Valentine Surprise

Ingredients

• 1 package dark chocolate cake mix 
• 1/2 cup sugar 
• 1/4 cup light corn syrup 
• 2 tablespoons water 
• 2 egg whites; room temperature 
• 1 teaspoon vanilla 
• 1 cup sliced strawberries 
• 1 cup chocolate chips 
• 1/4 cup shortening 
• 3 tablespoons light corn syrup 
• 2 tablespoon plus 1/2 teaspoon water 

Prepare cake according to package directions using a greased and floured 9 inch heart shaped pan at least 3 inches deep. (Or bake in 2 layer pans). Remove from pans to wire rack; let cool. 
For filling:  
Combine sugar, corn syrup and water in saucepan. Cover: bring to a rolling boil over medium heat. Uncover; boil rapidly until mixture reaches 242°F on candy thermometer. Meanwhile, beat egg whites until stiff. Slowly add hot syrup mixture to egg whites while beating on medium speed of electric mixer. Add vanilla. Beat on high speed of electric mixer. Add vanilla.  
Beat on high speed until stiff peaks form.   
Fold in strawberries. (Can be made without strawberries.) If cake has been baked in layers, stack layers. Slice off approximately 1/2 inch of the top of the cake; reserve.  
Scoop out inside of cake to within 1 inch of the sides. Reserve removed cake for another use. Fill hollowed out cake with filling.   
Replace top.           
For glaze;  
In top of double boiler, combine chocolate morsels, shortening, corn syrup and water. 
Heat over boiling water until chocolate and shortening have melted, stirring frequently. 
With filled and assembled cake still on wire rack, slowly pour glaze over cake in a circular motion, smoothing on the sides as glaze drips down with a small metal spatula or knife. Refrigerate until set. Store in refrigerator. Note:  Cake will be shiny chocolate looking, kind of plain until it is cut.
