Instructions

  1. 1

    Pulse almonds in food processor until chopped, add brown sugar and 1 tablespoon flour, process briefly, then add butter and pulse until crumbly.

  2. 2

    Stir oats into almond mixture and set aside.

  3. 3

    Combine flour, sugar, baking powder, baking soda, salt, and lemon rind in a large bowl and create a well in the center.

  4. 4

    Whisk buttermilk, oil, and egg together, pour into well, and stir just until combined.

  5. 5

    Toss blueberries with remaining flour and gently fold into batter.

  6. 6

    Divide batter among greased muffin cups, filling two-thirds full, then sprinkle streusel mixture evenly over each.

  7. 7

    Bake until golden brown and a toothpick inserted in center comes out clean.

  8. 8

    Cool in pan briefly, then turn out onto wire racks to cool completely.

Tips

Tip 1

Coat frozen blueberries in flour before folding to prevent sinking and uneven distribution throughout the muffin batter.

Tip 2

Fill any empty muffin cups one-third full with water to ensure even baking and prevent the pan from warping.

Tip 3

Don't overmix the batter once the flour is added; lumpy batter produces tender muffins while overmixed batter becomes dense and tough.

FAQ

Can I use milk instead of buttermilk?

Yes. Combine 3/4 cup milk with 1/2 tablespoon lemon juice or white vinegar and let sit 5 minutes to curdle slightly before using as a buttermilk substitute.

Can I freeze the batter?

Freeze prepared batter in muffin cups up to 3 months, then bake directly from frozen, adding 5-7 minutes to baking time. Streusel topping can be frozen separately and sprinkled on before baking.

How long do baked muffins stay fresh?

Room temperature storage lasts 3 days in an airtight container. Refrigerate for up to 1 week or freeze baked muffins up to 3 months. Thaw at room temperature before serving.
