Cream margarine and sugar until fully combined.
Add vanilla and eggs and mix. Mix in bananas.
Add the dry ingredients to the same bowl and mix. Mix in the creamer or milk.
Pour the batter into a 9×13 pan. Bake at 350 degrees Fahrenheit for 20 minutes.
Meanwhile, prepare the streusel crumbs. Combine with your hands until the texture resembles wet sand.
Remove the cake from the oven, top with the streusel, and then return to the oven for 20 to 30 minutes.
Combine the ingredients for the glaze. When the cake is cooled, drizzle glaze on top.
