In a blender or a large bowl with an immersion blender, combine the almond milk, cottage cheese, whipping cream, egg, vanilla extract, 1 tablespoon (15 ml / 0.5 fl oz) of stevia, and glucomannan powder.
Blend on high until the mixture is completely smooth and homogenous, ensuring no lumps from the cottage cheese remain.
In a separate small bowl, whisk together the melted coconut oil, cocoa powder, and 1 teaspoon (5 ml / 0.2 fl oz) of stevia until a smooth chocolate sauce forms. If your coconut oil is solid, gently heat the in a small saucepan over low heat until just melted and combined.
Pour the ice cream base into a freezer-safe, loaf-pan-style container.
Place it in the freezer for 20-30 minutes, or until the edges just begin to set.
Remove the container from the freezer. Dollop the peanut butter over the surface of the semi-frozen ice cream and drizzle the chocolate sauce over the top.
Using a butter knife or a skewer, gently pull the knife through the mixture to create beautiful swirls of chocolate and peanut butter.
Do not overmix.
Cover the container and return it to the freezer for at least 4-6 hours, or until firm.
Let it sit at room temperature for 5-10 minutes before scooping to serve.
Let the finished ice cream sit on the counter for 5-10 minutes before serving. This short thaw time makes for a much creamier and easier scooping experience.
