Lemon cupcakes baked on egg whites

Those lemon cupcakes were delicious. Light, fluffy, tangy and sweet at the same moment. I baked them as I had plenty of egg whites leftover. I wasn't expecting them to be so nice. I truly recommend them :) The recipe comes form this website. 

Ingredients for 9 cupcakes:

• 4 egg whites
• 1/2 cup of sugar
• 2/3 cup of flour
• 70g melted butter or margarine
• lemon zest

Preheat the oven to 170C. Line muffin tin with paper cases.

Melt the margarine/butter and set aside to cool down. 

Beat the egg whites and sugar until stiff. Beating continuously pour the melted butter/margarine into the egg whites. When ready gently fold in the flour and freshly grated lemon zest. 

Spoon the batter into paper cases, filling them 2/3 full. Bake in preheated oven for 25 minutes.

When baked transfer to the wire rack and cool them down. In a meantime prepare the icing.

Icing:

• 1 cup icing sugar
• lemon juice
• yellow food colouring
• white sprinkles to decorate

 In a bowl mix the icing sugar, lemon juice and food colouring until smooth and thick. Spread the mixture over cupcakes tops and sprinkle with white sprinkles. Enjoy !
