Step-by-Step Baking Instructions

Let’s bake the most amazing muffins you’ve ever had!

Part 1: Mixing the Batter

Preheat and Prep: First, preheat your oven to 350°F (175°C). Grease a standard 12-cup muffin tin with nonstick spray or line it with paper liners.
Combine Wet Ingredients: In a large mixing bowl, whisk together the egg, brown sugar, and granulated sugar. Add the melted coconut oil, sour cream, vanilla extract, and ground cinnamon, and mix until everything is smooth and well combined.
Add the Veggies: Stir the shredded carrots and shredded zucchini directly into the wet ingredients until they are evenly distributed.
Mix the Dry Ingredients: In a separate, smaller bowl, whisk together the all-purpose flour, baking powder, baking soda, and the pinch of salt.
Combine Wet and Dry: Add the dry ingredients to the large bowl with the wet ingredients. Stir with a spatula until just combined. To ensure a tender muffin, be careful not to overmix!
Fold in Nuts: If you’re using them, gently fold in the chopped pecans or walnuts.

Part 2: Baking to Perfection

Fill the Muffin Tin: Spoon the batter evenly into your prepared muffin tin, filling each cup about two-thirds to three-quarters full.
Bake: Place the muffin tin in your preheated oven and bake for 20-22 minutes. The muffins are ready when a toothpick inserted into the center comes out clean. Note: The tops may be slightly sticky, which is perfectly normal!
Cool and Enjoy: Let the muffins cool in the pan for a few minutes before transferring them to a wire rack to cool completely.

Tips for Success and Tasty Variations

Veggie Prep: For this recipe, there’s no need to squeeze the moisture out of the shredded zucchini or carrots. That liquid is key to the super-moist texture!
Cream Cheese Frosting: To take these truly into carrot cake territory, whip up a simple cream cheese frosting! Beat together 4 oz of softened cream cheese, 2 tbsp of softened butter, 1 cup of powdered sugar, and ½ tsp of vanilla extract until smooth. Spread over the cooled muffins.
More Fun Add-Ins: Feel free to add ¼ cup of raisins, sweetened shredded coconut, or even pineapple tidbits (well-drained) to the batter along with the nuts.
Storage: Keep the muffins in an airtight container at room temperature for up to 3 days. If you add cream cheese frosting, be sure to store them in the refrigerator.

Frequently Asked Questions (FAQs)

Q1: Can I make these muffins vegan?
Yes, you can make these muffins vegan by using flax eggs instead of regular eggs. Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water for each egg, and let it sit for a few minutes until it thickens.

Q2: How can I make the muffins more moist?
To make the muffins even more moist, you can add an extra 1/4 cup of grated zucchini or carrot. Just be sure to squeeze out any excess moisture before adding it to the batter.

Q3: Can I use whole wheat flour instead of all-purpose flour?

When stored in an airtight container at room temperature, these muffins will stay fresh for up to 3 days. If you refrigerate them, they can last up to a week, but bring them to room temperature before serving for the best flavor.
