Get your oven nice and warm at 350°F (175°C). Line a cookie sheet with parchment paper to prevent sticking.
02 -
Beat the softened butter, cream cheese, and sugar together until it's light and fluffy - about 3 minutes. You want it to look whipped and creamy.
03 -
Mix in the egg and vanilla until everything's smooth and well combined.
04 -
Whisk flour, baking powder, and salt in a separate bowl. Gradually stir this into your wet mixture until just combined - don't overmix!
05 -
Gently fold in your blueberries and white chocolate chips. Be gentle here - you don't want crushed berries!
06 -
Drop spoonfuls of dough onto your lined baking sheet, leaving about 2 inches of space between each cookie.
07 -
Bake for 10-12 minutes until the edges are just turning golden but the centers still look soft.
08 -
Let them cool for a few minutes on the baking sheet, then move to a wire rack. Once completely cool, dust with powdered sugar if you like.
