Biscuit-Based Lemon Bavarois is a sophisticated yet refreshing dessert, perfect for spring and summer gatherings. Light, citrusy, and airy like a mousse, Bavarois (also called Bavarian cream) is a classic French dessert made with custard, gelatin, and whipped cream.

When paired with a buttery biscuit base, it becomes an elegant showstopper. Line the bottom of your springform pan with parchment paper for easier release later. In a food processor (or by hand), crush 200g of digestive biscuits until they become fine crumbs.

Pour in 90g of melted butter, and if you like, a teaspoon of lemon zest to echo the flavour in the filling. Mix until the crumbs resemble damp sand. Then press the mixture evenly into the base of your pan, using the back of a spoon or a flat-bottomed glass.

Press firmly to create a compact layer — this will be the foundation for your silky lemon Bavarois. Pop the base into the fridge while you prepare the filling. Cold base = firm, crisp texture later. If you’re using gelatin powder, sprinkle 10g (1 tbsp) of it over 3 tablespoons of cold water in a small bowl.

Let it sit for 5–10 minutes to bloom. It’ll look wrinkled and thick when ready. If you’re using gelatin sheets, soak them in a bowl of cold water until soft — about 5–7 minutes — then squeeze out excess water before using. Set aside.

Now we begin the magic: the Bavarian cream itself. In a heatproof bowl, whisk together: 4 egg yolks and 100g sugar (½ cup). Whisk until the mixture is pale and slightly thick — about 1–2 minutes. In a small saucepan, gently heat 250ml of milk until just steaming (not boiling).

Slowly pour the hot milk into the egg mixture while whisking constantly — this tempers the yolks so they don’t scramble. Now pour the whole mixture back into the saucepan. Place over low to medium-low heat, and stir constantly with a rubber spatula or wooden spoon, making figure-eight motions.

You’re looking for the custard to thicken slightly — it should coat the back of a spoon. Don’t let it boil. Once it’s thickened, remove from the heat immediately. While the custard is still warm, stir in: 1 tbsp lemon zest and 100ml fresh lemon juice, then add your bloomed gelatin directly into the warm custard.

Stir gently until fully melted and incorporated. If needed, you can strain the custard through a fine mesh sieve into a clean bowl to remove any lumps or zest bits. Let the lemon custard cool to room temperature — it should still be fluid, but no longer hot. (Hot custard will melt the whipped cream in the next step.)

While the custard is cooling, whip 250ml of chilled heavy cream to soft peaks — not too stiff, or it won’t fold easily. Once the custard has cooled, gently fold the whipped cream into the lemon mixture in three additions.

Start with a large spoonful to loosen the base, then gently fold in the rest using wide, slow motions to keep the volume. You should now have a pale, airy, lemon-scented cream that feels like satin on a spoon. Remove your biscuit base from the fridge.

Pour the Bavarois mixture over the base, smoothing the top with a spatula. Tap the pan lightly on the counter to release any air bubbles. Cover and refrigerate for at least 6 hours, or preferably overnight. The gelatin needs time to fully set the mousse-like texture.

When ready to serve, gently run a knife around the edge of the pan to loosen, then release the springform ring. Top with whipped cream rosettes, lemon zest curls, or candied lemon slices for elegance.

A scattering of crushed meringue or white chocolate shavings adds lovely texture. Serve chilled — each slice should hold its shape, yet feel like a cloud when you cut into it.

Storage

Refrigerate covered for up to 3 days.
Not suitable for freezing (gelatin texture may degrade).
Best served cold and fresh, straight from the fridge.

Optional Variations;

Lemon-Lavender: Infuse the milk with a pinch of dried lavender before making the custard.
Lemon-Raspberry: Add a layer of fresh raspberries between the base and filling.
Citrus Mix: Combine lemon, lime, and orange zest/juice for a citrus medley.
Gluten-Free: Use gluten-free digestive biscuits or almond flour for the base.

This Biscuit-Based Lemon Bavarois is a showstopper — delicate yet full of flavour. The contrast of the crunchy biscuit base with the light-as-air lemon cream makes it the kind of dessert people remember and request again.

It’s ideal for dinner parties, holidays, or anytime you want to bring a little French flair into your kitchen — no baking required beyond the base, just patience, precision, and a whole lot of lemon love.
