Ingredients
 

Crumb Topping

  • ½ cup all-purpose flour, fluffed, spooned and leveled
  • ½ cup almond flour
  • cup granulated sugar
  • ¼ tsp coarse Kosher salt (if using table salt, use half the amount)
  • 2 tbsp chopped almonds
  • ¼ cup unsalted butter, melted

Muffin Batter

  • 1 ¾ cups all-purpose flour, spooned and leveled
  • ½ cup granulated sugar
  • 2 tsp poppy seeds
  • 1 ½ tsp baking powder
  • ½ tsp coarse Kosher salt (if using table salt, use half the amount)
  • 1 cup sour cream or plain, unsweetened Greek yogurt
  • ½ cup whole milk
  • ½ cup unsalted butter, melted
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 tsp almond extract

Instructions
 

Getting Ready

  • Preheat the oven to 375 F, and position a rack in the center of the oven.
  • Line a standard muffin pan with 12 paper liners, and lightly spray the liners with non-stick baking spray.

Crumb Topping

  • In a bowl, combine the all purpose flour, almond flour, sugar, salt and chopped almonds. Add the melted butter and stir until moistened and crumbly.
  • If the topping seems too moist, add a little more flour, 1 tbsp at a time. Set aside until needed.

Muffin Batter

  • In a bowl, sift together the flour, sugar, poppy seeds, baking powder and salt.
  • In a separate bowl, whisk together the sour cream, milk, melted butter, eggs, and vanilla and almond extracts. Add the liquid ingredients to the dry, and stir together just until moistened.
  • Divide the batter between the muffin cups, filling them nearly full.
  • Scoop the crumb topping onto the batter, and lightly press it in. The cups will be very full.

Bake

  • Bake the muffins on the center oven rack for about 20-22 minutes, until the tops spring back when gently touched an a toothpick or cake tester inserted comes out clean.
  • Cool in the pan for 5 minutes, then use a spoon to lift the muffins out of the pan onto a cooling rack. Cool for 10 minutes, then serve warm.

Notes

Store leftover muffins in an airtight container at room temperature for up to 3 days.
