These eggless banana bars with cream cheese frosting are soft, fluffy, and packed with real banana flavor — made completely without eggs, no special replacer needed. Most banana bar recipes lean on eggs; this one was designed egg-free from the very start, so everyone at the table gets the same square. Very ripe bananas, yogurt, and a quick homemade buttermilk keep the crumb moist and tender, and one sheet pan turns it all into 24 shareable bars with zero fuss. If you’ve got spotty bananas on the counter and a crowd to feed, this is the one.
Oriana’s Thoughts On The Recipe
If you’ve got overripe bananas sitting on the counter and a crowd to feed, these eggless banana bars are about to become your shortcut. There’s no fuss here — make the batter, pour, spread, and bake. One pan turns those spotty bananas into 24 fluffy, flavor-packed squares everyone can grab — no slicing a loaf, no waiting your turn. I love banana bread as much as anyone, but a loaf only goes so far at a potluck or class party.
And because my youngest has had an egg allergy since she was one, this is egg-free by design — not a swapped-out version she has to settle for. That’s the whole point around here: no one left out at the table.
Why You’ll Want to Try My Recipe
Can You Make Banana Bars Without Eggs?
Yes — these banana bars are completely egg-free by design, with no egg replacer required. Very ripe mashed bananas add moisture and binding, plain yogurt keeps the crumb tender, and a quick buttermilk (milk stirred with a little vinegar) gives the bars lift. Together, they do everything eggs normally would, so the bars stay soft, hold together, and slice cleanly.
Ingredients You’ll Need, Substitutions & Notes
Scroll down to the recipe card for all the details, including measurements and instructions.
Most of these are pantry staples you already have — a few are worth a quick note.
- Ripe bananas: The spottier, the better. Very ripe bananas mash smooth, taste sweeter, and bring the moisture that stands in for eggs here — about 1½ cups mashed (3 bananas).
- Plain yogurt: One of the quiet workhorses in egg-free baking — it adds moisture and a tender structure. Use regular, not Greek, for the softest crumb.
- Milk + apple cider vinegar: Stirred together, they make a quick buttermilk that gives the bars lift and a gentle tang. Don’t skip the rest time — you want it slightly curdled.
- Brown sugar: Adds moisture and a soft caramel note alongside the granulated sugar.
- Cream cheese (full-fat block): For frosting that’s tangy and sturdy enough to cut clean. Skip the spreadable tub kind — it’s too soft to set up.
Food Allergy Notes & Swaps
This recipe does not contain eggs, tree nuts, peanuts, soy, sesame, fish, or shellfish as ingredients. Manufacturing lines change — read every label every single time, even brands you have used before. That habit has never steered me wrong.
Need Dairy-Free or Gluten-Free?
If you are navigating additional dietary needs alongside the egg-free requirement, I have detailed guides for both: How I Replace Dairy in My Egg-Free Recipes – Baking Without Eggs and Gluten
Ingredient Swap Suggestions
- Dairy-Free: To make this recipe dairy-free, you can easily swap out the dairy ingredients for non-dairy alternatives.
- Butter: Substitute butter with dairy-free butter substitutes. Miyoko’s Creamery Organic Vegan Butter, Trader Joe’s brand vegan butter, and Earth Balance Vegan Buttery Sticks are my favorite butter substitutes for baking. For the best flavor, use a vegan butter that tastes good. Use sticks or blocks, not tub (spreadable) butter.
- Milk: You can use your favorite non-dairy milk, like soy or oat milk.
- Yogurt: Use your favorite brand of plain, unsweetened non-dairy yogurt.
- Cream Cheese: To substitute the cream cheese, I like to use Violife Just Like Cream Cheese Original.
- Gluten-Free: Use a gluten-free, all-purpose flour blend. Look for a gluten-free flour blend specifically formulated for baking, as it will have the right combination of flours and starches to mimic the texture of wheat flour. My favorite is Better Batter Original Blend. I also like Doves Farm Freee Gluten-Free All-Purpose Flour, but this blend does not contain xanthan gum, so you need to add 1/4 teaspoon of xanthan gum per cup (140 g) of gluten-free flour blend.
What I Learned Testing This Recipe
After 13+ years of egg-free baking, I can tell you most recipes put up a fight before they’re right. This one didn’t — it came together so smoothly I almost didn’t trust it. Still, a few things made the difference between good and perfect.
- Don’t panic if it looks broken. When the mashed bananas hit the creamed butter and sugar, the mixture can look broken — almost curdled. It’s fine. The moment the flour and buttermilk go in, everything comes together into a smooth, thick batter.
- The batter taught me to stop mixing early. Once the flour goes in, a few lumps are exactly right — beating it smooth develops the gluten and turns the bars dense instead of tender.
- Spread the batter as evenly as you can before it goes in the oven. A half sheet pan is big, and if the batter sits thicker on one side, you’ll get uneven bars — take an extra few seconds with the spatula and level it corner to corner.
- Trust two doneness cues, not the clock: the bars are ready when a toothpick comes out clean, and the top feels springy when you press it gently with a finger.
- And here’s the make-ahead win — these stay soft and fluffy for several days, so you can absolutely bake them the day before your party.
- Pan size mattered more than I expected. The half sheet is the sweet spot for 1-inch bars that bake through evenly and still feed a crowd; a smaller pan makes them too thick in the middle.

- Whisk the Dry Ingredients
- Cream the Butter and Sugars
- Add Yogurt and Bananas
- Add the Flour and Buttermilk
- Pour and Spread
- Bake
- Make the Frosting
- Frost and Cut
Tips & Troubleshooting
- Use very ripe, heavily spotted bananas — they mash smoother and give the deepest flavor and most moisture.
- Spread the batter evenly — take an extra moment to level it corner to corner so the bars bake up the same thickness everywhere.
- Don’t overmix. Stop as soon as the dry streaks disappear; overmixing is the #1 cause of dense bars.
- Check for doneness at 30 minutes. They’re ready when a toothpick comes out clean and the top springs back when gently pressed.
- Problem: the frosting slides off. The cake was still warm. Cool it completely (a stint in the fridge speeds it up) before frosting.
- Problem: ragged squares. Wipe your knife clean between cuts for neat edges.
Making These Banana Bars for a Crowd (Make-Ahead & Transport)
These bars were built to be shared, so they’re easy to make ahead. Bake the cake a day early, cool it completely, cover, and refrigerate — then frost and cut the day you’re serving. Heading to a potluck or class party? Frost right in the pan, chill until the frosting sets, then cut and cover for travel. Because every bar is egg-free, it’s the one dessert you can bring knowing the egg-allergic kid in the room gets the exact same square as everyone else.
Storage and Freezing Instructions
Store the bars in an airtight container at room temperature for 1–2 days — they stay soft and fluffy. If your kitchen runs warm, keep them in the refrigerator instead because of the cream cheese frosting; just bring them to room temperature for a few minutes before serving for the softest texture. They’re also a great make-ahead treat — bake the day before, and they’ll still be soft and fluffy for the party.
You can also freeze the bars, frosting and all. Place the sliced bars on a parchment-lined baking sheet and put the entire sheet in the freezer. After 1–2 hours, when the bars and frosting are firm, wrap them in plastic wrap and store them in a zip-top freezer bag for up to a month.

Eggless Banana Bars With Cream Cheese Frosting
These eggless banana bars are soft, moist, and tender, baked in one half sheet pan and finished with a tangy cream cheese frosting — completely egg-free by design. Very ripe bananas, yogurt, and a quick buttermilk replace the eggs, so the bars stay moist and slice cleanly into 24 squares. Simple pantry ingredients, no special egg replacer, and easy enough for beginner bakers.
• For best results, I highly recommend using a kitchen scale to measure the ingredients.
For the Eggless Banana Bars:
For the Cream Cheese Frosting:
-
Prep your pan and oven: Preheat the oven to 350°F (180°C). Generously spray a half sheet pan (17.9 x 12.9 x 1 inches / 42 x 29.5 cm) with nonstick cooking spray and set aside.
-
Whisk the dry ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and cinnamon until evenly combined. Set aside.
-
Make the buttermilk: In a small bowl, stir together the milk and vinegar. Let it stand at room temperature for 5 minutes — it’s ready when the milk looks slightly thickened with small curdled bits. Set aside.
-
Mash the bananas: Mash the bananas with a fork until mostly smooth with just a few small lumps — about 1½ cups.
-
Cream the butter and sugars: In a large bowl, beat the butter, granulated sugar, brown sugar, and salt on medium-high speed until creamy and fluffy, about 3 minutes, scraping down the bowl as needed. Add the mashed bananas, vanilla, and yogurt, and beat until combined.Note: The mixture might look broken or curdled at this point — don’t worry, once you add the flour and milk mixture, everything comes together nicely.
-
Add the flour and buttermilk: Reduce the speed to low and add half the flour mixture, scraping and folding so everything incorporates. Pour in the buttermilk mixture and beat to combine, then add the remaining flour and beat just until no dry streaks remain. The batter will be slightly thick with a few lumps — do not overmix.
-
Pour and spread: Scrape the batter into the prepared pan and spread evenly.
-
Bake: Bake for 30–35 minutes, until golden, and a toothpick comes out clean (a few moist crumbs are fine, no wet batter). Start checking at 30 minutes.
-
Cool completely: Set the pan on a wire rack and cool completely before frosting — a warm cake melts the frosting.
-
Make the frosting: Beat the cream cheese and butter on high until smooth, about 3 minutes. Add the salt and vanilla. Reduce to low, add the confectioners’ sugar, beat 30 seconds, then high for 3 minutes until fluffy. Add the extra ¼ cup of sugar for a thicker frosting.
-
Frost and cut: Spread the frosting over the fully cooled cake. Cut into 24 bars (a 6 x 4 grid), wiping your knife clean between cuts.
Store the bars in an airtight container at room temperature for 1–2 days — they stay soft and fluffy. If your kitchen runs warm, keep them in the refrigerator instead because of the cream cheese frosting; just bring them to room temperature for a few minutes before serving for the softest texture. They’re also a great make-ahead treat — bake the day before, and they’ll still be soft and fluffy for the party.
Freeze: You can also freeze the bars, frosting, and all. Place the sliced bars on a parchment-lined baking sheet and put the entire sheet in the freezer. After 1–2 hours, when the bars and frosting are firm, wrap them in plastic wrap and store them in a zip-top freezer bag for up to a month.
