Add the butter, sugar, salt, and water to a medium pot over medium heat and bring to a boil. Stir occasionally. Once boiling, cook for 1 full minute while stirring frequently.
After 1 minute, turn heat to medium low and simmer for 5 minutes, stirring frequently. Remove from heat, let stand for 5 minutes, then stir in extract, adding to taste (Add slowly, starting with 1 teaspoon—it’s always easy to add more!).

Notes
Note 1: Maple extract can be found among the other baking extracts in the grocery store. I recommend McCormick’s® pure maple extract for the best and purest flavor (not sponsored). Add maple extract to taste; intensity will vary depending on the brand you use.Storage: Serve over your favorite breakfast recipes or let cool and store for future uses. Syrup will store well for 1–2 months in an airtight container in the fridge.
