Banana-Nut Scones

1 . Stage

Preheat the oven to 400 degrees F (200 degrees C). Grease a cookie sheet.

2 . Stage

Place bananas in a large bowl; beat with an electric mixer until mashed. Add brown sugar, yogurt, egg, and vanilla, beating until smooth. Add cinnamon, baking powder, and salt, beating to combine. Add flour, 1 cup at a time, beating just until combined after each addition. Do not overmix.

3 . Stage

Grate chilled butter into batter using a cheese grater. Beat to combine. Fold in walnuts using a rubber spatula. Drop batter by generous 1/4 cupfuls onto the prepared cookie sheet.

4 . Stage

Bake in the preheated oven until edges and tops of scones are golden and a toothpick inserted in the center of a scone comes out with only crumbs, 17 to 20 minutes.

5 . Stage

When scones have a few minutes left in the oven, combine maple syrup and butter for glaze in a small saucepan over medium heat. Cook until butter melts completely; do not boil. Remove from heat. Add just enough confectioners' sugar, whisking in a small amount at a time, to reach desired consistency for glaze.

6 . Stage

Drizzle glaze over scones using a spoon or whisk.
