Throw the flour, brown sugar, chilled butter chunks, cinnamon, and salt into a bowl. Mash and crumble the butter into the mix with a fork or cutter until it looks pebbly. Chill in the fridge while you prep the dough.

Using a bowl and mixer, cream the softened butter with the brown sugar and white sugar. Keep going for a couple of minutes until it’s fluffy and smooth. Pop in the vanilla and then the egg, blending until everything comes together.

In another bowl, mix together the flour, baking powder, and salt. Slowly add the dry stuff to the creamy butter mixture bit by bit until they’re just barely mixed in. Don’t overdo it!

Carefully fold in your fresh blueberries. Try to keep the berries whole while mixing lightly so they don’t get all squished.

Scoop out rounds of dough and space them on a baking tray lined with parchment. Add a swirl of blueberry preserve on top of each using a spoon or toothpick.

Pull the crumbly topping from the fridge and sprinkle a generous amount over each dough round. Gently press it into place.
