Preheat oven to 350F. Line a small loaf pan with parchment paper.
Whisk the flour and baking powder together.
Melt the butter.
Beat the eggs.
Mix all ingredients together and pour batter into lined loaf pan and bake for 1 hour. Check on it after 45 minutes with a butter knife. If the knife comes out clean, it's ready. If it comes out with some batter on it, check on it again in 10 minutes.
