To make each pie pop, lightly press lollipop stick into heart so that it rests in center. Top each round with 1/2 teaspoon lemon curd and a few baking chips. Repeat cutting out hearts with other pie crust; cover each with second heart crust. With fork or lollipop stick, press around edges to seal. Brush tops of pops with beaten egg; sprinkle with granulated sugar. If desired, cut out small hearts from dough scraps and place on top.
