Once upon a time, when my boys were young and in Little League, we did a lot of eating on the run. The slow cooker helped us manage meals, but people were hungry during those games and seemingly never-ending practices.

Granola bars were my go-to grab and go snacks. I chose what I thought were the healthiest bars, but not long into the season I realized that 1. we were creating a lot of trash and 2. we were spending a lot of cash.

Time to learn how to make granola bars myself!

These peanut butter granola bars, adapted from a recipe from a vintage television show called Zoom (remember THAT?), became our standby snack on busy days.

Ingredients

Oats The bulk of this granola recipe comes from old fashioned rolled oats. Skip the quick oats; you want the heft of whole, rolled oats here.

Honey This recipe is lightly sweetened with honey. If you like, you could easily use maple syrup instead.

Peanut Butter Added for both flavor and a little extra protein, peanut butter helps hold the ingredients together, too. I prefer a natural peanut butter; opt for creamy peanut butter or crunchy peanut butter. For a nut free version, try sunflower seed butter or use melted butter or coconut oil.

Eggs — Fresh eggs, store bought, use what you have readily available.

Optional Add-Ins This is where you can really customize these homemade granola bars. We typically add raisins or dried cranberries, along with mini chocolate chips and nuts. You can also add unsweetened shredded coconut.

Making Them

Start by mixing the peanut butter, honey, vanilla, and eggs in a bowl. Add the remaining ingredients and stir to combine.

Transfer oat mixture to a rimmed baking pan and spread evenly. Use a spatula or your hands to press the mixture firmly into the pan.

Bake, remove from oven, and once again press the oat mixture firmly into the pan. Doing this both before and after baking the bars helps them retain their shape.

Cool, then cut into bars.

Storage

Place bars into an airtight container. Store at room temperature for up to a week.
