Coconut flour mug cake – keto single birthday cake

This keto coconut flour mug cake is the most delicious keto vanilla mug cake with only 4.9g net carb per serve. Plus, it makes a lovely single serve keto birthday cake if you use my keto coconut frosting. Also, the recipe is gluten-free, dairy-free and therefore suitable for anyone on paleo diet too!

We all crave birthday cake at some point, whether it’s your birthday or not, that craving must be fixed right? As always I’m here to tell you that this is ok to have birthday cake on a keto diet. Of course, you need to use the right ingredients to keep things very low carb and  high fat but keep reading and I will guide you through this in a sec!

Coconut flour mug cake – cake cravings fix in 90 seconds

Coconut flour is one of the lowest flour in carbs. Therefore it’s the perfect choice to make keto cakes or breads. It is also a high fiber flour, meaning it absorbs liquid very quickly and that is why you need to measure your flour with precision to ensure a moist keto vanilla mug cake. Let’s see what you need to make this lovely treat:

• Coconut flour – make sure it has no lumps for best result. If so, squeeze the lumps between your finger tips before you measure the flour
• Egg – don’t replace by an egg free option or it will be very crumbly and dry
• Unsweetened almond milk  – I always use Almond Breeze because it doesn’t contain added starch or sugar and the flavor is transparent so it doesn’t change the cake flavor. However, it does add the creaminess you expect from milk, without the dairy or carbs so it is perfect for this
• Coconut cream – I use canned coconut cream, always choose it with more than 30% fat per 100 g for the most delicious creamy texture. Otherwise, if you can’t find it where you live replace by heavy cream
• Sugar free crystal sweetener – I love Monk fruit stevia blend, see here, it’s the best sugar replacement on keto, no carbs and no aftertaste.
• Vanilla stevia drops – or vanilla essence it is up to you or coconut stevia drops if you want to make a keto coconut mug cake
• Baking powder

How to bake keto mug cake?

A keto mug cake is generally baked in the microwave between 60 seconds to 90 seconds. As I divided this recipe in half, I cooked this recipe in 2 separate mugs to assemble a birthday layer cake. Consequently, I only microwaved each mug cake for 60 seconds. The reason why I decreased time is to keep the cake moist and soft. If you intend to microwave the whole batch all at once you can microwave it for 9o seconds. Of course, some of you may not have a microwave and that’s ok. You can bake mug cakes in greased ovenproof ramekins for 8-12 minutes at 180 C (350F). You know the mug cake is ready when the batter is set but still moist.

How to make coconut keto frosting?

The best way to create a single serve keto birthday cake with a mug cake recipe is to bake 2 similar cake layers and assemble them with keto frosting. My favorite keto frosting is dairy free, made of unsweetened coconut yogurt, unsweetened dessicated coconut, powdered erythritol and stevia drops. Actually, pure coconut yoghurt is the best keto yoghurt you can eat! It has no sugar, no dairy meaning no lactose sugar. It’s made of 100% coconut cream and probiotic that is all. I recommend you check the ingredients list of your yoghurt before buying as some brands add starch or sugar!
