Preheat the oven to 350°F. I let my daughter Olivia place the parchment paper in the loaf pan while I grease the sides. It makes her feel like she is in charge before we even start mixing.
In a medium bowl, whisk together the [all-purpose flour], [baking powder], and [salt]. Olivia loves whisking because she says it feels like making magic dust.
In a large bowl, beat the [butter] and [sugar] until light and fluffy. This is where I explain to Olivia how air makes the loaf soft and tender. She watches the color change every time.
Beat in the [eggs] one at a time, then mix in the [vanilla extract], [lemon zest], and [lemon juice]. The lemon smell always makes Olivia smile and say it smells like sunshine.
Whisk together the [Greek yogurt] and [milk]. Add the dry ingredients and yogurt mixture to the bowl, alternating and mixing gently. I remind Olivia that gentle mixing keeps the loaf soft, not tough.
In a small bowl, toss the [blueberries] with 1 tablespoon of [flour]. Olivia insists on coating every berry so they do not sink, because science baking is her favorite.
Gently fold the blueberries into the batter. Pour into the pan and bake for 50 to 55 minutes until a toothpick comes out with a few moist crumbs. The waiting part is always the hardest for us.
Let the loaf cool completely. Whisk the [powdered sugar] and [lemon juice], then drizzle over the loaf. Olivia loves zigzagging the glaze so every slice gets some love.
