Preheat the oven to 350°F. Line the bottom of a small Pyrex baking dish (see notes below) with parchment paper and grease the bottom and the sides with butter.
In a medium bowl, whisk the eggs with the stevia and melted butter.
Whisk in the almond flour, cornmeal, salt, and baking powder. If the batter is very thick and difficult to mix, add 1-2 tablespoons of water.
Transfer the batter to the prepared pan. Smooth the top out with a rubber spatula.
Bake until the bread is golden and set, and a toothpick inserted in the center comes out clean, 20-25 minutes.
Cool the bread for 10 minutes in the pan on a wire rack before slicing and serving.

Notes
Recommended pan:I use a rectangular 7 X 5–inch oven-safe glass food storage container because I like the bread to be tall. Using a standard square 8-inch pan is fine, but then the bread will not be as tall.You'll need to bake the bread for 20 minutes if using an 8-inch baking dish and for 25 minutes if using a smaller baking dish that produces taller bread.Approximate nutrition info if using a square baking dish and cutting the bread into 9 squares: Calories 228, Total Fat 20 g, Saturated Fat 6 g, Sodium 268 mg, Carbs 7.0 g, Fiber 3 g, Sugars 1 g, Protein 8 g. A reader recently emailed me that she successfully baked this bread in an 8-inch cast-iron skillet. So that's an option too.Recommended cornmeal:I typically use Bob's Red Mill coarse-grind cornmeal. I believe that with the very little I use here, a coarse grind has the biggest effect in terms of flavor and texture.Note that this cornmeal isn't marked by the company as gluten-free, while their medium-grind cornmeal is.Storage:Once completely cool, you can keep the leftovers in an airtight container in the fridge for up to 5 days. Warm them up in the microwave for 5 seconds per square. They also freeze well.
