Terrariums aren't just for the garden. Make this super cute dessert recipe in a small mason jar, layered with ingredients that look like they came from nature and you've got a terrarium you can eat! With a mug cake as the base and layered with pudding, graham crackers, and candy, it's essentially a trifle recipe.
Coat jars with nonstick cooking spray. In a small bowl whisk together flour, sugar, cocoa powder, baking powder and salt. Make a well in the center and add milk, butter and vanilla. Divide batter among the 4 jars and microwave all the jars, covered with a damp paper towel, on HIGH for 90 seconds or until cooked through. Cool completely in jars on wire rack.
Meanwhile, transfer melted candy coating to a small resealable plastic bag. Pipe small plants and leaves on a sheet of parchment or waxed paper and let stand until set.
Divide pudding among jars, spreading pudding evenly over cakes. Sprinkle with graham cracker crumbs, chocolate rocks, and chocolate mushrooms. Pipe small mounds of green frosting into each jar. Insert green candy coating leaves and plants.
