• Preheat oven to 325 degrees F and grease and flour a bundt pan.
• In a separate bowl whisk the all purpose flour, baking powder, and salt to combine, set aside for later.
• Cream the butter with the paddle attachment in your mixer, gradually add the sugar and beat until light and fluffy 3 to 5 minutes.
• Add the eggs one at a time blending after each to incorporate.
• In a small bowl or measuring cup, add the sour cream, lemon juice, lemon zest, vanilla extract, and lemon extract.
• While mixing on low speed, add the flour mixture alternately with the sour cream mixture to the butter, sugar, & egg mixture. Begin and end with the dry ingredients. (I add the flour mixture three times and the sour cream mixture twice). Mix just until incorporated.
• Fold in the blueberries
• Bake at 325 degrees for 60-70 minutes if using fresh blueberries. Baking times may increase 10-15 minutes or more if using frozen blueberries. Check on the cake as it nears the 1 hour mark and adjust additional time as needed. When an inserted toothpick or skewer comes out clean or with just a few moist crumbs attached, it is ready.
• This recipe makes approximately 8-8.5 cups of batter.

For the Lemon Glaze

• Combine sugar, lemon juice, and a pinch of salt in a small bowl and stir until smooth.
• Drizzle over the pound cake. (I spooned mine into a piping bag with the tip snipped away for more control.) Sprinkle lemon zest over the top. If the glaze is too thin, add a bit more powdered sugar. If it is too thick, add a bit more juice or a touch of milk.
• Garnish with a sprinkling of lemon zest.
