How To Make Keto Lemon Mug Cake
This keto lemon mug cake is the easiest recipe to share with your loved one and is made with only 5 ingredients.
Let’s see what you need to create this simple moist, spongy lemon mug cake.
- Almond Flour is an amazing keto flour that creates moist, spongy cakes. If you have a nut allergy, you can replace almond flour with sunflower seed flour.
- Egg – this recipe can’t be made egg-free but eggs are keto-friendly.
- Baking Powder – or half the amount of baking soda.
- Lemon Juice – I used fresh lemon juice.
- Sugar-Free Crystal Sweetener – I love Monk fruit crystal or erythritol but feel free to use xylitol, all with the same ratio. Read my review of keto-friendly sweeteners to find the best ones!
- Lemon Zest – this is optional, of course, but flavorsome and won’t add carbs. I grated some zest from my homegrown lemon. Make sure you use untreated lemon before adding zest to your recipe.
Cooking This Keto Mug Cake
Mug cakes are usually baked for 90 seconds in the microwave.
You must use the high power (800W) of your microwave for perfect baking results.
If you don’t have a microwave, mug cakes can be baked in a small ramekin in the oven.
Preheat the oven to 350°F (180°C) and bake our mug cake for 12-15 minutes.
You know it is cooked when a pick inserted in the center of the mug cake comes out clean or with few to no crumbs on it.
Serving Keto Lemon Mug Cake
Keto lemon mug cake is delicious on its own or topped up with unsweetened coconut yogurt. It’s also delicious, served with a cup of my bulletproof coffee for breakfast.
Coconut yogurt is made of only 2 ingredients: coconut cream and probiotics. It is a delicious dairy-free keto yogurt, and I love the combo of lemon and coconut.
Otherwise, use unsweetened whipped cream or Greek yogurt.
