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 Kefir. This recipe uses 10-cup bundt pan.
I discovered this triple berry buttermilk bundt cake recipe on one of my most favorite food blogs, Smitten Kitchen. When Deb published that blog post, I found myself coming back to her site even more often, just to look at her pictures of this mixed berry bundt cake full of blackberries, blueberries, and raspberries, and not being able to easily forget it. Deb’s pictures made it look so enticing that I made this cake 3 times in the last 3 months.
And the only reason I didn’t make it even more often is that there is only so much cake that one family can eat! Each time it was with different friends, and each time it was a huge success! The only change that I made to the recipe was to use kefir instead of buttermilk. I love kefir, it’s something I grew up drinking, so I try to use it in my recipes. Kefir and buttermilk are good substitutes for each other, so using either one will work in this recipe. This triple berry bundt cake also makes a beautiful presentation and is VERY easy to make.
While this mixed berry cake is perfect when made with fresh berries in the summer time, I’ve made it both with fresh and frozen berries (without defrosting them). And by frozen berries I mean fresh berries that I froze myself, so that each berry remained separate and not clumped together. So, this recipe will work great both with fresh berries and frozen berries (as long as they are separated and not clumped). More on that – below under recipe instructions. This makes me very happy, because it means that I can enjoy this mixed berry bundt cake BOTH in the summer AND in the winter.
Ever since I made this cake, I’ve been on a bundt cake obsession and made quite a few more bundt cakes (apple cinnamon, chocolate, etc.).
This is what the cake batter looks like:
Mixing berries with flour (this helps so that they don’t sink to the bottom and don’t clump together):
Fold in the berries into the cake batter:
Add mixed berry cake batter to the bundt pan:
Triple berry bundt cake is baked and successfully released out of the bundt pan! Yes! See the tips on how to successfully release the cake from the bundt pan below, in the recipe box.
Add lemon glaze and you’re done! And you don’t even need the lemon glaze. This cake is good as is!
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 Kefir. This recipe uses 10-cup bundt pan.
- 2 1/2 cups all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon salt
- 1 cup unsalted butter (room temperature)
- 1 3/4 cups granulated sugar
- zest of 1 lemon
- 3 large eggs
- 1/2 teaspoon vanilla extract
- 3/4 cup kefir (or buttermilk)
- 3 cups mixed berries (I used 1 cup raspberry, 1 cup blackberry, 1 cup blueberry)
- 2 tablespoons all-purpose flour
- 1 cup powdered sugar
- 2 tablespoons powdered sugar
- 4 tablespoons lemon juice (freshly squeezed)
- 1 tablespoon unsalted butter (softened, not melted! the butter should still be able to retain its shape!)
- Preheat oven to 350 F. Use 10-cup bundt pan.
- In a medium bowl, mix 2 1/2 cups flour, baking powder and salt and combine thoroughly.
- In a separate large bowl, add together the softened butter, sugar and lemon zest and mix, using mixer, on high setting for about 5 minutes until even consistency is reached and the mixture reaches lighter color.
- Add eggs, vanilla to the butter-sugar mixture and continue beating until well-incorporated.
- 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 kefir (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 kefir (or buttermilk). Add second 1/3 cup of flour mixture, beating with mixer just to combine. Follow by 1/4 cup of kefir (or buttermilk), beating just to combine. Finally, add third 1/3 cup of flour mixture, followed by final 1/4 cup of kefir (or buttermilk). Again, beat just enough to combine.
- Make sure to have your mixer on low speed while adding flour, otherwise flour might fly around your kitchen. Make sure to not overmix or overbeat, use mixer just to combine the ingredients.
- In a separate bowl, combine berries with 2 tbsp of flour. This is supposed to prevent berries from clumping together and sinking.
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.
- Using spatula, fold berries into the cake batter, trying not to squish the berries.
- Use 10 cup bundt pan. Spray your cake pan with a Baking Spray with Flour (which works great for bundt pans). Pour batter gently into prepared pan.
- Bake for at least 60 minutes (depending on the oven, it could be as long as 1 hour 15 minutes), until the toothpick inserted into the center comes out clean. Mid-time through the baking, turn the pan around in the oven for even baking.
- Remove the pan from oven, let it cool for 40 minutes on wire rack.
- After your bundt pan cooled off for 40 minutes, place the bundt pan in the freezer for 30 minutes - it will still be quite hot to the touch (even after 40 minutes of cooling), so use kitchen gloves to handle the pan.
- Remove the pan from the freezer after 30 minutes, invert the bundt pan and let it sit inverted for a bit to let the gravity do the work (it could take as little as half a minute or as long as 20 minutes, depending on your bundt pan). Then, gently lift bundt pan and your cake should be released.
- Whisk powdered sugar, lemon juice and butter until very thick and very white. Spread this lemon juice frosting over the top of the cooled cake like shown on the photos.
