How to make Cinnamon Crumble Mug Cake
Make the cake base
- Step 1
In a 14-oz microwave-safe mug, whisk together flour, baking powder, sugar, salt, and cinnamon (if using).
Add wet ingredients
- Step 1
Stir in milk, oil (or melted butter), and vanilla. Mix until smooth and lump-free, scraping the sides and bottom of the mug.
Make the crumble topping
- Step 1
In a small bowl, combine brown sugar, flour, butter, and cinnamon. Mix with a fork until the texture is crumbly and sandy.
Assemble
- Step 1
Sprinkle the crumble evenly over the cake batter — do not mix it in.
Microwave
- Step 1
Cook on HIGH (950 W) for 80–100 seconds, or until the cake rises and the top looks set but still soft. Check at 80 seconds as microwaves vary.
Cool and serve
- Step 1
Let it cool for 1 minute to allow the crumble to crisp slightly.
Enjoy
- Step 1
Drizzle with icing, honey, or top with whipped cream or vanilla yogurt.
