Instructions
1. In a small bowl, whisk together flour, brown sugar, baking powder, and cinnamon.
2. Add milk, melted butter, and vanilla; stir until smooth.
3. In another bowl, mix softened butter, brown sugar, flour, and cinnamon with a fork until crumbly.
4. Pour batter into a 10–12 oz microwave-safe mug and sprinkle crumb topping evenly over the top.

Notes
Use a straight-sided mug for even rising.
Avoid overmixing — stir just until combined.
Add a pinch of salt to balance the sweetness.
Top with a little Greek yogurt or powdered sugar for an easy finish.
