What is a good filling for a chocolate cake?

I'd use Mocha Chocolate Butter cream icing.

Doc HudsonWilton Butter Cream icing

½ Cup solid vegetable shortening

182 Cup Butter or margarine (1 stick)

1 TBS Wilton Clear Vanilla Extract

4 Cups Confectioners Sugar (1 pound)

2 TBS Milk

Wilton Icing Color of choice

Cream butter and shortening with an electric mixer. Add vanilla extract. Gradually add sugar, one cup at the time, beating well on medium speed after each addition. Scrape sides and bottom of bowl frequently. When all the sugar has been mixed in, the icing will appear dry. Add milk and beat at medium speed until light and fluffy. Makes 3 cups icing.

At this point you will have a nice white icing. For colors, use Wilton’s Icing Color Paste of powder. Use a toothpick to add the paste to the icing and mix well until the color is even. If you need more color, use a new toothpick for each new addition of color.

Keep the icing covered with a damp cloth until reedy to use. For best results, keep the icing bowl in the refrigerator, with a piece of plastic wrap pushed down to be in contact with the icing, when not in use. Refrigerated in an airtight container this icing can be stored for 2 weeks. Rewhip before use.

For Chocolate Butter Cream icing, ad ¾ cup cocoa powder or 3 1-ounce blocks of semi-sweet chocolate melted. Mix well a medium speed and ad two tablespoons of milk.

For Mocha Chocolate Butter Cream Icing, substitute two tablespoons of strong brewed coffee for the milk in the Chocolate Butte Cream icing.

I always put a layer of chocolate icing in the middle,same as the one I ice the outside with.

Another idea would be to add cherry pie filling to the centre. Either one will add moisture.

Happy baking.

Pudding always helps a dry cake.

Fudge icing or chocolate pudding

strawberry or raspbery filling would be good. you could do strawberries and cream for a really decadent cake. or how about a peanut butter cream filling/frosting? or a german chocolate cake-type frosting with nuts and coconut? orange flavouring might be good, too.

Chocolate cream or strawberries. Yum (:

chocolate mousse

chocolate ganache :D the best ever

cherries and a bit of whipped topping
