This black forest trifle has all the components of a black forest cake - moist chocolate sponge, smooth chocolate pudding, tart and sweet cherry pie filling and light and fluffy whipped cream. All completely homemade!
To make the cherry filling, combine the sugar, corn starch, lemon juice, and salt in a saucepan over medium heat. Mix until cornstarch has dissolved, then add cherries. The cherries will slowly release their juices.
