Strawberry Cake Filling (from Allrecipes.com)
 
Makes 2-3 cups of filling
Ingredients
  • 1 cup water
  • 3 TBSP cornstarch
  • 2½ cups frozen strawberries, cut into small pieces
  • ¾ cup white sugar
Instructions
  1. In a large saucepan, whisk together the water and cornstarch. Add the strawberries and sugar to the water.
  2. Cook over medium heat for about 10 minutes, stirring constantly, until the mixture is thick and transparent.
  3. Allow to cool to room temperature before spreading onto cake.
Notes
Just a tip for filling cakes: make a wall of buttercream frosting along the edges of the cake by piping frosting using a fairly large tip. Then spoon the filling inside the walls. This way, the filling will not leak out the sides.
