With just a few extra ingredients, you can turn an ordinary cake mix into a memorable dessert. In this recipe, a yellow cake mix is combined with sour cream, lemon juice, and blueberries to make a picture-perfect Bundt cake that is moist and delicious. The blueberries give the cake excellent flavor and leave beautiful purple polka dots throughout the cake. 

The cake has plenty of flavor on its own, but feel free to use a lemon cake mix for more lemon flavor. You can also add a sweet lemon glaze and decorate with additional fresh blueberries if desired.

Tips

  • If you toss the berries in a small amount of flour before folding them into the batter, they are less likely to sink.
  • If you're using frozen berries, do not defrost them. Toss with a small amount of flour before folding them into the batter.
  • The key to success when using a Bundt pan is to thoroughly grease every crevice of the pan, making sure not to leave pools or chunks of butter behind. Completely cover with flour and tap out excess before adding the batter.
  • If you don't have a Bundt pan, feel free to make this cake in another size pan. Follow our tips for baking times for different-size cake pans.

How to Store

  • Because the cake has fruit in it, it's best to store it in the refrigerator if not eating right away. Cover the cake with plastic wrap before refrigerating.
  • For long-term storage, wrap the cake well and place it in the freezer. You can also slice it and wrap it in individual slices for up to one month.

Recipe Variations

  • Swap the yellow cake mix for vanilla, French vanilla, or lemon cake mix. Just make sure to use the "pudding in the mix" variety.
  • Fresh, firm raspberries or blackberries can be used in place of the blueberries. Fold them into the batter carefully to keep them from breaking apart too much.
