Combine 3 c all purpose flour, 1 tsp baking powder, 1 tsp baking soda, 1 tsp salt, and 1 tbsp ground cinnamon. Set aside.
In a large bowl combine 3 eggs, 2 c sugar, 1 c vegetable oil, and 1 tsp vanilla extract. Beat at medium speed with an electric mixer until well blended. Stir in 2 c zucchini and 1 c pecans.
Add reserved dry ingredient mixture, stirring until just moistened.
Spoon into 3 greased and floured 1 lb bread pans (or optional mini loaf pans). Bake for 55-60 minutes or until a toothpick inserted into the center comes out clean. For mini loaves bake for 35-40 minutes.
Notes
Lisa makes a bunch of these at the end of the summer when zucchini is plentiful and freezes them.
