Easy Instructions for Peanut Butter Zucchini Cake

Step 1: Prepare the Oven

Fire up your oven to 350F (175C). Grab a 9×13-inch baking dish and coat it with grease and flour to prevent sticking.

Step 2: Blend Dry Ingredients

In a medium mixing bowl, whisk together:

Step 4: Incorporate Zucchini

Fold in freshly grated zucchini, ensuring it’s evenly distributed throughout the mixture.

Step 5: Merge Wet and Dry Mixtures

Gradually add dry ingredients to wet ingredients, stirring gently until just combined. Avoid overmixing to keep the cake tender.

Step 6: Bake to Perfection

Pour batter into prepared baking dish, spreading it evenly. Slide into the preheated oven and bake for 30-35 minutes. Check doneness by inserting a toothpick – it should come out clean. Allow cake to cool completely in the pan.

Step 7: Whip Up Creamy Frosting

In a separate bowl, cream together:
