Ingredients

  • 1 box Duncan Hines banana supreme cake mix
  • 2 eggs
  • 1 cup water
  • 1 1/2 to 2 bananas
  • 1 container (8 oz.) sour cream
  • 1 c. confectioners sugar
  • 1 tsp. lemon juice
  • 1 Tbsp. milk

Instructions

  1. Mix the cake mix, eggs, water, 1/2 container sour cream, and 1 1/2 mashed bananas using a mixer until lumps have dissolved.
  2. Pour the batter into two 9-inch round pans or one large oblong pan, lining the round pans with wax paper if desired.
  3. Bake as directed on the cake mix box.

Tips & Substitutions

For a richer flavor, consider adding a teaspoon of vanilla extract or a pinch of cinnamon to the batter. If you're short on bananas, you can use applesauce as a substitute, though it may alter the taste slightly. To enhance moisture, use full-fat sour cream instead of light. If you prefer a creamier frosting, mix the confectioners' sugar with additional sour cream.

Serving Suggestions

Serve this delicious banana cake with a dollop of whipped cream or a scoop of vanilla ice cream for an indulgent dessert. It pairs beautifully with Sean Johnson's Orange Julius for a refreshing contrast. Consider adding fresh fruit on top or a sprinkle of nuts for added texture. This cake is perfect for birthdays or casual gatherings.

Storage & Reheating

Store leftover banana cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate it for up to a week. If you want to enjoy the cake later, wrap individual slices in plastic wrap and freeze for up to 3 months. Thaw in the refrigerator overnight before serving.

Frequently Asked Questions

Can I make this cake without bananas?

While bananas are a key ingredient, you can substitute them with applesauce or even pureed pumpkin for a different flavor profile. Keep in mind that the cake's texture and taste will change, so adjust the sweetness accordingly.

How can I make this cake gluten-free?

To make a gluten-free version, use a gluten-free banana cake mix. Ensure that all other ingredients, including the sour cream and confectioners' sugar, are gluten-free. This will help maintain the moistness of the cake without compromising on flavor.

What can I use instead of sour cream?

If you don't have sour cream on hand, Greek yogurt works as a great substitute. It provides similar creaminess and tanginess. You can also use buttermilk or a dairy-free yogurt alternative for a lighter option.
