This creamy butterscotch sauce is perfect for drizzling over desserts or adding a rich flavor to your favorite treats.
Combine the brown sugar and butter in a saucepan over medium heat.
Stir constantly to ensure the sugar dissolves evenly and doesn't burn.
Once the mixture begins to bubble, reduce the heat to low and stir in the heavy cream.
Add the cream slowly to prevent splattering and ensure a smooth consistency.
Cook the mixture for another 5 minutes, stirring continuously.
The sauce will thicken as it cooks; adjust the heat to prevent it from boiling over.
Remove the saucepan from heat and stir in the vanilla extract and salt.
Adding vanilla off the heat preserves its flavor.
Let the sauce cool slightly before transferring it to an airtight container for storage.
The sauce will thicken further as it cools, so don't worry if it seems a bit runny initially.
