    What is a Mug Cake?

    As the name suggests, a mug cake is a miniature cake cooked in a coffee mug in the microwave!

    It’s a perfect serving for one! It’s fast and easy to make too.

    No Flour Mug Cake

    When I first began experimenting to make a successful, good tasting mug cake, most had flour.

    My research indicated gluten-free flour mug cakes weren’t usually successful.

    This version does not contain flour at all. Perfect for those gluten-free or just avoiding flour!

    Chef’s Notes for Making this Mug Cake recipe

    I’ve learned some things over the years of making this mug cake that I’ll share:

    • Results will vary depending on the mug used; both the mug size and the material.
    • The mug in the photos is an 8-ounce (liquid/volume) mug. Each time the cake inflates and settles to a round top over the top of the mug.
    • The mug in the video is also an 8-ounce mug but a heavy, thick diner mug. The cake settled a bit below the rim.
    • The mug cake can be made in any size mug.
    • Different microwaves can impact how much the cake rises.

    Cooking the Mug Cake

    When the mug cake cooks in the microwave, it will rise up much taller than the mug rim.

    You’ll think it’s going to explode but it doesn’t!

    The rising peaks as the cooking concludes.

    As the mug cake cools it will deflate and settle back into the mug for a denser cake as shown in the photos.

    How to Make Peanut Butter Chocolate Mug Cake recipe – Step by Step

    • In a small mixing bowl whisk together with a fork: egg, peanut butter and sugar.
    • Stir in the chocolate chips.
    • Spoon into a microwave safe mug.
    • Microwave on high for 1 minute!
    • Allow to cool slightly before eating.

      Pleasantly surprised. I just knew this would taste like PB scrambled eggs. It was delicious. I made a lower carb version by using sugar free PB and Splenda instead of granulated sugar. I also used Lilly’s sugar free chocolate chips.
