Preheat oven to 375°F.
In a large mixing bowl or stand mixer, combine eggs, sugar, oil, and extacts. Mix until well incorporated.
Add flour, baking powder, and any mix-ins (nuts, fruit, chocolate chips, etc.). When all ingredients are incorporated, divide dough into two equal logs. Place side by side on parchment paper on a baking sheet and flatten logs to about 1 inch thickness.
Bake for 25 minutes. Cool for 15 minutes.
When cool, cut at a diagonal into ½ inch slices. Place slices on parchment paper and bake on each side for 8 minutes.
Once out of the oven, let them cool and enjoy. Store them in an airtight container for up to a week.
