How to Make Crumbl Buckeye Brownie Cookies: A Quick Look
Start by creaming the butter with both sugars until light and fluffy. Add the egg and vanilla to create a smooth, rich batter.
Fold in the dry ingredients until the dough is thick and chocolatey. Scoop generous portions onto a baking sheet, gently flatten, and bake until just set.
While the cookies cool, whip up the peanut butter fudge layer. Top each cookie with a ball of the fudge and press gently. Finish with a swirl of melted chocolate on top for that classic buckeye cookie flair.
Tips & Tasty Twists for Crumbl Buckeye Brownie Cookie
For extra richness, try using dark chocolate chips for the drizzle instead of semi-sweet. If you’re a fan of crunch, consider folding in chopped roasted peanuts or crushed pretzels into the peanut butter layer.
Chilling the cookie dough for 15–30 minutes before baking can help enhance the fudgy texture even further. And don’t skip the cooling time—these cookies firm up beautifully as they rest.
If you’re baking for a crowd, you can double the recipe and shape the cookies slightly smaller for more servings. They’re irresistible for game days, holidays, or any sweet craving.

Keep ‘Em Fresh: How to Store Crumbl Buckeye Brownie Cookies
These cookies store well at room temperature in an airtight container for up to four days. For longer freshness, refrigerate them for up to a week, especially if you like a firmer peanut butter layer.
You can also freeze the cookies, either frosted or unfrosted, for up to two months. Thaw them overnight in the fridge and let them come to room temperature before serving for the best texture and flavor.
