A Keto mug cake can be comfort food, dessert or even breakfast.
The Keto Peanut Butter Mug Cake is a fantastic addition to any part of your day.
What's one of the best parts about this single serving, low carb dessert? Besides being delicious and curbing your carb cravings, it only takes about two minutes to make. You can't do much better than that.
Recipe Tip: Mix PB Coconut Flour & Eggs First
The Keto Peanut Butter Mug Cake recipe seems a little weird at first because there is nothing like flour in it. No almond flour, no coconut flour....
There is such a thing as peanut flour, but to make it requires that they "de-fat" the peanuts so that you can grind them and not end up with peanut butter.
So the peanut butter is both part of the fat and the flour.
What you going to want to do is melt the coconut oil (if it is not liquid) and then vigorously it together with the peanut butter and egg.
Then add the baking powder and erythritol and mix only until it is mixed.
The reason for this is that baking powder starts to react as soon as it gets wet, and if you have the baking powder in for all of the stirring, by the time you get the peanut butter and eggs thoroughly mixed you will also stir out all of the carbon dioxide bubbles, and your mug cake won't rise as much.
Nutrition Tip: Peanut Oil
The oil in peanut butter is the healthy kind, but you should avoid the peanut oil that you buy in a bottle.
What? I know....
You might wonder how that could be and that does seem odd, but there is a huge difference.
The oil in peanut butter is just the oil as it naturally occurs in the peanut.
The peanut oil in the bottle at the store is separated from the rest of the peanut using heat and solvents.
The residue of the solvents then makes the peanut oil smell bad so they add peanut perfume to mask the solvent smell. EWWWW.
Peanut oil that is produced this way is inflammatory and just kind of gross to think of.
I explain more about in my Post about Healthy Fat.
One caveat, you can buy cold pressed peanut oil if you want that flavor, but it's pricey.
Peanuts, Peanut Butter & Keto
At our house we love peanuts and peanut butter.
Brenna and Ada sometimes just eat peanut butter by the scoop, and a small bowl of peanuts is my nightly TV snack.
Peanuts and peanut butter - that is made from just ground peanuts - are not a perfect Keto food like an avocado, but they are pretty close.
The calories in peanuts are 76% from fat, about 17% protein, and about 7% from carbs.
In one tablespoon of peanut there are 1.4 grams of dietary fiber.
And best of all, Peanuts taste great. That is why we use them in tons of recipes like:
