Preheat your oven to 350°F (175°C). Grease and flour a loaf pan.

In a large bowl, cream butter and sugar until light and fluffy (about 3 minutes).

Beat in eggs one at a time, followed by the vanilla extract.

In another bowl, whisk flour and baking powder together. Gradually mix into the butter mixture, alternating with pink lemonade concentrate.

Pour batter into the prepared pan and smooth the top.

Bake for 60-70 minutes or until a toothpick comes out clean. Let cool for 10 minutes before transferring to a wire rack.

For glaze, mix powdered sugar with remaining pink lemonade concentrate until desired consistency; drizzle over cooled cake.
