KETO PEANUT BUTTER MUG CAKE with almond flour, unsweetened hipped cream and peanut butter drizzle #keto #mugcake #locarb #glutenfree #ketorecipes #sugarfree

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

If you follow me on my Instagram you know I am into a kitchen makeover at the moment and all I have to make my keto recipes is a 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 butters 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’s better to have your carbs from keto friendly food rather than indulging one huge amount of non keto food. As a result, one tablespoon of peanut butter won’t take 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’s snack or breakfast. Keep reading for meal prep and storage but first let’s 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 makes 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 180C (350F) 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 cakes 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 add carbs to the recipe! Your keto toppings options are:

  • unsweetened whipped cream
  • unsweetened whipped coconut cream
  • sour cream
  • cream cheese
  • warm peanut butter – careful this will add a few carbs to the recipe

  • Stir in the sugar free crystal sweetener, baking powder, almond flour and beaten egg (at room temperature), until it forms a cake batter.

Net carbs : 6.7 g per serve (if recipe serve 2 mug cakes)
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 !  
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 silicone (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 serves at 180 C on fan-forced for 10-12 minutes. The baked mug cake will store at room temperature up to 3 days.

    • Yes sure, make sure you are using fresh almond butter jar with oil on top or the mug cake will come out dry. Enjoy, XOXO Carine.

  1. Hi!

    I input all of the ingredients with the products I have via my carb manager app, and this comes to 12 net carbs versus the 8. Why the difference?

    • What count is net carbs total carbs takeaway fiber and usgar alcohol. Carb manage total carb shows sugr alcoho, my nutrition fact doesn’t because they don’t count in the keto equation. I am sure that if you compare net carbs, it will be the same. Enjoy, XOXO Carine

      • my net carbs come to 12net, sugar alcohols not included….

        This is what I get:

        Cal 247
        Net Carbs 12
        Fiber 2.7
        Sugar 1.7
        Protein 9.4
        Fat 21.9

        • I provide nutrition panel as an information, using the ingredients I am using in my country. It is totally possible that your peanut butter brand selected in the app has different net carbs explaining the variation. You should always calculate the net carbs using the exact brand of ingredients you use for precision. Enjoy, XOXO Carine.

  2. Hi Carina, i love your recipes so much. I was trying to make your homemade peanut butter but it seems like my food processor is not strong enough as after nearly half an hour it still didnt go smooth. Could you please tell me which food processor is the best for nut butter ? Thank you..

    • Hello! Thanks so much for trying so many of my recipes it makes me very happy ! Of course, the power of the food processor is what turns nuts into butter and you need a very strong blade nd high power. I use either a Kitchenaid pro blender here. This is my favorite so far because it has a tamper to tackle tough ingredients and turns nuts into nut butter in about 1 minute. Or I use my 11 cups kitchen aid food processor, it takes longer with this one as you need to stop and scrape bowl many times to achieve the right texture. Those tools are expensive at first but long warranty and I don’t nut butter any more so it is very nice ! I hope this is helpful, Enjoy, XOXO Carine.
