Did we just become keto mug cake best friends?!
I think so! And I think you'll agree too once you try this low carb peanut butter mug cake recipe.
What's the consistency of this mug cake like?
The craziest thing about this keto mug cake is how spot on the cake consistency of it is, and there's not even any flour in the recipe. Like seriously, it's soft, spongy, light, fluffy, and moist. And, the same thing can't be said for most mug cakes, let alone, low carb keto mug cakes.
Keto Mug Cake Pro-Tips
Mug cake recipes are easily one of the most sensitive kinds of recipes you can make. That's because a mug cake can go from delicious, to as hard as a brick - and inedible - in just 10-15 seconds. So, if you want the most delicious results possible for your keto mug cake, keep these next tips in mind.
I highly, highly, HIGHLY recommend undercooking your keto mug cake just slightly. If it's a little too under done, you can always pop in back in the microwave for 5-10 more seconds. Doing this will ensure you achieve the perfect cake consistency from your mug cake. Once a mug cake is overcooked, there's no turning back guys.
My only other pro-tip for this mug cake is to make sure you use "runny" smooth peanut butter. If your peanut butter is on the thicker, clumpy side, put it into the microwave - inside a microwave safe dish of course - for about 15 seconds. It's important to do this, because it will help you mix the ingredients into a batter easier.
How To Make A Keto Peanut Butter Mug Cake
Keto Mug Cake Grocery List & Essentials
- First and foremost, use a food scale - like this one - to make sure you're accurately weighing out all the ingredients.
- Also, keep the carbs and calories as low as possible, use a erythritol sugar substitute to sweeten your mug cake.
- Make sure you go with a Smooth Natural No Sugar Added Peanut Butter for your mug cake.
- Use a ramekin instead of a mug. Mug cakes always turn out better in ramekins.

This really was the best low carb mug cake I've ever made. Thanks for sharing!
So good! I had a carb craving and this hit the spot! Thank you!
Oh my goodness! I don't like mug cakes, at all, but this one is actually really good! I made some keto whipped cream in my NutriBullet to top it off and had a delicious treat in less than two minutes! Definitely satisfies my sweet tooth and peanut butter craving.
Just started Keto and I love this mug. I only used 1 packet of stevia and i used Almond butter, it’s good. It totally satisfies my craving for bread.
THIS WAS DA BOMB!!!! I didn't even put the sweetener in it... and decided to put a little vanilla and a sprinkle of pink salt... Thank you!!
This was delish!! Thank you!
This was the best! It was so moist. Hard to believe it was low carb. I did add a few sugar free choc chips. Thank you
Great consistency and texture. I added sugar-free chocolate chips.
Me too. I add a few chocolate chips and nuts.
This was truly delicious & the texture was just like a delicious cake. Thanks for sharing. As one of the other commentators said..... the best mug cake I’ve ever tried.
Super yum! I used Natural chunky peanut butter room temp and a teaspoon of cocoa then once cooked cut out a small slice and poured a little 35 cream in the bottom to be soaked up in the cake. Sooo easy and exactly the consistency of a cake.
Best mug cake ever! Thank you!
This was really yummy! Thank you for sharing your recipes!!!
Absolutely delicious and quick thank you
Easy, quick, delicious and filling thanks!
Made this for my husband's birthday. He loves peanut butter. He loved this. Delicious.
Best Mug Cake Ever! I am not even a fan of mug cakes but this one is the peanut butter bomb! I love it! So easy to make and for an extra treat I sprinkle a few Lily’s semi sweet chocolate chips on top Right after the microwave and they melt oh so gooey and drip in every bite! Thanks for your recipes Joe you never disappoint!
Amazing!!!
I make this all the time now. Especially on mornings when I am in a rush. Love it so much. It holds me over until lunch really well.
I’ve been making this for awhile now. I love it. Sometimes when I need a little more to
hold me over I add an extra egg. It still turns out great!
The recipe is perfect and it tastes delicious. I would recommend not eating it at once since it’s high in calories. Thank you so much for sharing your recipes.
Thank you! Thank you! Thank you! I make so many of your wonderful keto recipes, but this one is a favorite and I make it at least twice a week. I split the recipe into 2 servings because I find it really filling. I slice each little cake in half and add a little layer of a quick homemade berry compote (just whatever berries i have on hand with some erythritol and xantham gum) so, it's a deeeelicious PB&J cake!! YUMMM!!! It really helps me stick to Keto and satisfy my sweet tooth while I continue to effortlessly lose weight. (This from a woman who ate 2 donuts a day, every day, for most of my life)
