Preheat oven to 375° F. Core pears or apples and slice in half (leaving skin on). Place face down in baking dish. Add ~1/2 cup water to the bottom of the baking dish, cover and place in the oven for 50 minutes, removing the covering for the last five minutes to add cinnamon and drizzle agave nectar over the fruit.
While the fruit is baking, place cashews in a food processor. Blend while slowly drizzling water to desired consistency.
When the fruit has finished baking and is soft but not mushy, remove from the oven, place a heaping spoonful of the cashew cream onto each piece of fruit and serve warm.
