Preheat your oven to 350°F
In a bowl, mix the plant based milk with the apple cider vinegar to curdle and wait a few minutes
Mix in the apple sauce, oil and remainder of the zest+sugar mixture
Incorporate the dry ingredients (flour, baking powder, baking soda, salt and grains of paradise) bit by bit
At this point, your sliced oranges have cooled
In an 8" cake pan lined with parchment paper, layer the cooked orange slices, drizzle a little bit of the syrup from the cooked oranges to fill any empty spaces
Pour in the cake batter
Bake at 350°F for 35-40 mins until a toothpick comes out clean
Let the cake cool down before slicing
Enjoy with a cup of tea or coffee
