Ingredients
Cake
2 tablespoons of sugar (I like to use brown, I have also tried it with Truvia, which works well)
1 tablespoon of butter
2 tablespoons of Greek yogurt
Dash of vanilla
1/4 teaspoon of cinnamon
Dash of nutmeg
1/4 cup all-purpose flour
1/8 teaspoon of baking powder
Pinch of salt
Topping
1 tablespoon of butter (use cold butter straight from the fridge for the crumbliest topping)
2 tablespoons of flour
1 tablespoons of brown sugar
1/4 teaspoon of cinnamon
Dash of nutmeg
Instructions
Place the butter in a mug. Microwave for 10-15 seconds to soften the butter. Remove from the microwave and stir in all ingredients, except for the flour. Mix until well-combined. Fold the flour in, making sure to not over-mix. Using your spoon gently push the batter together into the bottom of the mug. Set aside.
To make the topping, use your fingers to mix the butter, flour, sugar and spices together to form a crumbly mixture. Add to the top of the cake.
Microwave the cake for 60 seconds (the time may vary depending on your microwave, but it should take anywhere from 50-90 seconds). Serve immediately with milk or coffee.
