Preheat your oven to 350°F. Spray a 9x13-inch baking pan with non-stick spray.
Add all the ingredients except the dates and nuts to the bowl of your electric mixer.
Mix on low speed for 1 minute then turn up to medium speed for 2 more minutes.
Stop the mixer and scrape the sides and bottom with a spatula. Add the dates and nuts and stir until combined.
Pour the cake batter into your prepared pan. Bake at 350°F for 35 to 40 minutes or until done in the center. To test, use a wooden pick or cake tester. When there are no crumbs or dry crumbs on the pick after being inserted into the cake it's done.
Remove the cake from the oven and cool on a wire rack.
