Creating Blueberry Lemon Curd Donut Holes is a straightforward process. Just follow these steps:

1. Preheat your oven to 350°F (175°C). Grease a mini muffin tin with cooking spray or use silicone molds.
2. Combine Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well combined.
3. Mix Wet Ingredients: In another bowl, whisk the buttermilk, egg, melted butter, and vanilla extract until smooth.
4. Combine Mixtures: Slowly add the wet ingredients to the dry ingredients, stirring until just combined. Be careful not to overmix.
5. Fold in Blueberries: Gently fold the blueberries into the batter, ensuring even distribution without breaking them up too much.
6. Spoon Batter: Fill each muffin tin cavity about halfway with the batter. Then, add a small amount of lemon curd in the center, followed by a little more batter to cover it completely.
7. Bake: Place the muffin tin in the preheated oven and bake for 10-12 minutes or until the tops are golden brown and a toothpick inserted comes out clean.
8. Cool: Once baked, remove the donut holes from the oven. Allow them to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
9. Dust with Powdered Sugar: Once they are completely cool, dust with powdered sugar for an elegant finish.

These steps will guide you in creating these delightful donut holes effortlessly.
