I don't know if you're anything like me, but I love to bake at any time.  Being home for going on 7 weeks now (!!!), I have been craving this more than anything, which is part of the reason that I discovered this incredible banana crumb cake recipe.  My mom and I made it first together, following this recipe, which turned out incredible.  The next time I made it, I adjusted some things, and also thought about ways that it could be adapted for different diets.  If you don't eat eggs or dairy, a simple substitution could be plain non-dairy yogurt in place of the sour cream, applesauce instead of eggs, and a non-dairy butter. 

This banana crumb cake recipe is simple enough that I think anyone could make it, but yields incredible results.  This can last up to 3 days at room temperature or 3 months frozen. (as if it will go uneaten for that long...)

    Combine softened butter and sugar with mixer or by hand in a bowl or until well combined. Add mashed bananas, eggs, vanilla and sour cream.

  • Step 3

    Add dry ingredients and stir until just combined, being careful not to overmix. I would highly recommend combining dry ingredients SLOWLY, so this does not happen to you. Lumps are okay! Pour into greased pan and set aside while you prepare the topping.

  • Step 4

    Combine all topping ingredients in another small bowl. I find it easiest to use my fingertips to break up the butter and combine everything to get a fine mixture. You want there to still be crumbles of butter and sugar, so make sure it is not a paste. Pour the topping over the batter in an even layer.

    Bake for 35-40 minutes, or until a toothpick comes out clean when inserted. Serve warm, or cool and cover.
