In the base of a food processor, combine pitted dates, oats, cashews (not soaked), maple syrup, vanilla and spices. Blend on high for 2-3 minutes, stopping the food processor a few times to scrape down the sides as needed. Blend until a dough starts to form, one that stays together when you press it between your fingers.
Add to the food processor the grated carrot, shredded coconut, raisins and chopped pecans. Pulse everything until the carrot cake ingredients are incorporated into the dough.
Turn out the dough into a parchment lined 8x8 inch baking dish. Press the dough down into an even layer. Refrigerate the bars for at least one hour.
To a high speed blender, add soaked cashews, maple syrup, apple cider vinegar, coconut oil, coconut cream, vanilla and sea salt. Blend on high until you have a very smooth consistency, ensuring to scrape down the sides of the blender as needed.
Pour the frosting into a bowl. Cover with plastic wrap, ensuring the plastic wrap touches the top of the frosting and refrigerate for at least one hour.
Cut the bars into 9 equal pieces. Using a rubber spatula, mix the frosting well and then frost the bars with an even layer of frosting. Alternatively, you can frost the bars and then cut them.
