Keto peanut butter mug cake is an easy 60 second almond flour mug cake recipe with a delicious bakery style muffin texture . Plus, it is gluten free and dairy free!

If you follow me on my Instagram you know I am into a kitchen makeover right now and all I have to make my keto recipes is mostly microwave ! So be ready for keto mug cake recipes starting with this delicious low carb peanut butter mug cake.

Is peanut butter keto?

All natural peanut butter made with no added sugar are low carb and keto friendly. The main thing  when you buy peanut butter on a keto diet is to look at the ingredient list. In fact, many peanut butter brand includes added sugar or added vegetables oil that are not keto. The best peanut butter to buy should include only one ingredient, peanuts or eventually a pinch of salt !

How much carbs in peanut butter?

One tablespoon of peanut butter made with 100 % peanuts  contains 2.5 gram net carbs per tablespoon. Depending on your keto daily macro, it may look high but it is better to have your carbs from keto friendly food rather than indulging on huge amount of non keto food. As a result, one tablespoon of peanut butter won’t keep you out of ketosis while that bakery muffin will ! This said, this keto peanut butter mug cake is your safe option to indulge and stay on track.

Keto peanut butter mug cake for two !

This is a recipe for two, that you can share or meal prep for your next day snack or breakfast. Keep reading for meal prep and storage but first let see the ingredients you need to make this simple almond flour mug cake with peanut butter.

• Peanut butter – no added sugar, no added salt
• Coconut oil – I used unrefined coconut oil which has a light coconut flavor. Otherwise use refined coconut flour or butter
• Egg – don’t replace by flax egg, I tried and it doesn’t come out great at all
• Almond flour – thin, blanched or almond meal but the mug cake will come out slightly drier
• Baking powder – or half amount of baking soda if preferred
• Sugar free crystal sweetener – as always I am using Monk fruit stevia blend but erythritol or xylitol will work well too
• Unsweetened vanilla almond milk – or unsweetened almond milk or unsweetened  coconut milk

How to store mug cake?

This recipe serve two mug cakes and you may want to serve the second mug cake later. If so, I recommend you store half of the uncooked batter in a ramekin. Film the ramekin with a plastic wrap, store in the fridge. The next day, remove the plastic wrap, microwave straight out from the fridge. You may have to microwave slightly longer, an extra 20 seconds may be needed to achieve the same texture as the batter is very cold. Another option is to bake both serve at 180 C on fan-forced for 10-12 minutes. The baked mug cake will store at room temperature up to 3 days.

How to serve my mug cake ?

Mug cake can be dry on their own and I always recommend a dollop of cream on top. The good thing with that extra tablespoon of cream: it doesn’t adds carbs to the addition ! Your cream keto toppings options are:

• unsweetened whipped cream
• unsweetened whipped coconut cream
• sour cream
• cream cheese
• warm peanut butter – careful this will adds-on few carbs to the recipe

Net carbs : 6.7 g per serve.

Too much for your macro ? Split the recipe in 3 serve to make smaller mug cakes and gets only 4.5 g net carbs per serve ! If you divide the batter by 3, each mug cake are smaller and bake faster, only 45 sec in the microwave per mug cake. 

Storage:

This is a recipe for 2 mug cakes (or 3 to decrease net carbs if needed, see note above). I recommend you the extra batter in the fridge, in single microwave proof mug/ramekin. Wrap the ramekin with a piece of silicon (or plastic wrap to avoid the top to dry). Store up to 24 h in the fridge. The next day, remove the plastic wrap, microwave straight out from the fridge. You may have to microwave slightly longer, an extra 10-20 seconds may be needed to achieve the same texture as the batter is very cold. Another option is to bake both serve at 180 C on fan-forced for 10-12 minutes. The baked mug cake will store at room temperature up to 3 days.
