Blueberry mug cake recipe
I love single serving treats, like my Single Serving Brownie and Chocolate Banana Mug Cake because if there’s a full-sized cake in front of me, I’m going to eat the whole damn thing.
I’ve come up with a simple solution to blueberry cake: a single-serving, low-calorie blueberry mug cake that’s microwaved in less than 2 minutes. Made with mostly pantry staples, this quick and easy treat has a fluffy crumb and fruity flavor, similar to blueberry muffins or sponge cake. It’s the perfect snack or dessert to satisfy your cravings in no time!
Featured Review
I am hooked on mug cakes. Living by myself I find it difficult to make small portions and am not a fan of leftovers. I was wasting a lot because I would put them in the fridge for too long then have to throw them out. Thank you for the recipes. I am having fun trying different ones. Esther

Fresh or Frozen Blueberries
I’m a gardener, so of course I’m going to tell you fresh blueberries are the best—but frozen blueberries work great in this mug cake too! Fresh berries give the cake a bright, juicy flavor and hold their shape nicely, while frozen ones melt into the batter a bit more, creating little bursts of blueberry throughout the cake. If you’re using frozen blueberries, there’s no need to thaw them first—just toss them in frozen and microwave as directed.
How to make blueberry cake in the microwave
If you can stir and operate the microwave, you can make blueberry mug cakes. You’re going to love how easy this is! Here’s how it’s done:
In a microwave-safe mug or ramekin , mix the flour, sugar, baking powder, salt, milk, butter, and vanilla together until just combined. Try not to overmix.

Gently fold the blueberries into the batter.

Microwave the cake for 1 minute. If the mug cake has risen and looks like a real baked cake, it’s ready to eat. If not, microwave it for 10 more seconds. Microwaves vary in strength. These cakes will take between 60 and 90 seconds to cook.

Carefully remove the mug from the microwave and let it cool for 1 minute. Grab a spoon and enjoy your blueberry mug cake!

Storing Leftovers
A blueberry mug cake is basically a solo party in a cup—so leftovers? Highly suspicious. But hey, maybe you got full, got distracted, or made two by accident (no judgment!). If you do end up with leftovers, just pop the cake out of the mug, wrap it in plastic wrap or stash it in an airtight container, and stick it in the fridge. It’ll keep for 1 to 2 days… if it lasts that long without you sneaking bites.
