Ingredients

2 cups all-purpose flour

1 1/2 teaspoons baking powder

1/2 teaspoon baking soda

1/2 teaspoon salt

1 teaspoon ground cinnamon (optional, but I love it)

1/2 cup (1 stick) unsalted butter, softened

1 cup granulated sugar

2 large eggs, room temperature

1 teaspoon vanilla extract

3/4 cup sour cream or plain Greek yogurt

2 cups mashed very ripe bananas (about 4 medium)

1/2 cup chopped walnuts or pecans (optional)

Cream Cheese Frosting:

8 ounces cream cheese, softened

1/4 cup unsalted butter, softened

2 cups powdered sugar, sifted

1 teaspoon vanilla extract

Pinch of salt

Splash of milk if needed to thin

Tools Needed

9×13-inch baking pan (a sheet cake size)

Mixing bowls (1 large for batter)

Electric mixer or sturdy whisk

Spatula

Measuring cups and spoons

Cooling rack

Fork or potato masher for bananas

Optional: paddle attachment for stand mixer

Suggested Substitutions and Additions

Flour: Substitute 1:1 gluten-free flour blend for a gluten-free version.

Sugar: Use 3/4 cup brown sugar for a deeper caramel note.

Butter: Replace half the butter with applesauce for a lighter cake (texture will change slightly).

Dairy: Use a vegan cream cheese and vegan butter to make the frosting dairy-free.

Extras: Fold in 1 cup chocolate chips or 1/2 cup shredded coconut for variety.

Spices: Add 1/4 teaspoon nutmeg or a pinch of cardamom for warmth.

How to Make Easy Banana Sheet Cake with Cream Cheese Frosting

Step 1: Prep and Preheat

Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan and line the bottom with parchment for easy removal.

Mash ripe bananas with a fork until mostly smooth; a few small lumps are okay — they give texture and personality.

Tip: Use bananas with lots of brown spots — they’re sweeter and more aromatic.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together:

2 cups flour

1 1/2 teaspoons baking powder

1/2 teaspoon baking soda

1/2 teaspoon salt

1 teaspoon cinnamon (optional)

Make sure there are no lumps of baking powder — a light, even mix will help rise uniformly.

Step 3: Cream Butter and Sugar

In a large bowl, using an electric mixer or a wooden spoon, cream 1/2 cup softened butter with 1 cup sugar until pale and fluffy (about 2–3 minutes).

You’ll smell a buttery sweetness lifting off the bowl — that’s the cozy scent of a cake coming together.

Step 4: Add Eggs, Vanilla, and Wet Ingredients

Beat in eggs one at a time, scraping the bowl after each addition.

Stir in 1 teaspoon vanilla extract.

Mix in 3/4 cup sour cream or Greek yogurt until smooth and slightly glossy.

Step 5: Combine Banana and Batter

Fold mashed bananas into the wet mixture gently.

Add the dry ingredients to the wet in two additions, folding until just incorporated — don’t overmix. A few streaks of flour are okay; they will disappear during baking.

Fold in 1/2 cup nuts or chocolate chips if using.

Step 6: Bake the Sheet Cake

Pour batter into the prepared 9×13 pan, smoothing the top with a spatula.

Bake at 350°F for 25–30 minutes or until a toothpick inserted into the center comes out with just a few moist crumbs. The edges will pull slightly from the pan and smell nutty and warm — you’ll know it’s ready.

Let the cake cool completely on a cooling rack before frosting — warm cake will melt the frosting and make it runny.

Step 7: Make the Cream Cheese Frosting

In a bowl, beat 8 ounces softened cream cheese with 1/4 cup softened butter until smooth and lump-free.

Add 2 cups powdered sugar gradually and 1 teaspoon vanilla, plus a pinch of salt.

If the frosting is too thick, add a teaspoon of milk at a time until it’s spreadable but still holds shape.

Step 8: Frost and Finish

Once the cake is completely cool, spread the frosting evenly.

If you want, sprinkle chopped nuts or a dusting of cinnamon on top.

Chill for 20–30 minutes to set the frosting before slicing into squares.

What to Serve with Easy Banana Sheet Cake with Cream Cheese Frosting

A dollop of whipped cream or a scoop of vanilla ice cream for an upscale dessert.

Fresh berries or a simple raspberry compote to cut through the richness.

Coffee, chai tea, or a chilled glass of milk are perfect beverage pairings.

For a Southern brunch vibe, serve beside a pot of good coffee and a fruit salad.

Tips for Making It Perfect

Prep in advance: Mash the bananas and store in a covered bowl in the fridge up to 24 hours. Bring to room temp before baking.

Fix common mistakes: If your cake comes out too dense, you probably overmixed or your baking powder is old. Fresh leavening and gentle folding are key.

Make ahead / double batch: The cake (unfrosted) freezes beautifully. Bake, cool, wrap tightly, and freeze up to 3 months. Thaw overnight in the fridge and frost the next day.

Frosting tip: If frosting is too sweet, add a tiny pinch of salt or a squeeze of lemon to balance.

Serving tip: For neat slices, chill the frosted cake 30 minutes, then use a sharp knife warmed with hot water (wiped clean between cuts).

Storage Instructions

Room temperature: Store covered for up to 2 days (in a cool climate).

Refrigerator: Store in an airtight container for 5 days.

Freezing:

Unfrosted cake: Wrap tightly in plastic and foil, freeze up to 3 months. Thaw overnight in the fridge.

Frosted cake: For best texture, freeze slices on a tray, then transfer to a container. Thaw in the fridge.

Reheating: Warm a slice in the microwave for 10–15 seconds for that freshly-baked feel (but avoid over-heating the cream cheese frosting).

General Information

Banana cakes have been a home-kitchen staple for decades because they elegantly turn overripe fruit into something celebratory. This sheet cake is descended from simple banana loafs and quick-bake traditions — think of church bake sales and family potlucks where everyone knows the baker by the slice they bring. My grandmother used to drop a spoonful of sour cream into her batter; it always made the crumb tender and slightly tangy. I kept that trick in here because it works — it’s a little secret for a softer crumb and better shelf life.

Frequently Asked Questions

Q1: Can I use overripe frozen bananas?

A1: Yes — thaw them, drain any excess liquid if watery, then mash. Frozen bananas are excellent for sweetness and texture.

Q2: How long will this cake keep in the fridge?

A2: About 5 days in an airtight container. The cream cheese frosting keeps it moist but also means refrigeration is best.

Q3: Why is my cake dense?

A3: Common causes are overmixing the batter, old leavening agents (baking powder/soda), or heavy substitutions. Gently fold ingredients and ensure your baking powder is fresh.

Q4: Can I make this cake gluten-free or vegan?

A4: Use a 1:1 gluten-free flour blend for gluten-free. For vegan, replace butter with vegan butter, eggs with flax eggs (1 tbsp ground flax + 3 tbsp water per egg), and use vegan cream cheese for the frosting — results will vary slightly.

Q5: How do I prevent the frosting from being runny?

A5: Make sure the cake is completely cool before frosting. Chill the frosting briefly if it’s too soft, and use full-fat cream cheese for stability.
