5 Reasons to Always Have This Keto Cake Mix in Your Pantry

When it comes to quick and easy recipes, this keto mug cake mix recipe is one of my all-time favorites for many reasons:

  • It calms my sweet tooth. As someone who goes nuts for anything chocolate flavored, this cake mix always does the trick.
  • It’s a good source of healthy fats. Almond flour contains monounsaturated fats which are good for cardiovascular health.
  • It stays moist. This cake mix always turns out moist mug cakes, even when I accidentally leave it in the microwave a little too long.
  • It’s an excellent cake base. I love topping my mug cakes with my favorite keto spreads or nut butters!
  • It’s ready in a minute. Craving for cake at random hours? This keto mug cake needs just one minute in the microwave, so you can have it anytime the mood strikes you.

How Long Can You Store Homemade Keto Cake Mix?

The great part about this keto cake mix is it can be stored for a few months without spoiling. Personally, I wouldn’t go more than 3-4 months in the freezer and 1-2 months in the pantry.

Almond flour contains a lot of fat, so it tends to go rancid more quickly than say, flour. This is why it’s advisable to keep it in the freezer if you plan to keep it longer than a month or two in the pantry.

Are All Cocoa Powders Keto-friendly?

Not all cocoa powders are keto-friendly. It’s important to check that your cocoa powder is unsweetened as the sweetened variety tends to contain anywhere between 8-15 grams of sugar per ½ cup.

Unsweetened cocoa powder still contains some carbs, most is mostly dietary fiber, which still helps keep the net carb content low.
