- Line your 8x8-inch baking pan with parchment paper, allowing some overhang on the sides for easy lifting later. 
- In a large mixing bowl, combine the creamy peanut butter and honey. If the peanut butter is too thick, warm it slightly in the microwave for 20-30 seconds to soften. Stir until smooth and fully blended. 
- Add vanilla extract and salt to the peanut butter and honey mixture. Stir well to evenly distribute. 
- Gradually fold in the rolled oats and powdered sugar. Mix gently but thoroughly until all oats are coated and the mixture starts to come together. 
- Add the dark chocolate chips and fold them into the mixture. Reserve a small handful to sprinkle on top later. 
- Spoon the mixture into the prepared pan and press down evenly using the back of a spatula or your fingers to compact well. 
- Sprinkle the reserved chocolate chips over the top and gently press them into the surface. 
- Place the pan in the refrigerator for at least 2 hours, or until bars are firm enough to cut. 
- Use the parchment paper overhang to lift the bars out of the pan. Cut into squares or rectangles and enjoy.
