The typical batch of oatmeal cookies

Every recipe, ingredient by ingredient

Each dot is a recipe, placed by grams of the ingredient per 100 g of flour (100% would be as much as the flour). The shaded band is the middle half of recipes and the line is the median.

  1. Oats

    median 85% · most 64 to 122%

    Oats absorb moisture and give chew; recipes with more oats than flour are hearty and thick, fewer make a cookie closer to chocolate chip.

    Each dot is up to 7 recipes.

    range 30 to 250%

  2. Fat

    median 91% · most 74 to 116%

    Butter controls spread and richness; melted butter gives a chewier, flatter cookie than creamed.

  3. Sugar

    median 135% · most 115 to 168%

    Oatmeal cookies lean on brown sugar, whose molasses keeps them moist and chewy.

  4. Egg

    Egg holds the oats together; an extra yolk makes a chewier cookie.

Where recipes disagree

Measured by how far apart the 25th and 75th percentile recipes are. The widest gaps are where the choice of recipe matters most.

  • Salt. The middle half of recipes use 1 to 2.1% of the flour weight in salt, so a recipe at the 75th percentile has 2.2 times as much as one at the 25th.
  • Oats. The middle half of recipes use 64 to 122% of the flour weight in oats, so a recipe at the 75th percentile has 1.9 times as much as one at the 25th.

Recipes agree most on sugar and fat: sugar 115 to 168%, fat 74 to 116% for the middle half.

Around the world

495 of the recipes come in 6 languages with enough of each to compare: English 411, French 28, German 19, Portuguese 16, Spanish 11, Dutch 10.

  • Dutch recipes use about half as much fat as English ones (39% against 91% of the flour weight), 30% less sugar (100% against 144%) and under a third as much salt (0.4% against 1.6%).
  • Spanish recipes use 26% less sugar than English ones (105% against 144% of the flour weight) and about half as much leavening (1.3% against 3%).

What the words in titles mean

English recipes whose titles use a word, against the ones that do not. What recipe writers do when they pick the word, not proof that it makes the texture.

Recipes called “chewy” (38), “best” (16) or “soft” (14) use about the same amounts as the rest on every ingredient measured here.

The most-reviewed recipes

84 oatmeal cookie recipes have 50 or more reader ratings. A rating count says how many people rated a page, which follows its traffic more than its quality. Against the other 415, medians per 100 g of flour, compared within each language:

On no ingredient do the most-reviewed recipes differ from the rest by more than chance would explain.

  • 350°F331 recipes
  • 375°F70 recipes
  • 400°F18 recipes
  • 325°F9 recipes
  • 300°F5 recipes
  • 365°F4 recipes

480 recipes state a bake time. Taking the middle of any stated range (“55 to 65 minutes” counts as 60), the median is 11 minutes and the middle half bake 10 to 14 minutes.

Temperature and time together

The single most common pairing is 350°F for 10 to 12 minutes, with 127 of the 431 recipes that state both.

Rows: oven °F (°C in gray), every 25°F. Columns: minutes, 2 a column, from the start of each; the middle of a stated range counts. Darker: more recipes, up to 127 in one cell. Outlined: the median, 350°F for 11 minutes. 431 recipes state both. The edge rows and columns also hold the few recipes beyond them.

In 7 languages: English 411, French 28, German 19, Portuguese 16, Spanish 11, Dutch 10, Italian 4. Lines in other languages are read in their own units and words, and each recipe page links to the original. 121 sites in all. No site contributes more than 12 recipes.

How the numbers are made

Every ingredient line is converted to grams and grouped (butter and oil count as fat; white, brown and liquid sweeteners as sugar), then divided by the flour weight. That baker's percentage is the only comparison that holds across recipes of different sizes.

99% of the 5,712 ingredient lines got a weight. 25% of those weights were printed by the source; the rest were converted from cups and spoons with standard densities, so treat single recipes as close, not exact. Frosting, glaze, streusel and other toppings are listed on each recipe page but left out of the percentages.

A recipe outside the plausible range for any ingredient is left out rather than allowed to stretch every chart; it is usually a different dish with the same name or a misread line. Of the pages fetched, 472 were left out: 242 outside the plausible range on some ingredient (oats 136, fat 52, leavening 25, salt 13, sugar 9, egg 7), 155 with no flour, or none that could be weighed, 49 with a title that names a different dish, 9 over the 12-per-site cap, 8 duplicates of other pages, 5 made from a boxed mix, 3 with an ingredient in amounts that could not be weighed, and 1 too many lines without an amount.

Every recipe page links to the original, which is where the method is. Recipe Lab does not republish instructions or photos.
