Mash the bananas in a bowl until smooth. Add the lemon juice and optional turmeric for a vibrant color. Mix well.
Cook the Mixture:
In a saucepan, melt the butter over medium heat. Add the mashed bananas and stir for 1-2 minutes until the mixture is fragrant and slightly thickened.
Thicken with Cornstarch:
In a separate bowl, whisk the egg yolks with the cornstarch until smooth. Gradually add the milk while whisking continuously.
Combine and Cook:
Pour the egg mixture into the saucepan with the banana mixture. Cook over medium heat, stirring constantly until the mixture thickens to a pudding-like consistency. This should take about 2-3 minutes.
Cool and Serve:
Remove from heat and let it cool slightly. Fold in the chilled cream gently to achieve a light, creamy texture.
Optional Toppings:
If desired, you can garnish the dessert with a sprinkle of cinnamon, chopped nuts, or a drizzle of honey for extra flavor.
Enjoy:
Serve the creamy banana dessert in bowls or glasses, and enjoy it chilled or at room temperature.
