Keeping in line with speedcooking, the hands-on portion of this recipe is done in about 5 minutes and they're out of the oven in 30. Speaking of out of the oven, if you eat them still warm from the oven, you'll be in total heaven.
Preheat oven to 350 degrees. Line a 9x9 pan with parchment paper.
If using a food processor, add the flour, oats, sugar, butter, 1/2 teaspoon cinnamon, and baking soda to the bowl fitted with the dough blade. Process in 10 second bursts until you have a crumbly mixture with small dots of butter throughout. If using a pastry cutter, add mixture to a small bowl and cut together until you have a crumbly mixture with small dots of butter throughout.
Spread half of the mixture into the prepared pan and press to flatten.
Stir together the pumpkin, maple syrup, remaining 1 teaspoon of cinnamon, nutmeg, and ginger until combined. Spread gently over the oat mixture.
Sprinkle remaining oat mixture over the top.
If baking in a convection oven, bake for 28 minutes or until golden brown and edges are holding together. If baking in a standard oven, bake for 35 minutes or until golden brown and edges are holding together.
Serve warm or at room temperature - bars will be fairly soft and crumbly and are easiest eaten with a fork.
