I remember the first time I made a single-serve vanilla mug cake with milk. I was tired after a long day, craving something sweet but not wanting to spend hours baking. The microwave became my friend, and in just a few minutes, I had a warm, comforting treat. That tiny cake felt like a hug in a mug and from that day, I knew this recipe had to be in my collection.
The beauty of this single-serve vanilla mug cake with milk is its simplicity. You only need a few ingredients, most of which are pantry staples, and the cake is ready in under five minutes. It’s perfect for late-night cravings, a quick breakfast treat, or whenever you need a small dose of homemade sweetness without making a whole cake.
Every time I make this mug cake, I think about my childhood, standing on a stool in my tiny kitchen, helping my mom bake simple desserts that made our home smell like happiness. That’s why this recipe is more than just flour and sugar — it’s about comfort, joy, and the little moments that bring us together.

Why I Love Making This Recipe
There’s something magical about creating a dessert that’s just for you, yet still feels indulgent. I love making this single-serve vanilla mug cake with milk because:
- It’s incredibly fast. No preheating the oven, no waiting for layers to bake. Just mix, microwave, and enjoy.

Ingredients & Little Kitchen Secrets
Here’s what you’ll need for one perfect single-serve vanilla mug cake with milk:
- 4 tbsp all-purpose flour
- 2 tbsp granulated sugar
- 1/4 tsp baking powder
- A pinch of salt
- 3 tbsp milk (whole milk gives the best flavor)
- 1 tbsp vegetable oil (or melted butter)
- 1/2 tsp pure vanilla extract
- Optional: chocolate chips, sprinkles, or a pinch of cinnamon for extra love
Little kitchen secrets:
- Use fresh baking powder it makes the mug cake rise beautifully.
- Mix the ingredients gently; overmixing can make the cake dense.
- For extra fluffiness, let the batter sit for 30 seconds before microwaving.
How I Make It, Step by Step
- Combine dry ingredients – In a small bowl, I whisk together 4 tablespoons of flour, 2 tablespoons of sugar, 1/4 teaspoon of baking powder, and a pinch of salt. This ensures the rising agent is evenly distributed.
- Add the wet ingredients – I pour in 3 tablespoons of milk, 1 tablespoon of oil, and 1/2 teaspoon of vanilla extract. I mix gently with a fork until smooth and lump-free.
- Optional add-ins – Sometimes, I fold in a few chocolate chips or a sprinkle of cinnamon to give it a personal touch.
- Transfer to a mug – I use a 12-ounce microwave-safe mug and lightly grease it with butter or oil. Then, I pour in the batter, spreading it evenly.
- Microwave carefully – I microwave on high for 1 minute 20 seconds. Microwaves vary, so I check after 1 minute and add 10-second intervals if needed. The top should spring back when touched lightly.
- Cool slightly – I let the mug cake sit for 2 minutes before digging in. This prevents it from being too hot and allows the flavors to settle.

How I Serve It at Home
I love serving this single-serve vanilla mug cake with milk in the same mug I baked it in. It feels cozy and effortless. Here are some of my favorite ways:
- Drizzle with chocolate syrup or caramel for an indulgent treat.
- Add a scoop of vanilla ice cream on top for a dessert twist.
- Sprinkle with powdered sugar or cocoa powder for a simple, elegant look.
- Serve with a warm cup of tea or coffee for a perfect cozy afternoon.
No matter how I serve it, this mug cake always brings smiles and a little spark of happiness.
Storage, Reheating & Make-Ahead Tips
Since this is a single-serve cake, leftovers are rare, but sometimes I make a few ahead. Here’s how I manage it:
- Storing – Cover the mug with plastic wrap and keep in the fridge for up to 24 hours.
- Reheating – Microwave for 20–30 seconds until warm.
- Make-ahead tip – Mix the dry ingredients in a small jar. When craving a cake, just add wet ingredients, stir, and microwave.
This flexibility is why I love this recipe it fits into any schedule, and you always have a little homemade comfort ready.
