Get your oven hot at 400°F. Coat a 24-cup mini muffin tin completely with cooking spray or melted butter. Make sure you cover the sides and top edges too so nothing sticks later.

Grab a big bowl and mix your flour, sugar, baking powder, baking soda, and salt together with a whisk until everything's well blended.
03 -
In another bowl, whisk together your buttermilk, eggs, melted butter, lemon zest, lemon juice, and vanilla until you've got a smooth mix.

Add the wet stuff to your dry ingredients. Use a spatula to fold them together gently until just mixed. Don't worry about a few lumps - they're actually good for the texture.

Take your fresh blueberries and toss them with 1 tablespoon of the flour you already measured out. This trick keeps them from sinking to the bottom during baking.
06 -
Carefully add the flour-dusted blueberries into your batter. Fold them in gently so they're spread out evenly without mashing up the batter too much.
07 -
Scoop the batter into your muffin tin, filling each cup about three-quarters full. A small cookie scoop works great for getting even portions.

Put the tin in the middle of your oven and bake for 10 to 14 minutes. They're done when they look golden brown on top and a toothpick stuck in the middle comes out clean.

Take the tin out and let it cool on a wire rack for 5 minutes. Then gently run a small spatula around each muffin and lift them out. Move them to the rack to finish cooling. You can eat them warm or at room temp.
