A warm, soft, gluten-free cinnamon roll–style mug cake that cooks in under two minutes in the microwave, with a gooey cinnamon swirl and optional icing.
Ingredients
Mug Cake
- 1/4 cup gluten-free 1:1 flour like King Arthur or Bob’s Red Mill
- 2 tbsp brown sugar
- 1/4 tsp baking powder
- 1/4 tsp cinnamon
- salt pinch
- 1 tbsp melted butter or neutral oil
- 2 tbsp milk any kind, dairy-free works fine
- 1/4 tsp vanilla extract
Cinnamon Swirl
- 1 tsp brown sugar
- 1/4 tsp cinnamon
- 1/2 tsp water
Optional Icing
- 2 tbsp powdered sugar
- 1/2 tsp milk
Instructions
- In a microwave-safe mug, whisk flour, brown sugar, baking powder, cinnamon, and salt.
- Stir in melted butter, milk, and vanilla until you have a smooth batter.
- Mix cinnamon swirl ingredients in a separate cup. Drizzle it over the top of the batter and swirl with a knife.
- Microwave for 50–70 seconds. Start at 50 — it should puff up and be set in the middle.
- Let it cool a minute or two.
- Mix up the optional icing and drizzle on top, or eat it straight from the mug as-is.
