Mini Nutella Filled Fluted Cakes

Brown butter (called beurre noisette in French) is made by cooking butter long enough to turn the milk solids and salt particles brown while cooking out any water present. It has more complex flavour than melted or clarified butter. Brown butter is traditionally served with fish, but makes a delicious topping for vegetables such as broccoli. It adds a deep, nutty flavour to sweet items like butterscotch pudding or cream cheese frosting.

But this time, I add the complex and nutty flavour to my mini fluted cakes with this classic French technique.

Ingredients:
3/4 cup      Brown Sugar
3/4 cup      Cake Flour
1/2 tsp      Baking Powder
4 Egg Whites
1/2 cup (100g)      Butter
4 tbsp      Nutella Spread

材料：
3/4 杯      黑糖
3/4 杯      蛋糕粉
1/2 小匙      发酵粉
4 颗      蛋白
1/2 杯 (100克)      牛油
4 大匙      巧克力酱

Methods:
1. Cut the butter into 4 pieces.
2. Over low heat, use a sauce pan, place in the first piece of butter and cook until it melts completely.
3. After the butter has melted, place in the second piece and continue to cook.
4. Follow the same steps for the third and fourth piece of butter. Move the pan around constantly to let it cooks evenly.
5. Once all the butter has melted and browned, turn off the heat and let it cool. Set aside.
6. Preheat the oven in 200˚C / 400˚F.
7. In a large bowl, mix in the flour, brown sugar, and baking power.
8. Add the egg whites into the dry ingredients and beat until smooth and fluffy.
9. Slowly add the brown butter into the batter and whisk until well combined.
10. Spoon the batter into a non-stick mini cake mould about 3/4 full.
11. Bake it until the edges starts to look golden, about 8-10 minutes.
12. Once its baked, use a skewer to poke it out and place in a wire rack to cool.
13. When its cool completely, pip the Nutella into the cake centre. You can feel the pressure from inside when its filled.

做法：
1. 把牛油切成4块。
2. 放第一块牛油进小锅中，用小火煮溶。
3. 第一块牛油煮溶后，放入第二块牛油继续煮溶。
4. 重复步骤将其余的牛油煮溶。期间不停的移动锅子，让牛油煮均匀。
5. 当牛油煮至咖啡色后，熄火备用。
