In a medium-sized bowl, stir together the whole-wheat flour, strawberry protein powder, baking powder, and pinch of salt. Set aside.
In a small, microwave-safe bowl, melt the honey and coconut oil in the microwave for about 30 seconds.
Make a well in the center of the dry ingredients and pour in the melted honey, vanilla Greek yogurt, and unsweetened vanilla almond milk. Stir until smooth and well combined.
Lightly spray a mug with cooking spray and pour the batter in. Microwave for 1 minute and 10 seconds, keeping a close watch to ensure it doesn't overflow.
Let cool for 1 minute and stir together your choice of topping in a small bowl.
Top with your desired frosting or fresh fruit and enjoy!
