Mixed Berry Bundt Cake with Lemon Glaze - this cake is made with 3 types of berries all combined in one beautiful cake: blueberries, raspberries, and blackberries. Delicious Summer cake that can be made with either buttermilk, or Greek yogurt, or Kefir. This recipe uses 10-cup bundt pan.
Now we’ll be adding flour mixture into the butter-sugar mixture in 3 gradual steps, instead of dumping all of flour at one time. If you dump all of flour mixture into your butter mixture at one time, it will be more difficult to stir and you won’t get a smooth texture. So, we’ll be adding flour and Greek yogurt (or buttermilk) in 3 additions:
With your mixer on low speed, add 1/3 of flour mixture to butter-sugar mixture, beating just a little until all is well combined. Then follow by 1/4 cup of Greek yogurt (or buttermilk). Add second 1/3 cup of flour mixture, beating with mixer just to combine. Follow by 1/4 cup of Greek yogurt (or buttermilk), beating just to combine. Finally, add third 1/3 cup of flour mixture, followed by final 1/4 cup of Greek yogurt (or buttermilk). Again, beat just enough to combine.
Note about using frozen berries: I did make this cake with frozen berries without defrosting them. It's important that, if using frozen berries, they should not be clumped together, each berry should be separate (I freeze fresh berries by lining them on a cookie sheet). So you can use both fresh and frozen berries, and in either case you toss them with flour before adding to the batter.
