Prepare mayo sauce by adding all ingredients to a blender or food processor and blending until smooth.
In a bowl, add hearts of palm, peppers, green onions, and parsley to the mayo sauce and stir until veggies are fully coated.
Add spices and oat flour (can be store bought or you can make it by blending oats in a blender or food processor until it becomes a powder) to the veggie and mayo mix.
Form crab cakes into patties with your hands and place onto a parchment paper lined baking sheet. This recipe makes 6 cakes that are slightly larger than palm sized, or you can make smaller cakes to serve as an appetizer.
Sprinkle with a little extra nutritional yeast and smoked paprika (optional, but recommended) and bake at 425F for 20 minutes or until golden brown
Notes
These can also be made in an air fryer!
