Ingredients for 7brew banana bread blondie
Moist banana bread meets nutty blondie—just 15 ingredients for a coffee-infused dessert showstopper.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 large | Mashed for moist texture |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light batter |
| Granulated Sugar 🍚 | 1 ½ cups | White sugar preferred |
| Brown Sugar 🍚 | ½ cup | Packed for moisture |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Brewed Coffee Grounds ☕ | ½ cup | Cold, from 2 tbsp instant |
| Vanilla Extract 🌸 | 2 tsp | Pure vanilla preferred |
| Baking Soda 🧂 | 1 tsp | Freshly opened |
| Salt 🧂 | ½ tsp | Fine sea salt |
| All-Purpose Flour (Blondie Topping) 🌾 | 1 ½ cups | For nutty swirl |
| White Sugar (Blondie Topping) 🍚 | ¾ cup | Granulated sugar |
| Unsalted Butter (Blondie Topping) 🧈 | ½ cup | Melted, full-fat |
| Vanilla Extract (Blondie Topping) 🌸 | 1 tsp | Pure vanilla |
| Pecans 🌰 | 1 cup | Chopped, toasted |
The bananas are your secret weapon here. Ripe, spotted ones pack the most flavor and moisture—don't skimp. For the coffee grounds, instant coffee works best (just brew 2 tbsp with hot water, then cool completely). The butter needs to be room temperature—press it gently to make sure it's soft but not greasy. Kirkland Signature or Land O'Lakes are my go-tos for consistent quality. Pecans should be toasted in a dry pan for 3-4 minutes until fragrant—Trader Joe's sells pre-toasted ones if you're short on time.
No ripe bananas? Frozen works perfectly—thaw and drain excess liquid. Out of instant coffee? Strong brewed coffee cooled does the trick, but strain out any grounds. The blondie topping can be made with almonds instead of pecans if you prefer. For extra richness, add 1 tbsp of melted white chocolate chips to the blondie mix. If you're baking for a crowd, double the blondie topping—it's that good. The vanilla extract matters—imitation smells like perfume, so grab the real stuff from Williams Sonoma or Penzeys.
This keeps beautifully for 4-5 days in an airtight container at room temperature, though it's best enjoyed fresh. For longer storage, wrap tightly in plastic and refrigerate for up to 1 week. Slice before serving—the layers are delicate and should be cut with a serrated knife. If you make extras, freeze individual slices wrapped in parchment for up to 3 months. The coffee flavor actually deepens slightly after a day, so leftovers are even better.
Why You'll Love This Recipe

Step-by-step instructions for 7brew banana bread blondies
Here's how to create the perfect double-layered blondies with moist banana bread and nutty swirls.
Prepare the Banana Bread Base
Preheat your oven to 350°F and grease a 9x13-inch baking pan or line it with parchment paper. In a large mixing bowl, mash the 3 large ripe bananas until completely smooth—no lumps should remain. This step is crucial for that signature moist texture.
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 1.5 cups granulated sugar, 0.5 cup brown sugar, 1 tsp baking soda, 0.5 tsp salt, and 2 tsp vanilla extract. Gradually mix the dry ingredients into the mashed bananas until just combined. Avoid overmixing—you should still see small flour streaks.
Cut the 1 cup unsalted butter into small cubes and let it soften at room temperature for 10 minutes. Add the butter to the batter along with the 2 whole large eggs and the 0.5 cup brewed coffee grounds. Mix on low speed until the butter is fully incorporated and the batter is smooth and well combined. The coffee grounds add depth and help balance the sweetness.
Make the Blondie Topping
In a small bowl, combine the 1.5 cups all-purpose flour (blondie topping) and 0.75 cup white sugar (blondie topping). Cut in the 0.5 cup unsalted butter (blondie topping) using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Add the 1 tsp vanilla extract (blondie topping) and mix until evenly distributed.
Fold in the 1 cup chopped, toasted pecans to the topping mixture. Toasting the pecans first enhances their flavor—simply spread them on a baking sheet and bake at 350°F for 5-7 minutes until fragrant, then let cool before adding to the topping. The toasted pecans will add a delightful crunch and nutty flavor to each bite.
Assemble and Bake the Blondies
Spread half of the banana bread batter evenly into the prepared baking pan. Use a rubber spatula to create an even layer—this ensures both layers will bake uniformly. Sprinkle half of the blondie topping mixture over the batter, pressing down gently to create a swirl pattern. This step is key to achieving that beautiful marbled effect.
Add the remaining banana bread batter on top of the topping, spreading it evenly. Sprinkle the remaining blondie topping mixture over the top layer, again pressing down gently to create a swirl. The topping should be distributed evenly but not overly compacted—you want visible streaks of both batter and topping.
Bake in the preheated oven for 35-40 minutes or until a toothpick inserted into the center comes out clean. The blondies should be golden brown on top and slightly domed in the center. If the edges brown too quickly, tent the pan with aluminum foil to prevent over-browning. The internal temperature should reach 200°F for perfect doneness.
Cool and Serve
Allow the blondies to cool in the pan for 15-20 minutes before transferring them to a wire rack to cool completely. This cooling period is essential—it allows the layers to set and prevents the blondies from becoming gummy. Cut into 8 equal squares once fully cooled, using a sharp knife or a pizza cutter for clean slices.
Serve the blondies at room temperature for the best texture and flavor. Each bite should deliver a moist, banana bread base with pockets of nutty, buttery blondie topping. Store any leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week. The blondies will keep well, but they're best enjoyed fresh from the oven.
Pro Tips For Making 7brew Banana Bread Blondie
- Mash Bananas Properly: I learned this the hard way—skip the food processor for this recipe. Use a fork and really crush those ripe bananas until there’s barely any chunk left. The smoother the mix, the more even the texture in your blondies, and no one wants a surprise banana bite.
- Brown Butter First: Sounds weird, but it works: melt that unsalted butter until it’s golden and smells nutty, then let it cool slightly before mixing. The deeper flavor cuts through the sweetness, and the blondies won’t taste like sugar overload. Just don’t walk away—it burns faster than you think.
- Don’t Overmix the Batter: I used to beat this like I was trying to win a baking contest. Stop as soon as the flour disappears—overmixing makes blondies dense and tough. Stir just until combined, then fold in the coffee (if using) gently. Your future self will thank you for not turning these into cake bricks.
- Use Cold Coffee: If the recipe calls for brewed coffee, chill it first. Warm coffee makes the butter melt too fast, and suddenly your blondies spread like pancakes instead of holding their shape. Stick the coffee in the fridge for 10 minutes—it’s a small step that makes a real difference in texture.
Make-ahead tips for this dish
Prep Ahead Strategy
Start by making the banana bread batter and blondie topping the night before. Store both mixtures in airtight containers in the refrigerator for up to 24 hours.
This allows flavors to meld beautifully—the coffee infusion deepens overnight, and the pecans' aroma intensifies. Simply assemble and bake in the morning for a fresh-from-oven treat. 💫
Freezer-Friendly Layers
Assemble the blondies completely, then wrap the pan tightly in plastic wrap followed by aluminum foil. Freeze for up to 3 months. Thaw at room temperature for 1-2 hours before slicing. The texture remains moist, and the coffee notes become even more pronounced after thawing. Perfect for last-minute gatherings!
Portion Control Tips
For individual servings, bake the blondies in mini loaf pans (6x2-inch) instead of a sheet pan. Divide the batter and topping evenly among the pans, then bake for 20-25 minutes at 350°F. These single-serving portions reheat beautifully in the microwave for 10-15 seconds—ideal for quick pick-me-ups. 🍌
Make-Ahead Topping
Prepare the blondie topping up to 3 days in advance and store it in the fridge. The toasted pecans stay fresh longer when refrigerated. When ready to bake, simply mix the topping with the banana bread layer—no need to toast the pecans again. This shortcut saves time without sacrificing flavor.
Storage Hacks
Slice the blondies and store individual pieces in quart-sized freezer bags for easy grab-and-go portions. Label with the date—they're best enjoyed within 3 months of freezing. To reheat, microwave each slice for 15-20 seconds or warm in a 350°F oven for 5-7 minutes until lightly toasted.
Coffee Boost Tip
For an extra coffee kick, brew an additional 2 tbsp instant coffee and mix it into the blondie topping before assembling. This creates a subtle coffee flavor throughout both layers, enhancing the dessert's complexity. The aroma alone makes these blondies feel like a special treat. ☕
Nutrition facts
Frequently asked questions
Can I substitute regular coffee for instant coffee in this recipe?
Yes, but you'll need to strain it thoroughly to remove all grounds. Use ½ cup strong brewed coffee (cooled completely) instead of the instant version. The key is removing all liquid—just let it cool and strain through a fine-mesh sieve or cheesecloth. This keeps the texture perfect without gritty bits.
Why does my blondie topping look crumbly instead of smooth?
Overworking the topping mixture creates crumbs. Cut the 0.5 cup butter into the dry ingredients using your fingers or a pastry cutter until it resembles coarse crumbs—don't overmix. Cold butter is also the culprit—make sure it's softened but not melted. If it gets too crumbly, add 1 tsp cold milk to bind it together.
How do I make this recipe vegan?
Replace the eggs with 2 tbsp ground flaxseed mixed with 6 tbsp water (let sit for 5 minutes to thicken). Use vegan butter and ensure your vanilla extract is alcohol-free. For the coffee, use instant coffee that's certified vegan. The texture will be slightly denser but still delicious.
Can I use walnuts instead of pecans in the topping?
Walnuts work beautifully and add a different nutty depth. Toast them first for 3-4 minutes at 350°F1 tbsp maple syrup to the blondie topping mixture. The walnuts will give a slightly earthier flavor compared to pecans.
What if my banana bread layer is too dense?
Overmixing is usually the issue—stop mixing as soon as the dry ingredients disappear. For extra moisture, add 2 tbsp Greek yogurt or 1 tbsp melted butter to the batter. Also ensure your bananas are ripe (black spots are perfect) and use cake flour instead of all-purpose for a lighter texture. The coffee grounds shouldn't be wet—drain any excess liquid from brewed coffee.
