Less isn't always best. Especially when it comes to food. I used to be in your shoes, too, thinking multiple small meals throughout the day would help me "control my weight". And ya know, for some people it works. But for most humans, finding time to eat 6x/day seems about as doable as nailing jello to a tree. Some of you are lucky to find time to eat breakfast. Ultimately, if you are a person that falls in any of the categories of full-time employee, mom, dad, or caregiver, eating 3x/day is about as much time as you can offer without working at your desk while plowing through a leftover burrito. So, this is why I'm suggesting to eat more than a single cookie.
If you're hungry and you want a cookie, eat the cookie. But eating a single cookie isn't going to be filling and you'll likely feel like you could eat 4 more. By creating a meal or substantial snack around the cookie, you could concoct a mixture of Greek yogurt, your favorite cookie, some nuts, and some berries of choice. This way you're creating a well-rounded snack that provides protein (Greek yogurt), carbs (cookie), fat (cookie + nuts), and fiber (berries). Now you might be thinking, "well, that's more calories than the single cookie!" You're right. It is. But if you're hungry and you eat a single cookie, I promise you're going to be hungry again in 30 minutes. And at that point, maybe you'll grab more cookies or maybe you'll grab something else. Eating something slightly more calorically dense and with more nutritional properties will keep you satiated and fuller for longer. So next time, don't be afraid to whip up a yogurt bowl or another concoction out of a cookie. PS, this doesn't just go for cookies. You could apply this to anything sweet or savory. Hankerin' for some chips? Build a nacho bowl with your protein of choice, beans, salsa, and gauc. Okay, now that I'm salivating, go have yourself a snackaroo.
