Ingredients

What you need

Dry

270 g all-purpose flour
1.5 tsp baking powder
0.5 tsp baking soda
0.5 tsp table salt

150 g granulated sugar

Method

Cook by the cues, not just the clock

Prepare

Preheat the oven to 375°F / 190°C and line or grease a 12-cup muffin pan.
Critical cueThe oven should be fully heated before wet and dry ingredients are combined.

Mix separately

Whisk flour, baking powder, baking soda and salt in one bowl. Whisk sugar, oil, eggs, vanilla and sour cream in another.
Critical cueFully combine the wet ingredients now so later flour mixing can stay brief.

Combine gently

Fold dry into wet only until smooth, then fold in blueberries by hand.
Critical cueStop once no dry flour pockets remain.

Portion and bake

Divide among 12 cups and bake until golden and a center tester comes out clean, about 18 to 24 minutes.
Critical cueCheck early; overbaking dries the crumb.

Cool promptly

Remove muffins from the pan as soon as practical and cool on a rack.
Critical cueDo not let finished muffins steam in the hot pan.

Critical checkpoints

Stop here and check

texture

Batter thick but scoopable?

The batter is thick and holds the berries.

Recheck liquid if it is unusually runny.

other

Center just done?

A tester comes out clean or with moist crumbs.

Remove rather than baking for extra color.

other

Dry, flat or sunken?

The crumb is dry, muffins stay flat or centers crater.

Use the matching muffin diagnosis.
