What is a Snack Cake?
If you have ever traveled through the snack aisle at the grocery store, you've probably noticed pre-packed snack cakes. A snack cake is slightly denser than a regular cake. It holds up to being held in your hand - and tastes just as sweet and delicious as homemade cake.
Banana Bread vs Banana Cake
Let's not get this banana snack cake recipe confused with banana bread. Not only is bread baked in a loaf pan, but it has an even denser texture than this cake.
This snack cake is dense enough to hold in your hand, but lighter and spongier than banana bread.
If you tried to bake this in a loaf pan, it will come out tasting more like a pound cake than banana bread.

Cake Baking Tips
- Always have all the ingredients at room temperature.
- Prepare the cake pan (greasing and flouring) before starting on the batter.
- Cream butter at medium speed so it is smooth and not fluffy.
- Sift powdered sugar to remove any lumps.
- When mixing in powdered sugar, start on low speed until it is incorporated and increase the speed to medium.
- Use quality cake pans that are light in color. Aluminum is best. Dark or black metal pans will cook the cake faster and you'll need to reduce the oven temperature by 25°F.
How to Store and Freeze
To Store: The cake should be stored in an airtight container or wrapped in plastic wrap. Unfrosted cake can be stored at room temperature. Frosted cake should be stored in the refrigerator. The banana cake will last up to 5 days.
To Freeze: The cake should be placed in a freezer-safe container, plastic freezer bag, or wrapped in plastic wrap and aluminum foil. Cake will last up to 3 months in the freezer.
To Thaw: Unfrosted cake can be thawed on the counter. Frosted cake should be thawed in the refrigerator overnight.
