Combine the almond flour, sifted einkorn flour, salt, baking powder, and baking soda in a bowl. Set aside.
Beat the eggs, egg white, and sugar on high speed for 2 to 3 minutes until thick and pale in color. Add the vanilla, melted butter, and oil and mix until well incorporated.
Fold in the flour mixture until well combined.
Pour the batter over the pears.
Bake at 350°F for 55 to 75 minutes until the cake springs back when lightly pressed.
Let the cake cool in the pan for 10 to 15 minutes then run a knife around the edges of the pan to loosen the cake. Flip the cake pan upside down onto a wire rack and gently shake the pan to remove the cake. Peel off the parchment paper and let the cake cool for 1 to 2 hours.
