Gâteau au chocolat fondant-oozing chocolate cake

Melts in your mouth & your plate! Chocolate cake is a birthday favorite, so try this recipe out! The cake must be "undercooked", as the whole point is that when cut the center oozes chocolate all over. We like this with whipped cream or à la mode.
TIP: use good quality dark chocolate, not chocolate chips. Zap in microwave with butter to melt it.

8 0z dark chocolate
5 tbsps flour
6 oz sugar
6 oz butter
4 eggs

Preheat oven to 400°F.
Grease & flour a spring form pan.
Melt chocolate with butter.
Seperate yolks from whites.
Add yolks to chocolate mixture while whisking. Whisk in flour & set aside.
Beat egg whites until stiff, gradually adding sugar.
Fold egg whites into chocolate mixture.
Pour into pan & bake about 30 minutes. Check that the center is not too cooked, it should be solid on the edges but not the center.
Serve right away or just warm.
