like a cold chocolate pudding.
If you want the mousse version, the sugar-free mocha cream pie takes the same coffee-and-cocoa idea further, with espresso, cocoa and Greek yogurt under a chocolate drizzle. For a spiced cookie to eat alongside this one, the sugar-free ginger-spice cookies lean on almond flour, oat fiber and allulose the same way, and bake soft with ginger leading and cinnamon behind it.
Ingredient Notes for the Sugar-Free Biscoff Tiramisu
For the Biscoff-style crumble
Blanched almond flour (½ cup, 56g) is the base of the cookie layer, and blanched is the word that matters. It is pale and fine, which is what keeps the crumbs looking like crumbs instead of gravel. Oat fiber (about 2 tbsp + 2 tsp, 8g) gives the mixture its bulk and stops it from baking into a solid sheet.
Melted unsalted butter (1 tbsp + 1¼ tsp, 20g) and water (1 tbsp, 15g) are what bring it together into something you can press loosely with your fingers. None of that shows in the finished cup, and all of it is what keeps the sugar-free biscoff tiramisu tasting like a cookie rather than like a nut.
The apple pie spice (1 tsp, 2g) is doing the Biscoff work, so measure it and do not eyeball it. Warm cinnamon and clove-heavy biscoff-style crumbs are what separate this from a plain coffee crumble. The crumble gets 30g of the granulated allulose while it is mixed, and the other 60g gets powdered for the cream, so measure it before you start.
Allulose is a rare sugar that the FDA allows to be excluded from the total sugars and added sugars declarations on the Nutrition Facts label, and it is the only sweetener in this recipe. My guide to sugar-free sweeteners for baking covers why it browns and caramelizes the way it does, and how it compares to the other options.
For the coffee and the cream
Strong brewed coffee (⅓ cup, 80g), cooled is the liquid layer, and cooling it matters. Coffee poured hot into the cream thins it and melts the layers. Brew it strong, because 80g is all the moisture these six cups get and weak coffee barely registers once the crumb has taken it up.
The cream is a two-ingredient affair. Philadelphia 1/3 Less Fat Neufchatel (4 oz, 113g), softened, beaten with the powdered allulose gives it body, and FAGE Total 0% plain Greek yogurt (1 cup, 227g) mixed in on low gives it the tang that keeps a 240g-tall cup of cream from reading as sweet.
Brick-style Neufchatel and thick Greek yogurt are the two things not to substitute. Loose yogurt gives you a thin cream that never sets into layers, and it is the one component the sugar-free biscoff tiramisu cannot do without.
For the finish
HERSHEY’S natural unsweetened cocoa powder (1 tbsp, 5g) goes on at the very end, sifted, right before the cups leave the fridge. Dust them too early and the moisture in the cream glues the cocoa into a flat brown lid.
The two tablespoons of crumble you hold back from the pan are the other half of the finish, and they go on with the cocoa. Those last two touches are what make the sugar-free biscoff tiramisu look like it came from a bakery case.
How to Make This Sugar-Free Biscoff Tiramisu
1. Heat the oven and mix the crumble
Heat oven to 325°F (165°C). Line the 8×8-inch metal baking pan with parchment. Mix the almond flour, oat fiber, 30g of the granulated allulose, the apple pie spice, the melted butter and the water together until everything holds together in moist crumbs.
2. Press, bake and cool
Press the mixture loosely in the pan. Loose is the instruction that matters here; packing it down hard gives you a slab that bakes into a single piece. Bake 12–14 minutes until golden and fragrant.
Cool it 20 minutes, then break it up into irregular cookie crumbs with your hands. Hold back 2 tablespoons for the topping.
3. Beat the tiramisu cream
Beat the softened Neufchatel with the powdered 60g of allulose until smooth. Then mix in the Greek yogurt on low until the whole thing is thick and creamy. Give the Neufchatel real time on the counter first, because cold cream cheese never fully smooths out and the lumps show up in the glass.
4. Start the layers
Divide half the crumble among the six glasses, roughly 2 tablespoons in the bottom of each. Spoon a little cooled coffee over each layer, enough to moisten the crumbs without flooding the bottom of the glass. Everything after that is assembly, so this first layer sets the tone for the whole sugar-free biscoff tiramisu.
5. Repeat the layers
Add half the cream on top of the coffee, then repeat with the remaining crumble, the rest of the coffee, and the rest of the cream. The last thing into each glass is cream, which means every cup gets a smooth pale top for the cocoa to land on.
6. Chill
Cover the glasses and chill at least 4 hours. That is the whole job for this stage, and there is no shortcut around it. The cream needs the time to firm up enough to hold a clean layer edge and for the coffee to stop moving through the crumb.
7. Finish and serve
Just before serving, sift the cocoa lightly over each cup and scatter the reserved spiced crumbs over the top. Do this at the table rather than in advance, because the crumbs pick up moisture from the cream the longer they sit on it.
Success Tips for the Sugar-Free Biscoff Tiramisu
- Let the crumble cool fully before layering. Warm crumbs laid into cold cream melt it, and you lose the cookie texture that is the whole point.
- Moisten the crumbs gradually. Too much coffee is what makes the layers soggy. Spoon it on, look at the glass, then add more if the crumbs are still dry.
- Use brick-style Neufchatel and thick Greek yogurt. Both are doing structural work. Neufchatel holds the cream together and thick yogurt keeps it from sliding off the crumb layer.
- These are homemade spiced Biscoff-style crumbs. Not sugared Biscoff cookies stirred into the layers, and not a store-bought cookie in any form. The spice is in the crumble you bake yourself.
- Break the cooled crumble by hand. A food processor gives you uniform powder, and you want the irregular pieces that taste like a cookie.
- Pour the coffee over, not into. A small spoon back and forth across the crumbs distributes it evenly and keeps one spot from turning to mud. That single habit is the difference between a sugar-free biscoff tiramisu with a soft crumb layer and one with a wet one.
Storage
Cover the glasses and keep them in the refrigerator. This sugar-free biscoff tiramisu is built to be made ahead: chill the assembled cups for at least 4 hours, then dust the cocoa and add the reserved crumbs when you are about to serve.
The coffee keeps working into the crumb layers as they wait, so the longer a cup sits after assembly, the softer that cookie layer gets. If you are holding them, keep the cocoa and the crumbs off until serving time.
FAQ
Can I use Biscoff cookies instead of baking the crumble?
Not in this recipe. This sugar-free biscoff tiramisu bakes its spiced crumble from almond flour, oat fiber, allulose, butter and apple pie spice, and it is meant to replace the sugared cookie entirely.
Store-bought Biscoff cookies are sweetened with sugar, and they turn to paste in the coffee rather than holding their shape. The success note on this one is simple: homemade spiced Biscoff-style crumbs, not sugared cookies.
How long do the cups need to chill?
At least 4 hours after assembly. The full 4 hours 20 minutes in this recipe covers the 20 minutes the crumble cools before it is broken up and layered, plus the 4 hours the filled glasses sit in the fridge.
Does the cream need gelatin or whipped cream?
No. This sugar-free biscoff tiramisu sets the cream on its own: Neufchatel beaten with powdered allulose and mixed with thick Greek yogurt, then 4 hours in the fridge. There is nothing to whip, nothing to fold, and nothing that goes flat while the dessert waits.
Why does the coffee have to be cold?
Because it goes straight onto the crumb layer and under the cream. Warm coffee thins the cream as it spreads and softens the crumbs faster than they can absorb it. Brew it ahead, cool it, and keep it in a small pitcher so you can spoon it on without flooding any one glass.
How do I stop the layers from going soggy?
Moisten the crumbs gradually instead of pouring. Spoon a little coffee over each crumb layer, let it soak in, and add more only where the crumbs still look dry.
The goal is damp crumbs that hold together when you press the top with a spoon, not a puddle in the bottom of the glass. If you are making these sugar-free biscoff tiramisu cups for a crowd, spoon the coffee over each glass one at a time rather than pouring it in a batch.
That is the whole recipe: a baked spiced crumble, strong coffee, and a cream that sets in the fridge, layered into six glasses and finished with cocoa and the crumbs you saved. If you would rather skip the coffee entirely, the sugar-free no-bake peanut butter chocolate cups use the same chilled-dessert-in-a-glass idea with a peanut shell and a dark chocolate top.
