I've gotta say, I love carrot cake. And I love my microwave. I still don't stand in front of it while it's on, just in case. But it has made my life SO MUCH EASIER. Heating stuff? Check. Defrosting stuff? Check. Mug cakes? Check, check, check!!
I've made a bunch of yummy gluten free mug cakes in my microwave which you MUST try (links are at the end of the post), and even this emergency Keto microwave bread which is awesome for cheese toasties.
Keto carrot cake recipe in a mug
I did consider making a full size low carb carrot cake. But let's face it. Most of the time it's just a couple of people in the house, right? And what happens when you have a whole cake and only two people in the house?
Well, you eat the whole cake! It might take a few days, but eventually it'll be gone. And then you might wish you had only made a carrot cake for 2.
The great thing about this sugar free carrot cake is that you can tuck in literally ten minutes after thinking "Hey, I fancy a carrot cake!" Whether you're following a low carb diet or not, it's just amazing as an afternoon treat or dessert. I can disclose it also makes a very satisfying breakfast 😉
You'll also love to hear that this sugar free carrot cake is just 6.4g net carbs per portion!
How to make Keto carrot cake for two - step by step:
1.) Mix your dry ingredients - almond flour (or almond meal), cinnamon, pumpkin spice/mixed spice, baking powder, powdered erythritol and crushed walnut pieces.
The walnut pieces are optional, but work perfectly taste-wise. You could sub with hazelnuts. If you have time, try dry-roasting them in a pan until gently browned to up the flavour.
2.) Add the wet ingredients - grated carrot, melted butter and double / heavy cream.
Baker's Tip: It's always best if you can weight your ingredients using a digital scale. You don't have to spend $$$ on one. Mine was cheap and cheerful and still works perfectly several years on. If you use cups, make sure you slightly pack the grated carrots.
Your batter should be sticky but soft just like in the image above.
3.) Now you have 2 options. Either fill the carrot cake batter into two well-greased ramekins or microwaveable containers (you could even use cups - this is a mug cake, after all). Or use a larger pyrex bowl and make one larger carrot cake for sharing. I microwaved at 800W for 5 minutes.
I recommend that you bake the cake at 700-800W. This gives the carrot plenty of time to go nice and soft. I have also found that if you microwave on high, the cake rises very quickly and might spill over the top of your ramekin. Trust me, you don't want to clean up that mess.
If you do not have a microwave, do not despair - just bake your cake at 175 Celsius / 350 Fahrenheit for around 15 minutes or until lightly browned on top.
4.) Wait until the cake is slightly cooled, then turn upside down onto a plate and top with delicious cream cheese icing. Alternatively, enjoy straight out of the ramekin or mug!
Tips and tricks for perfect sugar free carrot cake
Which sweetener is best
I used powdered erythritol to sweeten my low carb keto carrot cake. There are also many blends out there, and erythritol / stevia or erythritol / monk fruit blends are especially popular (Lakanto or So Nourished are good options).
Xylitol or allulose will also work, just make sure you powder it first for a smoother result, especially for the cream cheese frosting.
Egg free low carb carrot cake
Amazing news: You CAN make this carrot cake WITHOUT EGG. I discovered this by accident as I FORGOT to add the egg to one of my trial runs. If you choose to omit the egg, add an additional tablespoon of double / heavy cream to achieve a soft consistency.
The cake won't rise as much without egg, and I don't recommend to turn it out onto a plate (this would only work if the cake is fully cooled, but no guarantees there). But if you're happy to enjoy it straight from the ramekin, give it a go - I thought it tasted great.
In the image below you can see the "egg" version on the left and the cake without egg on the right. In case you're wondering about the colour of the left cake, the egg I use have a VERY orange yolk. I might also have had a heavy hand on the cinnamon for the right cake.
Can I use coconut flour instead
Lastly, if you don't like almond flour or are allergic to it, try making the cake with coconut flour. Since coconut flour absorbs more liquid than almond flour, you'll need only half the amount: Use ca 40g / ⅓ cup of coconut flour.
How to store low carb carrot cake
Should you have any leftovers, store them in the fridge for up to 4 days or freeze for up to 3 months.
