1 Minute COLD BREW Low Carb Mug Cake

Low Carb Cold Brew Mug Cake Recipe
Written by The Protein Chef

Most morning routines consist of ingesting coffee beans in some way, shape, or form…today we add to that arsenal with this Cold Brew Mug Cake. If you want another way to take in your coffee or a great little quick snack that has a boost this recipe is for you and it’s low carb too so lets jump right into it!

To start coat a mug with some non-stick cooking spray and add into it 1 large egg, 2 tablespoons of coconut flour, 1 tablespoon of cocoa powder, 1 scoop of your favorite chocolate Labrada protein powder or change it up with other flavors, 1 tablespoon of sour cream or Greek yogurt (in my opinion sour cream works better for this recipe), 2 ounces of cold brew, 1/2 teaspoon of baking powder, and a little salt.

Go ahead and mix all of those together until smooth. Put your mug in the microwave for around 1 1/2 to 2 minutes depending on how powerful your microwave is.

Yes, this is delicious and YES, it’ll give you a boost. The caffeine content in this if you use a decently concentrated cold brew is around 75-100mg. You could also use regular coffee or espresso if you don’t have cold brew on hand!

  • 1 Large Whole Egg
  • 2 Tablespoons (14g) Coconut Flour
  • 1 Tablespoon (5g) Cocoa Powder
  • 1 Scoop Favorite Flavor Labrada Nutrition Protein Powder
  • 1 Tablespoon (15g) Light/Fat Free Sour Cream or Greek Yogurt
  • 2 Ounces Cold Brew or Coffee/Espresso
  • 1/2 Teaspoon Baking Powder
  • A little Salt

How to make:

  1. Coat a mug with some non-stick cooking spray
  2. Add all of your ingredients into it
  3. Mix everything together
  4. Microwave for around 1 1/2-2 minutes


  • Top it with some peanut butter!
  • Take it out of the microwave once it rises (keep an eye on it for next time)!

  • Hi, Derek…I can’t thank you enough for turning me on to Cold Brew Coffee. I use your basic recipe but I substitute Costco Kirkland Colombian pre-ground Coffee (I bought it because it’s about $3.00/pound and I am now addicted to it because I’ve never tasted anything better). Once I have the batch of cold brew coffee, I use it to make cold brew cappuccinos. I put 2/3s of a cup of cold brew coffee in a large mug. I add three Truvia’s per mug. Stir, then I microwave each mug of coffee for 2 minutes. During the microwave process, I make milk foam using the Nespresso foamer. I add the foamed milk to the microwaved Kirkland Coffee and it beats anything Starbucks ever served. I dust the top with some Costco cinnamon. There are less expensive foamers for the milk but Nespresso is the highest quality and we use this thing every day. Seriously, buddy, you have try this to believe it!!!
