Before bed, pre-heat your oven to 180 degrees Fahrenheit.
​Pour four cups of cream into the glass pan.
Place it in the oven and allow it to bake for 12 hours.
The next day, remove it from the oven and allow it to cool to room temperature.
You will notice the thickened cream is on the top. It may have an almost flakey layer that is yellow or golden brown.
Once cooled, place it in the fridge for eight hours.
Next, use spoons to scoop the thick surface layer from the milky bottom layer.
Keep that leftover liquid for use in other recipes or even just for drinking.
Place the scooped cream into your storage container or a mixing bowl.
Stir to your desired consistency, adding back in the milky liquid if it is too thick.
Keep it in an airtight container in the fridge and use within a week.
