Discover Your New Favorite: The Best Zucchini Carrot Cake Recipe
This particular **Zucchini Cake recipe** has become my ultimate go-to, perfect for using up garden zucchini. I always grate and freeze my zucchini in 2-cup portions, allowing me to enjoy this cake year-round. While carrots add a lovely sweetness and subtle texture, you can easily omit them; the cake remains exceptionally moist and flavorful. Zucchini is the unsung hero here, acting as a natural moistening agent, much like applesauce or bananas for muffins – hard to detect, but essential for that incredibly tender crumb.
My love for this cake started when Mary Beth brought her fantastic spice cake from a Mennonite cookbook to a Church Fellowship. The original, “Shredded Zucchini Bars,” was an instant hit. Inspired by my cravings for both carrot cake and zucchini, I created this unique concoction. The result is truly the most tender zucchini cake you can make from scratch! Who can resist a perfectly spiced cake generously topped with luscious cream cheese frosting? This versatile recipe works beautifully baked as a sheet cake, individual muffins, or even a hearty zucchini bread, promising a satisfying and wholesome treat.
Frequently Asked Questions (FAQ)
How To Properly Freeze Zucchini for Baking & Cakes?
To freeze zucchini for baking: wash, trim, and grate. **Do not drain the liquid**; it’s crucial for moist cakes! Portion shredded zucchini with juices into 2-cup freezer bags, remove air, label, and freeze. Thaw and use directly in recipes for consistently tender and flavorful cakes or muffins all year.
Should You Drain the Liquid from Zucchini for Baking?
For cakes, muffins, and sweet loaves, **do not drain zucchini liquid**. This moisture ensures a tender, moist crumb and prevents dryness, absorbing perfectly during baking. For savory items like Zucchini Fritters, draining is necessary for crispiness. For this Zucchini Cake, embrace the natural moisture for optimal, delicious results!
Can I Substitute Butter for Margarine in Cream Cheese Frosting?
Yes, softened unsalted butter can replace margarine. Butter offers a richer flavor and creamier texture. It firms up more when chilled than margarine, providing stability for piping but making it stiffer directly from the fridge. Ensure your fat is truly room temperature before mixing for a smooth, lump-free frosting.
Why Is My Frosting Runny? Troubleshooting Tips
Runny frosting is often caused by overly warm/melted fat (butter/margarine) or insufficient powdered sugar. Fat needs to be softened, not liquid; chill if too warm. Powdered sugar provides structure; gradually add more, beating well, until desired thickness. Also, ensure cream cheese is at room temperature for smooth blending.
How to Quickly Soften Butter or Margarine in the Microwave:
To soften quickly: place stick (in paper wrapper) on a microwave-safe plate. Microwave in 5-10 second bursts, flipping/rotating after each. Gently press to check softness. Stop when pliable but still solid. Butter takes ~20-30 seconds; margarine faster. Be vigilant to avoid melting! Once soft, it’s ready for your recipe.
Can I Omit Carrots from This Zucchini Cake Recipe?
Yes, absolutely! Carrots add subtle sweetness, but omitting them won’t sacrifice moisture or deliciousness. The original inspiring recipe was carrot-free. My version integrated carrots for a carrot cake twist. Without them, your cake remains incredibly moist, rich, and full of spice flavor. No significant adjustments are needed, making the recipe flexible for your preference.
Can I Use Whole Wheat Flour in My Zucchini Cake?
Yes, whole wheat flour can be used. The cake pictured uses a 50/50 blend for balanced texture. Using 100% whole wheat may result in a slightly denser or grittier crumb due to bran and germ. While zucchini helps moisture, the texture will differ. For a tender cake with whole grains, consider starting with a blend. Avoid overmixing.
Can I Substitute Melted Coconut Oil in This Zucchini Cake?
Yes, melted coconut oil is an excellent substitute for canola oil, adding richness and moisture. Choose refined (unscented) for classic spice flavor, or unrefined (virgin) if you like a subtle coconut taste complementing the spices. Ensure it’s fully melted and measured accurately as a liquid before adding to your batter for smooth mixing and perfect results.
