Preheat oven to 300F and line a work surface with a silicone mat or a large piece of parchment paper.
In a large bowl, whisk together the almond flour, cocoa powder, sweetener, baking powder and salt. Stir in the egg, melted butter and vanilla extract until the dough comes together.
Turn the dough out onto prepared work surface and pat into a circle. Top with another piece of parchment and roll out into a circle about 11 or 12 inches in diameter. Press and crimp the edges to form a nice even circle.
Slide the silicone mat or parchment paper onto a bakign sheet and bake about 30 minutes, until firm to the touch.Remove from oven and let cool.
Cream Cheese Frosting:
In a medium bowl, beat the cream cheese with the sweetener until smooth. Beat in the cream and vanilla extract until well combined. Add additional cream if your frosting is too thick.
Spread the frosting over cooled crust.
Arrange the berries decoratively overtop.
In a microwave safe bowl, heat the cream on high until bubbling (this should only take about 30 second). Add the chocolate and let stand 2 mintues to melt, then whisk together until smooth.
Drizzle the chocolate sauce over the cookie pizza. Chill until set, about 20 minutes.
Note: Bocha Sweet is not widely available in all areas outside the US. Please know you can make this same recipe with other sweeteners. The frosting should be made with a powdered (confectioners style) sweetener for best results.
