1. Preheat oven to 350. Butter and flour a standard 9×5 loaf pan.
2. In a large bowl mix together the butter and sugar until fully combined. Add eggs and vanilla extract, mix well. Add mashed bananas, mix again until completely combined.
3. In a large measuring cup whisk flour, soda, nutmeg and cinnamon.

4. Working slowly, stir the flour mixture into egg mixture. Keep stirring until all flour is fully incorporated. The batter may still be a little lumpy from the bananas, this is normal. Pour batter into prepared loaf pan.

5. To make the streusel: pulse the butter, cinnamon, pecans and brown sugar a few times in a mini-chopper. Or, finely chop the pecans and mix them with the melted butter, cinnamon and brown sugar in a bowl. Press the mixture lightly onto the top of the banana bread.

6. Bake for 45 – 50 minutes or until top is golden and a cake tester comes out clean. Cool in the pan for 10 minutes. Then, carefully remove it from the pan and let it cool on a wire rack before serving.
