Substitutions
Use old-fashioned (rolled) oats or quick oats for a softer texture. Steel-cut oats are not recommended unless they are pre-cooked. For a different flavor, swap peanut butter for almond or sunflower seed butter (if avoiding nuts).
How to make Oat Bars with Peanut Butter
Step 1 – In a small saucepan, combine 1/2 cup creamy peanut butter and 1/3 cup honey. Warm over medium-low heat, stirring until the mixture is melted and smooth.

Step 2 – Remove the pan from heat and stir in 1 1/2 cups uncooked oats and 1/2 cup chocolate chips until everything is evenly coated.

Step 3 – Press the mixture into a greased 6-inch square pan, using a spatula or the back of a spoon to create an even layer. Sprinkle additional chocolate chips on top if you like.
Step 4 – Let cool to room temperature, then cover and chill in the refrigerator for 1 hour. Once firm, cut into bars or squares and serve.

Pro Tips
- Use creamy peanut butter for an even texture. Natural peanut butter can be used, but stir well before measuring.
- Adjust the honey slightly if you prefer a sweeter or less-sweet bar.
- Press the mixture firmly into the pan to ensure the bars hold together when chilled.
- Store leftovers in an airtight container in the refrigerator for up to one week.
