For years, readers have requested if I’ve a raspberry cake filling recipe.

When creating this recipe, I began with my recipe for raspberry sauce.

Only a Few Minutes on the Range
Stir collectively all of the elements—aside from the vanilla—in a saucepan set over medium warmth. Because the combination heats up and the frozen raspberries thaw, use a silicone spatula to smash the berries. This will get simpler because the raspberries soften. By the point it begins to boil, the raspberries ought to be largely crushed, so it’s the combination has a good consistency with no large lumps.
Permit it to boil, nonetheless on medium warmth, for five full minutes, stirring sometimes.
Take away from warmth and stir within the vanilla extract. Take an enormous whiff—it smells wonderful!

Let it cool at room temperature for about quarter-hour after which switch to a heatproof bowl and refrigerate. It’ll proceed to thicken and arrange because it chills.
