Buttery, banana-forward, and so tender that my fork did zero work ★★★★★

Ingredients You Need

  • 1.5 cups mashed very ripe bananas, about 3 medium with lots of brown speckles
  • 2 cups all-purpose flour, spooned and leveled; King Arthur or Gold Medal both measure consistently
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon fine sea salt
  • 1/2 cup unsalted butter, softened; use European-style butter like Kerrygold for extra richness, or use salted butter and reduce salt to a pinch
  • 1/2 cup granulated sugar
  • 1/2 cup light brown sugar, packed; swap all brown sugar for deeper caramel notes
  • 2 large eggs, room temp
  • 1/2 cup sour cream or full-fat Greek yogurt
  • 1 teaspoon pure vanilla extract
  • Optional flavor boosts: 1/2 teaspoon cinnamon, or 1/8 teaspoon nutmeg
  • Optional mix-ins: 1/2 cup chopped walnuts or pecans, or 1/2 cup mini chocolate chips

Optional simple glaze

  • 3/4 cup powdered sugar
  • 1 to 2 tablespoons milk
  • Pinch of salt
  • 1/4 teaspoon vanilla

Equipment

  • 8-inch square pan or 9-inch round pan
  • Parchment paper
  • Two mixing bowls, whisk, rubber spatula
  • Hand mixer or stand mixer, or whisk and strong wrist
  • Measuring cups and spoons, cooling rack

Pantry shortcuts and swaps

  • No sour cream on hand? Use plain full-fat yogurt.
  • Light on bananas? Add 2 tablespoons milk to reach a similar batter consistency.
  • Dairy-free path: use plant butter and coconut yogurt, and grease the pan with oil spray.

How to Make Easy Banana Butter Cake Recipe

Step 1: Prep the pan and heat the oven

  • Heat the oven to 350°F. Grease the pan and line it with a parchment sling so you can lift the cake out easily.
  • Peel and mash the bananas until mostly smooth. Leave a few small bits if you like a little texture.

Step 2: Mix the dry ingredients

  • In a small bowl, whisk flour, baking powder, baking soda, salt, and any spices. Set the bowl aside so it waits its turn.

Step 3: Cream the butter and sugars

  • In a large bowl, beat softened butter with granulated sugar and brown sugar for 2 to 3 minutes until the mixture looks pale and fluffy.
  • Beat in eggs one at a time until the batter looks smooth again.
  • Mix in vanilla, sour cream, and mashed bananas until combined. The batter may look slightly curdled at this point and that still bakes up tender.

Step 4: Add the dry ingredients

  • Add the dry mixture to the wet bowl in two additions. Mix on low just until you see no dry streaks.
  • Fold in nuts or chocolate chips if you want them. Smooth the batter into the prepared pan.

Step 5: Bake and cool

  • Bake 35 to 40 minutes, until the top springs back and a toothpick comes out with a few moist crumbs.
  • Let the cake cool in the pan for 10 minutes. Lift it out to a rack and cool until just warm or fully cool.

Step 6: Optional glaze

  • Stir powdered sugar, 1 tablespoon milk, salt, and vanilla until smooth. Add more milk, a few drops at a time, for a pourable glaze.
  • Drizzle over the cooled cake. Slice and serve.

Tips & Common Mistakes

  • Use very ripe bananas with lots of brown spots; green fruit gives bland flavor and a dry crumb.
  • Measure flour by weight or spoon and level to avoid dense cake.
  • Keep ingredients at room temp so the batter mixes evenly.
  • Mix gently after adding flour; overmixing builds gluten and toughens the crumb.
  • If the batter looks curdled after eggs, beat in 1 tablespoon flour, then continue.
  • Check doneness at 32 minutes and every 3 minutes after; ovens vary.
  • Tent the cake with foil if the top browns too fast.
  • Cool at least 10 minutes before lifting from the pan to avoid breaks.
  • Use a metal pan for even browning; glass can run hot, so start checking earlier.
  • Add nuts only if you enjoy crunch; they can mask the soft butter texture.

Variations I've Tried

  • Brown butter version: brown the butter, cool to room temp, then beat with sugars.
  • Cinnamon-sugar swirl: mix 2 tablespoons brown sugar with 1 teaspoon cinnamon and ripple it through the batter.
  • Chocolate chip: fold in 1/2 cup mini chips.
  • Nutty crunch: add 1/2 cup toasted walnuts or pecans.
  • Cream cheese frosting: beat 4 ounces cream cheese, 2 tablespoons butter, 1 cup powdered sugar, and 1/2 teaspoon vanilla.
  • Gluten-free: swap in a quality 1:1 baking blend and add 1 tablespoon milk if the batter feels thick.
  • Loaf version: bake in a 9 by 5 loaf pan for 50 to 60 minutes.
  • Bundt mini cakes: divide into greased mini Bundt wells and bake 16 to 20 minutes.

How to Serve

Cut generous squares and serve slightly warm so the butter aroma greets everyone at the table. Dust with powdered sugar, drizzle the quick glaze, or add a spoon of vanilla ice cream for a weekend treat. I like it with coffee in the morning and with black tea in the afternoon because balance. Fresh berries add color and a bright note that plays well with the sweet banana crumb.

Make-Ahead and Storage

  • Room temp: Store covered at room temp up to 2 days.
  • Fridge: Wrap tightly and chill up to 5 days. Bring slices to room temp or warm briefly before serving.
  • Freezer: Wrap slices in plastic, then place in a freezer bag for up to 2 months. Thaw on the counter for 45 to 60 minutes.
  • Reheat: Warm a slice in the microwave for 10 to 15 seconds or in a 300°F oven for 8 to 10 minutes until the crumb softens again.
