Now, I know it’s pie day and I’m totally failing on that part. I tried to make a coconut cream pie in the microwave and it just didn’t work out. The crust cooked just fine in the mug, but try to remove it and it completely breaks apart. So, I’ll just give you something that’s just as good!
Just in case you missed out on the previous recipes in this mug cake series, you can check them out:
If you’re a fan of coconut and chocolate, then give this one a try! You can taste the coffee, but not too much. It accents the chocolate extremely well – the coconut coming through as you bite into the flakes and giving you just a hint of textural contrast.

This turned out spectacular! Easy and delicious and *fast*! I added a few drops of coconut flavoring and almond extract to make the flavor profile like an Almond Joy! Will definitely be making this again. Thanks for the great recipe!
Those extract additions sound great! Glad to hear you enjoyed it 🙂
One super recipe! I didn’t use it in a mug but I placed it in a pan. It turned out a great base for my cake 🙂 Thank you.
Amalia, that sounds awesome 🙂 And you’re totally welcome, by the way!
Would it be alright to use Stevia crystals and liquid instead of Erythritol? I don’t live in the USA and it’s not here in Sweden from what I could find. Is there much of a difference between Stevia in all forms or Eyrthritol?
Freja, you should be fine doing that. It always depends on the brand. Some brands of crystallized stevia has fillers included inside, but most are similar. The “filler” process just limits the amount of sweetness it has.
Oh my this was soooo good! I just made this and it was so easy and really turned out great! I left out the stevia and it was plenty sweet for me. I’ve tried to make mug cakes before but it never turned out at all and I always ended up throwing it away. But not this one, I ate it all up, very yummy. Thanks for this recipe!
Glad to hear it Carey! I love me some mug cakes and I’m soon working on some more flavors 🙂
Just whipped this up! It was a delicious snack. Every bit as good as any traditional chocolate cake!
Glad to hear you enjoyed it Daniella!
Can you substitute (or just leave out) the instant coffee crystals? That’s one thing we never buy and I’m not sure I could justify buying them just for this. LOL Well, maybe… 😉 Nah.
You could just leave it out – would be very easy to do 🙂
New to keto (~2months) and have made this twice…REALLY good. I put power 10 on my microwave but it does nothing (1200W). It does come out on High and 45 seconds, but dryer than I’d like. Is there a way to make it moist?
Hey (sorry for the late reply). You could try cooking it slightly longer at a lower power level. Generally you want the top to be pretty sheen with moistness when you take it out.
Can this be made with only coconut flour? I’m
making a smash cake for my almost 1 year old and don’t want to use traditional flour or refined sugar or sugar alcohols. Will the flavor change much if I sub 100% real maple syrup or banana for the sugar alcohol? any suggestions? Also, is this fluffy, or dense? Hopefully it won’t knock me out of keto if I taste it!
It could but you may need to add a little more liquid. Coconut flour will absorb much more than almond flour. Maple syrup will put the carb counts up too far for keto, so it probably wouldn’t be best. Same with the banana (but not for MOST sugar alcohols). This is a little fluffy, but certainly won’t be super fluffy – no keto baked good is, really.
Hope that helps!
Thanks!
It sounds like I will have to play with with the ingredients I have chosen a bit . I really don’t want to use sugar alcohols in a cake for my 1 year old, so I will put the maple syrup and only taste a bit myself to make sure it is good. I have been doing keto myself since June and haven’t been tempted due to always being satisfied from foods. I had a bad first three days though, so I wanted to make sure that tasting this cake wouldn’t make me have to go through that again..
Sounds good – I hope it came out okay for your 1 year old!
I experimented and found a combination that worker perfect! I even stayed in ketosis after tasting! It came out exactly like what I had in mind. I ended up leaving out cocoa because of caffeine, so it was pretty much completely different, but basic ingredients were there. If anyone is interested I can post. Very moist.
Fun keto with my daughter who loves to bake and cook. Kids couldn’t finish it so we had left over mug cake. The next day mug cake was still as good hot or cold. Thank you for all the wonderful recipes.
Glad to hear it! In my house, the mug cake never lasts – but that’s good to know 😀
i don’t have a microwave, can i just make this in a conventional oven? Will it have the same texture? And for how long should i bake it? thanks 🙂
I think you can bake it, but the baking time will be very short. I don’t know exact times, or if it will have the same texture or not. I haven’t tried it yet.
