Line a 9 x 9 pan with parchment paper and set aside.
In a medium sauce pan over medium low heat, melt together the peanut butter and maple syrup. Stir until it is smooth and well combined, about 5 minutes.
Remove from heat and stir in the vanilla and salt.
Add in the oats, 1/2 cup at a time, stir well, and then stir in the ground flax and pumpkin seeds (save a tablespoon of pumpkin seeds to press into the top for a pretty bar!). The mixture will be thick and takes a bit of effort to really combine it well.
Dump the mixture into the center of the prepared pan, and, using a spatula, flatten it out and press it down really well. Press it in really hard to help the bars really hold together well.
Sprinkle the chocolate chips and the reserved pumpkin seeds on top and using your finger, press them down.
Place the dish in the fridge for 30-45 minutes to set. Once firm, slice into bars or squares.
