How can I substitute applesauce in baking, like in these muffins?

Applesauce offers a lot to a baking recipe, such as natural sweetness and moisture. When swapping out applesauce in baking, my first go-to is mashed banana. I find that I can swap them out one-for-one in a sweet baking recipe with consistent success. And I often do it when making these Chocolate Chip Zucchini Muffins!

How should I store these zucchini muffins?

Like with any baked good, be sure to let these muffins cool on your counter completely before storing.

After they are cool, transfer the muffins to an air-tight container. You can leave them at room temperature for up to 2 days. After that, I suggest storing them in the fridge or freezer to prevent molding and to keep them as fresh as possible for days to come. They also freeze beautifully and make for a great breakfast or snack to stock up on!

Suggested Adaptations

  • Make them with carrot instead of zucchini. No zucchini in the garden or fridge? Just swap it out for shredded carrot…or even summer squash!
  • Use summer squash instead of zucchini. Many people don’t know you can swap zucchini and yellow summer squash in most recipes!
  • Reduce the sugar and skip the chocolate chips. Everyone prefers a different level of sweetness. If you are looking to minimize the sugar in these zucchini muffins, simply omit the chocolate chips.
  • Replace the chocolate chips with raisins. It is all a matter of preference.
  • Replace the applesauce with 2 medium ripe mashed bananas. No applesauce on hand or just love bananas? Go ahead and make the switch!

Tips and tricks

  • Let them cool completely. If you want to dive right in and enjoy a Chocolate Chip Zucchini Oatmeal Muffin warm (because that is kinda the best thing ever), go for it. But don’t freak out if they stick to the papers a little or are slightly soft in the middle. Both are normal and as the muffins cool, both issues will resolve.
  • Blend the oats into oat flour first. If you are not using a high-speed blender like a Vitamix, consider blending the oats into a flour first. Why? Because this will help you to break down the oats easier and give your muffins a better texture.
  • Don’t skip on squeezing out the zucchini. Zucchini naturally has a lot of water. Squeezing out some of the zucchini’s natural moisture is essential so that these oatmeal muffins come out perfectly moist instead of mushy. Be sure to measure your loosely packed zucchini prior to squeezing out the moisture.
  • Bake them until they have an internal temperature of 200℉. Every oven bakes a little different and often cooks higher or lower than you might realize. You can use a kitchen thermometer to make sure your muffins are baked through without over baking.
  • Let your muffins cool for 15 minutes before enjoying. Baked goods firm up as they cool and will release muffin tin liners easier.

Wholesome Chocolate Chip Zucchini Oatmeal Muffins

Yield: 12 muffins
Prep Time: 5 minutes
Cook Time: 25 minutes
Cuisine: American
Course: Breakfast
These Chocolate Chip Zucchini Oatmeal Muffins are so easy to throw, bake up in 20 minutes, and are beyond delicious. Made from blended oats, naturally sweetened with applesauce + a little maple syrup, rocking a cup of grated zucchini, and studded with chocolate chips, these healthy muffins make for the perfect one-the-go breakfast and tasty snack.

Ingredients
 

  • 1 cup grated zucchini, loosely packed, (squeeze out moisture after measuring)
  • ¾ cup unsweetened applesauce, you can sub very ripe banana
  • ¼ cup milk of choice
  • cup maple syrup, or honey*
  • 2 large eggs
  • ¼ cup avocado oil, or melted coconut oil
  • ½ Tablespoon pure vanilla extract
  • 2 ½ cups rolled oats, if gluten free is important, make sure the oats are certified gluten free
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon nutmeg
  • 1 teaspoon baking baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • cup chocolate chips , +extra for topping

Equipment

Instructions
 

  • Preheat oven to 350℉ and line a 12-hole muffin tin with liners.
  • Take the measured, loosely packed grated zucchini and place it in the middle of a clean dish towel or large paper towel. Wrap the zucchini in the towel and squeeze out as much of the moisture as you can.
  • Place drained zucchini in a medium bowl. Add applesauce, milk, maple syrup, eggs, oil, and vanilla. Whisk to combine. Set aside
  • Pour oats, cinnamon, nutmeg, baking powder, baking soda, and salt into your blender. Pulse until very finely ground and the oats resemble a fine flour. I find running my blender for 10-15 seconds, stopping and shaking my blender a bit and running it again helps to ensure that the oats are evenly pulverized.
  •  Once oat mixture is finely ground, pour it into the bowl with the zucchini and wet ingredients. Stir with a spatula to combine into a batter.
  • Add chocolate chips to the batter and fold them in.
  • Portion the batter out between the 12 lined muffin tin holes. Sprinkle extra chocolate chips on top of the muffins if desired.
  • Bake for 20-22 minutes or until a toothpick inserted into the middle comesout clean.
    TIP: If you have a food thermometer, bake until the muffins have aninternal temperature of 200℉. This will ensure your muffins are baked throughbut not over baked
  • Let your muffins cool for 15 minutes before enjoying. Baked goods firm up as they cool and will release muffin tin liners easier.
    If saving for later, allow the muffins to cool completely before transferring to an air-tight container. Store in fridge for 4-5 days or in freezer for up to a month.
