Step 1

Add raw cashews to a mixing bowl and cover with boiling hot water. Let rest for 1 hour (uncovered). Then drain thoroughly.

Step 2

In the meantime, preheat oven to 350 degrees F (176 C) and line an 8x8 inch baking dish with parchment paper (adjust number/size of pan if altering batch size).

Step 3

Add oats, nuts, sea salt, and coconut sugar to a high-speed blender and mix on high until a fine meal is achieved.

Step 4

Add melted coconut oil, starting with 3 Tbsp (45 ml) and adding more if it's too dry. Pulse/stir with a spoon to combine until a loose dough is formed. You should be able to squeeze the mixture between two fingers and form a dough instead of it crumbling. If too dry, add a bit more melted coconut oil.

Step 5

Transfer mixture to parchment-lined baking sheet and spread evenly. Then place parchment paper on top and use a flat-bottomed object, such as a drinking glass, to press down firmly until it’s evenly distributed and well packed. A little may go up the sides, which is good!

Step 6

Bake for 12 minutes, then increase heat to 375 F (190 C) and bake for 5-8 minutes more or until the edges are golden brown and there is some browning on the surface. Remove from oven to cool slightly. Then reduce oven heat to 350 degrees F (176 C).

Step 7

Once cashews are soaked and drained, add to a high-speed blender with coconut cream, arrowroot starch, lime juice and zest, sea salt, and maple syrup. Mix on high until very creamy and smooth.

Step 8

Taste and adjust flavor as needed. I added a bit more zest and maple syrup. It should be very citrusy, and not overly sweet.

Step 9

Pour filling over the pre-baked crust and spread into an even layer. Tap on counter to remove any air bubbles.

Step 10

Bake for 18-23 minutes or until the edges look very slightly dry and the center appears “giggly” but not liquidy.

Step 11

Let rest for 10 minutes, then transfer to refrigerator to let cool completely (uncovered) - at least 4 hours, preferably overnight.

Step 12

To serve, slice and sift with powdered sugar (optional). Store leftovers in the refrigerator, covered, up to 4 days, though best within the first 2-3 days.
