Adjust an oven rack one-third up from the bottom of the oven and preheat the oven to 350F degrees. Butter a 9.25 x 5 x 3-inch loaf pan. Or use two or more smaller pans if you with. Dust the pan (or pans) with fine, dry plain bread crumbs and tap over the sink or a piece of paper to shake out excess crumbs.
Sift together 2 cups flour, ¼ cup almond flour, 2 teaspoons baking soda, ½ teaspoon salt, 1 ½ teaspoons cinnamon, and ½ teaspoon cloves. Set aside.
It is not necessary to use an electric mixer for this, although you can if you wish (I don't. I use a large spoon to just stir everything and that is how I will instruct the rest of the recipe.)
In a large bowl, stir 2 eggs lightly to mix. Add 2 cups brown sugar and ½ cup oil and then stir. Mix in 2 cups pumpkin,1 cup dates and 1 cup walnuts. Now add the sifted dry ingredients and stir only until they are smoothly incorporated.
Turn into the prepared pan(s) and smooth the top(s).
Bake for 50-60 minutes in the large pan. If using smaller pans, check them after about 35 minutes. Bake until a cake tester or tooth pick inserted in the middle comes out just barely clean.
Cool in the pan for 15 minutes. Cover with a rack, turn over the rack and the pan. Remove the pan, and then turn the loaf right side up again on the rack. Let cool completely.
If possible, wrap the loaf (loaves) in plastic wrap and refrigerate several hours before slicing. Freezes quite well, also.
