Step 1

Soak the cashews and pistachios overnight, or at least 4 hours. Then drain well and add to a blender along with the rest of the ingredients, and blend until the mixture is really smooth. It will look like milk, and that's okay. Taste and adjust Sweet and set aside.

Step 2

You want to convert the cashews into a flour, so add the cashews, cardamom, cornstarch, and saffron in a blender, and blend for 15 seconds, then start pulsing every few seconds. Use a spoon to move the mixture around so there are no cashews lurking in the corners, and pulse a couple of times more until the mixture is a fine meal. If there are any cashew pieces left, remove them, or try to pulse them in by pulsing a couple more times, and then remove any remaining large cashew pieces from the mixture.

Step 3

Transfer to a bowl, add the almond flour, salt, cream cheese, butter, and sugar and mix. Press and mix with a spatula, or use your hands to make a dough.

Step 4

Grease a shallow baking dish, and press this dough onto the dish into a square or rectangle, less than half an inch thick, and even out the edges. You can wet your hands before doing that so that it's not as sticky, or use oil on your hands.

Step 5

Bake at 275 degrees F (135 C) with the fan on(convection) for 25-30 minutes, or until the mixture feels completely dry on top, and has lightened in color. You can also use regular bake if you don’t have convection

Step 6

Take the pan out and let it cool for 10-15 minutes, then slice the cake into an inch or inch and a half big squares, and slightly separate it out. The center will feel very soft, so separate out only if it's not breaking into pieces.

Step 7

Pour the entire sauce mixture all over to submerge the cake.

Step 8

Garnish with pistachios and almond slivers, and let this mixture chill for at least a few hours before serving
