Spray a 9x9-inch baking dish with nonstick spray.
Place half of the lady fingers on the bottom of the pan, side by side. I used 10 on the bottom, 2 rows of 5.
20 soft ladyfingers
In a large bowl, using a hand mixer, beat the heavy cream until soft peaks form, about 3-4 minutes.
1½ cups heavy cream
Beat in the mascarpone, ½ cup sugar, vanilla, and 2 tablespoons Chambord. Mix until fully combined and smooth. Set aside.
8 ounces mascarpone cheese, 1 cup granulated sugar, 1 teaspoon pure vanilla extract, 5 tablespoons Chambord raspberry liqueur
In a separate small bowl, stir together the jam/jelly and the remaining 3 tablespoons Chambord. Set aside.
⅔ cup strawberry jam or jelly
In yet another bowl, mix together all of the fruit with ½ cup sugar. Stir to coat all the fruit; macerating the fruit and allowing some juices to form. Set aside.
1½ cups sliced fresh strawberries, 1 cup fresh raspberries, ½ cup fresh blueberries
Start by smoothing half of the cream mixture over the ladyfingers. Use a spatula to smooth out the layer. Top with half of the jam mixture and use a fork to incorporate the jam into the cream. Top with half of the fruit.
Repeat the layers, starting with ladyfingers, cream, jam, then fruit.
Cover and refrigerate for a minimum of 4 hours.
Serve cold.
