Ingredients
Butter - I use salted butter when baking. I find it easier to just keep one type of butter in the house. If you do only have unsalted butter that's fine. Just add a teeny tiny pinch of salt.
Coconut flour - The hint of sweetness that comes from coconut flour is delicious! I use almond flour in a lot of my recipes but coconut flour is quite a bit cheaper so it's great to be able to use it on it's own as well. In addition, it is perfect for anyone needing a nut-free option.
Sour cream - Using sour cream adds creaminess and moisture to the cake as it cooks in the microwave.
Egg - The egg is the main binding agent that is used for the rest of the ingredients.
Joy Filled Eats Sweetener - This is my go-to sweetener because it's simple and yummy.
Vanilla - A hint of real vanilla extract is always welcomed.
Baking powder - Adding the baking powder helps to give the cake a boost of fluffiness.
How To Make Keto Coconut Flour Mug Cake
You're going to love how simple keto mug cake recipes are! They're perfect for a fast dessert when you're craving something easy and sweet.

Step Two: Add the mug and mixture into the microwave and heat for 1.5 minutes. The mixture to look like a cake and not be wet.
Variations
Keep in mind that any substitute that you do can change the fact that it's gluten-free or low carb. They may also increase the calorie count and carb count per serving as well.
Make a new flavor - You can easily make a lemon mug cake or a vanilla mug cake by adding extract or even a tad bit of lemon zest. You can even sprinkle in some cocoa powder to give a chocolate flavor and look.
Add berries - We all know that desserts and cakes taste great with fresh berries! Topping with strawberries, blueberries, or other berries creates a light and fresh texture and taste. I would refrain from using frozen fruit as it tends to bleed onto the cake as it thaws.
Top with whipped cream - No matter if you want ice cream or whipped cream, add either (or both!) to the top! Sugar free whipped cream is my favorite!
Add nuts - Looking to add some protein? Adding a scoop of peanut butter or topping with crushed almonds or peanuts can be a great way to accomplish just that. You can even use nut butters such as peanut butter or almond butter for a healthy topping.
Add sugar free chocolate chips - Sprinkling on some sugar free chocolate is a great way to kick up the sweetness while still keeping this dish sugar free. Mix them in to make a keto chocolate mug cake recipe easily!
Coconut oil - Sub in coconut oil for the butter and coconut cream for the sour cream for an easy dairy-free option.
Cinnamon - Add half a teaspoon of cinnamon for an amazing cinnamon keto coconut flour mug cake.
Almond flour - If you'd prefer to use almond flour check out my recipe for an almond flour mug cake.
Common Questions
Can you bake this mug cake in the oven?
Sure. This is about the size of a cupcake so I recommend a similar baking time. It will take about 20-25 minutes at 350.
What other sweeteners can be used in this keto coconut flour mug cake recipe?
Any natural sweetener will work just fine, I have suggestions in the recipe card. I also like using monk fruit sweetener as well.
Why is my mug cake dry?
You may have cooked it too long in the microwave if the texture is dry. As long as you're measuring out the ingredients and paying attention to the cooking time, you should end up with a nice, moist cake for one.

I just made this again, adding a handful of frozen blueberries. Yummy! I like the taste of coconut flour better than almond flour and this is my favorite mug recipe.
