In a medium saucepan over medium heat, add a small splash of oil (optional), then saute the minced garlic until fragrant (about 30 seconds to 1 minute).
Add the ketchup, Frank’s RedHot Sauce, apple cider vinegar, brown sugar, molasses, Worcestershire sauce, onion powder, chipotle powder, salt, and pepper. Stir to combine.
Bring the mixture to a simmer. Reduce the heat to low and let it cook for about 10–15 minutes, stirrin occasionally. The sauce should slightly thicken.
Turn off the heat and immediately whisk in the cold, cubed butter. This gives the sauce a smooth and rich finish.
Taste the sauce and adjust the seasoning if needed (more chipotle for heat, more sugar for sweetness, etc.)
Let the sauce cool before transferring it to a jar or airtight container. Store in the refrigerator for up to 1 week.
