Preheat the oven to 400 degrees F and grease a 3qt baking dish with non-stick spray or butter.
Add the eggs to a large bowl and whisk well. Add the heavy cream, baking powder, erythritol, salt, and pepper. Mix well.
Next, add the melted butter, diced baby corn, and the squash. Gently stir until well combined.
Transfer this mixture to a baking dish and bake for 30 minutes, remove from the oven and stir then return to oven for an additional 30 minutes, or until the eggs are set lightly and the top is slightly browned.
