Toast the oats: Preheat the oven to 350 degrees Fahrenheit. Place the oats in a single layer on a baking sheet and toast them for 10 minutes until lightly golden. (This step adds incredible toasty flavor to the oats: don’t skip it!)
Mix the ingredients: Transfer the oats to a large bowl and mix in the peanut butter, honey, oats, salt and cinnamon in a bowl. Stir in 1/4 cup of the chocolate chips.
Form into bars: Add a sheet of parchment paper to a 9″ x 9″ pan, letting the edges drape over the sides. Place the mixture into the pan and press it into an even layer. Add the remaining 1/4 cup chocolate chips to the top of the bars. Use a small glass to roll over the top to make them as smooth as possible.
Freeze and cut the bars: Freeze the bars for 10 minutes. Then remove the pan from the freezer and use the parchment to lift the bars out of the pan. Use a sharp knife to cut them into 14 bar sized shapes (that are 4 ½ by 1 ¼ inches), or the size of your choice. Store in the refrigerator for up to 3 weeks. The texture becomes solid after refrigerating for 2 hours, so if you have time do that before tasting the first bar.
