Preheat oven to 400° F. Give each parchment paper muffin cup a spritz with flour based cooking spray.
Whisk the self-rising flour, sugar, and salt in a mixing bowl until well combined.
Next, add the eggs, oil, buttermilk, and vanilla in a small bowl and whisk until well combined.
Pour the buttermilk mixture over the dry mixture slowly. Gently stir the ingredients until just mixed.
Repeating Myself! Gently stir the mixture until just mixed! This should take no more than 20 big folding strokes with a rubber spatula. A few lumps are okay. Over working the batter makes a mess of the texture. 😉 🧑🍳
Fold in the blueberries gently and slowly with a rubber spatula.
Using a large ice cream scoop, scoop out big dollops of Buttermilk Blueberry Muffin batter into each of the prepared cupcake wells.
Generously sprinkle with sparkling sugar.
Place in the pre-heated oven and bake for 25 minutes until golden brown and cooked through.
Keep and eye on these beauties! You know your oven best.
Remove from the oven and cool on a cookie rack.
Serve warm or at room temperature. To enjoy the following day, loosely cover the muffins in a container with a lid.
