Using the fine shredding attachment on your food processor, shred the carrots. (Alternatively, use a hand grater) Put in the S-blade and then add the walnuts, almonds, and dates. Process until everything is broken down and you have a crumbly mixture. Add the oats, raisins, pineapple, maple syrup, and spices and pulse until everything is well mixed. (Alternatively, you can chop the nuts and dates by hand and then mix in the rest of the ingredients. The texture may be slightly different, but it should still work. Disclaimer: I have not tried this.)
Line an 8X8 inch pan with parchment paper or lightly oiled tin foil. Press the carrot mixture into the pan. Put it in the freezer to help it set while you are making the frosting.
Rinse out the food processor and put the S-blade back in. Add the cream cheese, vanilla, and stevia and process until it is just mixed. Don’t over process.
Use a spatula to put the frosting on top of the carrot cake bars. Cut into the size you desire. These need to be stored in the fridge because there is no sugar in the cream cheese. Enjoy!
