Tips for Perfect Copycat Oatmeal Creme Pies
To achieve the best copycat oatmeal creme pies, avoid overbaking the cookies. They should look slightly underdone in the center when removed from the oven, as they will continue to set while cooling.
Resting the dough is essential. This allows the oats to absorb moisture, creating a softer and more cohesive cookie.
For even assembly, match cookies by size before adding the filling. This ensures a balanced sandwich and prevents uneven edges.
