This Keto lemon poppy seed mug cake makes a perfect topper for any meal, and you won’t even have to start it until everybody is done eating.

Okay, in all honesty, a mug cake is not as brilliant as a full-blown birthday cake or anything. But, what a mug cake offers is something else entirely. A mug cake can be thrown together on a whim to help satisfy those instant cravings. It literally takes a few minutes to put together.

The other great thing about mug cakes versus a regular cake is that they are often lighter and easier to eat. Basically, you can eat the whole serving of mug cake and not have to feel comatose after.

Cooking Up Your Mug Cake

What could be sweeter than having a cake done in a matter of a minute or two? Mug cakes are ideal because they can be cooked in a microwave and be done in under three minutes.

However, it is important to check the cake and make certain that it is not raw. If you believe the cake is cooked the whole way through poke a toothpick in the center if the pick comes out clean the cake is done if there is any raw batter try cooking for another 20-30 seconds.
