Step 1: Prep the Ingredients

1. Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
2. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. Cut cream cheese into ¼-inch pieces and freeze for at least 1 hour until solid.

Step 2: Make the Cookie Dough

4. In a large mixing bowl, beat butter and sugar with an electric mixer for about 2 minutes, until light and fluffy.
5. Add egg, vanilla extract, and almond extract. Mix until well combined.
6. Gradually mix in ⅓ of the flour mixture, then add ½ of the sour cream. Repeat, alternating between flour and sour cream, until just combined. Do not overmix.

Step 3: Fold in the Add-ins

7. Gently fold in blueberries and frozen cream cheese pieces, being careful not to crush the berries.

Step 4: Shape & Bake the Cookies

8. Drop 1 ½ tablespoon-sized balls of dough onto the prepared baking sheets, spacing them 2 inches apart.
9. Bake for 15 to 18 minutes, or until the bottom edges are lightly golden.
10. Let the cookies cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
