In a large skillet, over low to medium low heat, melt your butter. When it is starting to change color, add the brown swerve.
Do not allow the butter to get too dark. Mix and then pour the butter and swerve mix into a small container. I used a measuring cup. I removed as much of the butter/swerve mixture as possible.
Sprinkle the allulose over the skillet.
Basically you are melting the allulose and wanting it to turn golden.
This is the color you are looking for.
Whisk until combined. Add the heavy cream. It will bubble.
You want the color to get nice and golden, it won't take long at all. Add the vanilla and pour into a small glass container.
This makes about half or so of a jelly jar.
