PERFECT CHOCOLATE CAKE (Serves 16)
1 cup cocoa
2 cups boiling water
1 cup butter
2 ½ cups sugar
1 ½ teaspoons vanilla extract
2 ¾ cups all-purpose flour
2 teaspoons baking soda
½ teaspoon baking powder
½ teaspoon salt
1 cup whipping cream
1 teaspoon vanilla extract
¼ cup sifted powdered sugar
6-ounces semisweet chocolate morsels
½ cup half-and-half
¾ cup butter
2 ½ cups sifted powdered sugar
Combine cocoa and boiling water, stirring until smooth. Set aside to cool. Combine butter, sugar, eggs, and vanilla. Beat at high speed 5 minutes until light and fluffy. Combine dry ingredients. Add to sugar mixture alternately with cocoa mixture, beating a low speed, beginning and ending with flour mixture. Spoon batter into 3 greased and floured 9” round cake pans. Bake at 350° for 25-30 minutes. Cool the layers completely. For filling, beat wiping cream and vanilla until foamy. Gradually add powdered sugar, beating until peaks hold their shape. Chill. Spread between layers. For frosting, combine chocolate morsels, half-and-half, and butter in a sauce pan. Cook over medium heat, stirring until chocolate melts. Remove from heat. Add powdered sugar, mixing well. Set sauce pan in ice, and beat until frosting holds its shape and loses its gloss. Frost cake. Keep refrigerated until about two hours before serving.
Third Grade: SC.3.P.9.1 – Let’s consider the different ways water exists.
What do you see coming off the boiling water?
What is causing the water to change state?
What do we call this change?
What are other physical states of water?
Can the water change back into its original state?
What would cause that change?
