Layer 1: Mix the pecans that are chopped with flour and butter. Take a pan that could be of your choice but I suggest a 9x9 pan. Spray oil so the mixture does not stick to it. Bake it for 15 minutes at 350 degrees and let it cool.
Layer 2: In a bowl add the cream cheese, sugar, 1 cup of whipped cream, and blend it with a beater. Let it cool and add it to the top of the crusty pecan layer.
Layer 3: Mix milk. Pudding mix, canned pumpkin, and the spice and heat it on high flame. Now, turn down the flame and add whipped cream topping to smooth it out. Let it cool and then spread it over layer 2.
Layer 4: Use the remaining whipped cream and add the pecans to it. Add it as the 4th layer.
