⭐ Unsalted Butter (Best Gluten-Free Option)
1:1 (1 tablespoon butter per 1 tablespoon coconut oil)Butter works well because it has a comparable fat content and solid state at room temperature, which helps maintain the structure and mouthfeel of tiramisu. The milk solids in butter add a subtle depth of flavor that enhances the dessert.
For best results, use unsalted butter to control salt levels and soften it to room temperature before incorporating. Avoid melting it fully to preserve the texture.
Compared to coconut oil, butter provides a more traditional dairy richness that aligns well with tiramisu’s mascarpone and cream components, making it the closest match in both texture and flavor.
