Ingredients

Scale

Raspberries and Sweeteners

  • 1 cup fresh raspberries (or thawed frozen raspberries, drained)
  • 1/2 cup granulated sugar (or substitute with honey or maple syrup)

Thickening and Flavor Enhancers

  • 1 tablespoon cornstarch or arrowroot powder
  • 1 tablespoon lemon juice
  • 1/4 cup water
  • Optional: 1 teaspoon vanilla extract

Instructions

  1. Prepare the Raspberries: Rinse fresh raspberries gently under cold water and drain well. If using frozen raspberries, thaw completely and drain any excess liquid to avoid a runny filling.
  2. Combine Ingredients in a Saucepan: In a small saucepan, add the raspberries, sugar, lemon juice, and water. Stir to mix everything evenly before heating.
  3. Heat and Thicken the Mixture: Place the saucepan over medium heat and bring the mixture to a gentle boil. In a separate small bowl, dissolve the cornstarch in 1 tablespoon of cold water. Slowly whisk this mixture into the boiling raspberries, stirring constantly until the filling thickens to a glossy, slightly thick consistency, about 2 to 3 minutes.
  4. Add Final Flavor Enhancements: Remove the pan from heat and stir in the optional vanilla extract if using. Allow the filling to cool at room temperature, during which it will thicken slightly more to the perfect spreadable texture.

Notes

  • Use ripe, bright, and plump raspberries for best flavor and color.
  • Strain the filling through a fine sieve if a seedless texture is preferred.
  • Avoid overcooking to prevent the filling from becoming runny instead of spreadable.
  • Cool the filling completely before using to avoid melting frosting or cake layers.
  • Store leftovers in airtight containers in the refrigerator for up to 5 days.
  • Freezes well for up to 2 months; thaw overnight in the refrigerator before use.
