Step 1

Tip: place sticks of butter in the freezer for at least 15 minutes. Then use a grater grate the butter so that it spreads easily over the top of the cake.

Step 2

Preheat oven to 350°F.

Step 3

Pour pie filling and blueberries in the bottom of a 9x13-inch pan. Top with powdered cake mix.

Step 4

Grate the frozen butter evenly over the top of the cake mix. (Grating the butter gives easier and better coverage.)

Step 5

Bake for 45-50 minutes. Serve warm or room temperature with ice cream. Store in refrigerator for up to 3 days.

Step 6

Note: check the cobbler halfway through baking. If there are any sections of cake that are still powdery after all the butter is melted, add a bit more butter or spray these areas with nonstick cooking spray.
