Hey guys! I've got a oat snack bar recipe that is so delicious and easy make. I'd tuck these baked oatmeal bars into my kids' track bag or softball backpacks to stave off any late day energy slump.

After a while, their friends would ask for any extras of the peanutty and chocolate chip bars. I've made so many batches of oat bars for family, friends and personal chef clients that I can make them in my sleep.

why I love oat bars

After trying dozens of recipes, this baked oat bar one is my favorite. It's got lots of hearty oats, double the peanut with both peanut butter and salted peanuts, and chocolate chips sprinkled throughout.

The tricky part of the recipe was finding the right binder. More times than not, my attempts at granola bars came out as more of a crumble. The sweetened condensed milk is the ideal binder. It's the key to sturdy and chewy bars that hold their shape and aren't sticky.

To make the oatmeal bars easily portable, I package them in these self sealing cellophane bags. I always make a double batch. Some are tossed in the freezer (they can be frozen for up to 2 months). The rest are stay fresh for a week when stored in an air tight container.

suggestions and recipe tips

A 9 x 9 inch silicone baking pan is my first choice when making oatmeal bars. There's no need to line the pan with parchment paper as the bars slide right out.

For oat bars uniform in size and thickness, firmly and evenly press down the oat mixture in the baking pan.

To easily cut the bars into squares, place the completely cooled, unmolded and uncut oat bars on a cooling rack. Let sit for about 4 hours at room temperature. This allows the chocolate chips to harden and the bars to firm up.

Cashew butter, salted cashews and butterscotch chips
Sunflower butter, pecans and chopped dried apricots

3 ¼ cups rolled oats
1 cup semi sweet chocolate chips
1 cup salted peanuts
⅓ cup creamy peanut butter
1 14-ounce can sweetened condensed milk
1 teaspoon cinnamon

Instructions

Preheat oven to 250 degrees F. Coat a 9 x 9 inch silicone baking pan with cooking spray. If using a 9 x 9 inch metal baking pan, coat with cooking spray. Line with parchment paper letting the the side edges overhang by 2 inches. Coat the parchment paper with cooking spray. Set aside.
In a large bowl, add the rolled oats, chocolate chips, peanuts, peanut butter, sweetened condensed milk and cinnamon. Stir until the ingredients are will combined.
Spread the oat mixture into the prepared pan. Press down so that the top is smooth and evenly fills the pan.
Bake for 45 to 50 minutes. The bars should be set and light brown on the edges.
Remove from the pan from the oven and place on a cooling rack. Let the bars cool in the pan for at least 1 hour.
If using a silicone pan, flip over onto a cooling rack. If using a metal baking pan, use the parchment paper to lift the bars from the pan and flip over on a cooling rack. You want the bottom side of the bars facing up. If the bottom of the bars is sticky, let air dry for about an hour or so.
Cut into 16 bars. Store in an airtight container or wrap individually in cellophane bags. Store at room temperature for up to a week or in the freezer for up to 2 months.
