Preheat the oven to 350 Fahrenheit. Grease a 9” baking dish or cast-iron skillet with avocado oil.
Combine flour, corn flour, baking powder and salt in a large mixing bowl.
Combine heavy cream, milk, maple syrup, eggs, avocado oil and melted butter in a second bowl. Mix until it is well combined.
Add the wet mixture to the dry and mix it gently with a spatula. Be careful not to over mix.
Pour it in your prepared baking dish and bake for 30 minutes, or until a toothpick comes out clean and dry. If you are using a cast iron skillet, the skillet will stay warm and continue to cook once out of the oven.
