Notes
RECIPE NOTES & TIPSBaking - Be careful not to overcook the slice – it will continue to firm as it cools.Storage - Place the bars in an airtight container and keep in the fridge for up to 5 days. You can also freeze your bars in an airtight container or freezer-safe bag for up to 3 months.Maple syrup notes - You can also use honey or, for a more traditional American recipe, use corn syrup.Size of pecans - I like to use pecan halves for these bars, but you can also use chopped pecans. Whole pecans may be a bit large, but you can try them, if you prefer a thicker top layer!
