Preheat the oven to 325º F. Lightly grease your loaf pan, unless it's an uncoated stoneware pan.
Combine the butter, brown sugar, and vanilla extract in a medium bowl. Mix by hand until smooth, about 2 minutes. Or use a stand or hand mixer on low speed for 1-2 minutes until the mixture is smooth.
Stir in mashed bananas and eggs. Combine until smooth, though there might be small lumps of banana. Add Bisquick baking mix, 1/2 cup at a time, stirring in between. Then add nuts, if using.
Pour the banana bread mixture into the prepared loaf pan. Smooth the top before baking.
Bake at 325º F for 45-55 minutes or until a toothpick inserted into the middle of the loaf comes out clean. If the banana loaf gets too brown, cover it with foil during baking.
Allow bread loaf to cool for 10 minutes in the pan before removing and slicing to serve.
Notes
For extra moist banana bread, use overripe bananas with plenty of brown spots. They’re sweeter and blend into the batter effortlessly, enhancing the flavor and texture.
Don’t have any ripe bananas? Not a problem! You can soften bananas quickly by placing them on a microwave-safe plate, covering them with a damp paper towel, and microwaving on high power for 30 seconds. This softens the banana, making it easier to mash.
However, keep in mind that the banana is not quite as ripe, so your bread may not be as sweet. To adjust for this, just add a bit more sugar or honey to the Bisquick banana bread recipe.
Recipe Variations:
Add chocolate chips or swirl some Nutella or peanut butter for a delicious twist.
For banana nut bread, add 1/2 cup chopped walnuts or pecans to the banana bread batter before baking for extra crunch. You may also add raisins or cranberries.
For a healthier banana bread recipe, add 2 tablespoons of ground flaxseed or chia seeds to the batter.
Make it gluten-free by replacing traditional Bisquick with gluten-free Bisquick baking mix.
Storing Instructions:
Let the Bisquick banana nut bread cool completely before storing it. To store, wrap it in plastic wrap or store it in an airtight container. It will keep at room temperature for up to 5 days.
You can also put them in the fridge for up to 5 days or freeze them for up to 3 months.
To reheat, put the slices in the microwave or oven until warm.
