Preheat oven to 400 degrees F. Mix together flour, baking powder, salt and sugar.
Using a pastry blender, cut in the butter until it looks like coarse crumbs.
Add in cream and stir gently to incorporate. Do not overwork the dough. Fold in blueberries.
Press dough onto a lightly floured surface. Form into a 10 x 3 x 1.25 inch rectangle. Cut the rectangle in half crosswise, then cut each of those pieces into four pieces.
Place on a parchment lined baking sheet and brush with cream. Bake for 15-20 minutes until golden brown. Cool.
Mix together lemon juice, powdered sugar and zest of one lemon. Mix until smooth without any lumps. Drizzle over cooled scones. I like to drizzle them 2-3 times.
Notes
Use cold ingredients Keep your butter and cream nice and cold. This helps create those tender, flaky layers that make a perfect scone.
Don’t overmix the dough Mix just until the dough comes together. Overworking it will make your scones dense instead of light and flaky.
Toss blueberries in a little flour This helps keep them from sinking and prevents too much moisture from bleeding into the dough.
Handle the dough gently Pat (don’t roll) the dough into shape and avoid pressing too hard. Gentle handling = softer scones.
Brush with cream for a golden top A quick brush of whipped cream before baking gives you that beautiful golden, slightly crisp crust.
Cut cleanly for better rise Use a sharp knife or bench scraper and cut straight down—don’t twist—to help the scones rise evenly.
Bake until just golden Keep an eye on them—overbaking will dry them out. You want lightly golden edges and a soft center.
Glaze after slightly cooling Let the scones cool for a few minutes before adding the lemon glaze so it sets nicely instead of melting right off.
