Preheat oven to 350 degrees and grease an 8x8 pan/baking dish
Mix your oatmeal, protein powder, cocoa powder, pumpkin pie spice, psyllium husk powder in a bowl until combined.
Add pumpkin and mix
Add liquid of choice until a thick batter is formed. Fold in chocolate chips (or leave out and top bars with them instead before placing pan into oven)
Place batter into the greased baking dish/pan and into the oven for about 25 minutes or until it comes clean with a toothpick
Slice into 12 bars and place on a cooling rack
Keep leftovers in the fridge in an airtight container.
The amount of liquid needed will depend on how absorbent your protein powder is and how much psyllium you use.
These bars are great cold as well, leave them in the fridge for a few hours to firm up and get nice and dense!
