Start by placing a large skillet over medium heat. Add the unsalted butter, allowing it to melt gently without browning.
Once the butter has melted completely, sprinkle in the brown sugar, followed by the ground cinnamon and freshly grated nutmeg. Stir continuously until the mixture becomes bubbly and the sugar has fully dissolved.
Carefully arrange the banana halves in the skillet, cut side facing up. Cook them for about 1-2 minutes or until they start to soften slightly.
Using a spatula, gently flip the bananas to cook the other side for an additional minute, allowing them to caramelize evenly.
Lower the heat to a gentle simmer. Slowly pour in the heavy cream while stirring, then add the pure vanilla extract. Allow the mixture to cook for another minute to meld the flavors beautifully.
Once the sauce is well combined, remove the skillet from the heat and let it sit for a minute to settle.
For serving, place a generous scoop of creamy vanilla ice cream in a bowl or on a plate. Ladle the warm banana sauce lavishly over the ice cream, ensuring each serving is plentiful.
Notes
Serve in deep bowls and garnish with cinnamon or mint for an elegant touch.
