Ingredients for Oatmeal Nutella Mug Cake
Gather these items:
- 3 tablespoons milk
- 1 tablespoon olive oil
- 1 tablespoon sugar
- 3 tablespoons flour
- 1 1/2 tablespoons rolled oats
- 1 tablespoon finely chopped pecans, plus more to garnish
- 1/4 teaspoon baking powder
- 1/8 teaspoon salt
- 1/4 teaspoon cinnamon (optional)
- Pinch nutmeg (optional)
- 1 tablespoon Nutella or any chocolate-hazelnut spread, plus more to garnish
How to Make Oatmeal Nutella Mug Cake Step-by-Step
- Step 1: In a 12-ounce (or larger) mug, whisk together the milk, olive oil, and sugar until well combined and smooth.
- Step 2: Whisk in the flour until the batter is smooth. Then stir in the rolled oats, finely chopped pecans, baking powder, salt, and optional spices like cinnamon and nutmeg if using.
- Step 3: Place a tablespoon of Nutella on top of the batter and gently push it down so it becomes partially submerged in the cake mixture.
- Step 4: Microwave on HIGH for 30 seconds initially. Then continue microwaving in 15-second bursts, checking after each, until the top looks dry, cooked through, and springs back when lightly pressed with a finger. Depending on your microwave power, this will take about 70 to 90 seconds total.
- Step 5: Let the mug cake stand for at least 5 minutes before eating, as the cake and Nutella center will be hot. For extra indulgence, top with additional Nutella or chopped pecans before serving.
