How to Store Flourless Chocolate & Olive Oil Mousse Cake

Quick answer

To keep your flourless chocolate and olive oil mousse cake fresh, store it in an airtight container in the refrigerator for up to 5 days, and bring it to room temperature before serving for the best flavor.

Step-by-step storage guide

1. Cool completely before storing: If the cake is freshly baked or just delivered, let it cool to room temperature on a wire rack. Storing it while warm creates condensation, which can make the surface soggy. Always cool before covering.
2. Wrap or place in an airtight container: Wrap the cake tightly in plastic wrap or place it in an airtight container. This prevents it from absorbing odors from the fridge and keeps it from drying out. Make sure the wrap touches the cake surface to minimize air exposure.
3. Refrigerate for up to 5 days: Store the wrapped cake in the refrigerator. It will stay fresh for up to 5 days. Beyond that, the texture and flavor start to decline. Label the container with the date to track freshness.
4. Bring to room temperature before serving: Remove the cake from the fridge 20–30 minutes before serving. This softens the mousse texture and lets the chocolate and olive oil flavors come through. Don't skip this step—serving straight from the fridge masks the taste.
5. Freeze for longer storage: To store for more than 5 days, wrap the cake (or individual slices) in plastic wrap and then in foil, and freeze for up to 2 months. Thaw in the refrigerator overnight before serving. Freeze slices separately for easy single servings.

Product storage notes

• Flourless Chocolate & Extra Virgin Olive Oil Mousse Cake: This flourless chocolate and olive oil mousse cake is dairy-free and made with dark chocolate and extra virgin olive oil. Because it contains no dairy, it is less prone to spoilage, but the olive oil can oxidize, so airtight refrigeration is still important.
