Macerate the strawberries: In a bowl, toss sliced strawberries with lemon juice, maple syrup or honey, and half the vanilla. Let sit for 10–15 minutes until they release their juices.
Prep the base: Cube your cake or pancake base into bite-size pieces. Aim for 1-inch cubes so they soak up juices without getting soggy.
Make the protein cream: In a mixing bowl, whisk Greek yogurt, protein powder, remaining vanilla, sweetener, a pinch of salt, and 2 tablespoons milk.
Add more milk 1 tablespoon at a time until it’s thick but spoonable, like whipped cream.
Layer the cups: Add a layer of cake cubes to the bottom of each serving cup or jar. Spoon over some strawberry juices to moisten the cake slightly.
Add cream and berries: Spoon a layer of protein cream over the cake, then a generous spoonful of strawberries. Repeat layers once more if your cups are tall.
Finish and chill: Top with a final dollop of cream, a few strawberry slices, and optional garnishes like mint or lemon zest.
Chill for 15–30 minutes for best texture.
Serve: Enjoy cold. The layers hold well, and the flavors meld beautifully after a short rest.
