You can make a brilliant chocolate cake with out Dairy and everyone will love it.
It is called a Chocolate Oil cake and you just use Vegetable oil instead of butter, No milk needed it tastes fantastic.
Ingredients
2 cups white sugar 3 cups all-purpose flour 2 teaspoons baking soda 1/2 teaspoon salt 1/2 cup unsweetened cocoa powder 2 cups water 1 cup vegetable oil 2 tablespoons distilled white vinegar 1 teaspoon vanilla extract
Directions
Preheat oven to 350 degrees F (175 degrees C).
In a large bowl, mix sugar, flour, baking soda, salt and cocoa.
Add water, vegetable oil, vinegar, and vanilla. Beat by hand until smooth.
Pour into a 9x13 inch pan. Bake at 350 degrees F (175 degrees C) for 40 minutes, or until toothpick inserted into center of cake comes out clean.
You can decorate the cake however you like and if you want to use butter cream just use Vitalite.
The ready made fondant icing does not have milk in it (double check to be sure)
And I use this all the time aswell.
Party rings are Dairy free and Pink Wafer Biscuits from Tesco's (Again just read the ingredients to make sure nothing has changed)
As for the Bread most of the main brand breads should be fine, there will be some that do contain milk but I have never had an issue buying dairy free bread.
My Daughter is not allowed any Dairy in her diet and never will be able to so I am constantly on the look out for any really good dairy free recipes.
Also along with Mintyneb thankyou for thinking of the child who suffers with allergies, It will be much appreciated I know how hard it is to say no to Party food when all the other kids are eating it, I usualy phone before hand to see what sort of food is being prepared so that I can bring a dairy free alternative that looks just the same.
Hope this helps
