## Why Zucchini in Coffee Cake?

Before we dive into the recipe, let’s address the elephant in the room: Why zucchini? Zucchini is a nutritional powerhouse, packed with vitamins and minerals. But more importantly for baking, it’s incredibly versatile. When grated, zucchini adds moisture without a strong flavor of its own. It essentially melts into the batter, creating a tender and soft crumb. You won’t even taste the zucchini, but you’ll definitely notice the difference it makes in the overall texture of the cake.

## Ingredients You’ll Need

Here’s a breakdown of the ingredients you’ll need for this Zucchini Coffee Cake. I’ve included some notes and substitutions where applicable:

**For the Cake:**

* **All-Purpose Flour:** The foundation of our cake. You can also use a 1:1 gluten-free flour blend.
* **Baking Powder & Baking Soda:** Leavening agents that help the cake rise. Make sure they’re fresh!
* **Salt:** Enhances the flavors of the other ingredients.
* **Ground Cinnamon:** Adds warmth and spice to the cake.
* **Ground Nutmeg:** A subtle hint of nutty flavor.
* **Eggs:** Bind the ingredients together and add richness. Use large eggs at room temperature.
* **Granulated Sugar:** Sweetens the cake.
* **Brown Sugar:** Adds moisture and a molasses-like flavor. You can use light or dark brown sugar.
* **Vegetable Oil:** Keeps the cake moist. You can also use canola oil or melted coconut oil.
* **Vanilla Extract:** Enhances the other flavors.
* **Grated Zucchini:** The star of the show! Make sure to squeeze out any excess moisture after grating.
* **Sour Cream or Greek Yogurt:** Adds moisture and tanginess. You can also use plain yogurt.

**For the Streusel Topping:**

* **All-Purpose Flour:** Provides structure for the streusel.
* **Brown Sugar:** Adds sweetness and a caramel-like flavor to the streusel.
* **Granulated Sugar:** Adds sweetness and crispness to the streusel.
* **Ground Cinnamon:** Enhances the flavor of the streusel.
* **Cold Butter:** The key to a crumbly streusel. Use unsalted butter, cut into small cubes.
* **Chopped Walnuts or Pecans (Optional):** Adds crunch and nutty flavor to the streusel.

## Step-by-Step Instructions

Follow these detailed instructions to bake the perfect Zucchini Coffee Cake:

**1. Prepare the Zucchini:**

* Wash and trim the ends of your zucchini.
* Grate the zucchini using a box grater. You’ll need about 2 cups of grated zucchini.
* Place the grated zucchini in a clean kitchen towel or cheesecloth and squeeze out any excess moisture. This step is crucial to prevent the cake from becoming soggy.

**2. Make the Streusel Topping:**

* In a medium bowl, combine the flour, brown sugar, granulated sugar, and cinnamon.
* Add the cold, cubed butter to the bowl.
* Using a pastry blender or your fingertips, cut the butter into the dry ingredients until the mixture resembles coarse crumbs. It’s important to keep the butter cold to prevent it from melting and creating a greasy streusel.
* Stir in the chopped walnuts or pecans, if using.
* Set the streusel topping aside.

**3. Prepare the Cake Batter:**

* Preheat your oven to 350°F (175°C).
* Grease and flour a 9×13 inch baking pan. You can also use a baking spray with flour.
* In a large bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
* In a separate bowl, whisk together the eggs, granulated sugar, brown sugar, oil, and vanilla extract until well combined.
* Add the wet ingredients to the dry ingredients and mix until just combined. Be careful not to overmix, as this can result in a tough cake.
* Gently fold in the grated zucchini and sour cream or Greek yogurt.

**4. Assemble and Bake the Coffee Cake:**

* Pour the cake batter into the prepared baking pan and spread it evenly.
* Sprinkle the streusel topping evenly over the cake batter.
* Bake for 30-35 minutes, or until a wooden skewer inserted into the center of the cake comes out clean.

**5. Cool and Serve:**

* Let the coffee cake cool in the pan for at least 15 minutes before slicing and serving.
* Serve warm or at room temperature. This cake is delicious on its own, but you can also serve it with a dollop of whipped cream or a scoop of vanilla ice cream.

## Tips for the Perfect Zucchini Coffee Cake

* **Don’t skip squeezing the zucchini!** This is the most important tip for preventing a soggy cake. Zucchini is naturally high in moisture, so it’s essential to remove any excess liquid before adding it to the batter.
* **Use cold butter for the streusel.** Cold butter will create a crumbly streusel topping. If the butter is too soft, the streusel will be greasy.
* **Don’t overmix the batter.** Overmixing will develop the gluten in the flour, resulting in a tough cake. Mix the wet and dry ingredients until just combined.
* **Use a light-colored baking pan.** Dark-colored baking pans can cause the edges of the cake to brown too quickly.
* **Check for doneness with a wooden skewer.** Insert a wooden skewer into the center of the cake. If it comes out clean, the cake is done. If it comes out with wet batter, continue baking for a few more minutes.
* **Let the cake cool before slicing.** This will allow the cake to set and prevent it from crumbling.

## Variations and Substitutions

* **Add chocolate chips:** Fold chocolate chips into the cake batter for a chocolatey twist.
* **Use different nuts:** Substitute the walnuts or pecans in the streusel topping with other nuts, such as almonds or macadamia nuts.
* **Add spices:** Experiment with different spices, such as cardamom or ginger, in the cake batter or streusel topping.
* **Use a different extract:** Substitute the vanilla extract with almond extract or lemon extract for a different flavor profile.
* **Make it gluten-free:** Use a 1:1 gluten-free flour blend in both the cake batter and streusel topping.
* **Make it vegan:** Substitute the eggs with flax eggs (1 tablespoon flaxseed meal mixed with 3 tablespoons water per egg), the sour cream or Greek yogurt with plant-based yogurt, and the butter with vegan butter.

## Storage Instructions

* **Room Temperature:** Store the Zucchini Coffee Cake in an airtight container at room temperature for up to 3 days.
* **Refrigerator:** For longer storage, store the cake in an airtight container in the refrigerator for up to 5 days. Let it come to room temperature before serving.
* **Freezer:** You can also freeze the coffee cake for up to 2 months. Wrap it tightly in plastic wrap and then in aluminum foil. Thaw in the refrigerator overnight before serving.

## Serving Suggestions

This Zucchini Coffee Cake is delicious on its own, but here are some serving suggestions to elevate your experience:

* **With coffee or tea:** The classic pairing! This cake is the perfect accompaniment to your morning coffee or afternoon tea.
* **With whipped cream or ice cream:** Add a dollop of whipped cream or a scoop of vanilla ice cream for a decadent treat.
* **With a glaze:** Drizzle a simple powdered sugar glaze over the cake for added sweetness and visual appeal. To make a glaze, whisk together 1 cup of powdered sugar with 2-3 tablespoons of milk or lemon juice until smooth.
* **As part of a brunch spread:** This cake is a great addition to any brunch spread.
