Blueberry Crumb Muffins (Print Version)

# Ingredients:

→ Crumble Topping

01 - 1/4 cup of either salted or unsalted butter, melted
02 - A dash of cinnamon (1/2 teaspoon)
03 - 1/2 cup of plain flour (72g)
04 - Half a cup of granulated sugar (112g)

→ Muffin Batter Base

05 - 3/4 cup granulated white sugar
06 - 1/3 cup melted butter without salt (roughly 5 tablespoons)
07 - A big pinch of kosher salt (1/4 teaspoon)
08 - 1 whole egg
09 - 2 cups fresh or frozen blueberries
10 - 2 teaspoons baking powder
11 - 1 and 1/2 cups of all-purpose flour (212g)
12 - The peel of 2 lemons (or mix lemon and orange zest)
13 - 2/3 cup of tangy buttermilk

# Instructions:

01 - Set your oven to 375°F and line a 12-cup muffin tray.
02 - Mix sugar, flour, and cinnamon in a small bowl. Pour in melted butter, then use a fork to stir until it forms clumps. Pop it in the fridge to chill.
03 - In a large bowl, whisk together baking powder, flour, lemon zest, sugar, and salt.
04 - Whisk together the egg, melted butter, and buttermilk in a separate bowl. If it looks odd, that's normal—don't worry!
05 - Add wet ingredients into the bowl with the dry mix. Stir until barely mixed—it’ll look lumpy, and that’s fine.
06 - With a gentle hand, fold the blueberries into the batter. Don’t overmix, or the batter might turn purple.
07 - Scoop about 3 tablespoons of batter into each muffin liner, filling all 12 cups evenly.
08 - Sprinkle the chilled crumb mixture over the batter on each muffin.
09 - Bake for 28–30 minutes. Muffins are done when their tops are golden and spring back when touched lightly.
10 - Let them cool completely for a couple of hours—they taste even better that way!

# Notes:

01 - Frozen blueberries can be swapped for fresh ones without a problem.
02 - If Meyer lemons aren’t handy, regular lemons or oranges work too.
03 - Your batter should stay lumpy—don’t keep mixing!
