With just a few extra ingredients, you can turn an ordinary cake mix into a memorable dessert. A yellow cake mix is combined with sour cream, lemon juice, and blueberries to make a picture-perfect bundt cake. The cake has plenty of flavor on its own, but you can add a sweet lemon glaze and decorate with fresh blueberries if desired.

The key to success when using a bundt pan is to thoroughly grease every crevice of the pan, not leaving pools or chunks of butter behind. Completely cover with flour and tap out all of the excess before adding the batter.

This easy blueberry cake is made with a yellow cake mix, but feel free to use a lemon cake mix for more lemon flavor. Thanks to the sour cream, oil, and eggs, this cake is moist and delicious. The blueberries give the cake excellent flavor and leaves beautiful polka dots throughout the cake.

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.

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 and toss with a small amount of flour before folding them into the batter.
