      Made a chocolate one of these with the coconut flour. It overflowed my mug a little but not to much, and with a little heavy cream it was really tasty! I didn’t have any chocolate chips but I didn’t miss them. Thanks again!

      Thank you for this delicious recipe.
      I was craving scones with jam and cream today. I saw the idea to make a strawberry loaf, but wanted to trial it in a mug cake version.
      So I used this vanilla mug cake recipe, & mixed in about a chopped frozen strawberry (I also added a touch more coconut flour to ensure it wasn’t too wet).
      In another bowl I put another chopped frozen strawberry, sprinkled lightly with sweetener, & lightly thawed in the microwave.
      I finally added the cooked mug cake into the bowl with the strawberries, & added a thick dollop of cream on top. Extremely delicious and just what I wanted.
      Thank you again!

      I tripled the batch using coconut flour, baked it in a mini dash bundt pan. Made 4 cakes baked each for 8 minutes. Sprinkled with erythritol icing sugar. very good thought it would be a little dry because of the coconut flour but was quite moist.

      I’m in shock of how good this was! It tasted better than chocolate cake. I did what some other comments had mentioned to do half coconut flour (.5T) and half almond (1.5T) then with pb and cocoa. It was delicious! I added a bit of heavy cream on top and it was heaven.

      Thank you! So delicious – probably the best keto “mug cake” I have tried so far. Confession: I used both cocoa powder and peanut butter, no other adjustments, and it worked just fine. 🙂

      I just made this for the second night in a row. Last night I made the chocolate version but I used cashew flour because I was out of almond. I broke up some sugar free chocolate on top. PIt was really good. Tonight I used the almond flour, cacao , and I broke up a coffee keto cup and microwaved it in. Then put some sugar free chocolate on top. oh my Gosh it was amazing!!

      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!
