Pizzelles by the Egg

This version of the recipe is for cookie math as well as variants like chocolate pizzelles, eggnog pizzelles, etc. I sometimes go up to 8 eggs or experiment with a couple, so I broke down the pizzelle recipe to a single egg.
Peter is responsible for the eggnog variant.
Ingredients
One Egg
- 1 egg
- ¼ c. sugar
- ⅙ c. pure olive oil (2 T + 2 tsp.)
- 1 tsp. extract (or ¼ tsp. flavor oil)
- scant ⅔ c. flour
- ⅔ tsp. baking powder
Two Eggs
- 2 eggs
- ½ c. sugar
- ⅓ c. pure olive oil
- 2 tsp. extract (or ½ tsp. flavor oil)
- 1 ⅙ c. flour (1 c. + 2 T + 2 tsp.)
- 1 ¼ tsp. baking powder
Three Eggs
- 3 eggs
- ¾ c. sugar
- ½ c. pure olive oil
- 1 T. extract (or 1 tsp. flavor oil)
- 1 ¾ c. flour
- 2 tsp. baking powder
Nine Eggs
- 9 eggs
- 2 ¼ c. sugar
- 1 ½ c. pure olive oil
- 3 T extract (or 1 T flavor oil)
- 5 ¼ c. flour
- 2 T baking powder
Directions
See the full pizzelle recipe for directions.

Variants
For real pizzelles use anise extract or oil.
For chocolate pizzelles use vanilla extract and add 1 T. cocoa and 1 T. sugar per egg.
For almond pizzelles use 1 tsp. almond extract.
For eggnog pizzelles use half the vanilla extract and add ¼ tsp. nutmeg and ⅓ tsp. ground clove. 
For cinnamon pizzelles use 1 tsp. vanilla extract and 1 tsp. cinnamon.
For other flavors use extract or oil.
For gluten-free pizzelles, use buckwheat flour.
To color pizzelles, use a few drops of food coloring. The baked color will be lighter than the dough color.
For two-toned pizzelles, use half a scoop each of two different colors (or chocolate and uncolored). Put them side by side on the iron. (The two-toned pizzelle idea came from a different chocolate pizzelle recipe at King Arthur Flour, which was too liquidy for my iron.)
