Store-bought chocolate syrupor use the recipe above
Cocoa powder for sprinkling
Instructions
Make the milkshakes.
Combine the cashews, ice, oat milk, cocoa powder, sugar, salt, and vanilla in a high-speed blender. Blend on high speed until the mixture is smooth and creamy, a minute or two.
Make the coconut whip.
Combine the chilled coconut cream, aquafaba, ice cubes, agave nectar, and vanilla in a container with a tight-fitting lid. Shake vigorously for about a minute, until the mixture becomes light, fluffy, and doubled in volume.
Assemble.
Squirt chocolate syrup along the inside of your mason jars, swirling it into a fun pattern. Fill the jars with the chocolate milkshake, top generously with the coconut whip, dust lightly with cocoa powder, and insert a fun straw. Serve immediately.
