Ingredients:

  • 100g granulated sugar
  • 45g all-purpose flour
  • 60g cold unsalted butter, cubed
  • 1.5 tsp ground cinnamon
  • 375g all-purpose flour
  • 1 tbsp baking powder
  • 0.5 tsp baking soda
  • 0.5 tsp fine sea salt
  • 115g unsalted butter, melted and cooled
  • 100g granulated sugar
  • 100g light brown sugar, packed
  • 2 large eggs, room temperature
  • 240g full-fat sour cream
  • 60ml whole milk
  • 2 tsp pure vanilla extract
  • 300g fresh blueberries
  • 1 tbsp all-purpose flour

Instructions:

  1. Prepare the topping. Combine 100g sugar, 45g flour, and cinnamon in a bowl. Work in 60g cold cubed butter with a fork until it looks like coarse, wet sand. Note: Keep this in the fridge until the oven is ready to ensure the butter stays solid.
  2. Ignite the heat. Preheat your oven to 425°F (218°C) to ensure the initial burst of heat is ready.
  3. Aerate the base. In your largest bowl, whisk 375g flour, baking powder, baking soda, and sea salt. Wait until you see the flour look lighter and fluffier before stopping.
  4. Emulsify the liquids. In a separate bowl, whisk melted butter with both sugars. Add eggs, sour cream, milk, and vanilla, whisking until the mixture is a pale, uniform gold.
  5. Prepare the fruit. Toss the 300g of blueberries with that final tablespoon of flour until they are ghostly white and fully coated.
  6. Merge the masses. Pour the wet mixture into the dry. Use a rubber spatula to fold until only a few streaks of flour remain. Do not overwork it.
  7. Introduce the berries. Gently fold in the floured blueberries with two or three large sweeps of the spatula.
  8. Fill the tins. Divide the batter into a 12 cup muffin tin. The batter will be thick, almost like a soft dough.
  9. Crowning achievement. Pile that chilled crumb topping generously onto each muffin. It will look like too much, but it’s not.
  10. The Temperature Pivot. Bake at 425°F (218°C) for exactly 5 minutes until the tops have sprung upward, then reduce to 350°F (177°C) for 18 to 20 minutes.
