Spray a crockpot with cooking spray or use a crockpot liner.
In the bowl of a stand mixer (or a large mixing bowl if you’re using a hand mixer), add all the ingredients except the pecans. Whisk at low-medium speed for one minute or until well combined.
Pour pumpkin mixture into the crockpot. Before placing the lid, add a kitchen towel to the top of the crockpot. Do not allow the towel to touch the pumpkin mixture.
Place the lid over the towel, and cook on low setting for 5 hours until the top of the pudding is set and the sides begin to pull away from the crockpot.
Remove lid and towel, and sprinkle the toasted sprinkle pecans over the pudding. Serve warm and enjoy!
