Start by adding sliced strawberries to a bowl and sprinkling them with granulated sugar. I gently toss them to coat evenly. Let them sit for about 10 minutes until they release their juices and become glossy and soft.
In a chilled bowl, I pour in the heavy cream, powdered sugar, and vanilla extract. I whip it until soft peaks form, being careful not to overwhip. The cream should be fluffy and smooth, not stiff or grainy.
I cut the shortcake or pound cake into small, bite-sized cubes. Smaller pieces layer better and soak up the strawberry juices without falling apart. This step makes a big difference in texture.
I start with a layer of cake at the bottom of each glass. Then I add a spoonful of strawberries with some juice, followed by whipped cream. I repeat the layers until the glass is full, finishing with cream on top.
Once assembled, I like to chill the parfaits for about 15 minutes. This helps the layers settle and allows the flavors to meld together nicely. You can also serve them right away if you’re short on time.
