This chocolate chip zucchini cake recipe is a great way to use up summer zucchini. It's made with all-purpose flour, sugar, baking powder, salt, eggs, grated zucchini, milk, vegetable oil, vanilla extract, and chocolate chips. To make the cake, mix the dry ingredients together, then add the wet ingredients and mix until smooth. Fold in the chocolate chips and grated zucchini and pour the batter into a greased cake pan. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool before slicing and serving. This cake is moist, fluffy, and has a subtle zucchini flavor that pairs perfectly with the chocolate chips.
