A keto version of trifle, with no flour or added sugar: individual dessert glasses with three layers, almond biscuit, avocado chocolate mousse and lemon cream.
From the first spoonful, the almonds provide crunch, the raw cacao adds intensity and the lemon cream cuts through with a fresh, vanilla-scented note. This keto trifle is assembled in individual dessert glasses, with no sponge cake or added sugar, built around three layers: an almond biscuit, an avocado chocolate mousse and a tangy lemon cream. For six small dessert glasses, allow around 24 hours of resting time, with 10 minutes of baking. This recipe joins my collection of keto desserts.
What is keto trifle?
Trifle is a spoonable dessert assembled in clearly visible layers in a glass. Here, each element has its role: the biscuit provides crunch, the mousse adds chocolate flavor and the lemon cream brings acidity. Its appeal lies as much in the presentation as in the contrasting textures, especially when the layers stay distinct in a clear dessert glass.
In this version, erythritol replaces added sugar and ground almonds form the biscuit base instead of wheat flour. Vanilla-scented lemon cream and avocado chocolate mousse replace the usual fillings of custard, fruit and whipped cream. The recipe contains no alcohol; the finishing touches are optional and should remain low in carbohydrates.
The origins of this version
Trifle comes from the English tradition of layered desserts, with cake, custard and fillings stacked in a large glass bowl. This adaptation keeps the visual effect of the layers while adjusting it to suit a ketogenic or reduced-carbohydrate diet.
The almond biscuits provide texture, the lemon cream brings tangy freshness and the avocado chocolate mousse adds body without added sugar. The balance comes from the richness of the almonds, butter and avocado, offset by the acidity of the lemons and the bitterness of the raw cacao. Expect around 763 kcal per serving, a rich dessert designed for small portions.
The main ingredients
The biscuit is made with 100 g of ground almonds, which replace a wheat-flour base and provide flavor and structure after baking. Two egg whites bind the dough, 25 g of powdered erythritol sweeten it without added sugar, a teaspoon of almond extract enhances the aroma and a pinch of salt brings everything together.
The mousse is based on 4 to 5 ripe avocados, blended until smooth and firm. 40 g of unsweetened raw cacao provide the intense chocolate flavor, 20 g of erythritol soften the bitterness and 6 tablespoons of unsweetened almond milk loosen the mixture to make assembly easier.
The vanilla-scented lemon cream calls for 10 to 12 egg yolks at room temperature, the juice and aroma of 5 to 6 lemons, 275 g of butter for a melt-in-the-mouth texture that holds its shape when chilled, 80 g of erythritol for restrained sweetness and 5 teaspoons of Bourbon vanilla powder, or 4 vanilla pods. To finish, shavings of very low-sugar dark chocolate or a little candied lemon are optional, provided you keep an eye on their sugar content.
Technical tips and serving
This dessert is prepared ahead of time: 24 hours 20 minutes in total, including resting time and 10 minutes of baking. The biscuits are best baked the day before and will keep for 24 hours in their baking parchment, away from the moist components. Keep the lemon cream covered in the refrigerator; take it out at least 1 hour before assembly so it can soften. Make the chocolate mousse at the last minute, or a little earlier to save time during assembly.
For well-defined layers, break the biscuits into evenly sized pieces rather than crumbs, and keep the mousse soft enough to spread without crushing the base. Spoon the mousse and cream into the center of the glass, then gently push them toward the edges to keep the layers neat. Small, clear dessert glasses show off the colors, and a piping bag helps you fill them precisely. Amaretto or limoncello can be served separately on the side; poured over the biscuits, they take the dessert out of low-carb territory.

Keto trifle
Ingredients
- 100 g ground almonds
- 2 egg whites
- 25 g powdered erythritol
- 1 teaspoon almond extract
- pinch salt
Vanilla lemon curd
- 10 to 12 egg yolks at room temperature
- 5 to 6 lemons
- 275 g butter from grass-fed cows
- 80 g powdered erythritol
- 5 teaspoons Bourbon vanilla powder or 4 pods
Chocolate mousse
- 4 to 5 avocados ripe
- 40 g raw cacao powder
- 20 g powdered erythritol
- 6 tablespoons almond milk
Optional
- dark chocolate
- candied lemon
Instructions
- Prepare the layers the day before or in the morning. This is actually preferable for the biscuits, as they will taste even better, and the curd needs some time to cool. The chocolate mousse does not need to be made ahead, but it is nice to have it ready when you are preparing an entire dinner.
- Make bitter almond biscuits. The recipe makes 6 biscuits. Allow approximately 1 biscuit per layer (a little more at the bottom of a wide wine glass, a little less in a narrow glass). To store them for a day, wrap them in the baking paper they were baked on.100 g ground almonds, 2 egg whites, 25 g powdered erythritol, 1 teaspoon almond extract, pinch salt
- Make a vanilla lemon curd for the curd layer. Please note: this is the basic recipe. For the trifle, however, use more than the amount specified in the basic recipe. The basic recipe makes enough for just over 2 layers. For 6 layers, allow approximately 3x this quantity; a little less may also be perfectly sufficient (I can never resist sneaking a taste). If you make the curd the day before, keep it in the refrigerator. Take the curd out of the refrigerator at least an hour beforehand, otherwise it will be far too firm. If you make it in the morning, keep it covered at room temperature (not too warm). Stir well before using (the dissolved erythritol may recrystallise slightly in the refrigerator).10 to 12 egg yolks, 5 to 6 lemons, 275 g butter, 80 g powdered erythritol, 5 teaspoons Bourbon vanilla powder
- For the chocolate mousse, take 4 to 5 ripe avocados. Blend them with the cacao and erythritol using a hand blender. This will give you a firm mousse. Loosen it a little for the trifle, otherwise the trifle will be too dense and the glasses will also be harder to fill. To do this, add plant-based milk. The amount depends somewhat on how creamy the avocados are. Not a fan of avocados? Choose a chocolate mousse made with egg and butter instead (so no avocado, but still no milk or cream).4 to 5 avocados, 40 g raw cacao powder, 20 g powdered erythritol, 6 tablespoons almond milk
- Assembling the trifle is simple. Crumble a biscuit into bite-sized pieces. Spoon the mousse on top, then the curd on top of that. Start by placing the curd or mousse in a small mound in the middle, then push it out from the centre towards the edges. This is easier than spooning it directly against the sides.dark chocolate, candied lemon
- Originally, a trifle was made with rum-soaked cake. I have not used any alcohol here, but for those who enjoy it, a small glass of amaretto (at room temperature) or limoncello (straight from the freezer!) makes a perfect accompaniment. Choose whether to serve it separately or soak the biscuits in it first. Of course, the dessert will then no longer be moderate in carbs ๐
