A keto dessert recipe that you can make in only ONE MINUTE! You may feel like you have died and gone to heaven!
I am not a huge dessert person. I am super picky about which desserts I like. A common thing among desserts that I actually like is peanut butter. I love a good Reese's candy cup! This cake mug is very similar!
While following a keto lifestyle, I crave desserts a lot. This is strange for me, because as I mentioned, I am not a huge dessert fan. I think the absence of processed food, fruit, and sugar overall does something to my brain. Then I feel like I have to have dessert!
These days I feel like I rarely have much free time. That tends to be a common theme around most of the people I know. Between work, workouts and the gym, family time, self-care "me-time," there is very little time left for meal prepping.
I have to be really strategic with how I plan my meals. I usually aim for recipes that are quick and easy, but they cannot compromise on taste! I have to enjoy what I am eating.
This chocolate peanut butter mug cake does just the trick with under one minute of cook time! From start to finish the dish is complete in under 10 minutes.
For me, one mug was way too much for one serving. So I divide the mug in half.

Easy Keto Low-Carb Microwave Chocolate Peanut Butter Mug Cake

Ingredients
- 2 tablespoons almond flour
- 1 teaspoon unsweetened cocoa powder
- 2 teaspoons zero cal sweetener I used Swerve
- ¼ teaspoon baking powder
- 2 eggs
- 1 tablespoon natural peanut butter I used Smucker's
- ½ teaspoon vanilla
- 1 tablespoon butter melted
- 1 tablespoon sugar-free chocolate chips I used Lily's. Cacao nibs also work well.
- cooking oil I use a natural olive oil spray
Instructions
- Mix all of the dry ingredients in a medium bowl (almond flour, sweetener, baking powder, unsweetened cocoa powder)
- Combine and mix the wet ingredients (eggs, peanut butter, vanilla, and melted butter) in a separate bowl. The peanut butter (natural) will be thick and runny. You do not have to fully dilute it while stirring. Just stir enough so everything is combined.
- Add the wet ingredients to the bowl with the dry ingredients. Mix well until fully blended.
- Fold in the chocolate chips and stir.
- Spray a mug with cooking oil. Add the mixture to the mug.
- Microwave for 50 seconds to 1 minute. I timed it for 50 seconds because I wanted a really moist cake. With 1 minute it will be slightly more firm, but still moist.

keto + chocolate + peanut butter = yes please! This recipe sounds amazing - a perfect solution to my occasional sweet cravings!
Chloe Harden says
Yummy, decadent indulgence that is perfect for craving solutions! I poured a little swerve-sweetened heavy cream over finished cake to cut the chocolate-richness of it. Thanks for the recipe!

You're welcome!

This is the first mug cake that I actually liked. Topped with whipped cream and it was delish!
Joanne Keas says
I figured every way from Tuesday and could not arrive at your 2 carbs per serving. The almond flour, cocoa powder and natural peanut butter alone would knock that figure out of the park. I used a different brand of stevia sweetened chocolate chips but even so...

You stated what you used differently, that's exactly why your calc differs. You should always rely on your macro calculations.
Kathy Gallivan says
Really wanted to like this, but just cannot. Maybe as a former cake baker, I just don't have reasonable keto expectations.
staysnatched says
Possibly. This is also a microwave cake, so not your typical baked good or recipe.
Laura Garrison says
WOW! This is delicious and such a saver if you have a sweet tooth/carb craving while doing keto. It totally hits the spot. I will definitely make this again.
staysnatched says
The perfect treat!
Spence says
Made this.
Swapped out the peanut butter for hazelnut butter and the sweetener for w tbsp of maple syrup because I'm paleo.
Never had any vanilla so missed that too.
Took 1min 30 in my microwave, but it was awesome.
The first cake like thing I've had in ages.
I'll definitely make this again, thanks for the recipe.
