Here's how to make it so you can enjoy it yourself, I mean, your kids can enjoy it.
In a saucepan melt 1/2 cup butter.
Add 1 cup brown sugar and whisk until combined and thickened, about two minutes.
Whisk in 2/3 cup whipping cream until thoroughly combined, about two more minutes.
Mix in 1 teaspoon vanilla.
Isn't that easy? The note on the recipe says it will thicken more when refrigerated, but mine didn't. But it doesn't matter, it tastes so yummy, we haven't minded that it is more liquid in form.
