Homemade granola bars that fall apart when you pick them up were either not pressed into the pan firmly enough before setting, or they were cut while still warm, when the binder has not yet hardened. Both problems are easy to fix and the result is a bar that holds together through a lunchbox.
The Binder and Why It Works
The combination of honey and nut butter heated together is what binds oats and mix-ins into a bar that holds its shape. Honey provides the sticky adhesive, and the nut butter adds fat that coats the oat surfaces and helps everything stay cohesive when cooled. The mixture needs to be heated together until it is fluid enough to coat every oat, this requires bringing it to a gentle boil and stirring for 90 seconds. An under-heated binder stays thick and does not distribute evenly, which leaves dry pockets that fall apart.
The Recipe
Toast 2.5 cups of rolled oats in a 350°F oven for 8 minutes until lightly golden. In a saucepan, combine a third cup of honey and a third cup of peanut butter or almond butter over medium heat. Bring to a gentle boil stirring constantly, then cook for 90 seconds. Pour over the toasted oats and mix-ins, chocolate chips, dried cranberries, sunflower seeds, or any combination, and stir until every oat is coated.
Transfer the mixture to an 8×8 pan lined with parchment paper. Press very firmly using the bottom of a flat glass or a measuring cup, the harder you press, the better the bars hold together. Pressing once is not enough. Press in sections, pressing down with full body weight for 10 seconds on each section until the mixture is dense and compact. Refrigerate for at least 2 hours or overnight before cutting.
Cutting and Storage
Lift the entire slab out of the pan using the parchment paper overhang. Cut on a cutting board with a sharp knife using a pressing-down motion rather than a sawing motion. Store in the refrigerator where they keep for 2 weeks, or individually wrapped in the freezer for 3 months. At room temperature they soften slightly but hold together well for lunchboxes if kept cool. Rolled oats and mix-in options are available on Amazon in bulk.
