1. Start by soaking the gelatin in 3 tablespoons of cold water. Let it bloom for about 5 minutes while you prepare the custard base.
2. Split the vanilla bean lengthwise and scrape out the seeds. Combine the milk, vanilla seeds, and the pod in a medium saucepan. Heat gently over medium heat until it just starts to simmer. Remove from heat and let it infuse for 10 minutes. If you’re using vanilla extract, add it later with the sugar.
3. In a separate bowl, whisk together the egg yolks and sugar until pale and slightly thickened—this helps give the cream its smooth texture.
4. Slowly pour the warm milk into the egg yolk mixture in a thin stream, whisking constantly to prevent the eggs from scrambling.
5. Return the mixture to the saucepan and cook over low heat, stirring constantly with a wooden spoon or spatula, until it thickens enough to coat the back of the spoon (about 170°F or 77°C). Be patient here; rushing can curdle the custard.
6. Remove the custard from heat, discard the vanilla pod if used, and stir in the bloomed gelatin until fully dissolved. If you’re using vanilla extract, add it now.
7. Pour the custard into a bowl and let it cool to room temperature, stirring occasionally to prevent a skin from forming.
8. While the custard cools, whip the heavy cream to soft peaks. This means when you lift the whisk, the cream should hold its shape but still be slightly soft.
9. Gently fold about a third of the whipped cream into the custard to lighten it, then carefully fold in the remaining cream until fully incorporated. This folding technique keeps the cream airy and light.
10. Wash and prepare your berries. If you like, toss them with a tablespoon of lemon juice to brighten their flavor.
11. Pour half of the Bavarian cream into serving dishes or a large mold, then scatter a layer of berries on top. Add the remaining cream and finish with a few berries on top for garnish.
12. Cover and refrigerate for at least 4 hours, preferably overnight, until set.

Over the years, I’ve found that patience is key with this dessert. Rushing the chilling process can mean a creamier but less structured finish. When I’m cooking for my family, I often prepare this the day before so I can enjoy those slower moments rather than last-minute stress.
