So be ready for this peanut butter mug cake recipe ready in just a few minutes.
Is Peanut Butter Keto?
All-natural peanut butter made with no added sugar is 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 brands include added sugar or added vegetable oils that are not keto.
The best peanut butter to buy should include only one ingredient, peanuts. And perhaps a pinch of salt, but that’s it!
How Many Carbs Are There On Peanut Butter?
One tablespoon of peanut butter made with 100% peanuts contains 2.5g of net carbs.
Depending on your keto daily macros, it may look high, but it’s better to have your carbs from keto-friendly food rather than indulging in one huge amount of non-keto food.
That’s why one tablespoon of peanut butter won’t take you out of ketosis while that bakery muffin will!
This being said, this keto peanut butter mug cake is your safe option to indulge and stay on track.
How To Make Keto Peanut Butter Mug Cake
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 slight 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 the 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. Read my review of keto-friendly sweeteners to learn some more!
- Unsweetened vanilla almond milk – or unsweetened almond milk or unsweetened coconut milk.
Storing Mug Cakes
This recipe makes two mug cakes, and you may want to serve the second mug cake later. If so, I recommend storing half of the uncooked batter in a ramekin.
Film the ramekin with plastic wrap, and store it in the fridge.
The next day, remove the plastic wrap and microwave straight out from the fridge. You may have to microwave for 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 servings at 350°F (180°C) on fan-forced mode for 10-12 minutes.
The baked mug cake will store at room temperature for up to 3 days.
Serving Peanut Butter Mug Cakes
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 is that 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.
