It is that time of year again when you hear a knock on the door. You answer it only to find that one of your well-meaning neighbors has abandoned yet another freakishly large zucchini on your doorstep. But your can-do attitude and culinary creativity will not be daunted! This recipe for zucchini muffins will help you put that Cucurbita pepo to good use. I love to slather these muffins with butter and enjoy them just like that, but alternatively, you can use my keto cream cheese frosting recipe, and presto chango – you have a cupcake! Who doesn’t enjoy a recipe that converts a vegetable into a cupcake?

Making The Muffins

I developed this recipe using my blend of keto-friendly flour alternatives that produce the BEST texture for low-carb baking! I will include that recipe below. It involves combining lupin flour, almond flour, coconut flour, vital wheat gluten, oat fiber, and xanthan gum. To read more about this flour blend and get another awesome fall-inspired recipe check out my Keto Pumpkin Muffins!

If you are not ready to try out this amazing, game-changing flour blend just yet for whatever reason, this recipe can be made using just almond flour and coconut flour with some xanthan gum. I have used this more common blend of flour alternatives with great success! These Keto Cinnamon Sugar Muffins use a blend of these two flours, and they will knock your socks off! For the exact ratio of Almond to coconut flour to use for these zucchini muffins please see the recipe notes in the recipe card below.

Pro Tip! Make sure to allow your zucchini time to sweat (15 minutes will probably suffice) after you grate it. Then blot the grated zucchini with a paper towel or a lint free dish towel. This important step will help you avoid soggy muffins. Nobody likes soggy muffins! Or, perhaps I am being presumptuous and informing that statement to much with my own opinion. If you prefer soggy muffins skip this step 😁

I used monk fruit sweetener in this recipe. I have started to use Lakanto Monk Fruit Sweetener almost exclusively. It has no bitter aftertaste and none of the strange cooling sensation of other keto-friendly sweeteners that I have tried. For this recipe, if you are making frosting, you will need granulated, brown, and powdered monk fruit. These are GREAT to have in your pantry! I use them for baked goods, to make jams, salad dressings, marinades, you name it.

These zucchini muffins are perfect just as they are slathered with a pad of butter! But if you want to dress them up with a gorgeous flourish of cream cheese frosting, then they will transform right before your eyes into the cutest dang cupcake you ever did see! I have affectionately termed them “mupcakes”, and I am hoping this word takes hold!

  • Stand Mixer optional


Zucchini Muffins

  • cups lupin flour blend (*see recipe notes for alternative) sifted
  • 1 tsp baking powder sifted
  • ½ tsp baking soda
  • ½ tsp salt sifted
  • 2 tsp cinnamon sifted
  • 1/4 tsp nutmeg sifted
  • ¾ cup granulated monk fruit sweetener
  • ¼ cup brown monk fruit sweetener
  • ½ cup butter melted
  • 2 tsp vanilla
  • 2 tbsp heavy cream
  • 2 whole eggs
  • cups shredded zucchini sweated and blotted

Keto Cream Cheese Frosting

  • ¾ cup powdered monk fruit sweetener
  • 2 tsp butter room temperature
  • 2-3 oz cream cheese room temperature
  • 3-4 tsp heavy cream start with 2 tsp, add more as needed
  • ½ tsp vanilla


Zucchini Muffins

  • Grate the zucchini and place it in a bowl lined with paper towels or a lint-free kitchen towel. Allow to sit for 15 minutes to release moisture, then blot with a towel before using.
  • Preheat the oven to425° and make sure to remove the cream cheese from the refrigerator if making frosting to allow it to soften. Line a muffin tin with paper liners.
  • Sift the lupin flour blend, baking powder, baking soda, salt, cinnamon, and nutmeg together in a mixing bowl.
  • In a separate mixing bowl combine the melted butter and white and brown monk fruit sweeteners with the vanilla and heavy cream. To this mixture, add the eggs one at a time making sure that each egg is fully incorporated.
  • Combine the wet and dry ingredients stirring until they are just incorporated, careful to not overmix.
  • Fold the prepared zucchini into the muffin batter.
  • Divide the batter evenly into the twelve lined muffin cups. Bake at 425° for 5 minutes, then reduce the temperature to 350° and bake for 20-25 minutes. Cook time can vary slightly depending on the amount of moisture retained in the zucchini.
  • Cool on a wire rack. Allow them to cool completely before frosting.

Keto Cream Cheese Frosting

  • Beat the butter and cream cheese using a stand mixer or hand-held electric mixer until smooth.
  • Add the powdered monk fruit and vanilla and mix until it begins to come together.
  • Start by adding 2 teaspoons of heavy cream and mixing. Add more cream until desired consistency is reached. I use between 3 and 4 teaspoons for perfect frosting.
  • Add the prepared frosting to a pastry bag with a frosting tip and frost those pretty babies! Alternatively, smear the frosting on haphazardly with a butter knife. It will taste just as good!
  • Enjoy!
