Ingredients

• 3 tablespoons Rolled oats
• 1 tablespoon Unsweetened cocoa powder
• 2 tablespoons All-purpose flour
• 1.5 tablespoons Brown sugar
• 0.25 teaspoon Baking powder
• 0.125 teaspoon Salt
• 3 tablespoons Milk (dairy or non-dairy)
• 1.5 tablespoons Vegetable oil
• 0.25 teaspoon Vanilla extract
• 1 tablespoon Chocolate chips (optional)

Directions

Step 1

In a microwave-safe mug or small bowl, combine the dry ingredients: rolled oats, unsweetened cocoa powder, all-purpose flour, brown sugar, baking powder, and salt. Stir well to ensure even distribution.

Step 2

Add the wet ingredients: milk, vegetable oil, and vanilla extract. Stir until a smooth, lump-free batter forms.

Step 3

If desired, fold in the chocolate chips for an extra indulgent touch.

Step 4

Tap the mug gently on the countertop to level the batter, ensuring an even cooking surface.

Step 5

Microwave on high for 1 minute and 30 seconds to 2 minutes, depending on the wattage of your microwave. The cake should rise and set but remain slightly moist in the center.

Step 6

Carefully remove the mug from the microwave (it will be hot). Allow the cake to cool for 1-2 minutes before serving.

Step 7

Enjoy the oatmeal chocolate cake directly from the mug, or invert it onto a plate for a more elegant presentation.
