When I feel like treating myself, which is often, I will usually jump for something savory, like this queso (yes, this sauce often hangs out in my fridge, we are addicted) or homemade popcorn. I'm not looking for dessert very often. BUT. When I want something sweet, then I wanted it yesterday.
And this mug cake is perfect for these sweet cravings. Made with simple ingredients that are often already in the house, you can just mix everything together in a coffee mug, microwave and get your dessert fix without any fuss.

Tips when making this lemon blueberry mug cake
- I tested this recipe with the white whole wheat flour from King Arthur Flour, but regular flour should work too.
- When making this cake for the first time, you might need to experiment a bit. It all depends on the strength of your microwave. Start by cooking the batter for 2 minutes, then add 10 seconds at the time until its done. Do not overcook though, or your cake will get dry or hard.
- When you make the cake, it will rise quite a bit before it sinks back into the cup. So, you need a big enough mug to support this (at least 2 cups or 16oz).
- I also recommend to place the mug on a plate or paper towel in the microwave when cooking to catch any spills if there are any.
- If you would love a more intense lemon flavor, then add extra lemon zest to the batter (about ¼-1/2 tsp).
