Line a 9 x 13 inch baking dish with parchment paper.
BASE
Place all the dry ingredients in a mixing bowl and stir to combine. Add the melted butter and mix to form a crumb.
Press the base mix into the bottom of the lined baking tray and smooth with the back of a spoon.
FILLING
Add the cream cheese to mixing bowl with the powdered sweetener and vanilla. Whisk with an electric mixer until just combined.
In a separate bowl, whisk the heavy cream until a soft peak thickness. Fold the cream into the cream cheese and mix with a spatula. Taste for sweetness and decide if you need a bit more or not.
Add the gelatin to a mug and add boiling water. Stir to combine then immediately fold through the filling.
Spoon the filling onto the almond base and level with a spatula. Place in the fridge for 8 hours or overnight to set.
BLUEBERRY SAUCE
Add the berries to a saucepan with water and optional sweetener. Simmer until the berries are just soft, about 5 minutes. Remove from the heat and add the chia to thicken. Allow to fully cool. Place in the fridge to speed this up.
ASSEMBLY
Add the berry sauce to the top. Pop in the freezer for 30 minutes before slicing to make it easier to slice and it’s nice and cold.
