Preheat the oven, including a 9.5 inch (24 cm) cast iron skillet (or 2 small skillets), to 356 °F (180 °C).
Sift the flour, baking powder and baking soda into a bowl. Add salt and sugar and mix everything together.
Combine plant milk, applesauce, vanilla extract and apple cider vinegar in a measuring cup. Then pour into the flour mixture and mix briefly until smooth.
Remove the preheated pan from the oven with oven gloves. Melt the butter in it and spread it evenly.
Pour the batter into the pan. Toss frozen berries in cornstarch, then spread evenly on the batter.
Bake the pancake for 30-35 minutes, or until the edges are golden brown and a chopstick comes out clean.
Then remove from oven and garnish with desiccated coconut, fresh berries and pomegranate seeds, if desired. Or simply dust with powdered sugar or drizzle with maple syrup. Serve with vanilla sauce or a scoop of vanilla ice cream.
