Use ripe bananas with brown spots for best flavor. Press plastic wrap directly on pudding surface to prevent skin. For thicker pudding, cook a bit longer while stirring. Frozen bananas can be used but may alter texture. Substitute 1 cup milk with heavy or coconut cream for extra creaminess. Variations include coconut milk and shredded coconut, adding cocoa powder for chocolate flavor, or using plant-based milk and vegan substitutes for a vegan version. Store leftovers in airtight container refrigerated up to 3 days; wafers soften over time.
