Add the granulated sugar to a saucepan. Place the saucepan over medium heat, stirring occasionally with a rubber spatula. As the sugar heats, you'll notice it starting to stick and clump at the bottom. This process usually takes around 3-5 minutes.

Continue stirring until the sugar fully melts and turns a beautiful golden brown. This caramelization process is essential for getting that perfectly rich caramel brûlée flavor and color.

Once your sugar is an amber caramel color and all the sugar has turned to liquid, grab a whisk, remove the pan from the heat, and immediately add the salted butter to the saucepan. Expect a bit of intense bubbling, and just keep mixing until the butter is entirely melted and incorporated.

Once the butter is incorporated, pour in the heavy cream. Again, expect some intense bubbling, and mix it well to ensure a smooth consistency throughout.

Add in the vanilla extract and sprinkle in the flaky sea salt. Stir thoroughly, making sure everything is well combined.

Transfer your Homemade Starbucks Caramel Brûlée Sauce into a mason jar or an airtight container. Allow it to cool down for about 1 hour at room temperature.

Once cooled, seal the jar with a lid and place it in the refrigerator. Your sauce will continue to thicken over time and can be stored for up to 3-4 weeks.

When you're ready to indulge, simply run the container under warm water for 1-2 minutes to soften the sauce or place the amount you'd like to use in the microwave for 30 seconds to soften, and then drizzle directly into your favorite drinks, onto desserts, or even straight into your mouth, no judgement here!
