When I make or eat muffins, the talking muffin joke always comes to mind. I still don’t really get it, but it’s a classic at this point. Two muffins were sitting in an oven. One turned to the other and said: “Hey, it’s pretty hot in here, isn’t it?” The other turned and shouted, “Oh my gosh a talking muffin!” Anyway, these Chocolate Zucchini Muffins are no joke. No one will believe that they are made with zucchini, but that is actually the secret to the moistness! For those doubters who could never fathom putting zucchini in a dessert, this will change their minds!

Chocolate Zucchini Muffins Recipe

This Chocolate Zucchini Muffins Recipe is taken from my Zucchini Brownies recipe but in a muffin form. Since muffins are more accepted as a breakfast food than brownies, it would be completely justified to have one of these muffins for breakfast! They are simple to make, and again, the zucchini does most of the work here!

You will notice that there are no eggs or butter added to this recipe. They are absolutely not needed! These Chocolate Zucchini Muffins bake up beautifully and do not need the added air and flavor that eggs usually add. This is a great recipe for vegan friends!

The Secret to Baking with Zucchini

Size matters. A large zucchini will be drier. A small zucchini with have more moisture. Certain recipes work best with different sizes. For instance, I tend to use a medium to small with this recipe because I want the moisture the zucchini brings, but I use a large zucchini for my Double Chocolate Zucchini Cupcakes.

Use the fine side of your grater. Coarser pieces will have a slightly more noticeable flavor and texture in a finished cake or bread recipe. (Farm kids tend to want that!)

Some recipes ask that the zucchini is pressed well with a clean towel to soak up excess moisture or to prevent whatever your baking from getting too soggy. Pay close attention to the recipe that you are making with zucchini as the level of moisture they provide is important. For instance, in this Chocolate Zucchini Muffins recipe, the zucchini is the main source of moisture and should NOT be drained! 

Can I Use Frozen Zucchini?

Yes, you can! First, bring the frozen zucchini to room temperature. Since frozen zucchini collects extra moisture, you WILL have to drain it before adding it to the recipe. If your batter looks too thick, you may need to add a little extra oil in the mix, starting with a teaspoon at a time.

How to Store Muffins

There are a few ways to properly store muffins.

  • Room Temperature: Because they are best enjoyed at room temperature, this is usually the recommended way to storing. I use a larger sealable plastic bag or an airtight container to store the muffins in a single layer. Some folks recommend adding a piece of paper towel to the bottom so that it will soak up any condensation. If your muffins are properly cooled before storing, this may not be necessary. However, if I am using an airtight container, I will often add a piece of bread to the container, torn in half, and fit in between the muffins. The bread will soak up moisture as well. Best enjoyed within 2-3 days.
  • Refrigerator: (Refrigeration, in general, dries out baked goods faster so a typical muffin recipe shouldn’t be refrigerated.) Place in a sealable plastic bag or airtight container and then place into the refrigerator. They should keep for up to 5 days. To reheat, remove from refrigerator pop into the microwave for 10 seconds or just allow muffin to come to room temperature naturally, about 15 minutes.
  • Freezer: Place cooled muffins into a freezer-safe sealable plastic bag or a freezer-safe airtight container and pack as closely as possible without crushing. Remove as much air as possible. Label with date and recipe name.

  1. The kids absolutely DEVOURED these, and I had the whole gang of neighborhood kids knocking on the door for some! Absolutely a bookmarked recipe for this household!!!
    I was skeptical of the no egg thing, and even as I began to mix, thought, “how is this going to become a batter???”, but obviously the recipe works as it’s written – and within a few minutes of mixing, the right consistency arrived! These are perfect! I’ll be experimenting with time for mini muffins my next time around!!!
