Preheat the oven to 350 degrees F.
In a food processor, finely chop walnuts, pistachios, and sugar.
In a mixing bowl, combine pancake mix, cinnamon, nutmeg, vanilla, water (or non-dairy milk), and 1 tbsp melted butter. Gently whisk until just combined, avoiding overmixing.
In a 10-inch skillet, spread 1/4 cup melted butter. Add the pancake mix.
Top with the walnut-pistachio mixture. Bake for 15-20 minutes or until cooked.
Finish by drizzling honey and adding a dollop of crème fraiche. Enjoy your delightful baklava-inspired breakfast!
