• Preheat oven to 325°F (160°C)• 12-cup muffin pan, greased or lined with silicone or paper liners
In a large bowl, whisk together cake flour, unbleached flour, lemon zest, baking powder and salt. Set aside.
Place the eggs, yogurt, butter, vanilla and sugar in the Vitamix container and secure the lid. With the switch on Variable, select speed 1 and turn the machine on. Gradually increase the speed to 7 and blend for about 30 seconds or until smooth.
Pour the egg mixture over the flour mixture and stir until almost moistened. Gently fold in pear just until incorporated.
Scoop the batter into the prepared muffin cups, dividing equally.
Bake in preheated oven for 27 to 30 minutes or until a tester inserted in the center of a cupcake comes out clean. Let cool in pan on a wire rack for 10 minutes, then carefully transfer cupcakes to the rack to cool completely.
Glaze: Place powdered sugar in a medium bowl and whisk in lemon juice and vanilla. If the mixture is too stiff to pour, stir in more lemon juice, 1 tsp (5 mL) at a time, to make a thick glaze.
When the cupcakes are completely cooled, drizzle glaze on top and let dry.
For the most accurate measurements when making baked goods, weigh your dry ingredients. For this recipe, you’ll need 137 g cake flour, 57 g unbleached flour, 200 g granulated sugar and 120 g powdered sugar.
Cake flour gives cakes and pastries a delicate, tender texture because it is very low in gluten.
