Why you’ll love this recipe
There’s so much to love about this single-serving cake in a mug:
- It’s a sweet, chocolaty, decadent little dessert
- If a rich, moist texture is what you like, this is for you!
- Quick and easy treats are the best…
- It’s healthy and ready in about 5 minutes
- This amazing recipe is sugar-free, gluten-free, low-FODMAP and low-carb
- Almond flour – this is a versatile, keto and FODMAP-friendly flour
- Coconut flour or whey protein powder – these add a lovely texture. If you’re following a low-FODMAP diet, use whey protein powder instead of coconut flour. You can also replace these with more almond flour in a 2:1 ratio. I really like making a protein mug cake using vanilla whey protein powder here. TIP: Use whey protein powder, not isolate. Whey protein isolate will work, but the cake will be more heavy and dense.
- Mayonnaise – I love using mayonnaise in keto cakes! It helps keep them tender and moist. If you don’t want to use mayo, you can always replace it with butter or olive oil (which makes a delicious, tender cake!).
- Egg – this binds everything together and adds a fluffy texture.
- Cacao powder – I love the health benefits of raw cacao powder. You can also use unsweetened cocoa powder for a rich, chocolatey flavor.
- Sweetener – Use your favorite sweetener of choice. I like to use a 50/50 blend of powdered stevia and monkfruit.
- Baking powder – helps make this cake rise
- Heavy whipping cream, half and half or nut milk – to thin out the batter just a bit
- Vanilla extract – this always adds a depth of flavor
- Butter or oil – used to grease the ramekin or mug
You can make this fudgy chocolate delight in a ramekin (which is my favorite way to make it, btw), in a mason jar or in a coffee cup – it’s totally up to you, just as long as it’s microwave safe.
If you want to make two smaller cakes, no worries – this doesn’t have to be just a single serving. These perfect little keto and low-FODMAP desserts can be split into two small cappuccino cups or two small ramekins. It’s truly a low-carb ‘cup’ cake that will satisfy even the most die hard sweet tooth while delivering that perfect cakey texture. It’s a recipe for chocolate lovers (like me!)!
This easy mug cake recipe calls for just a few ingredients: almond flour, coconut flour, baking powder, cream or nut milk, mayonnaise, cacao (or cocoa) powder and sweetener.
Here’s how this sweet treat comes together:
- Grease a microwave safe cup (or cups) or ramekin
- In a small bowl, mix the ingredients
- Pour the batter
- Cook for 60 seconds in the microwave on high
- Done. You now have your own keto bakery.
TIP: After removing from the microwave, the ramekin will be very hot, so be sure to use an oven mitt to transfer to a cooling rack or counter.
What makes this mug recipe different?
Besides this being a sugar-free mug recipe, I have a secret ingredient to making this chocolate cake so soft and fluffy. Well, actually, it’s not really a secret. Bakers have been using mayonnaise in chocolate cake for ages. I got a ‘wild hair’ and tried using mayo instead of using my usual butter and the result was a keeper! It’s like a puffy little keto brownie in a mug.
You certainly don’t have to use mayonnaise. It can easily be replaced with butter, coconut oil or olive oil (chocolate olive oil cake is phenomenal!).
Yes indeedee! This is actually a very healthy mug recipe that uses almond flour and coconut flour instead of wheat.
No – only if you want to. By no means does this have to be a sugar-free cake. You don’t have to follow a keto lifestyle or a keto diet to enjoy a perfect mug recipe. I like to use a combination of stevia and monkfruit sweetener, but you can use any sweetener you please: regular sugar, coconut sugar, maple sugar, etc. They all work great!
It’s a cinch to create a dairy-free mug cake. Simply use plant based milk instead of cream and grease the ramekin with your favorite product, like coconut oil or plant shortening.
I recommend using fine almond flour. Some low carb almond flours use whole almonds (meaning the skins are also ground) which is okay for some dishes, but I find that it doesn’t work as well for baking. Fine, blanched is really the best to use. And, it works exceptionally well in microwave recipes.
After 60 seconds, your fancy treat should be completely set. Microwaves vary, so you may need another 20-30 second to guarantee it’s cooked through. Insert a toothpick in the center. If it comes out clean, you’re set!
While I’ve never made it in an air fryer or oven (yet!), I would guess that 350 degrees Fahrenheit for about 15-20 minutes would work. If your cake has risen and you insert a toothpick in the center and it comes out clean, then it’s done.
You can serve your amazing little quick treats in the mug or ramekin that you cooked them in. Or, wait until they’ve cooled a bit, pop them out, and frost/drench/smother in Keto Whipped Cream and syrup to your hearts content.
