Preheat the oven to 350°.
Spray two 8 1/2 x 4 1/2" bread pans with cooking spray and line the bottoms with parchment paper for easy removal.
In a small bowl, mash the bananas and add lemon juice. Set aside.
3 large ripe bananas (heaping 1 c.), 1 Tbsp. lemon juice
In a large mixing bowl, beat the butter and sugar until well creamed.
1/2 c. butter, softened (oil or margarine), 1 c. sugar
Add the eggs and vanilla and mix well.
2 large eggs, 1 tsp. vanilla extract
Add the mashed bananas and mix.
Add the dry ingredients and mix only to combine.
2 c. all-purpose flour, 1 tsp. baking soda, 1/4 tsp. salt
Stir in the nuts if desired.
1/2 - 3/4 c. chopped walnuts or pecans (optional)
Divide between the two prepared loaf pans and bake for 42 - 48 minutes or until a toothpick comes out with only a few crumbs.
Remove from the oven and let the loaves rest in the pans for about 10 minutes. If needed, use a knife around the edges to loosen the loaves, and they should slide right out.
Cool, slice, and enjoy. Place into airtight bags or containers. This bread freezes well, to keep some fresh for later.
This bread is best when served at room temperature. However, it only stays good on the counter for about 2 - 3 days (depending on humidity). But you can refrigerate or freeze it to keep it longer. Just let it come back to room temperature before serving.
