Easy Banana Bars with Cream Cheese Frosting Recipe

I turn ripe bananas into these soft, tender banana bars when I want an easy dessert that feels homemade and crowd-friendly. The cream cheese frosting gives me a rich, tangy finish that pairs especially well with the naturally sweet banana flavor.

I like this recipe because I can use very ripe bananas that might otherwise be overlooked. The bars bake in a shallow pan, cool quickly, and give me plenty of pieces to share at a gathering, family dessert table, or casual afternoon treat.

Why I Love These Banana Bars

I enjoy the contrast between the moist banana bars and the smooth cream cheese frosting. I also find them easier to prepare than a layer cake because I can bake everything in one jelly-roll pan and frost the cooled bars right in the pan.

When I have extra-ripe bananas available, this is one of the desserts I like to keep in mind. I get a tender crumb, plenty of banana flavor, and a creamy topping without a complicated decorating process.

Ingredients for My Banana Bars

I bring the butter and eggs to the recommended temperature before I start so the batter comes together smoothly. I also mash the bananas ahead of time, which makes it easier to fold them into the finished batter without overmixing.

How I Make the Banana Bars

Step 1: Make the batter

Preheat the oven to 350°F. In a large bowl, use a hand mixer or stand mixer to cream the butter and sugar together until light and fluffy, five to seven minutes. Add the eggs, sour cream and vanilla extract.

In a separate bowl, whisk together the all-purpose flour, baking soda and salt. Gradually add the flour mixture to the creamed mixture just until combined.

Step 2: Add the bananas

Stir in the mashed bananas just until combined. I make sure the bananas are pre-mashed before adding them because that helps me avoid overworking the batter while trying to break up larger pieces.

Step 3: Bake the banana bars

Spread the batter into a greased 15x10x1-inch baking pan, also known as a jelly-roll pan. Pop the pan into the oven and bake the banana bars until a toothpick inserted in the center comes out clean, 20 to 25 minutes. I avoid overbaking because the bars can become very dry.

I let the banana bars cool completely to room temperature before adding the frosting.

Step 4: Whip up the cream cheese frosting

In a large bowl, use a hand mixer or stand mixer to beat the cream cheese, softened butter and vanilla extract until fluffy. Gradually beat in enough of the confectioners’ sugar to reach the desired consistency.

My tip: If my confectioners’ sugar is clumpy, I sift it first so the frosting stays smooth instead of lumpy.

Step 5: Frost and serve

I spread the frosting evenly over the room-temperature banana bars. I can add simple swoops or another easy decorating pattern before slicing and serving. I refrigerate any leftovers because the bars are topped with cream cheese frosting.

Banana Bar Variations I Like

• Berry or nut mix-ins: I can fold in berries, toasted nuts, or chocolate chips when I want extra texture and flavor.
• More banana flavor: I can add a little banana extract when I want the banana character to stand out even more.
• Chocolate frosting: I can switch to chocolate frosting for a dessert that reminds me of chocolate-covered bananas.
• Banana chip topping: I prefer dehydrated banana chips for decoration because fresh banana slices can brown quickly.
• Salted caramel: I like a light drizzle of salted caramel sauce or dulce de leche when I want a richer finish.

How I Store Banana Bars with Cream Cheese Frosting

I store frosted banana bars in the refrigerator for up to four days. When I keep them in the original pan, I cover them well with storage wrap. I can also place individual slices in an airtight container to make better use of refrigerator space.

Can I Freeze Banana Bars?

Yes. I can freeze the bars with or without the frosting. For frosted bars, I keep them in the pan or transfer individual slices to an airtight container and freeze for up to two months. I thaw them in the refrigerator overnight.

For unfrosted bars, I let them cool to room temperature, wrap them well with a few layers of storage wrap, and freeze them for up to two months. I thaw them at room temperature for about an hour before serving.

My Best Banana Bar Tips

• I use ripe bananas for stronger natural banana flavor.
• I bring the butter and eggs to the temperatures called for in the recipe before mixing.
• I mash the bananas before adding them to the batter.
• I watch the baking time closely so I do not overbake the bars.
• I cool the bars completely before spreading on the cream cheese frosting.
• I sift confectioners’ sugar when it looks clumpy so my frosting stays smooth.

How Can I Ripen Bananas Quickly?

When I need ripe bananas sooner, I can use a brown paper bag overnight or the oven method. For the paper-bag method, I place the bananas with another room-temperature fruit, such as an apple or orange, in a tightly closed brown paper bag and leave it overnight.

For a quicker oven method, I preheat the oven to 250°F and place unpeeled bananas on a baking sheet. I roast them until the skins turn black and the insides become soft, about 15 to 20 minutes, then let them cool before using them.

Can I Use Previously Frozen Bananas?

Yes. I let previously frozen bananas thaw completely to room temperature before I mash and use them in the recipe.

Can I Use a Different-Sized Pan?

Yes. I can use a 13×9-inch pan or two 9-inch round pans instead of the jelly-roll pan. The bars will be thicker, so I expect the baking time to change. I can also use muffin tins, although the result will be more like individual cupcakes.

How do I keep banana bars moist?

I avoid overbaking and let the bars come out when a toothpick inserted in the center comes out clean. I also cool them completely before frosting and store the finished bars properly.

Why did my cream cheese frosting turn lumpy?

I make sure the cream cheese and butter are softened before beating them. If my confectioners’ sugar has visible clumps, I sift it before gradually adding it to the frosting.
