Ingredients
To get started on these luscious bars, gather up these pantry staples. Note: The full ingredients with measurements will be right under the article in the recipe card!
- Ripe Bananas: The star of the show! Make sure they are nice and spotty for the best natural sweetness and moisture.
- Unsalted Butter: Melted butter gives these bars a rich, silky crumb that oil just can’t match.
- Brown & White Sugar: We use a blend to get that perfect molasses-like depth and a lovely glossy finish.
- Egg: This acts as the binder to give our bars a bit of structure while keeping them fudgy.
- Vanilla Extract: Think of this as the “salt” of the dessert world; it enhances all those beautiful banana flavors.
- All-Purpose Flour: The base that holds all the goodness together.
- Baking Powder & Baking Soda: This duo ensures the bars aren’t too heavy, giving them just the right amount of lift.
- Salt: A pinch is essential to balance the sweetness of the sugars and bananas.
- Ground Cinnamon: This adds a warm, cozy spice that makes your whole kitchen smell like a dream.
- Chocolate Chips: Because everything is better with pockets of melty chocolate, right?
- Walnuts: Optional, but they add a fantastic crunch that contrasts beautifully with the gooey texture.
How to Make the Recipe

Step 1: Prep and Pan
First things first, get your oven preheating to 350°F. Line an 8×8-inch baking pan with parchment paper, leaving a little overhang on the sides so you can easily lift the bars out later.
Step 2: Mix the Wet Ingredients
In a nice big bowl, whisk together your melted butter and both sugars. Keep going until the mixture looks smooth and glossy. Stir in those mashed bananas, the egg, and your vanilla until it’s all one big happy mixture.
Step 3: Combine Dry Ingredients
In a separate smaller bowl, give your flour, baking powder, baking soda, salt, and cinnamon a quick whisk to get rid of any lumps.
Step 4: Fold it All Together
Slowly fold the dry ingredients into the wet banana mixture. The key here is to be gentle! Mix until just combined—overmixing can make the bars tough, and we want them ultra-soft.
Step 5: The Fun Part
Gently fold in your chocolate chips and those crunchy walnuts if you’re using them. Spread the batter evenly into your prepared pan.
Step 6: Bake to Perfection
Pop them in the oven for 30-35 minutes. You’re looking for the edges to be set and golden, but the center should still look a little soft—that’s where the “ooey gooey” magic happens!
Step 7: Cool and Enjoy
I know it’s hard, but let them cool for at least 20 minutes. This helps the texture set so you get those perfect, fudgy slices.
Pro Tips for Making the Recipe
- Don’t Overbake!: This is the most important tip. If you leave them in too long, they’ll lose that signature gooey center. A toothpick should come out with a few moist crumbs.
- The Brown Sugar Trick: Use dark brown sugar if you want an even deeper, more caramel-like flavor.
- Mash Well: For the smoothest texture, mash your bananas until they are almost liquid. If you like little chunks of fruit, leave a few small pieces!
How to Serve

These bars are versatile enough for any time of day!
- Warm with Ice Cream: Serve a warm bar with a scoop of vanilla bean ice cream for a truly decadent dessert.
- Coffee Break: These are the perfect companion to a hot cup of coffee or a cold glass of milk.
- Drizzle it Up: Feel free to drizzle a little salted caramel sauce or extra melted chocolate over the top before serving.
Make Ahead and Storage
Storing Leftovers
Keep your bars in an airtight container at room temperature for up to 3 days. If you like them extra fudgy, you can keep them in the fridge!
Freezing
These bars freeze beautifully. Wrap individual squares in plastic wrap and store them in a freezer-safe bag for up to 3 months.
Reheating
To get that “just out of the oven” feel, pop a bar in the microwave for 10-15 seconds. The chocolate chips will get all melty again!
FAQs
1. Can I make these gluten-free? Absolutely! You can swap the all-purpose flour for a 1:1 gluten-free baking flour blend. Just make sure it contains xanthan gum for the best results.
2. My bananas aren’t ripe enough; what can I do? If you’re in a hurry, you can ripen them in the oven! Put unpeeled bananas on a baking sheet at 300°F for about 15-20 minutes until the skins turn black. Let them cool, and they’ll be perfect for mashing.
3. Can I use different mix-ins? For sure! Instead of walnuts, try pecans or macadamia nuts. You could even swap chocolate chips for white chocolate or butterscotch chips for a different flavor profile.
4. Why are my bars more like cake than “gooey”? This usually happens if the flour was packed too tightly in the measuring cup or if they were baked a few minutes too long. Try measuring your flour by spooning it into the cup and leveling it off next time!
