Preparation

Preheat the oven to 350 degrees F.

In a mixing bowl, whisk together the flour, baking powder, and salt. Set aside.

In a large mixing bowl, using an electric mixer, blend together the melted butter, vegetable oil, and granulated sugar for about 30 seconds until well blended.

Stir in the egg, vanilla, and lemon zest. Blend in the sour cream.

Add in the flour mixture, alternating with buttermilk in two alternate batches, blending until combined after each addition.

Fold in the frozen blueberries. Divide the mixture evenly among 12 paper-lined muffin cups, filling each one to about ¾ full.

Bake the cupcakes for 20 to 25 minutes until a toothpick inserted in the center comes out clean.

Allow to cool completely then frost cupcakes with Lemon Buttercream Frosting and drizzle with chilled blueberry sauce.

For best results, serve immediately after drizzling with blueberry sauce.

Store in an airtight container.

Combine all the ingredients in a large mixing bowl.

Using an electric mixer, blend together for about 1 to 2 minutes until smooth and fluffy.

Tint with yellow food coloring, if desired.

In a medium saucepan, whisk together the sugar and cornstarch. Mix in the blueberries and water.

Bring the mixture to a gentle boil over medium heat, stirring frequently.

Once the mixture reaches a boil, reduce heat and for simmer 3 minutes, stirring frequently.

Pour the mixture into a blender or food processor and blend for about 30 seconds at low speed until smooth.

Cool the mixture completely in the refrigerator or freezer before drizzling over the cupcakes.
