Wash your strawberries under cold water. Pat them dry. Remove the leaves, and slice them. Set aside on a kitchen towel (This will allow the towel to absorb the extra liquid).
In a small sauce pan, bring the milk and butter to a warm temperature. It should feel nicely lukewarm. Set aside.
In your mixing bowl, beat together the eggs and sugar until light and fluffy (about 2 minutes on medium high speed). Add your milk/butter mixture. Then, slowly incorporate the flour.
Pour your batter into the Flexipan®. Add your strawberries. Sprinkle your Vanilla sugar top.
BAKE!
Bake for 30 minutes at 400F/200C. (Every oven heats differently, monitor your clafoutis from 25min).
Once your French Strawberry Clafoutis is out of the oven, let it cool down completely in the mold. Cover with a plastic wrap and refrigerate for at least a couple of hours. Then, Unmold, Serve and Enjoy! Bon Appétit!
