rolled oats
natural peanut butter
honey or maple syrup
eggs
vanilla extract
baking soda
salt
dark chocolate chunks or peanut butter chips
chopped peanuts (optional)

Directions

I start by preheating the oven to 350°F (175°C) and lining a baking dish with parchment paper.

In a large bowl, I mix the peanut butter and honey until smooth. I beat in the eggs and vanilla extract.

I stir in the rolled oats, baking soda, and salt until everything is evenly combined. I fold in the chocolate chunks and chopped peanuts if I’m using them.

I press the mixture evenly into the prepared baking dish and smooth the top. I bake for about 18 to 22 minutes, until the edges are set and the center is lightly golden.

I let the bars cool completely before slicing into squares.
