Put the fruit in the blender and grind lightly.

Add the rest of the ingredients, including the ice cubes, and grind till it becomes a smooth puree.

Divide the mixture into individual cups and freeze for an hour.

You can make the dish more elaborate by topping it with a crumble (see below).

Place all ingredients in a baking pan.

Bake approximately 20 minutes in an oven preheated to 350°F (175°F), until the mixture is slightly browned. Stir a few times while baking so that the butter is well combined with other ingredients.

Remove from oven, cool, and crumble.

Sprinkle crumble on the yogurt before serving.
