    Ways to make mug cakes healthier

    Traditional mug cakes aren’t exactly the healthiest things to consume. They’re laden with sugar and often made with regular flour, so they aren’t very paleo or keto-friendly. Luckily, there are workarounds so you can have the convenience and decadence with less carbs (and guilt).

    Flour or flourless

    Instead of using regular flour, keep your cake gluten-free with alternative, grain-free flours such as:

    Heck, you can even go completely flour-free as well. For example, stick to cocoa powder for a chocolate mug cake, or use eggs to create the cake.

    Egg or eggless

    Eggs help bind the ingredients together and give your cake a moist, gooey texture. But if you follow a vegan lifestyle or prefer no eggs in your cake, increasing your milk by a tablespoon or two gets you a similar texture. Or, there’s also the option of using the full egg or just the egg whites, depending on your preferences.

    Low carb protein mug cake

    Use 1 scoop of your favorite protein powder in any mug cake recipe for the extra nutritional health factor. Try to avoid whey protein powders, which tend to turn mug cakes into rock-solid hockey pucks. If you’re not loyal to any particular type, you may want to try this organic one for texture and taste.

    Now let’s get into the keto mug cake recipes!
