Ingredients
Cake Ingredients
- 1 tablespoon unsalted butter, melted
- 2 tablespoons milk
- 1/4 teaspoon vanilla extract
- 3 tablespoons all-purpose flour
- 1 and 1/2 tablespoons light brown sugar
- 1/4 teaspoon ground cinnamon
- Pinch of nutmeg
- 1/8 teaspoon baking powder
- Pinch of salt
- 3 tablespoons peeled and finely chopped apple (Honeycrisp or Granny Smith)
- 1 tablespoon chopped walnuts, optional
Toppings (Optional)
- Scoop of vanilla ice cream
- Drizzle of caramel syrup
- Additional chopped walnuts
Instructions
- Melt Butter: In a microwave-safe mug (8 to 10 ounce size), melt the butter in the microwave until just melted.
- Combine Wet Ingredients: Whisk in the milk and vanilla extract until fully incorporated.
- Mix Dry Ingredients: Add the flour, brown sugar, cinnamon, nutmeg, baking powder, and salt. Whisk everything together until you have a smooth batter.
- Add Fruit and Nuts: Gently fold in the finely chopped apple and walnuts, if using, ensuring even distribution.
- Prepare for Cooking: Smooth the batter into the mug using a spatula or back of a spoon, and clean the edges with a paper towel for even cooking.
- Microwave: Microwave on high for 90 seconds to 2 minutes, adjusting based on microwave power, until the cake rises and looks set but remains moist.
- Cool and Serve: Let the mug cake sit for 1-2 minutes to cool and firm up slightly. Optionally, top with vanilla ice cream, a drizzle of caramel syrup, and more chopped walnuts before enjoying.
Notes
- Use a fresh, crisp apple variety like Honeycrisp or Granny Smith for best texture and flavor.
- Cooking time may vary depending on microwave wattage; check doneness by ensuring the cake is set but still moist.
- Walnuts are optional but add a nice crunch and nutty flavor.
- For a dairy-free version, substitute milk and butter with plant-based alternatives.
- Do not overcook to avoid a dry cake; better to start with less time and add if needed.
