Place a small saucepan over low heat and melt 1/4 stick of the butter and add the flour to the melted butter. Allow to cook on low for 2 minutes.
Add the milk to the saucepan and bring up to a boil and allow mixture to thicken.
Remove saucepan from the heat and add the Sucanat, cinnamon, salt, and apple butter to the saucepan. Stir well to incorporate all the ingredients.
Transfer the mixture from the saucepan into a clean bowl and allow to cool completely.
Once the mixture has cooled completely, add the remaining butter and vanilla extract.
Use an electric whisk to whip mixture until light and fluffy, 3-5 minutes, until mixture has the appearance and texture of whipped cream. Alternatively, mixture can be whipped by hand.
