Tips for Making a Keto Mug Cake

• Don’t skimp on the baking powder. A keto mug cake needs a leavening agent, so baking powder is necessary to make your mug cake rise. Otherwise, you may end up with a spongy, flat disk instead of a fluffy, springy cake.
• Use a large mug and don’t fill it more than half to 2/3 full. You’ll avoid a mess and a mug cake that doesn’t set in the middle.
• You can make two servings by splitting your cake mug batter into two ramekins or mugs.
• Always start with the lowest necessary cooking time. You can add a few seconds at a time if needed until your mug cake is firm in the center, but don’t go over one minute. Keep in mind that the cook time may vary depending on the size of your mug and the model of your microwave.
