Line your baking tray with liners and keep them aside depending on what muffin pan or silicone liners you are using. Or spray them with cooking spray.

In a large bowl, sift the flour, baking powder, and salt and keep aside.

In another bowl, whisk the butter and sugar together till it's light and creamy. Add in the eggs and vanilla extract and mix well. Add the flour mixture and milk in batches alternatively to the butter mixture. Add the blueberries and mix well.

Fill your liner up to 3/4 with the batter and bake for 10 to 12 minutes, at 320 degrees F, air fryer setting, or till the toothpick inserted in the middle comes out clean. Once baked, let them cool completely before topping them with frosting.

In a large bowl, cream the butter for 1-2 mins till it's light and creamy. Add the sugar in batches and keep mixing.

Then add the pureed blueberries and mix and decorate your cupcakes as you like.

Plate, serve, and enjoy!
