Instructions
Step 1: Whip the cream. Pour the cold heavy cream into a large bowl and begin whipping with a hand mixer or whisk. After about 30 seconds of whipping, add the condensed milk and vanilla extract. Continue whipping until the cream forms soft to medium peaks — it should hold its shape when the whisk is lifted but still have a gentle, billowy quality rather than being stiff. Do not overwhip or the cream will become grainy and eventually turn to butter. The entire whipping process takes about 2 to 3 minutes with a hand mixer or a bit longer with a whisk.
Step 2: Crush the biscuits. Place the biscuits in a zip-lock bag and crush them with a rolling pin until you have a mixture of fine crumbs and slightly larger pieces. You want some variation in size — pure fine crumbs produce a uniform sandy texture, while having some larger pieces gives more textural interest. Alternatively, break them coarsely by hand directly into the serving cups.
Step 3: Assemble the cups. In four glasses, cups, or small bowls, begin layering. Add a layer of crushed biscuits to the bottom of each cup and press gently to compact it slightly. Dust lightly with cocoa powder through a fine sieve or small strainer. Add a generous layer of the whipped cream mixture. Add another layer of biscuit crumbs. Dust again with cocoa powder. Finish with a final layer of cream and a dusting of cocoa powder on top. If using optional toppings, add them now. The layers should be clearly visible through the sides of the glass.
Step 4: Chill or serve immediately. These cups can be eaten immediately for a fresh, lighter texture, or refrigerated for 20 to 30 minutes — or up to several hours — for a richer, more set result where the biscuits have softened into the cream and the flavors have melded together. Most people strongly prefer the chilled version, which is genuinely better after at least 20 minutes in the refrigerator. The cups can be prepared up to 24 hours in advance and stored covered in the refrigerator.
Variation 1: 3-Ingredient No-Bake Chocolate Biscuit Balls
This version requires three ingredients and zero equipment beyond a bowl and your hands. Crush 200 grams of digestive or Marie biscuits into fine crumbs using a food processor or a zip-lock bag and rolling pin. In a separate bowl, whisk together one 14-ounce can of sweetened condensed milk and 3 tablespoons of unsweetened cocoa powder until the cocoa is fully dissolved and the mixture is smooth and uniform. Combine the biscuit crumbs with the condensed milk mixture and stir until everything is thoroughly combined. The mixture should be thick, slightly sticky, and hold its shape when pressed together. Refrigerate for 30 minutes to firm up, then roll tablespoon-sized portions between your palms into smooth balls. Roll each ball in additional cocoa powder, crushed biscuit crumbs, desiccated coconut, or sprinkles. Arrange on a plate and refrigerate until serving. These keep for up to a week in an airtight container in the refrigerator and actually improve over the first day as the flavors deepen.
