Ingredients

All-Purpose Flour makes the base of this delicious mug cake. You can use half all-purpose flour and half whole wheat flour for a healthier cake.
You can also use gluten-free flour like almond flour or coconut flour for a gluten-free cake.
Blueberries – Use fresh or frozen blueberries. If using frozen berries, then add them directly into the batter. There is no need to thaw them.
Others – You will also need baking powder, granulated sugar, milk, unsalted melted butter, and vanilla extract.
You can replace granulated sugar with coconut sugar or dark brown sugar for a healthier version of this muffin.
Replace butter with coconut oil and dairy milk with any plant-based milk to make a vegan mug cake.
Variations – To make a variation of this blueberry mug cake, you can add a few other ingredients along with blueberries to the batter. Here are some options.
- Other berries like raspberries, strawberries, and cranberries
- Chocolate chips
- M&M’s
- Sprinkles
- Nuts
- Lemon Zest
You can use honey or maple syrup as sugar substitute.
You will also need tall coffee mugs. My recipe fits perfectly in 14-ounce mugs.
How To Make Blueberry Muffin Mug Cake
In a small bowl, whisk together 4 tablespoon (30 g) all-purpose flour, ¼ teaspoon baking powder, and 2 and ½ teaspoon granulated sugar until completely combined.
Note – I use raw light brown sugar in my kitchen, but you can definitely use white granulated sugar as well.
Tip – You can mix the ingredients directly in the mug but I personally feel that mixing in a bowl is easier and more uniform.

Add 3 tablespoon (45ml) milk, 2 tablespoon unsalted butter (melted and cooled), and ¼ teaspoon vanilla extract to the bowl and whisk to make a smooth batter.

Fold in 10-12 blueberries and pour the batter into a 14-ounce microwave-safe mug.
Tip – To check if the mug is 14 oz, pour 1.75 cups of water into it. If the water fits, the mug is the right size to bake the cake.


Microwave on high for 1-½ to 2 minutes, or until the batter is set.
Note – The time of cooking may vary because the microwave power varies in strength. Start with baking the cake for 1 and ½ minutes and then increase the time in increments of 30 seconds.
Remove the mug from the microwave and let it rest for a minute.
Top the blueberry mug muffin with a scoop of ice cream or a sprinkle of powdered sugar and serve warm.

Pro Tips By Neha
Try to make the cake in a mug with straight sides. It will help the cake to cook evenly and rise without overflowing the cup.
You can also divide the batter into two smaller mugs to make a smaller quantity.
Place the cup in the microwave as soon as you add the batter to the mug so that the blueberries don’t sink in at the bottom.
Frequently Asked Questions
To make a vegan version of this cake, replace regular milk with any plant-based milk like rice milk, almond milk, oat milk, soy milk, or coconut milk and butter with vegan butter, coconut oil, or light olive oil.
To make this cake healthier, replace all-purpose flour with whole wheat flour and granulated sugar with organic raw sugar. Butter can also be replaced with light olive oil.
Yes, use an oven-proof mug and bake in a preheated oven at 350°F (180°C) for 15 – 25 minutes, or until a toothpick inserted into the center comes out clean.
Serving Suggestions
Serve blueberry mug cake as a quick dessert on its own or top it with a scoop of vanilla ice cream or whipped cream.
You can also enjoy it as an afternoon snack or whenever the sweet craving sets in.
Storage Suggestion
Made an extra mug? Store it in the fridge for about a day or two.
