- 3 tbsp granulated sugar (divided: 2 tbsp for the batter, 1 tbsp for the cinnamon swirl)
- 2 tbsp unsalted butter, melted
- 2 tbsp milk (any kind works!)
- 1 large egg yolk (save the white for another use)
- 1/4 tsp vanilla extract
- Pinch of salt

- 1 tbsp brown sugar (or granulated sugar if you don’t have brown)
- 1/2 tsp ground cinnamon
Optional Toppings:

- Extra melted butter or caramel drizzle
Step-by-Step Instructions
1. Mix the Dry Ingredients
- In a small bowl, combine 2 tablespoons of granulated sugar, 6 tablespoons of flour, and a pinch of salt.
- In a separate small dish, mix 1 tablespoon of granulated sugar with the brown sugar and cinnamon for the swirl. Set aside.
2. Make the Batter
- In a microwave-safe mug (12–16 oz size), whisk together the melted butter, milk, egg yolk, and vanilla extract until smooth.
- Gradually stir in the dry ingredients until fully combined and no lumps remain. The batter will be thick.
3. Add the Cinnamon Swirl
- Spoon half of the batter into the bottom of the mug.
- Sprinkle the cinnamon-sugar mixture evenly over the batter layer.
- Add the remaining batter on top, spreading it gently to cover the swirl.
