Use a kitchen scale to measure the ingredients. I love using a kitchen scale, it makes a better end product.
Cream together butter and sugar. Add almond flour and regular flour.
Add egg and amaretto. Mix until combined.
Press the pie dough in a tart pan. Peel and slice the pears into thin slices. I like to keep the slices together, they look so beautiful when you lay them into the tart pan.
Spread the almond filling into the bottom of the tart.
Press the pears into the filling. Bake in a 350-degree oven for 35 to 45 minutes. The filling will puff a little and the crust will be golden brown. Let cool in pan for 10 to 15 minutes, then remove from pan. Let cool completely.
Make the cream by whipping mascarpone and heavy cream until thick, add powdered sugar, amaretto, and vanilla bean paste.
Sprinkle tart with powdered sugar and serve with amaretto cream.
