Line an 8x8 baking dish with parchment paper or spray with cooking spray.
In a bowl, or in the 8x8 baking dish, mix together the peanut butter and honey until smooth.
Add the oatmeal to the peanut butter and honey. Stir until smooth.
Press the mixture into the 8x8 dish with a spatula or your hands until it is flat. If desired, melt chocolate in the microwave and drizzle over the peanut butter bars.
Place the bars in the freezer for 10-15 minutes or until the bars are set and firm. Cut into squares and enjoy!
