      Made the vanilla version with half the called for coconut flour (1/2 Tbl) and half the called for almond flour (1 1/2 Tbl) to get a balance of the two options. It came out fluffy and delicious!!! Perfect texture, and it pulled slightly away from the mug so no spray or anything was necessary.

      I used my good old coffee cup to make this. Sprayed it with some coconut oil spray. It did not stick. Mixed everything in the cup for less mess. I also made a Vanilla and almond flavored version of this recipe. My favorite was the chocolate and peanut butter flavored though. Thank you so much for sharing you wonderfully creative cooking creations. I was getting bored with the same old recipes and this one was so simple! Keto ON girl!

      This mug cake recipe is very versatile. I made this a raspberry version using raspberry extract and Lily’s raspberry-vanilla baking chips then a few smashed raspberries. It was delicious!

      I think it’s one of the best recipes I’ve tried………great texture and flavor. I got a little doughnut maker and I think this would work great for that too. You’ve gained a dedicated follower……..thanks so much.

      Yep, these do the trick! I liked the vanilla when made to the recipe, but the next time I made it I added a dash of nutmeg. I liked it with the nutmeg. Thinking about cinnamon.

      This is sooooo amazing! One of the BEST Keto recipes I’ve come across. This mug cake tastes like any other cake but only 3 net carbs! Super simple and quick, too. I treat myself to this cake a few nights a week with some freshly whipped cream and 1/4 cup of berries. I also pack the ingredients with me when I have dinner with friends so I can have dessert with them, too. Thanks for this awesome recipe and helping me stay Keto!

      Wow. I just tried the vanilla version, and it is delicious! My son, who is a stickler for traditional desserts, liked it too. This will be my go to recipe when I crave something sweet! Thank you.
