Instructions:
Prepare the Brown Butter Base
Mix the Dry and Wet Ingredients
- In a large mixing bowl, whisk together the 2 1/2 cups of all-purpose flour, 1 cup of packed light brown sugar, baking soda, salt, 1 1/2 teaspoons of ground cinnamon, and the ground nutmeg. Ensure these dry ingredients are thoroughly combined to distribute the leavening agents and spices evenly. In a separate medium bowl, whisk together the slightly cooled brown butter, Greek yogurt (or sour cream), eggs, and vanilla extract until well combined and smooth. This is where the moisture and richness will come from, ensuring a tender crumb.
- Pour the wet ingredients into the bowl with the dry ingredients. Using a spatula or a wooden spoon, mix until just combined. Be careful not to overmix; a few streaks of flour are perfectly fine at this stage. Overmixing can lead to a tougher cake. Now, gently fold in the 1 1/2 cups of shredded zucchini. Remember, we are intentionally leaving the liquid in the zucchini. This liquid will add incredible moisture to the cake and break down slightly during baking, contributing to its tender texture. The zucchini pieces should be distributed evenly throughout the batter.
- To create the irresistible crumble topping, place the remaining 4 tablespoons of unsalted butter into a medium bowl. You can either melt this butter in the microwave or in a small saucepan over low heat until just melted. Add the 1/2 cup of packed brown sugar and the 1/2 cup of all-purpose flour, along with the remaining 1/2 teaspoon of ground cinnamon. Use a fork or your fingertips to mix these ingredients together until they form coarse crumbs. You want a texture that resembles wet sand, with some larger clumps. This topping will bake into a delightful crunchy layer.
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan or an 8×8 inch square pan. Pour the zucchini batter into the prepared pan, spreading it evenly. Sprinkle the prepared crumble topping evenly over the surface of the batter. Place the pan in the preheated oven and bake for 35-45 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The topping should be golden brown and crisp. If the topping starts to brown too quickly before the cake is cooked through, you can loosely tent the pan with aluminum foil.
- Once baked, remove the coffee cake from the oven and let it cool in the pan on a wire rack for at least 15-20 minutes before slicing. This allows the cake to set properly. For the best flavor and texture, it’s ideal to let it cool completely before cutting. This Brown Butter Zucchini Coffee Cake is delicious served warm or at room temperature. It doesn’t require any frosting, but a light dusting of powdered sugar is always a welcome addition. Enjoy this wonderfully moist and flavorful cake!

Frequently Asked Questions:
Can I freeze this coffee cake?
Yes, absolutely! This Brown Butter Zucchini Coffee Cake freezes beautifully. Once completely cooled, wrap it tightly in plastic wrap, then in aluminum foil. It will keep well in the freezer for up to 2-3 months. Thaw it overnight at room temperature or gently reheat slices in a low oven.
My zucchini is very watery. How do I prevent a soggy cake?
This is a common concern with zucchini baked goods! The key is to shred your zucchini and then squeeze out as much excess moisture as possible before adding it to the batter. You can do this by placing the shredded zucchini in a fine-mesh sieve and pressing down with a spoon, or by wrapping it in a clean kitchen towel and wringing it out. This step is crucial for achieving that perfect, moist-yet-not-soggy texture.
