Keto Cranberry Mug Cake Directions

In a microwave-safe mug, mix together the cranberries and erythritol.

Microwave for one minute. Remove the cranberry mixture from the mug and set aside. Rinse out the mug.

Mix together the almond flour, coconut flour, baking powder, and erythritol with a fork.

Add the melted butter, beaten egg, milk, and vanilla. Stir until well combined.

Add a Tablespoon of the cranberry sauce and gently fold into the batter.

Microwave for one minute or until the top is cooked through and a toothpick inserted in the center comes out clean.

Mix together the powdered erythritol and water to create a glaze and drizzle over the top of the mug cake.

Top with the remaining cranberry sauce, juice, and sprinkle with additional erythritol if desired. Serve warm.

Frequently Asked Questions

Should I use cooking spray in the mug?

The butter in this cranberry mug cake recipe works well enough to skip the cooking spray. The cake pulls away nicely from the mug.

What size mugs do you use?

The mugs pictured are 8 ounce tea cups. However, this is strictly because they look nice in pictures. You can use whatever size mug you have as long as it's microwave-safe.

Can I use frozen cranberries?

Yes, you can use frozen cranberries in this mug cake recipe. Frozen cranberries will create liquid as they cook in the microwave. No need to drain it, though, as it makes a tasty syrup to add to the top at the end.

What kind of low-carb milk to use?

I like unsweetened Milkadamia macadamia milk. You can use almond milk, coconut milk, or heavy cream, as well.
