    Zucchini in Chocolate Cake??

    Now you might be thinking, "Wait a second… did you say there's zucchini in this chocolate cake?" Yep, that's right! This Amish chocolate cake has zucchini baked right in.

    While some people might pick up on it, most won't even notice. It blends in beautifully and adds amazing moisture and texture. It's a simple ingredient that makes the cake extra soft and rich, without overpowering the chocolate flavor.

    Ingredients: zucchini, applesauce, butter, sugar, flour, cocoa powder, baking soda, baking powder, espresso powder, eggs, vanilla, and chocolate chips

    Ingredients

    • All-purpose flour: The base of the cake that gives it structure.
    • Unsweetened cocoa powder: Adds deep chocolate flavor without extra sweetness. (I like to use dark cocoa powder for a richer taste.)
    • Baking soda & baking powder: Work together to help the cake rise properly and stay soft.
    • Salt: Balances the sweetness and enhances the chocolate flavor. (I prefer sea salt.)
    • Espresso powder (optional): This is one of my favorite tricks for chocolate baking. It deepens the chocolate flavor without making the cake taste like coffee. (affiliate link to espresso powder)
    • Chocolate chips: These melt into little pockets of chocolate throughout the cake, making it extra rich. (I like to use dark chocolate chips, but semi-sweet, milk chocolate, or mini chips all work great. Use whatever you normally enjoy in chocolate chip cookies.)
    • Butter: Adds richness and flavor. (I always use salted butter in my baking.)
    • Oil: Keeps the cake extra moist. (You can also substitute unsweetened applesauce for the oil if you prefer.)
    • Sugar: Sweetens the cake and helps with moisture and texture.
    • Eggs: Help bind everything together and give the cake structure. (Room temperature eggs work best.)
    • Sour cream (or Greek yogurt): Adds moisture and a soft, tender crumb with a slight tang that enhances the chocolate flavor.
    • Vanilla extract: Rounds out the flavor and adds warmth.
    • Zucchini: The secret ingredient that makes this cake incredibly moist. It blends right into the batter - you probably won't taste it, but you'll notice how soft it makes the cake.

    How to Prepare the Zucchini

    Wash the zucchini and shred it using a box grater. There is no need to peel it.

    If your zucchini is large, let it sit for a few minutes after shredding so excess moisture can drain off. A little moisture is fine and helps keep the cake soft, but you don't want it too watery.

    Frozen shredded zucchini also works well. Just thaw and drain slightly before using. (To freeze zucchini for using in this cake later: Simply shred the zucchini and store it in freezer bags, portioned into convenient 2 ½ cup servings. Then, when you want to make this Amish zucchini cake, just grab a package from the freezer and allow it to thaw before incorporating it into the recipe.)

    Step-by-Step Instructions

    1. Preheat the Oven:
      • Preheat your oven to 350°F (175°C).
    2. Mix Wet Ingredients:
      • In a large mixing bowl, cream together softened butter, oil (or applesauce), and sugar.
    3. Add Eggs:
      • Add 2 large eggs and mix well.
    4. Add Sour Cream and Vanilla:
      • Add sour cream (or Greek yogurt) and vanilla extract and mix well.
    5. Prepare Dry Ingredients:
      • In a separate bowl, mix together the all-purpose flour, cocoa powder, baking soda, baking powder, salt, and espresso powder (optional).
    6. Combine Wet and Dry Ingredients:
      • Add the dry ingredients to the wet mixture and mix just until combined.
    7. Add Zucchini, Chocolate Chips, and Nuts:
      • Stir in the shredded zucchini, chocolate chips, and chopped walnuts or pecans (optional).
    8. Bake:
      • Spread the batter into a greased 9x13" pan.
      • Bake for 42-48 minutes, or until a toothpick comes out with only a few crumbs.
    9. Cool and Top:
      • Let the cake cool.
      • Sprinkle with powdered sugar or top with chocolate ganache or your favorite frosting.

    Zucchini Cake with Chocolate Ganache Topping

    Chocolate ganache is a simple mixture of chocolate and warm cream that turns into a smooth, glossy topping.

    It can be poured over the cake while warm for a shiny finish or allowed to thicken slightly for a richer frosting-style topping. Either way, it adds a deep chocolate flavor that pairs perfectly with this cake.

    If preferred, you can opt for eating this cake without frosting, dust it with powdered sugar, or top it with my whipped chocolate buttercream instead.

    How to Use up an Overabundance of Summer Zucchini

    If you've ever grown zucchini in your garden, you're probably familiar with how quickly they produce (unless those pesky squash bugs ruin your plants).

    There are jokes about the abundance of zucchini, like this one: "Having too many zucchinis is like a never-ending game of hide and seek. You keep searching for new ways to use them, but they always find a way to sneak back into your kitchen!" 🙂

    These jokes reflect the common experience of gardeners dealing with an overwhelming surplus of zucchinis and their creative attempts to handle the situation.

    The good news is that zucchini can be used in various savory dishes, as well as in delicious desserts. It plays an impressive role in baked goods by adding moisture, tenderness, and a subtle sweetness from the vegetable itself.

    When you incorporate zucchini into recipes such as cakes, quick bread, dessert bars, or muffins, it provides a moist texture and prevents the baked goods from becoming dry. It also adds a gentle touch of natural sweetness.

    Additionally, zucchini adds nutritional value, as it is a good source of fiber and various vitamins. Its mild flavor allows it to seamlessly blend into baked goods, making it a versatile and beneficial ingredient for creating tasty and healthier treats.

    These Zucchini Bars with Cream Cheese Frosting are a crowd favorite!

      Try putting blackberries in this cake instead of the nuts. A friend here used blackberries in a chocolate cake mix and it was great

      This was absolutely amazing! I didn't make the ganache...but I'm sure that would've added another layer of decadence to this already indulgent cake! It was so rich and moist. In love with this recipe! Thanks for sharing:)
