Combine oat milk, cocoa powder, tahini, maple syrup, caramel essence and salt in a blender.
Blend on medium speed until well combined, about 30 seconds, scraping down the sides of the blender.
Add the melted coconut oil and blend until combined, about 20 seconds. The pudding will be runny at this point, but it will firm up as it chills.
Pour the pudding into 4 individual jars.
Chill until firm, at least 2 hours.
Serve with toppings if desired. Recipe inspired by BojonGourmet
