A creamy, festive frozen dessert with a classic red velvet and cheesecake-inspired flavor. It is a memorable treat for celebrations or relaxed weekends.
Heat the oven to 350 degrees F and line a small loaf pan with parchment paper. Whisk the flour, cane sugar, cocoa powder, baking soda, and sea salt in a bowl.
Stir the oat milk, avocado oil, vinegar, vanilla, and red food coloring into the dry ingredients. Spread the batter in the prepared pan and bake for 14 to 17 minutes, or until the center springs back when lightly touched.
Cool the red velvet cake completely. Crumble it into bite-size clusters and freeze the clusters for at least 30 minutes.
Whisk the coconut milk, oat milk, cane sugar, cornstarch, cocoa powder, vanilla, red food coloring, and sea salt in a saucepan. Cook over medium heat until steaming and slightly thickened.
Blend the warm mixture with the dairy-free cream cheese and lemon juice until completely smooth. Refrigerate the cheesecake base for at least 4 hours.
Churn the cold base according to the ice cream maker's directions. Add two-thirds of the frozen red velvet cake during the final 2 minutes.
Transfer to a freezer-safe container and layer in the remaining cake clusters. Freeze for 4 to 6 hours, then soften briefly at room temperature before serving.
