In a heavy bottomed pot, add sliced plums, pitted and halved cherries, honey, thyme, salt and lemon. Simmer on medium-low heat until reduced and thickened, about 20-25 minutes, stirring frequently. Let chill completely in the refrigerator- ideally overnight.
Bake the white cake unless you are using store-bought. I baked a grain-free Simple Mills Vanilla Cake.
When you are ready to assemble the trifle, make the berry whipped cream. In a large bowl, add the heavy cream. Whip until medium firm peaks emerge. Stir in fruit jam and vanilla bean paste and continue to whip until firm peaks emerge.
To an 8-inch trifle dish, add half of the cake torn in bite-sized chunks to the bottom in an even layer. Next, add half of the chilled Plum Cherry Compote in an even layer. Next, add half of the Berry Whipped Cream.
Continue by adding the second half of the cake, compote and whipped cream.
Smooth top and garnish with sliced plums and cherries. Chill until ready to serve. Trifle can be made up to 1 day in advance covered well in the refrigerator.
