Ingredients

Directions

Prepare the dough

  1. Place rolled oats, bran, and pecans in a bowl and mix lightly, then set aside.

  2. Cream margarine and sugars together at medium speed until light and fluffy.

  3. Add egg whites, vanilla, and water, and mix at medium speed for 1 minute, scraping down the bowl before and after adding egg whites, vanilla and water.

  4. Stir flour, baking powder, baking soda and salt together, add to the creamy mixture, and mix at medium speed only until oatmeal is blended into dough.

Bake and cool

  1. Drop by 1½ tablespoonfuls onto a cookie sheet that has been sprayed with Pam spray or lined with aluminum foil.

  2. Bake at 375°F for about 12 minutes; then remove cookies to a wire rack and cool to room temperature.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Margarine
Creamed with sugar to trap air, giving the cookies a light, tender texture and fat for richness.
All-purpose flour
Provides the starch and gluten network that gives the cookies their structure.
Egg whites
Add moisture and protein that help bind the dough and set the cookies as they bake.
Brown sugar
Adds moisture, caramel flavor, and some browning to the cookies.
Baking soda
Reacts with the dough's acidity to produce gas that helps the cookies rise and spread.

The step that matters

Mix flour in only until the oatmeal is blended. Overmixing once flour is added develops gluten, which can make the cookies tough and dense instead of tender.

Swap the pecans

How well each one fits the dish's main ingredients (oats, sugar, egg, vanilla, flour):

  4. Pecansthe original

Fit is the average pairing score against oats, sugar, egg, vanilla, flour. Candidates are from the same food group and used in at least 100 recipes.
