Ingredients for Making Keto Mug Cake

Butter: I used salted butter. If you use unsalted butter, add a tiny pinch of salt.
Egg: I recommend a large egg.
Almond Flour: Finely ground is best here. Do not use almond meal.
Sweetener: I used Swerve confectioners; feel free to use whatever sweetener you like.
Baking Powder: Because baking powder uses its potency over time, make sure the baking powder you are using is fresh.
Vanilla Extract: This is optional but recommended. It adds a nice pop of flavor.
Chocolate Chips: Lily’s is my go-to brand. If you go with another sugar-free brand, make sure you read the label to ensure that they are keto-friendly.

Tips & Tricks

Make sure you use a large enough mug or ramekin. The first time I tried this, I used a tiny ramekin, and it created quite the mess in my microwave. I recommend a container that will hold at least 10 ounces of liquid.
The chocolate chips will sink to the bottom a bit, which is why I recommend only stirring half of them in and putting the rest on top. Sometimes I like to invert it and then spread the melted chocolate that has sunk to the bottom on top to create icing.
To switch up the flavor a bit, you can use a Brown Sugar alternative like Surkin Gold or Swerve in place of the Swerve Confectioners.
Since microwaves have different powers, you may need to adjust the cooking time slightly.

Serving Suggestions

I suggest a quick topping of sugar-free whipped cream or ice cream to take flavors to the next level.

The addition of fresh berries, such as raspberries is also an excellent option. Finish it off with a drizzle of sugar-free chocolate syrup, and your chocolate cravings don’t stand a chance!
