• Preheat the oven to 350 degrees F. Lightly grease a 9x5 loaf pan with butter or line with parchment paper.
• Combine the einkorn flour, salt and baking soda well in a small bowl.
• Beat together the softened butter and brown sugar together for several minutes. You will see the butter and sugar mixture get light and fluffy and lighten in colour.
• Beat in room temperature eggs one at a time and then stir in mashed banana and vanilla.
• Pour into a greased pan and top with  the streusel topping mixture. 
• Bake for 60-65 minutes or until a toothpick inserted comes out clean. I recommend checking the banana bread for 50 minutes to avoid over-baking. In my oven this recipe takes upwards of an hour but every oven is different. Allow to cool in the pan for at least 1 hour before cutting into the loaf.

Instructions for Streusel topping:

• In a small bowl combine flour, brown sugar, oats, cinnamon and salt and whisk together. Add softened butter and mash the ingredients with a fork until the butter is mostly incorporated.
• Crumble the streusel topping over the top of your banana bread batter once it’s in the pan. Don’t overload the centre of the loaf because you don’t want to prevent the loaf from rising evenly.
