Step 1

Wash, peel, and slice peaches. Set aside. See note below for using canned or frozen peaches.

Step 2

Add brown sugar, granulated sugar, cornstarch, cinnamon, and salt (optional). Whisk together. It's okay if there are a few small lumps.

Step 3

Add water and lemon juice. Cook over medium heat until thickened, whisking frequently. It will take about 5-7 minutes. The sauce should be thick enough that when you drag a whisk or spoon through the sauce it leaves a streak.

Step 4

Add sliced peaches. Continue cooking and stirring over medium heat for 2-3 more minutes.

Step 5

Remove from heat and add vanilla.
