Preheat the oven to 400F.
Line a baking dish with parchment paper.
Soak the cashews in hot water for 10 minutes, then drain.
Add the cashews, Willa's Oat Milk, apple cider vinegar, nutritional yeast, garlic powder, salt, and pepper to a blender or food processor. Blend until smooth. Taste and adjust seasoning as needed.
Arrange the baby spinach and artichoke hearts in the baking dish. Pour the cashew mixture over top and stir until well combined. Cover with foil and bake for 15 to 20 minutes, removing the foil halfway through.
Remove from oven. Let cool and enjoy!
