I've made a carrot cake with cream cheese frosting or just a white or yellow cake. How about a cupcake for your son. If you want a fancier cake, I have a flourless chocolate cake recipe. Hopefully nobody has a nut allergy. I have a lot of recipes. You can always do an internet search. I like to use allrecipes.com because people rate the recipes.
For the cake:
2 bars (4 oz. each) Ghirardelli Semi-Sweet Chocolate
1/2 cup butter, softened
3/4 cup sugar (divided)
6 egg yolks
2 teaspoons vanilla
1 1/3 cup finely chopped pecans
1/4 cup dry bread crumbs
7 egg whites (room temperature)
pinch of salt
Melt chocolate in microwave on medium heat for 30 seconds at a time for about 3 minutes (until melted). Be careful not to over cook the chocolate or it will have a burnt flavor. Set aside. Cream the butter, gradually adding 1/2 cup of sugar. Mix until very fluffy. Add egg yolks, vanilla. Beat until creamy. Fold melted chocolate into creamed mixture. Use a food process or blender to chop pecans to a coarse powder. Combine nuts with the crumbs and fold into chocolate mixture. Beat egg whites into chocolate mixture; fold in remaining egg whites. Pour batter into a buttered 9 inch pan lined with parchment paper. Bake at 350 for 40-45 minutes or until the center is firm. Cool. Cake will sink lightly in the center. Run a knife along the edge and gently remove from the pan. Remove the parchment liner. Top with the Glaze and decorate with whipped cream and berries or whole pecans along the edge.
Glaze:
1 bar (4 oz.) Ghirardelli Semi-Sweet Chocolate
1/2 cup heavy whipping cream
1 teaspoon vanilla
1/3 cup finely chopped pecans
Heat the cream until hot over low heat. Add the chocolate, stirring until smooth and thick. Remove from heat. Stir in vanilla. Turn torte, top side down, onto serving plate. Arrange strips of parchment paper under the cake edge to catch excess glaze. Pour glaze over the top and sides of the cake. After a short time, run excess glaze up the sides of the cake. Cover sides of the cake with nuts. Decorate the top as you see fit. Be creative and enjoy!
