¾ cups (95 g) all-purpose flour, 1 tsp baking powder, ½ tsp salt, ½ tsp cinnamon
Gradually stir flour mixture into egg mixture with spatula.
Fold in grated zucchini.
1 cup (185 g before blotting) grated zucchini
Spread batter evenly into prepared jellyroll pan and bake on 350 for 13-15 minutes (edges may just begin to turn slightly golden).
While the cake is cooking, lay out a clean baking towel at least as wide as your jellyroll pan and dust generously with powdered sugar (this will help keep the cake from sticking to the towel while you are rolling it up).
Powdered sugar
As soon as cake is done cooking, remove from oven and invert immediately onto prepared dishtowel.
Remove jellyroll pan and very carefully peel foil away from cake.
Immediately, carefully, roll cake, starting with one of the 10" sides, using the towel to help you roll the cake but taking care to keep the towel from being rolled into the roll.
