Preheat oven to 350F and butter your pan. I like to line with a sling of parchment paper so I can remove the cake for frosting and serving, but that's optional.
Cream the butter, sugar and sour cream together. Beat in the egg, bananas, vanilla, and poppy seeds. (Make sure the bananas are mashed smooth first)
Sift your flour, baking soda and salt into the wet mixture and blend just until thoroughly combined ~ but don't over mix.
Spread the batter into your prepared baking pan.
Bake for about 25 minutes until a toothpick just comes out clean.*
Let the cake cool before frosting.
To make the frosting--- blend everything together until you have a thick, creamy, spreadable consistency. Taste to adjust your lemon juice. Note: I do this quick and easy in my food processor. This way you can start with cold cream cheese!
Heap onto the completely cooled banana cake and swirl it around thickly.
Notes
*Baking time is only a suggestion. Ovens bake differently and your time may vary from mine.
