Microwave Chocolate Brownie in a Mug Cake

Coat the interior of a 6-ounce mug with cooking spray. Set aside.

In a small bowl, whisk together the flour, sugar, cocoa powder, and salt to combine.

In a separate small bowl, whisk together the oil and egg. Pour the oil-egg mixture into the flour mixture and mix until just combined.

Pour half the batter in the mug, and add half the preserves and half the coconut. Pour the remaining batter in the mug, followed by the remaining preserves and coconut.

Cover with plastic film and microwave until just cooked in the center, about 90 seconds. Serve immediately.
