In a large bowl, toss bananas with lemon juice. Melt butter in a large skillet over medium-high heat. Stir in brown sugar. Cook, KITCHEN TIPS stirring, until sugar has dissolved, about 1 minute.
Add bananas to skillet and cook, basting and gently turning often with a large spoon, until bananas become softened around edges, about 3 minutes. Sprinkle cinnamon on top. Serve bananas, slightly cooled, on their own or with vanilla ice cream and almonds, if desired.
