Cinnamon Keto Apple Crisp in a Mug (Easy Keto Dessert)

By Bree

Sometimes when I’m in the mood for apple pie but not keen on making a big old mess in the kitchen, I make this keto apple crisp in a mug instead. I actually find myself making this more often now because it’s such a warm and comforting dessert, yet still very easy to make.

Can You Bake Apple Crisp in a Jar?

While mug dessert recipes are incredibly versatile, the type of cook achieved with a microwave is unique. If you were to attempt this same recipe but baked it instead of microwaved it, you would have to alter the recipe and the baking time.

How to Avoid Flat or Dry Mug Apple Crisps

Sometimes, mug apple crispd don’t turn out exactly as you envisioned the first time you make them… and that’s okay! Here are some tips to help you avoid flat or dry mug apple crisps:

  • Follow the recipe exactly. Before making any tweaks, make sure to try the recipe as stated, without changes, at least once. Once you have this baseline, you can tweak the recipe if needed.
  • Check the wattage of your microwave. Generally, the higher the wattage, the faster the cooking time. If you’re using a low-powered microwave, you may need to leave it in for another 15 to 30 seconds. If the apple crisp is undercooked, it may not rise properly.
  • Don’t skimp on the moisture. With recipes that contain coconut flour, it’s better to put a little too much than too little of the liquid ingredients. Coconut flour needs a lot of moisture, so don’t worry if you’re a teeny bit over on that butter.

  1. So tasty and definitely satisfied my late night craving for apple pie, but a healthier version. Didn’t have nuts so I substituted unsweetened coconut instead.
