Sieve the flour, milk powder, baking powder and keep aside.

Cream the margarine, butter and powdered sugar along with egg until light and fluffy. Next, add the vanilla essence and salt.

Slowly add the flour mixture and fold until a smooth dough is formed. Pour the dough into the cupcake moulds and bake at 180 degree Celsius for 15-20 minutes.

Once baked, leave the cupcakes to cool. Once cooled, cut the cupcakes at the centre and fill with jelly and fresh strawberries. Frost the cupcakes with butter cream frosting and serve!
