Easy Stovetop Chocolate Banana Mug Cake

1.Prepare the Stovetop Steamer: Fill a medium saucepan with about 1 inch of water. Place a steaming rack or a small trivet inside the saucepan. Cover the saucepan and bring the water to a gentle simmer over medium heat.

2.Mix Wet Ingredients: In a microwave-safe mug (or any sturdy, heat-safe mug that fits in your steamer), thoroughly mash the ripe banana until smooth. Whisk in the egg, milk, and oil until well combined.

3.Combine Dry Ingredients: In a separate small bowl, whisk together the flour (maida), cocoa powder, sugar, baking powder, and salt until no lumps remain.

4.Form the Batter: Add the dry ingredients to the wet ingredients in the mug. Use a fork to gently mix until just combined. Do not overmix; a few small lumps are acceptable. Stir in any optional chocolate chips now.

5.Steam the Cake: Carefully place the mug onto the steaming rack inside the saucepan. Ensure the water level does not reach the top of the mug.

6.Cook: Cover the saucepan tightly and reduce the heat to low-medium, maintaining a steady, gentle steam. Steam the cake for 15 to 20 minutes. Do not lift the lid for the first 15 minutes.

7.Check for Doneness: After 15 minutes, carefully insert a toothpick into the center of the cake. If it comes out clean or with moist crumbs attached (not wet batter), the cake is done. If not, steam for another 3-5 minutes.

8.Serve: Carefully remove the hot mug from the steamer using oven mitts. Let it cool for 2-3 minutes before enjoying directly from the mug, optionally topped with powdered sugar.
