In the bowl of a stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy. Add the sugar and mix at high speed to incorporate. Add the almond flour and beat on medium speed until thoroughly combined. Add the salt, egg and milk and mix until light and fluffy.

Fire up your oven, aiming for 850 to 950°F (450 to 500°C) on the baking stone inside. Use an infrared thermometer to quickly and accurately check the temperature of the stone.

Place a dough ball on your lightly floured work surface. Push the air from the center out to the edge with your fingers. Stretch the dough out to a 12-inch-round base, then lay the stretched dough over your lightly floured pizza peel. Add a drizzle of olive oil to help flatten the dough while cooking. Slide the pizza off the peel and into the oven. Cook for 60 seconds, until the dough is parbaked. The dough should begin to brown, but still have plenty of blonde spots.

Remove from the oven, then spread ⅓ of the frangipane onto the warm dough using a spatula. Layer the pear slices on top and return to the oven, cooking until the frangipane turns golden brown. Remove from the oven one final time, then drizzle on the Nutella, reduced pear syrup and a sprinkle of flaky sea salt. Let cool slightly so the frangipane sets up, then slice and serve.
