Coffee Strawberry Mousse

In a medium bowl, combine milk, cocoa, coffee and cornstarch and mix well.

In a small non-stick saucepan, over medium-low heat, evenly spray cooking oil for 2 seconds, add milk mixture and cook slowly. Continue to stir while the mixture cooks and becomes creamy. Remove from heat and set aside to cool completely.

Pour creamy milk mixture into a mixing bowl and whip with a hand mixer or blender; remove all lumps. Add the strawberry preserves and whip again; add whipped topping and coffee essence and whip until smooth.

Gently fold in diced banana and garnish with a strawberry slice.
