Chef's Pro-Tips

  • Mise en Place: Measure and prep all ingredients before you turn on the stove. This recipe moves quickly, and having everything ready prevents burning.
  • Fresh is Best: Whenever possible, use freshly squeezed lemon juice, whole garlic cloves, and fresh herbs instead of dried/jarred versions. The flavor difference is huge!
  • Don't Crowd the Pan: Leave room between ingredients. If the pan is overloaded, the moisture will steam the food instead of browning it.

Step-by-Step Instructions

Preheat oven to 350°F (175°C). Grease a 9x13 inch baking pan. Mix sugar, oil, and vanilla. Add flour, cocoa, baking soda, and salt.

Fold Zucchini

Fold in shredded zucchini and chocolate chips. Batter will look dry initially, but moisture from zucchini will hydrate it within 5 minutes.

Bake

Spread into prepared pan and bake for 28-32 minutes until edges pull away and top looks set.
