Notes for making Banana Crumb Cake

Banana Crumb Cake

  • Whenever you have bananas going brown, place in a plastic baggie and mash.  Write on the baggie how many bananas are in each bag.  If you want to simplify baking Banana Crumb Cake – add three to a bag! When you are ready to bake, thaw before using.
  • For an even more indulgent cake, top your banana crumb cake with a simple vanilla glaze. Make by combining 1 cup of powdered sugar with 12 tablespoons of milk and 1 teaspoon of vanilla extract and drizzling it over the cooled cake.
  • Adding spices create a further dimension and depth of flavor: add 1 teaspoon of ground cinnamon and/or 1/2 teaspoon of ground nutmeg to the streusel topping. 
  • For an extra moist cake, use buttermilk instead of whole milk.
  • To make your own self-rising flour, simply add 1 1/2 tsp baking powder and 1/2 tsp salt for EACH cup of all-purpose flour.
  • To soften cold butter, microwave one cube of butter in wrapper for approx 1 minute 30 seconds at 20% power. You may need more or less time depending on your microwave. It can take up to 4 minutes to soften. Be careful not to melt the butter!  Microwaving at such low power gives you the best control.
