Put all ingredients, except apples in food processor and process until well blended. Cake batter will be smooth and creamy. If not, process some more.
There's no need to peel the apples, but core and dice into small cubes. Stir apples, by hand, into cake batter.
Pour mixture into prepared pan.
Bake for 40 minutes. Toothpick should come out clean when inserted into cake. Cool in the pan for 20 minutes. Run a knife along the edge to loosen and then place a wire rack against the top of the pan. Carefully flip. Let cool completely.
If you're making the cake in advance, cool completely and then use plastic wrap to cover tightly, all around. Use a layer of aluminum foil on top of that, if you're freezing.
For the Choclate Drizzle
Remove pits from the dates. If they are dry, soak in warm water for 30 minutes and then completely drain before proceeding.
Place dates, almond milk and cacao into blender or food processor. Blend until smooth and creamy, with thick, but drippy consistency.
Decorate Cake
Place apple cake on serving plate or pedestal.
Use a small spoon to drizzle sauce over top of cake and let it drip down outsides and center.
Notes
Bundt Pan: If you have a tube pan with removable bottom, use unbleached parchment to line the bottom for easy cake removal. If you're using a regular bundt pan, then be sure to liberally grease and flour or spray so you can get the apple cake out more easily. Baking Pan: This cake can also be make in a 9x13-inch baking pan, baked for 30-35 minutes. Check cake at 30 minutes, by inserting toothpick into center. Spread a thin layer of chocolate sauce over the entire cake before cutting into squares to serve. Flour: any all purpose flour will work well, including a gluten-free blend. Milk: I used almond milk. Use your favorite plant based milk.
