Equipment

Ingredients

  • 1 Tbsp butter melted, salted
  • 1 Tbsp granulated sugar
  • 3 Tbsp all purpose flour
  • 1/8 tsp salt
  • 1/4 tsp baking powder
  • 1 Tbsp milk or water
  • 1/2 tsp vanilla extract

Streusel Topping

  • 2 tsp brown sugar
  • 1/2 tsp butter softened, salted
  • 1/8 tsp cinnamon

Glaze

  • 1 tsp milk just enough to make a nice drizzling consistency
  • 2 Tbsp powdered sugar
  • 1/2 tsp vanilla

Instructions

  • Grease a microwave-safe mug or a 6 oz. ramekin with butter or non stick cooking spray.
  • In a bowl, combine melted butter, flour, salt, baking powder and milk in a small bowl. Mix to combine.
  • Spoon cake batter into prepared ramekin.
  • In another small bowl combine streusel topping, brown sugar, 1/2 tsp softened butter and cinnamon. Mix to combine. If it is too wet, add some additional sugar.
  • Sprinkle crumb-topping on top of batter and use a knife to gently swirl the topping into the batter. Don’t overmix.
  • Bake in a 350 degree F oven for 12-14 minutes or until cooked through and beginning to pull away from sides or in the microwave for 45 seconds. If not entirely done, microwave for another 15 seconds.
  • In a small bowl, combine powdered sugar and enough milk to make a good drizzling consistency. Drizzle over warm mug coffee cake after removing from oven.

Notes

  1. To make this dairy free, substitute in your favorite non dairy milk and use a mild flavor oil instead of butter.
  2. To make it gluten free, use your favorite cup for cup gluten free flour and then allow batter to sit for 20 minutes or so before baking to help prevent grittiness.
  3. Don't overmix your batter. Mix just until the ingredients are incorporated. Overmixing causes too much gluten to build up and will make your mug coffee cake tough.
  4. It's o.k. if your coffee cake sinks a bit in the middle, it is just from the weight of the streusel topping and just makes it more gooey and delicious!
