Milk Cream Recipe

Prepare thickening slurry

In a small bowl, whisk the cornstarch with 2 tablespoons of the cold whole milk until fully dissolved and no lumps remain. Set aside.

Heat milk and cream

Combine the remaining whole milk (just under 4 cups if you reserved some for slurry) and the heavy cream in a medium saucepan. Add the granulated sugar and salt. If using a vanilla bean, split it lengthwise, scrape the seeds into the milk, and add the pod as well. If using vanilla extract, wait to add it later. Warm the mixture over medium heat, stirring occasionally, until it reaches a gentle simmer (small bubbles around the edge) but do not boil.

Thicken the mixture

Once the milk mixture is simmering, remove about 1/2 cup of the hot liquid and whisk it into the cornstarch slurry to temper it. Pour the tempered slurry back into the saucepan while whisking continuously. Continue to cook over medium-low heat, whisking, until the mixture thickens to a light custard consistency and coats the back of a spoon, about 2–4 minutes. Do not let it boil vigorously.

Finish flavor and texture

If using vanilla extract, stir it in now (about 1 tablespoon). Remove and discard the vanilla pod if used. Off the heat, stir in the unsalted butter until melted and fully incorporated for a silkier mouthfeel.

Bloom gelatin (optional)

If you want a firmer, sliceable milk cream (for tarts or layered desserts), sprinkle the gelatin over 1 tablespoon cold water and let bloom for 5 minutes. Warm the bloomed gelatin gently (10–15 seconds) until liquefied and stir it into a small amount of the hot milk cream, then whisk that back into the rest of the mixture until fully combined.

Transfer the milk cream to a heatproof bowl or shallow container. Press a piece of plastic wrap directly onto the surface to prevent a skin from forming. Let cool to room temperature (about 20–30 minutes), then refrigerate until thoroughly chilled and set, at least 2 hours (longer if gelatin was used).

Before serving, whisk the chilled milk cream briefly to restore a smooth texture. Use as a pouring cream over desserts, a filling for pastries, or chill until firmer and slice for layered cakes or tarts.
