The Chemistry of Zucchini Muffins

The key to moist and tender muffins is the balance of wet ingredients and dry ingredients. The zucchini provides a lot of moisture, which is balanced by the dry ingredients like all-purpose flour, baking soda, and baking powder. Vegetable oil is used in place of butter to keep the muffins light and fluffy. Additionally, the eggs act as a binder, while the brown sugar adds depth of flavor and moisture to the batter. Make sure to squeeze out any excess moisture from the shredded zucchini with a paper towel before adding it to the batter to avoid making the muffins too wet.

What is in zucchini muffins?

All-purpose Flour

Builds structure as it absorbs liquids and expands. All-purpose flour falls in the middle of bread flour (high in gluten) and cake flour (low in gluten). It’s exactly what it is named, all-purpose, the most universal flour that can be used in most baked goods.

Cinnamon

A seasoning that adds a nice spice to your treat.

Fine Sea Salt

Enhances flavor, adds balance, masks any bitter flavors. Salt is the most powerful and oldest preservative. Always make sure to use fine sea salt so it melts down at the right speed in the heat of the oven. If you use larger granule salt, it will not melt down fully when baked and will leave salt crystals throughout your treat, making it crunch like you dropped it into sand.

Baking Soda

Elevates the pH level of your batter or dough. It increases the spread in your treat and encourages browning, which gives the crispy outside and soft inside texture that everyone loves. Baking soda needs both an acid and a liquid to react. Things that will activate your baking soda are: vinegar, fruit juice, molasses, brown sugar, tartar, buttermilk and sour cream. Baking soda only reacts once, which is right when it’s mixed into your batter or dough. The soda creates little air bubbles all throughout your treat. When the air bubbles get heated up in the oven, they expand.

Baking Powder

Puffs up your batter or dough instead of spreading it out. Baking powder contains a little bit of baking soda, an acid & cornstarch. Because of this, it only needs a liquid to react. It also consists of two different acids, so it’s double reacting. It reacts as soon as it’s mixed with a moisture and then again when it’s heated up.

Eggs

Adds both a protein (egg whites) and fat (egg yolks). The egg whites help with rising because, when foamed, little air pockets get trapped inside the egg white mixture. The water content in egg whites encourages steam while baking, which helps with gluten formation, resulting in nice and thick treats. Egg yolks have emulsifying properties that bring batters and doughs together and help them from collapsing. Unless otherwise specified, always use large eggs.

Granulated Sugar

Adds sweetness, provides a caramelized flavor and crisp texture. Sugar assists with rising when creamed with butter. It helps add moisture to your treat and helps it evenly spread as it melts into a liquid in the heat of the oven. Sugar also helps with naturally preserving your baked treat.

Brown Sugar

Is granulated sugar with a little molasses mixed in. Molasses is a somewhat smoky flavored natural sweetener, which makes brown sugar a bit sweeter than granulated sugar. Brown sugar draws more moisture into your treat, keeping it softer for longer. It’s also more acidic, which means it will help activate your baking soda.

Vegetable Oil

100% fat, contains no water and has a higher melting point. This means it will not melt down in your oven, resulting in thicker cookies or brownies. It doesn’t help leaven your treat like butter can, so it can make your treat flatter and greasier.

Vanilla Extract

When using pure vanilla extract, as opposed to imitation flavoring, it will add the deep rich flavor that everybody wants in a treat.

Grated Zucchini

The star ingredient that adds moisture and a subtle sweetness.

Brown Sugar

Is granulated sugar with a little molasses mixed in. Molasses is a somewhat smoky flavored natural sweetener, which makes brown sugar a bit sweeter than granulated sugar. Brown sugar draws more moisture into your treat, keeping it softer for longer. It’s also more acidic, which means it will help activate your baking soda.

Melted Butter

It is important to use melted butter when it is called for. Melted butter evenly coats the gluten in the recipe and helps bind the ingredients. You can also use melted butter as a substitute for vegetable oil.

How do you make zucchini muffins?

Muffins

  1. Preheat your oven to 325 degrees. Line the muffin tin with 24 muffin liners or spray with cooking spray.
  2. Mix the dry ingredients. In a medium bowl, whisk together 3 cups of all-purpose flour, 2 tablespoons of cinnamon, 1 teaspoon of fine sea salt, 1 teaspoon of baking soda, and 1/4 teaspoon of baking powder. Set aside.
  3. Mix the wet ingredients. In a large bowl, whisk together 3 eggs, 1 cup of granulated sugar, 1 cup of brown sugar, 1 cup of vegetable oil, and 2 tablespoons of vanilla extract until smooth.
  4. Combine the wet and dry ingredients. Gradually pour the wet ingredients into the dry ingredients, stirring until combined. Fold in the 2 cups of grated zucchini using a rubber spatula.
  5. Spoon the batter. Divide the muffin batter evenly into the prepared muffin cups, filling each about 3/4 full.

Topping

  1. Make the topping. In a separate bowl, combine 1/2 cup of all-purpose flour, 1/2 cup of brown sugar, 4 tablespoons of melted butter, and 1/2 teaspoon of cinnamon. Stir until it forms a crumbly mixture.
  2. Sprinkle the topping evenly over the tops of the muffins.
  3. Bake the muffins in the preheated oven for 30-35 minutes, or until the tops of the muffins are golden brown and a toothpick inserted into the center comes out with a few moist crumbs.
  4. Cool the muffins. Remove the muffins from the oven and allow them to cool for 5 minutes in the muffin tin before transferring them to a wire rack to cool completely.
