05 - 1/2 cup light brown sugar, packed
06 - 1/4 cup granulated sugar
07 - 1/4 cup canola or vegetable oil (or liquid-state coconut oil)
08 - 1/4 cup sour cream (or lite/Greek yogurt)

11 - 1 cup all-purpose flour
12 - 1/2 teaspoon baking powder
13 - 1/2 teaspoon baking soda
14 - 1/4 teaspoon salt
# Directions:
01 - Preheat oven to 350°F. Line an 8×8-inch baking pan with heavy-duty aluminum foil and spray with cooking spray. Set aside.
02 - In a large saucepan, melt butter and brown sugar over medium heat, stirring constantly until smooth. Bring to a gentle boil and cook for 30 to 45 seconds. Pour caramel evenly into prepared pan.
03 - Place sliced bananas in a single even layer over the caramel, leaving about 1/2 inch between slices. Set aside.
04 - In a large bowl, whisk together egg, brown sugar, granulated sugar, oil, sour cream, and vanilla extract until fully blended.
05 - Stir mashed bananas into the wet mixture until evenly incorporated.
06 - Add flour, baking powder, baking soda, and salt. Stir gently until just combined without overmixing.
07 - Pour batter carefully over banana slices in the pan, smoothing the top with a spatula if necessary.
08 - Bake for 42 to 45 minutes until the center is set and a toothpick inserted comes out clean or with a few moist crumbs.
09 - Cool cake in pan on a wire rack for at least 3 hours. To invert, lift cake using foil overhang, place cutting board on top, and flip onto serving platter.
10 - Slice and serve as desired. Optional accompaniments include whipped cream or vanilla ice cream.
