Heat your oven to 355°F (or 320°F if using convection). Line an 8-inch square baking pan with parchment paper, making sure it hangs over the edges so you can easily lift out the bars later.

Grab a medium bowl and whisk together the sugar, salt, both flours, and almond meal. Pour in your melted butter and stir everything until it looks like wet sand with an even texture throughout.

Dump the crumbly mixture into your prepared pan and press it down firmly with your fingertips to create an even layer. Use the bottom of a glass to smooth it out nicely, then poke holes all over with a fork. Slide it into the oven for 15 to 20 minutes until it turns golden. Let it cool down completely.

Cover your cashews with boiling hot water and let them sit for 30 minutes to soften up. If you're planning ahead, you can soak them in cold water for a few hours instead. Drain them well before the next step.

Toss your drained cashews into a high-speed blender along with the coconut cream, lime juice and zest, sugar, vanilla paste, softened butter, and ginger. Blend on high until it's silky smooth and creamy with no graininess at all. Taste and adjust the ginger kick to your liking.

Add the mango puree, butter, sugar, and cornstarch to a small saucepan over low heat. Whisk constantly while bringing it to a gentle simmer. Let it bubble for just a few seconds, then remove from heat and let it cool.
07 -
Pour your cashew filling over the cooled crust and spread it evenly. Drop spoonfuls of the mango mixture on top, then use a chopstick or knife to swirl it through the filling, creating a pretty marbled pattern.
08 -
Return the pan to the oven and bake for 25 to 30 minutes. You're looking for set edges with a slightly jiggly center that's still a bit soft. Don't overbake or they'll lose that creamy texture.

Let the bars cool to room temperature, then refrigerate for at least 2 hours before slicing. This chilling time is crucial for clean cuts. Lift them out using the parchment paper overhang and slice into 16 beautiful bars.
