Step by step

1. Pour the egg whites into the bowl of the stand mixer. Attach the Wire Whip. Turn the Speed Control Lever to 10 and whisk the egg whites until they form soft peaks.

2. Add sugar and whisk until stiff peaks form.

3. Melt the chocolate chips in the microwave on high for about 30 second or until they are just melted.

5. Repeat until all egg whites are incorporated.

6. Spoon into 4 cups or small bowls and put in the fridge to set for 3 hours. Serve with sour cream and raspberries.
