In a medium sauté pan, melt 1 tsp (5 mL) butter and add half the banana slices. Cook on each side until golden brown, remove from pan and repeat with remaining butter and bananas. Place cooked bananas in a medium-sized bowl with bread; set aside.
In a second medium bowl, whisk together eggs, milk, peanut butter, sour cream, vanilla and honey. Tip: If your honey and/or peanut butter are too firm to whisk, warm them in the microwave or in a pot before mixing them in. Pour over bread-and-banana mixture and fold together.
Place in an 8-in. (20 cm) round baking dish and bake until set, about 35 minutes. Serve warm. If desired, top with a dollop of frozen yogurt and sprinkle with peanuts.
