    Chocolate Collagen Mug Cake (Paleo, Nut Free)

    Published: Apr 7, 2020 · by Katie

    Jump to Recipe·Print Recipe

    They say you shouldn't eat cake for breakfast... But, this low carb Chocolate Collagen Mug Cake is healthy enough to be eaten at any meal!  This mug cake recipe is ridiculously easy to make!  Just throw all the ingredients together in one bowl and bake in the microwave.  In addition, this recipe is gluten free, Paleo, Keto, dairy free and made with just 7 ingredients.

    My collection of mug cake recipes is lacking...considering the amount of mug cakes I eat.  Which, if I'm being honest is my breakfast 95% of the time.

    Why do I like mug cakes?  Well, first off, who wouldn't want to eat cake for breakfast!?  Haha!  But in all truth, I love mug cakes because they are EASY!

    I don't get much time to myself these days (with 3 little kids and all).  So a quick, simple breakfast is what I need.  Plus, I'm able to get a healthy dose of protein, fat and carbs all in one nice little package.

    Another great thing about mug cakes?  The toppings.  I don't use frosting like you would on a "normal" cake, but instead choose healthy, low sugar options.

    Healthy Mug Cake Toppings

    Some of my favorite mug cake toppings include:

    • dairy free yogurt
    • nut butter, seed butter or coconut butter
    • nuts and seeds
    • fruit - frozen, fresh or even freeze dried
    • homemade jam
    • cacao nibs
    • extra dark chocolate chips
    • bee pollen
    • goji berries

    My hunger level dictates the toppings I choose.  For instance, days that I'm starving, I may load up on almond butter and blueberries.  Days I'm not as hungry I'll be more conservative with my portions and maybe stick to fruit and a dollop of yogurt.

    Ingredients in Chocolate Collagen Mug Cake

    This Paleo mug cake recipe is made with 7 ingredients:

    • cocoa powder
    • collagen
    • ground flax
    • coconut flour
    • baking powder
    • egg
    • water

    I used the chocolate collagen from Ancient Nutrition, which is sweetened with stevia.  Because of this, no sweetener was needed - perfect for a healthy keto collagen mug cake.  However, you may want to add a sweetener such as maple syrup or monk fruit if the collagen you are using is unsweetened.

      Hi there,
      Would a chocolate protein powder work as a substitute for the collagen powder in this recipe?

        Protein powder should work as a replacement.

      Can this be done without the flax seed?

        You can omit the flax seed, but it changes the texture.

      I can’t understand a using a microwave in a keto or paleo lifestyle? How is it healthy?
      Will have to give it a try in an air fryer

        There actually isn't any hard evidence that microwaves are unhealthy. Besides, you don't have to use one if you don't want to! xo

      I used plain fish collagen and added two stevia packets, and a pinch of salt, it was still bitter, but I enjoy the taste. And I love the texture so cakey and perfect with a cup of coffee or tea😍Thank you!

      I ran out of flaxseed and did 1 tbsp of coconut oil and added 3 tbsp of water. I am not sure how the original texture was supposed to be but it still came out great! Thank you for sharing your recipe!

      I’ve tried a lot of mug cakes, this was delicious. I used unflavored collagen so I added 1tbsp of lakanto and used almond milk in stead of water and added Lilly’s chocolate chips. Delicious!

      Yum! I added chocolate chips and vanilla bean paste and it was delicious. Also, baking in the oven gave a lava cake like texture.
