- For the most authentic Crumbl key lime pie cookies, use fresh key lime juice and zest for a brighter, more vibrant citrus flavor.
- Finely crush graham crackers to achieve a smooth cookie texture that still delivers that classic key lime pie crust taste.
- Avoid overbaking—slightly underbaked centers keep these cookies soft, thick, and bakery-style just like Crumbl.
- Chill the dough if needed to prevent spreading and maintain that signature oversized cookie shape.
- The cream cheese frosting should be fully smooth before adding lime juice to avoid a runny consistency.
- Store cookies in the refrigerator due to the cream cheese frosting, but allow them to sit at room temperature before serving for the best flavor and texture.
- These cookies are perfect for spring and summer dessert recipes, especially for parties, holidays, or citrus dessert lovers.

Step 3: Shape the Cookies
- Scoop large dough balls (about 1/3 cup each) and roll them smooth. Slightly flatten each cookie to create a thick disk.
Step 4: Bake
- Bake at 350°F for 10–12 minutes until edges are set and centers remain soft. Allow cookies to cool completely before frosting.
Step 5: Make the Frosting
- Beat cream cheese and butter until smooth and creamy. Add powdered sugar gradually, then mix in key lime juice, zest, and vanilla extract until fluffy.
Step 6: Assemble
- Spread or pipe frosting generously onto each cooled cookie. Top with whipped cream, lime slices, graham crumbs, and extra zest.
