First created in the Dutch city of Gouda (that’s right, that Gouda) sometime near the turn of the 19th century, Stroopwafels (literally syrup waffles in Dutch) have since become a certified national treasure of the Netherlands, and are now a curiously caramel-y staple of the Trader Joe’s holiday lineup. They’re made by pressing waffles made from a dense, flavorful batter in a hot iron, then quickly slicing those waffles in half while they’re still hot, and sandwiching sweet, stretchy caramel in between each slice. The resulting cookie is a uniquely delicious experience, especially when enjoyed in the traditional Dutch way: place a Stroopwafel over a hot cup of coffee or tea, and let the steam gently soften the caramel inside to a perfect level of gooeyness.
