Tiramisu mug cake with mashed banana

Here's a perfect portion of warm, coffee-infused cake that you can whip up and enjoy in under 5 minutes. We added an extra hint of flavor and texture by stirring sweet, ripe mashed banana into the mix. For a pretty presentation, follow the same recipe but prep it in a small glass ramekin that's been coated with cooking spray. Bake at 350°F until cooked through, about 12 to 14 minutes. Enjoy as is or garnish with a few raspberries or sliced strawberries. A dusting of powdered sugar is also nice.
