Ingredients for banana bread crumbl cookie
Twelve ingredients for a dessert that feels like a gourmet secret—soft banana bread meets crispy chocolate crumble in one perfect bite.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 cups | Mashed, about 2 medium bananas |
| All-Purpose Flour 🌾 | 2 cups | Spooned and leveled |
| Granulated Sugar 🍚 | 1 cup | Light brown preferred |
| Packed Brown Sugar 🍚 | ½ cup | For cookie crumble |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crumble |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Pure Vanilla Extract 🌿 | 1 tbsp | High-quality preferred |
| Baking Soda 🧂 | ½ tsp | Not baking powder |
| Ground Cinnamon 🌶️ | 1 tsp | Freshly ground |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Semisweet Chocolate Chunks 🍫 | ½ cup | High-quality for melting |
| Old-Fashioned Rolled Oats 🥣 | ½ cup | Blended into flour |
| Toasted Chopped Walnuts 🌰 | ¼ cup | Optional for crunch |
The bananas need to be ripe with brown spots—that’s when they’re sweetest. Trader Joe’s often has the perfect ones, or check the back of the produce section at Whole Foods where they keep the overripe ones. For the chocolate chunks, Ghirardelli or Valrhona melt beautifully, but any high-quality brand works. The oats? Old-fashioned rolled gives the best texture—quick oats get mushy. Toast the walnuts in a dry pan for 3-4 minutes until fragrant, then chop them roughly for that perfect crunch.
No vanilla extract? Vanilla bean paste works too, or even a pinch of vanilla sugar if you're in a pinch. The butter for the crumble needs to stay cold—cut it into small cubes and keep it in the freezer while you mix. Substituting brown sugar? White sugar plus 1 tsp molasses gets you close. Running low on chocolate chunks? Chop a bar of chocolate into small pieces—just make sure it’s at least 60% cacao for that rich flavor. The oats can be swapped for crushed graham crackers if you’re feeling fancy, but I’d recommend sticking with the oats for that classic crumble texture.
Store these in an airtight container at room temperature for 3-4 days—they’re best fresh, but the crumble stays crispy longer than you’d think. For longer storage, wrap individual cookies in plastic wrap and freeze for up to 3 months. I like to portion them into single servings straight from the pan so they’re ready to grab and go. The secret to keeping them moist? Don’t overbake—pull them out when the edges are just golden, not browned.

Step-by-step instructions for banana bread crumbl cookies
Here's how to create these triple-layered cookies with a moist banana bread center, crunchy oat crumble, and pockets of melted chocolate.
👨🍳 Step 1: Prepare the Banana Bread Dough
In a large mixing bowl, combine the 2 cups mashed ripe bananas with the 1 cup granulated sugar and 1 tbsp pure vanilla extract. Mix until smooth and creamy—this is your flavor foundation. In a separate bowl, whisk together the 2 cups all-purpose flour, 0.5 tsp baking soda, 1 tsp ground cinnamon, and 0.5 tsp salt.
Gradually add the dry ingredients to the banana mixture, mixing just until combined. Fold in the 0.5 cup semisweet chocolate chunks and 0.25 cup toasted chopped walnuts (if using) until evenly distributed. The dough will be thick but workable—don't overmix or you'll develop gluten and lose that tender texture.
👨🍳 Step 2: Create the Crumbl Topping
In a food processor, pulse the 0.5 cup old-fashioned rolled oats until they resemble coarse meal. Transfer to a medium bowl and mix with the 0.5 cup packed brown sugar and 1 cup cold cubed unsalted butter. Use your fingers to work the butter into the oat mixture until it resembles coarse crumbs with some pea-sized butter pieces remaining—this creates pockets of flavor when baked.
Press half of the crumbl mixture into the bottom of a 9-inch round cake pan (or similar size), creating an even layer. Drop spoonfuls of the banana bread dough directly onto the crumbl layer, spacing them about 1 inch apart. The dough should be slightly mounded—it will spread slightly during baking.
🔥 Step 3: Bake the First Layer
Preheat your oven to 350°F and bake the first layer for 12-15 minutes until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). This first bake sets the base while keeping the center tender—overbaking will dry it out.
Remove from the oven and let cool for 5 minutes before carefully spreading the remaining crumbl mixture evenly over the top. Drop the remaining banana bread dough spoonfuls onto this second crumbl layer, again spacing them about 1 inch apart. The visual contrast between the golden crumble and dark chocolate pockets is what makes these cookies irresistible.
🔥 Step 4: Finish Baking for Triple-Layered Perfection
Return to the oven and bake for an additional 12-15 minutes until the top layer is golden brown and the edges are crisp. The cookies should rise slightly and develop a caramelized aroma—this is your signal they're nearly done. Watch closely after 10 minutes to prevent overbrowning.
Let the cookies cool in the pan for 10 minutes before transferring to a wire rack. The contrast between the warm, gooey banana bread center, the crispy oat crumble, and the melted chocolate chunks is what makes these cookies extraordinary. Serve warm for the ultimate experience—each bite delivers three distinct textures in perfect harmony.
Pro Tips For Making Banana Bread Crumbl Cookie
- Mash Bananas Thoroughly: I learned this the hard way—lumpy banana puree makes for dry, uneven crumbles. Use a fork first to break up the flesh, then press through a fine-mesh sieve or mash against the side of the bowl until it’s completely smooth. No blender? A potato masher works, but elbow grease is key here.
- Brown the Butter First: Skip this, and your cookies lose that deep, nutty richness. Melt the butter over medium heat until it turns golden and smells toasty—about 5 minutes. Let it cool slightly before mixing, or the residual heat will cook the flour prematurely. (Yes, it’s worth the extra 10 minutes.)
- Don’t Overmix the Dough: Once you fold in the banana mixture, stir just until combined—overmixing develops gluten, and your crumbles turn dense instead of tender. Think "quick and gentle," like folding in a delicate sauce. The dough should look shaggy, not smooth.
- Chill the Dough 30 Minutes: Sounds weird, but it works: refrigerating the dough before baking prevents the cookies from spreading too much. Plus, the butter firms up slightly, giving you cleaner edges and a better crumble texture. (Pro move: use this time to preheat your oven to 350°F—no waiting!)
Wine and beer pairings for this dish
Sweet Wine Pairings
These banana bread crumbl cookies deserve a wine that complements their warm spices and rich chocolate notes.
A Moscato d'Asti from Italy is my go-to choice—its light sweetness and floral aroma enhance the banana's natural sweetness without overpowering the crunchy oat topping. 🍷 Serve chilled to let the fruity flavors shine alongside the caramelized edges.
For a slightly bolder option, try a Riesling with noticeable sweetness like a Dr. Loosen Blue Slate from Germany. The wine's honeyed notes mirror the banana's sweetness, while its acidity cuts through the richness of the chocolate chunks.
This pairing works especially well when the cookies are still warm from the oven.
Creamy Dessert Wines
If you prefer something heavier, a late-harvest Chenin Blanc from South Africa offers a perfect balance. Brands like Ken Forrester provide a luscious sweetness with a touch of citrus that refreshes your palate between bites. The wine's viscosity mirrors the cookies' texture, creating a delightful contrast.
Beer Pairing Options
A Belgian-style witbier like Hoegaarden or Stella Artois adds a crisp, citrusy contrast that cleanses your palate between bites. The light effervescence helps balance the cookies' richness, making each bite feel fresh.
For a darker option, try a honey brown ale with notes of caramel and toasted malt—Samuel Smith's Nut Brown Ale is a fantastic match.
Coffee or Tea Finish
For a non-alcoholic option, a strong brewed coffee with a splash of cream enhances the chocolate notes in the cookies. I recommend a dark roast like Starbucks Sumatra—its bold flavors complement the caramelized crumble. Alternatively, a chamomile tea with honey adds a soothing contrast to the cookies' warmth.
Seasonal Adaptations
In warmer months, pair these cookies with a sparkling rosé like Whispering Angel to highlight the fruity banana flavors. During colder seasons, opt for a spiced red wine such as Mulled Wine (warm with cinnamon and cloves) to echo the cookies' cinnamon and nutty undertones. 🌶️

Frequently asked questions
Can I make these banana bread crumbl cookies without nuts?
Simply omit the 0.25 cup toasted walnuts from the recipe. The texture and flavor will still be fantastic—just focus on the perfect balance between the soft banana bread and crispy oat crumble. For extra richness, you could even add 0.25 cup extra chocolate chunks to the crumble layer for a decadent twist.
How do I store leftover banana bread crumbl cookies?
Store them in an airtight container at room temperature for 3-4 days—they're best enjoyed fresh, but the crumble stays crispy longer than you'd expect. For longer storage, wrap individual cookies in plastic wrap and freeze for up to 3 months. The secret to keeping them moist? Don't overbake—pull them when the edges are just golden, not browned.
Why did my crumble layer turn out greasy instead of crispy?
This usually happens when the butter melts too much before baking. Keep the butter cold and cubed when mixing with oats, and work it in just until it resembles coarse crumbs with some pea-sized pieces remaining. The butter should create pockets of flavor that crisp up during baking—don't overmix or the texture will suffer.
Can I use quick oats instead of old-fashioned rolled oats?
Not ideal—they'll get mushy when baked. Old-fashioned rolled oats give that perfect crunchy texture we want. If you're out of rolled oats, you could try crushed graham crackers for a similar effect, but the flavor will be slightly different. For the best results, stick with the original recipe and toast your oats lightly before blending.
How do I prevent the banana bread layer from getting too dense?
Overmixing is the main culprit! Mix the dry ingredients into the banana mixture just until combined—stop when there are no more flour streaks. Also, make sure your bananas are ripe (with brown spots) for natural sweetness, and don't overbake. A toothpick should come out with moist crumbs, not wet batter. The first bake should be 12-15 minutes at 350°F—any longer and the texture suffers.
