Method
- Make the cocoa mixture. Combine the ground cookies, powdered sugar, cocoa powder, and rum in a bowl. Add the warm milk and mix thoroughly until a uniform, soft dough forms.
- Roll out the cocoa layer. Place the dough inside a large freezer bag. Press out excess air and use a rolling pin to spread it into an evenly thick rectangle. Carefully cut the bag open like a book and peel back the upper piece of plastic. Leave the cocoa layer on the bottom piece.
- Prepare the coconut filling. Beat the softened butter and powdered sugar until smooth and creamy. Mix in the desiccated coconut until evenly combined.
- Roll out the coconut layer. Transfer the filling to a second freezer bag of the same size. Roll into a rectangle matching the cocoa layer. Cut the bag open and peel back the upper piece of plastic.
- Stack the layers. If the cocoa layer still feels warm, let it cool first. Use the remaining plastic to lift and turn the coconut layer onto the cocoa layer, with the exposed filling facing down. Align the edges and gently remove the plastic from the top.
- Shape the roll. Starting at one edge, use the plastic beneath the cocoa layer to help roll both layers into a snug log. Peel the plastic back as you go, keeping it out of the roll.
- Coat and chill. Gently roll the log in extra coconut. Wrap in plastic wrap and refrigerate for at least 2 hours, until firm.
- Slice and serve. Unwrap and cut into 32 thin slices with a sharp knife, wiping the blade between cuts.
Notes
- Measurements: US measurements are approximate. For the closest result, use the gram and milliliter quantities.
- Cookies: Use finely ground plain cookies without filling or coating. Different brands may absorb milk differently.
- Coconut: Use finely shredded, unsweetened desiccated coconut rather than coconut flour.
- Butter: Soften before mixing; do not melt.
- Smaller rolls: Divide both mixtures into equal portions and use matching smaller freezer bags.
- Make ahead: Prepare the roll the day before and refrigerate overnight.
- Storage: Keep tightly wrapped or in an airtight container in the refrigerator and enjoy within 3-4 days.
- Freezing: Wrap well and freeze for up to 1 month for best quality. Thaw in the refrigerator.
- Nutrition: Estimates use plain tea cookies, unsalted butter, whole milk, 1 tablespoon of rum, and approximately 10 g of extra coconut for coating.
