Peanut Butter Zucchini Cake Ingredients For the Cake Batter Creamy Peanut Butter – Provides rich flavor and moisture; substitute with almond butter if desired. Brown Sugar – Adds sweetness and a hint of caramel flavor; white sugar can be used, but will slightly alter the taste. Egg – Binds the ingredients and contributes to the texture; a flax egg works as a vegan option. Vanilla Extract – Enhances flavor; can be substituted with almond extract for a different aroma. Buttermilk – Adds moisture and tang; create homemade buttermilk by mixing milk with lemon juice or vinegar. All-Purpose Flour – Provides structure and stability; use whole wheat flour for a healthier alternative. Kosher Salt – Balances sweetness; regular table salt works fine as a substitute. Baking Soda – A leavening agent for rising; ensure it’s fresh for the best results. Zucchini – Adds moisture without flavor; use small to medium zucchini for the best result. Peel and shred without draining. For the Topping Melted Peanut Butter – A rich drizzle that enhances peanut flavor and adds a beautiful finish. Chopped Peanuts – Optional for a crunchy texture; omit if nut-free. This Peanut Butter Zucchini Cake is a celebration of flavors that pleases the palate while sneaking in some veggie goodness! Enjoy baking this delightful treat! Step‑by‑Step Instructions for Peanut Butter Zucchini Cake Step 1: Preheat the Oven Begin by preheating your oven to 350°F (175°C). While it’s warming up, grease a 9-inch round cake pan with a bit of butter or cooking spray to ensure your Peanut Butter Zucchini Cake comes out easily after baking. This step is crucial for a perfectly shaped cake that retains its deliciousness when unmolded. Step 2: Mix the Wet Ingredients In a large mixing bowl, combine creamy peanut butter, brown sugar, egg, vanilla extract, and buttermilk. Use a hand mixer or a whisk to blend the ingredients until they achieve a smooth and creamy consistency, which should take about 2-3 minutes. The combination of these wet ingredients forms the flavorful backbone of your cake. Step 3: Combine the Dry Ingredients Next, gently whisk in the all-purpose flour, kosher salt, and baking soda to the bowl. Mix until just combined, being careful not to overwork the batter, as it may result in a denser texture. The batter may look dry at this stage, but don’t worry—this will change once you add the zucchini. Step 4: Fold in the Zucchini Now it’s time to add the secret ingredient! Gently fold in the shredded zucchini to the batter without draining it. Ensure the zucchini is mixed evenly throughout, as it contributes vital moisture and prevents your Peanut Butter Zucchini Cake from drying out during baking. Step 5: Pour and Bake Carefully pour the batter into your prepared cake pan, spreading it out evenly with a spatula. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out clean with a few moist crumbs attached. Keep an eye on it towards the end to avoid overbaking. Step 6: Cool and Drizzle Once baked, remove the cake from the oven and allow it to cool in the pan for about 10 minutes. Then, turn it out onto a wire rack to cool completely. After the cake has cooled, drizzle melted peanut butter over the top and sprinkle with chopped peanuts if desired. This finishing touch elevates your Peanut Butter Zucchini Cake to a delightful dessert.

Experiment with Flavors: Feel free to add spices like cinnamon or nutmeg for a delightful twist, enhancing the cake’s overall flavor profile. How to Store and Freeze Peanut Butter Zucchini Cake Room Temperature: Store the cake covered at room temperature for up to 3 days to maintain its delightful moistness and flavor. Fridge: If you want to keep it longer, place the covered cake in the refrigerator for up to 1 week. Just remember to bring it back to room temperature before serving for the best taste. Freezer: For longer storage, wrap individual slices or the whole cake tightly in plastic wrap and aluminum foil to prevent freezer burn. It can be frozen for up to 3 months. Reheating: To enjoy a slice later, thaw it in the fridge overnight and then allow it to come to room temperature or warm it slightly in the microwave for that freshly baked taste again.

Peanut Butter Zucchini Cake Recipe FAQs How do I choose the right zucchini for my cake? Absolutely! Opt for smaller to medium zucchinis, as they tend to be sweeter and contain fewer seeds. Look for zucchinis that are firm with a vibrant green color, avoiding any with dark spots or soft patches, which indicate overripeness. What is the best way to store leftover Peanut Butter Zucchini Cake? Very! Store the cake covered at room temperature for up to 3 days to keep it moist and delicious. If you’re planning to enjoy it over a longer period, or if you live in a particularly warm climate, refrigerate it in an airtight container for up to 1 week. Can I freeze my Peanut Butter Zucchini Cake? Absolutely! For freezing, wrap the cooled cake or individual slices tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It can stay fresh in the freezer for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the refrigerator, then bring it to room temperature or warm it slightly in the microwave. What should I do if my cake comes out too dry? If your cake turns out a bit dry, it could be due to overmixing the batter or overbaking. To avoid this, make sure to fold in the zucchini gently and check for doneness a few minutes early. If baking from frozen, ensure to bake it longer. Consider adding a simple syrup or an extra drizzle of melted peanut butter for added moisture and flavor. Is this cake suitable for people with nut allergies? Be careful! If you want to make this cake nut-free, simply replace the peanut butter with a sun butter or soy nut butter alternative, ensuring you also leave out the chopped peanuts as a topping. However, always check for any cross-contamination if nut allergies are a concern. Can I modify the ingredients for a healthier version? Absolutely! You can substitute whole wheat flour for all-purpose flour for more fiber, or use applesauce in place of some of the brown sugar to reduce calories. Additionally, a flax egg can be used in place of the regular egg to make it vegan-friendly!
