- 2 tbsp granulated sugar (or coconut sugar)
- ¼ tsp baking powder
- ¼ tsp cinnamon (plus extra for topping)
- Pinch of salt
- 3 tbsp milk (any kind—dairy, almond, oat)
- 1 tbsp melted butter or oil (vegetable, coconut, or melted vegan butter)
- ¼ tsp vanilla extract
For the Cinnamon Sugar Swirl (Optional but Recommended!):
- 1 tsp sugar
- ¼ tsp cinnamon
Topping Ideas:
- Vanilla ice cream (melts into a creamy sauce!)
- Whipped cream
- Caramel or chocolate drizzle
- Chopped nuts or extra cinnamon sprinkle
Step-by-Step Instructions
1. Mix the Dry Ingredients
In a 12-oz microwave-safe mug, whisk together:
- Flour
- Sugar
- Baking powder
- Cinnamon
- Salt
2. Add the Wet Ingredients
Stir in:
- Milk
- Melted butter/oil
- Vanilla
Mix until just combined (a few lumps are okay—don’t overmix!).
3. Create the Cinnamon Swirl (Optional)
In a small bowl, mix 1 tsp sugar + ¼ tsp cinnamon. Sprinkle over the batter and use a knife to swirl lightly.
4. Microwave
Cook on high for 60-90 seconds (start with 60; cake is done when the top springs back lightly).
5. Top & Enjoy!
Let cool for 1 minute, then add your favorite toppings and dig in!
Why This Recipe Works
1. The Perfect Texture
The right ratio of flour, baking powder, and liquid ensures a fluffy (not rubbery) mug cake.
2. Bold Cinnamon Flavor
Unlike bland mug cakes, this one packs a double dose of cinnamon—in the batter and as a swirl.
3. No Eggs Needed
The butter and milk provide enough richness without requiring eggs.
Tips for the Best Mug Cake
🔹 Use a large enough mug – Prevents overflow (a 12-oz mug is ideal).
🔹 Don’t overmix – Stir until just combined for a tender crumb.
🔹 Adjust cook time – Microwaves vary; stop at 60 seconds and check.
🔹 Add mix-ins – Try chocolate chips, apple chunks, or pecans.
Variations to Try
🍎 Apple Cinnamon – Fold in diced apples + a dash of nutmeg.
🍫 Chocolate Chip – Add 1 tbsp mini chocolate chips to the batter.
☕ Coffee Cinnamon – Replace 1 tbsp milk with cold brew.
🌱 Vegan Version – Use plant-based milk + vegan butter.
Serving Suggestions
