First prepare 4 7" cake pans with grease & parchment paper liners.Preheat the oven to 350°F Prepare the cake batter of your choice based in the links above
Divide the batter in half & add the freeze dried strawberry powder to one half
Bake all the cake layers together in the preheated 350°F oven for approximately 22 minutes or when they are springy to the touch when you gently press the centers, or with the toothpick test, insert a toothpick and if it comes out clear it is done!
Cool the cakes in the pans until you can safely touch then without burning yourself then flip them out onto a cooling rack to cool completely.
Prepare the strawberry compote: in a medium heavy bottom sauce pot combine the chopped strawberries & optional cranberries together with the sugar & water if needed.
Cook over medium heat until the cranberries start to pop & the berries are breaking down. Stir often.
Turn the heat to low & let it simmer approx 10 minutes ~ the sauce will naturally thicken as it cools to cold. You can leave it chunky or blend to a puree it is your option
Prepare the garnish for the cake by grinding the golden sandwich cookies in a food processor to medium crumbs, add the dehydrated strawberries & pulse until it is all the size you desire for garnish.
When you are ready to build the cake prepare your vegan whipping cream
OR prepare the white chocolate mousse by melting the vegan white chocolate
Combine the warm plant milk with the agar powder & then bring to a rolling boil to activate the agar.
Add this to the melted white chocolate & whisk as fast as possible to prevent setting!
Next quickly fold in the 2 cups of whipped cream & whisk smooth.
The mousse will set very fast due to the agar, so be sure to have your other ingredients ready to go since you will have to build the cake fairly quickly to make sure the mousse doesn't set.
