Instructions:
Preheat and Prep Your Pan
First things first, let’s get our oven ready and prepare our baking pan. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). This ensures that the cake bakes evenly from the moment it goes in. Next, take an 8×8 inch square baking pan or a 9-inch round cake pan. Grease it thoroughly with butter or cooking spray. For an extra layer of protection against sticking and to make removal a breeze, I like to lightly flour the greased pan, tapping out any excess flour. This is a small step that can make a big difference when it’s time to unmold your beautiful cake.
Combine Dry Ingredients
In a medium-sized bowl, whisk together the dry ingredients. This includes the 1 and 1/2 cups of all-purpose flour, 1 teaspoon of baking soda, 1/2 teaspoon of salt, 1 teaspoon of ground cinnamon, and 1/2 teaspoon of ground nutmeg. Whisking these together ensures that the leavening agents (baking soda) and spices are evenly distributed throughout the flour. This prevents pockets of baking soda or concentrated spice flavor in your finished cake, leading to a more uniform and delicious result. Set this bowl aside for now.
Cream Wet Ingredients and Add Peanut Butter
In a large mixing bowl, cream together the granulated sugar and packed light brown sugar with the softened unsalted butter. You can use an electric mixer for this, starting on low speed and gradually increasing to medium-high speed. Beat until the mixture is light and fluffy, which usually takes about 3-5 minutes. This creaming process incorporates air into the butter and sugar, which contributes to the cake’s tender crum extractb. Now, add the 3/4 cup of smooth peanut butter to this mixture. Beat again until it’s well combined and smooth. Next, add the 2 large eggs, one at a time, beating well after each addition to ensure they are fully incorporated. Finally, stir in the 1 teaspoon of vanilla extract.
Incorporate Zucchini and Buttermilk Alternately
Now for the stars of our show! Add the grated zucchini that you’ve squeezed dry to the wet ingredients. Gently fold it in until it’s just combined. The squeezing of the zucchini is important; it removes excess water which can make the cake soggy. You can do this by placing the grated zucchini in a clean kitchen towel or cheesecloth and wringin extractg it out thoroughly. Now, it’s time to alternate adding the dry ingredients and the buttermilk to the wet mixture. Add about one-third of the dry ingredients and mix on low speed until just combined. Then, add half of the buttermilk and mix again. Repeat this process, adding another third of the dry ingredients, the remaining buttermilk, and finally the last of the dry ingredients. Be careful not to overmix at this stage. Overmixing can develop the gluten in the flour too much, resulting in a tougher cake. Mix only until you no longer see streaks of dry flour.
Bake and Cool
Pour the batter into your prepared baking pan and spread it evenly. Place the pan in the preheated oven. Bake for approximately 30-40 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The baking time can vary slightly depending on your oven, so it’s always best to check for doneness a little before the suggested time. Once baked, remove the cake from the oven and let it cool in the pan on a wire rack for about 10-15 minutes. This allows the cake to set up slightly before you attempt to remove it. After this initial cooling period, carefully invert the cake onto the wire rack to cool completely. Letting it cool on a wire rack allows air to circulate all around the cake, preventing it from becoming soggy on the bottom. Once completely cool, slice and enjoy this delightful Peanut Butter Zucchini Cake! You can dust it with a little powdered sugar or add your favorite frosting if you wish.

I love serving this cake warm with a dollop of whipped cream or a scoop of vanilla ice cream. It also pairs wonderfully with a glass of cold milk or a hot cup of coffee. For variations, consider adding a handful of chocolate chips to the batter for an extra burst of indulgence, or swirl in some raspberry jam for a delightful fruity contrast. Don’t be afraid to experiment with a sprinkle of chopped peanuts on top for added crunch! I truly encourage you to give this Moist Peanut Butter Zucchini Cake a try; I’m confident you’ll be as delighted with the outcome as I am every time I bake it.
Frequently Asked Questions:
Can I make this cake ahead of time?
Absolutely! This cake is even better the next day, as the flavors meld together beautifully. Store it in an airtight container at room temperature for up to 3 days, or in the refrigerator for a slightly longer shelf life. If refrigerating, allow it to come to room temperature before serving for optimal moisture and flavor.
My zucchini has a lot of seeds. Will that affect the cake?
While it’s best to use zucchini that isn’t overly seedy, a few seeds won’t ruin your cake. You can gently squeeze out some of the excess moisture from grated zucchini before adding it to the batter. If your zucchini is particularly watery, you might notice a slightly denser cake, but it will still be delicious and moist thanks to the peanut butter and other ingredients.
What kind of peanut butter should I use?
For the best flavor and texture, I recommend using standard creamy peanut butter (the kind you find in a squeeze bottle). Natural peanut butters that separate might alter the texture slightly, but they will still work. If you use a natural peanut butter, ensure it’s well-stirred and as smooth as possible before measuring.
