These homemade granola bars are much better than what you can buy at the store, especially since you can substitute for your favorite dried fruit or nuts. You need to chill the bars for at least 2 hours before cutting them.
Preheat the oven to 350°F. Line the bottom and sides of an 8-inch or 9-inch square pan with aluminum foil or parchment paper.
Combine the butter, honey, brown sugar, vanilla extract, and salt in a small saucepan over medium heat. Cook, stirring occasionally, until the butter melts, the mixture bubbles, and the sugar dissolves.
Store granola bars in an airtight container for a few weeks in the fridge. For the softest bars, keep them in a cool area of your kitchen (like a dark pantry). For firmer bars, store in the fridge. Bars will keep in the freezer for up to three months when wrapped well.
