Banana Bread Brownies Ingredients
For the Brownies
• Sugar – Sweetness is key; you can reduce it for a less sweet treat.
• Sour Cream – Adds necessary moisture and richness; Greek yogurt is a suitable substitute.
• Butter – This ingredient enriches flavor and texture; margarine or a non-dairy option can work as well.
• Eggs – Acts as a binding agent; consider using flax eggs for a vegan version.
• Ripe Bananas – Provides natural sweetness and moisture; 3 to 4 medium ripe bananas work perfectly, or substitute with applesauce for lower calories.
• Vanilla Extract – Essential for flavor; opt for pure extract for the best results.
• All-Purpose Flour – Gives structure; whole wheat flour can be used, but it may change the texture slightly.
• Baking Soda – A leavening agent that helps brownies rise; check freshness for best results.
• Salt – Enhances overall flavor.
• Chopped Walnuts (optional) – Adds crunch and a nutty flavor; feel free to substitute with pecans or omit for nut-free brownies.
For the Frosting
• Brown Butter – This is what brings richness and flavor to the frosting; regular melted butter can be a quick fix if needed.
• Powdered Sugar – Ties the frosting together with sweetness and structure; a sugar alternative can be used for a healthier option.
• Milk – Necessary for frosting consistency; non-dairy milk is a great dairy-free substitute.

Make Ahead Options
These Banana Bread Brownies are perfect for meal prep!

Expert Tips for Banana Bread Brownies
-
Fresh Bananas Matter: Ensure your bananas are overripe; the sweetness enhances flavor and moisture while keeping your Banana Bread Brownies soft.
-
Don’t Overmix: Mix just until the flour is incorporated to avoid tough brownies. Overmixing develops gluten, leading to a denser texture.
-
Check Oven Temperature: Ovens can vary in accuracy; invest in an oven thermometer to ensure your brownies bake evenly.
-
Cool Before Cutting: Allow the brownies to cool slightly before slicing to maintain their structure and avoid crumbling.
-
Watch the Brown Butter: When making the frosting, stay close to the stove; brown butter can turn from perfect to burnt very quickly!

Banana Bread Brownies Recipe FAQs
How do I know if my bananas are ripe enough?
Absolutely! The best bananas for this recipe should have a deep yellow color with plenty of brown spots. Ideally, they should be quite soft and almost mushy, which indicates maximum sweetness and moisture. If you’re in a hurry, you can ripen bananas quickly by placing them in a paper bag with an apple overnight.
What’s the best way to store leftover Banana Bread Brownies?
For sure! Store your brownies in an airtight container at room temperature for up to 3 days if you prefer them soft and chewy. If you want to keep them fresh longer, place them in the fridge for up to a week. Just remember to let them sit at room temperature for a bit before enjoying again!
Can I freeze Banana Bread Brownies?
Yes, you can! To freeze, wrap your brownies tightly in plastic wrap and then in aluminum foil to prevent freezer burn. They can be stored in the freezer for up to 3 months. When you’re ready to indulge, thaw them overnight in the fridge and warm in the microwave for 10-15 seconds for that fresh-baked experience!
What can I do if my brownies come out too dry?
Very! To avoid dryness, ensure not to overbake. Check for doneness a few minutes before the suggested baking time; a toothpick should come out with a few moist crumbs. If they’re already baked and seem too dry, try serving them with a scoop of vanilla ice cream or a drizzle of warm chocolate sauce to enhance moisture and flavor.
Are Banana Bread Brownies suitable for people with nut allergies?
Absolutely! If you’re catering to nut allergies, just omit the walnuts from the recipe. Feel free to customize them by adding chocolate chips or dried fruit instead for texture and flavor without the nuts! Always double-check ingredient labels to ensure they are nut-free.
How long can I keep the brown butter frosting?
Great question! The brown butter frosting can be stored in an airtight container in the fridge for up to a week. Just re-whisk it before spreading, as it may thicken when chilled. You can also freeze it for up to 3 months; just let it thaw in the fridge overnight before using!
