Instructions
- Set oven to 350F Lightly spray a 9x9 square baking pan. I like to line it with parchment paper so I can lift the cake out after baking for easy frosting and cutting.
- Cream the butter, sugar, and sour cream together until light and fluffy. Beat in the egg, mashed banana, poppy seeds, and vanilla.
- Whisk the flour, salt, and baking soda together and add to the wet ingredients. Mix until just blended.
- Turn the batter out into the pan and smooth out evenly. Bake for about 35 minutes, or until the top is just turning golden and the middle is set. A toothpick inserted in the center should be free of wet batter.
- Let cool on a rack completely before frosting.
- Make the frosting by beating the butter and sugar together with the lemon juice and food coloring, if using. Add a touch more juice if the frosting is too thick, or a little more sugar if too thin.
- I like to store the cake in the refrigerator, and it will keep for up to a week.
Notes
- Add the zest of the lemon to the frosting if you like for even more lemony flavor.
- Substitute chopped walnuts or pecans for the poppy seeds.
- Substitute cream cheese for the butter in the frosting.
