Filling Ingredients

  • 1 cup fresh or frozen raspberries
  • 2/3 cup granulated sugar (adjust to taste)
  • 1 tablespoon cornstarch
  • 1/2 cup water
  • 1 tablespoon freshly squeezed lemon juice

Instructions

  1. Prepare the Raspberries: Gently rinse fresh raspberries under cold water. If using frozen raspberries, no need to thaw completely—just have them ready for cooking.
  2. Combine Sugar, Cornstarch, and Water: In a small saucepan, whisk together the sugar, cornstarch, and water until smooth to create the thickening base for the filling.
  3. Cook the Mixture: Place the saucepan over medium heat and stir constantly until the mixture thickens and becomes translucent, about 3 to 4 minutes.
  4. Add Raspberries and Lemon Juice: Stir in the raspberries and freshly squeezed lemon juice. Cook gently, mashing some berries with the back of a spoon, until the filling thickens further and develops a glossy appearance.
  5. Cool and Store: Remove the filling from heat and allow it to cool to room temperature before spreading over cake layers or filling cupcakes.

Notes

  • Use ripe raspberries for the best natural sweetness and vibrant flavor.
  • Constantly stir during cooking to prevent lumps and scorching.
  • Adjust thickness by adding water if too thick, or cooking longer if too thin.
  • For a seedless texture, strain the filling through a fine mesh sieve after cooking.
  • Cool filling completely before spreading to avoid melting frosting or sliding layers.
  • Store leftovers in an airtight container in the refrigerator for up to 5 days; stir before use.
  • The filling can be frozen for up to 2 months; defrost overnight in the refrigerator and stir before reheating.
  • Reheat gently on stovetop or microwave while stirring to maintain smoothness.
