prep and Cook Time
- Planning: 10 minutes
- Cooking: 12 minutes
- Total Time: 22 minutes
Yield
Approximately 2 cups of raspberry filling – enough for an 8-inch layered cake or 12 cupcakes.
Difficulty Level
Easy to Medium – perfect for bakers of all skill levels looking to elevate their cakes with fresh fruit fillings.
Ingredients
- 2 cups fresh raspberries (washed and picked over)
- 3/4 cup granulated sugar (adjust to taste)
- 1 tablespoon fresh lemon juice
- 1 tablespoon cornstarch (for thickening)
- 2 tablespoons cold water (to dissolve cornstarch)
- 1 teaspoon vanilla extract (optional, for depth)
- 1 tablespoon honey or agave syrup (optional, for natural sweetness)
Instructions
- Combine raspberries and sugar: In a medium saucepan, gently toss fresh raspberries with the granulated sugar and lemon juice. Let sit for 5 minutes to macerate, allowing natural juices to release and flavors to meld.
- Cook the mixture: Over medium heat, bring the raspberry-sugar blend to a gentle simmer. Stir frequently to break down the fruit, but retain some chunks for texture if desired.
- Prepare the thickener: In a small bowl, dissolve the cornstarch in cold water until smooth. Slowly whisk the slurry into the simmering raspberries to activate thickening.
- Simmer until thickened: Continue stirring and cooking for 3-5 minutes, maintaining a gentle simmer until the filling reaches a glossy, syrupy consistency. Be careful not to overcook to preserve the bright raspberry flavor and vibrant color.
- Finish with flavor: Remove from heat and stir in vanilla extract and honey or agave syrup to balance the tartness and add complexity. Adjust sweetness here if necessary.
- Cool and store: Transfer the filling to a clean bowl, cover with plastic wrap pressed directly to the surface to prevent a skin forming, and chill until ready to use.
Tips for Success: Balancing & Texturing Your Raspberry Filling
- Adjust sweetness gradually: Start with the recommended sugar amount; fresh raspberries vary in natural tartness depending on season and variety.
- Choose your texture: For a smooth filling, gently press cooked raspberries through a fine mesh sieve to remove seeds. For a chunkier delight, leave moast fruit pieces intact.
- Lemon juice is key: It brightens the flavor and helps preserve the vibrant color.
- Natural sweeteners: Honey or agave add a subtle floral note complementing raspberry’s character.
- Make ahead: This filling keeps well refrigerated for up to 5 days or freezes perfectly for longer storage.
