β Coconut Oil (Refined) (Best Gluten-Free Option)
1:1 (1 cup refined coconut oil per 1 cup butter)Refined coconut oil has a fat content similar to butter and solidifies at room temperature, which helps maintain cookie structure. It contributes to a crisp edge and tender crumb due to its saturated fat profile.
Ensure the coconut oil is solid but pliable when creaming with sugar to incorporate air properly. Avoid using melted oil directly, as it can cause excessive spreading.
The final cookies will have a slightly different mouthfeel and a mild coconut undertone, but the texture will be close to butter cookies with a crisp exterior and chewy center.
