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.

recipe details
You'll love that there's just a few simple steps for my baked peanut butter oat bars recipe.
Preheat the oven and coat a 9 x 9 inch silicone baking pan with cooking spray. This is my go to pan for these tasty oat bars. They slide out so easily.
Grab a large bowl and add rolled oats, chocolate chips, salted peanuts, peanut butter, sweetened condensed milk and cinnamon. This is a thick mixture so use a sturdy spatula to mix the ingredients.
Spread the oat mixture into the prepared pan. Make sure its pressed down and evenly fills the pan.
Bake the bars until firm to the touch and light brown on the edges. Cool in the pan and then flip out the on to a cutting board. Cut into squares.
Store the bars in an air tight container for up to a week or freeze for up to 2 months.
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.
variations
Peanut butter chocolate chip oat bars are my all-time favorite flavor combination. But I do change up the ingredients to make more tasty bars. Here's some variations to try.
- Almond butter, dried cranberries and chocolate chips
- Cashew butter, salted cashews and butterscotch chips
- Sunflower butter, pecans and chopped dried apricots
- Peanut butter, raisins and white chocolate chips
