being a bit denser or having a subtle coconut flavor, but it can still yield a delicious frozen treat. Ensure all other ingredients like cocoa powder and milk for the swirl are also dairy-free.
How can I prevent the chocolate swirl from just mixing into the vanilla base?
The key to a beautiful, distinct swirl is gentle handling and not over-swirling. After spooning the chocolate dollops onto the vanilla base, use a knife, skewer, or chopstick to make just a few passes through the layers. Aim for a figure-eight or zig-zag motion, making sure to reach the bottom layer, but stop as soon as you see a marbled pattern forming. If you continue to swirl, the colors will eventually blend and become muddy. It also helps if your chocolate swirl mixture is thick enough to hold its shape somewhat, rather than being too runny.
