Preheat the oven to 390 degrees F (400 degrees C). Coat a 9x5-inch loaf pan with Butter (1 tablespoon).
In a large bowl, use a hand mixer to mix the Egg (6), Almond Flour (1 1/2 cup), Butter (4 tablespoon), Baking Powder (3 teaspoon), and Salt (1 pinch) until combined.
Pour into the greased pan and bake for 25 minutes, or until a toothpick inserted in the center comes out clean.
Let cool for a few minutes, then slice and serve.
