Vanilla, with its aromatic and complex profile, has been a prized botanical for centuries. Its history dates back to the 12th-century Totonac people in present-day Mexico. The spice remained a labor-intensive luxury for hundreds of years until the 1840s, when chemist Joseph Burnett invented vanilla extract. While still derived from vanilla beans, the extract captured…
For many people, the scent of vanilla extract conjures up fond memories of baking. Because it’s a key component in so many desserts — including cakes, cookies, and creamy custards — it sparks that instant sensory connection.
Most bakers measure their vanilla with a measuring spoon, of course. But there’s a much simpler way to get a precise pour without ever opening the utensil drawer.
The One-Cap Plus Splash Shortcut
The secret lies in the packaging: It turns out that the caps on many major brands of vanilla extract measure either 1/2 or 3/4 teaspoon. McCormick, the most popular brand of vanilla extract in the U.S., offers two common sizes: a 2-ounce bottle with a 1/2 teaspoon cap and a 4-ounce bottle with a 3/4 teaspoon cap.
Because most cake and cookie recipes call for a full teaspoon, savvy bakers follow the “cap and splash” rule: one capful of vanilla extract followed by a generous splash to make up the difference. While you should verify this with your specific bottle first, you can likely skip the measuring spoon the next time you bake a batch of chocolate chip cookies.

Tips and Cautions
Verify this method once before proceeding by filling a capful and pouring the liquid into a measuring spoon. Remember: The volume can vary by brand and bottle size. Also note that this trick may not work for other extract flavors, or for imitation vanilla, which is an entirely different product.
Using an exact measurement of vanilla rarely makes or breaks a recipe. It doesn’t trigger a precise chemical reaction like baking powder does. If your recipe calls for 1 teaspoon of vanilla extract and your cap measures 3/4 of a teaspoon, it will usually suffice. The only risk is overwhelming a recipe with too much vanilla — its potent flavor can easily dominate other ingredients. If you’re scaling up a recipe to feed a crowd, it’s worth the extra step to measure out the vanilla.
