Preheat oven to 176C | 350F. Spray a 24-count mini muffin pan with cooking oil spray; wipe over excess with paper towel and set aside. Alternatively, use a cake pop tray or cake pop maker.

In a large bowl, whisk all of the dry ingredients together. Make a well in the centre and add the oil, egg, vanilla and milk. Whisk the batter until smooth and lump free.

Spoon the batter (about 2 teaspoons) into each muffin hole, filling to to ¾ full. Bake for 10-15 minutes, or until they are golden in colour and a toothpick inserted into the centre of a donut comes out clean. Allow them to cool for 5 minutes. While they're still warm, gently roll each donut hole into the sugar until evenly coated.

While the donuts are baking, make the cheesecake filling. Combine the cream cheese together in a small bowl with the sugar. Beat until smooth and combined. Add the strawberry jam,jelly or topping and mix through slowly until creating an almost marble/swirl effect (if using jam, make sure any bigger fruit pieces are removed before using, or they will get jammed in the nozzle).

Fill a piping bag with the cheesecake filling, and using a narrow nozzle, fill each donut with the strawberry cheesecake until they puff up and expand (not too much or the donuts will overflow).
