Scientists have studied the ideal amount of time for dunking an Oreo in milk. Turns out, there is a right way and a wrong way to accomplish the deed for maximum results.
In 1998, a professor at the University of Bristol in the UK looked into the ideal method for dunking a British biscuit (aka “a cookie”) into a drink, using the concept of capillary action — the way fluids move spontaneously through small tubes in porous materials — and Washburn’s equation, which describes their journey. Eventually, he determined that the typical British biscuit is best dunked for 3.5 to 5 seconds.
Using this same technique in 2016, scientists at the University of Utah’s Splash Lab determined the perfect dunk time for the much-beloved Oreo. Although the amount of time to get to “perfect” depends on preferred sogginess levels and milk-fat content, the Utah researchers determined that 3 seconds was enough to thoroughly saturate the Oreo without losing structural integrity.
Here’s the journey in slow motion. Cookies are porous. Milk travels through the small holes inside them the same way ink does through blotting paper — or a spill through a paper towel. During tests, the Oreo soaked up 50% of its potential liquid weight in 1 second. That number shot up to 80% at 2 seconds, flatlined at 3 seconds, and maxed out at 4 seconds — meaning the cookie could absorb no more milk. So if the goal was to saturate the cookie but not lose structural cohesion, 3 seconds was the perfect number.
While this test used 2% milk as its dunking medium, the optimal dunking time will vary slightly when using other milk. The higher the milk fat (like whole milk or cream), the longer a cookie can be dunked, but only by mere fractions of a second.
And now you know. Happy dunking!
