Step 1- Make the Crust
Line a 9-inch square pan with parchment paper. In a medium bowl, combine the graham cracker crumbs, melted vegan butter, and sugar, stirring until it resembles moist crumbs. Press the mixture firmly and evenly into the bottom of the pan, then place it in the fridge to firm up while you make the filling.
Step 2- Beat the Cream Cheese
In the bowl of a stand mixer using the whisk attachment, beat the vegan cream cheese until smooth, about 1 minute. This step matters lumpy cream cheese means lumpy bars.
Step 3- Add the Remaining Filling Ingredients
Add the coconut cream, powdered sugar, vanilla, and lemon juice to the cream cheese. Beat until creamy and fully smooth, scraping down the sides of the bowl as needed.
Step 4- Assemble the Layers
Pour the filling over the chilled crust and spread it evenly with a spatula. Top with the diced strawberries, distributing them evenly across the surface.
Step 5- Make the Crumb Topping
In a small bowl, stir together the crushed graham crackers, brown sugar, and melted vegan butter until the mixture turns crumbly. Sprinkle this crumble generously over the strawberries.
Step 6- Chill Until Set
Transfer the pan to the refrigerator and chill for at least 5 hours, though overnight gives the best texture. The bars need this full chilling time to firm up properly since there's no baking involved to set the filling.
Step 7- Slice and Serve
Use the parchment paper to lift the bars out of the pan, then slice into 16 squares. Serve chilled straight from the fridge for the best texture.
