Rich and moist keto peanut butter chocolate chip mug cake that will instantly bring a smile to your face and curb any sugar cravings you may have had. This healthy peanut butter mug cake is the perfect single serve keto dessert to enjoy after dinner.

Mug cakes are a huge favorite of mine. They are quick to make, only require a few simple ingredients and are hard to mess up. This keto mug cake without flour is no different.

All you need is 2 minutes, 5 common ingredients and one mug/bowl to make this keto single serve dessert. It’s got the consistency of a regular cake so you get the feeling of eating real cake, but without any of the guilt and carbs.

Can you eat peanut butter on keto?

Peanut butter is high in fats and low in net carbs but you need to make sure you use the right kind of PB. Only use jarred peanut butter where the only ingredient is 100% peanuts and no added sugars, salt or oils.

What is the consistency of this peanut butter cake?

Peanut butter makes this mug cake extremely moist and fluffy. It’s got the consistency of a regular cake and won’t taste dry at all.

How many carbs are in this mug cake?

This mug cake contains 13 g carbs and 6 g net carbs which is quite high for a keto dessert. That is why I recommend you only have this once in a while. To cut down the number of carbs, skip the chocolate chips and that will bring the carb count way down to 7.5 g and 4.5 g net carbs.

Flourless peanut butter mug cake shopping list

• Peanut Butter –  I use this brand as it contains just peanuts, no added sugars, salt or oils. Creamy peanut butter is best for this recipe
• Sweetener – Use any sweetener you have that measures like sugar. I use Erythritol
• Egg – At room temperature
• Baking powder
• Dark Chocolate Baking Chips – I use these which contain 3 g net carbs per 1 tbsp serving. If you can’t find Lily’s or just want to go for a cheaper option, you can also just cut up any dark chocolate bar with 80% or more cocoa content into small bits and use that instead. I like to use Lindt 85% chocolate.

Notes

Make sure you mix everything together really well so it bakes evenly.

Use a mug/ramekin just a little bit bigger than your cake mix as it will raise in the microwave.

This mug cake is not very sweet, if you like it sweeter, increase the amount of your sugar substitute to up to 3 tbsp.

Serve straight out of the microwave as it tastes best when it's freshly made.

Sugar-free ice cream or keto whipped cream makes a great topping for this mug cake.
