Triple Berry Summer Buttermilk Bundt Cake

The memory of my grandmother’s summer kitchen is forever intertwined with the scent of berries baking. She’d have us grandkids out picking wild blackberries and raspberries from the tangled patches behind her house, our fingers stained purple and red. The real reward, of course, wasn’t just the sticky-sweet taste of the berries themselves, but the promise of the magnificent cake that would emerge from her ancient oven later that afternoon – a simple, golden bundt, bursting with those very berries, and smelling faintly of lemon. This Triple Berry Summer Buttermilk Bundt Cake is my attempt to recapture that simple joy, that perfect taste of summer, and to share it with you.

• Cook Time: 55-60 minutes
• Total Time: 1 hour 15 minutes – 1 hour 20 minutes
• Servings: 12
• Yield: 1 Bundt Cake
• Dietary Type: Not specified

Ingredients

Cake:

• 2 1/2 cups all-purpose flour
• 2 teaspoons baking powder
• 1 teaspoon fine sea salt or 1 teaspoon table salt
• 1 cup unsalted butter, at room temperature
• 1 3/4 cups granulated sugar
• Zest of 1 lemon
• 3 large eggs, at room temperature
• 1/2 teaspoon vanilla extract
• 3/4 cup buttermilk
• 2 tablespoons all-purpose flour
• 3 cups berries (blueberries, raspberries, blackberries, etc) – Use fresh or frozen, and feel free to mix and match your favorites!

Glaze:

• 2 cups powdered sugar
• Juice of 1 lemon
• 1 tablespoon unsalted butter, very, very soft

Equipment Needed

• 10-cup Bundt pan
• Medium bowl
• Whisk or sifter
• Stand mixer or large mixing bowl
• Silicon spatula
• Wire rack

Instructions

1. Preheat your oven to 350°F (175°C). Generously grease a 10-cup Bundt pan, either with butter or a nonstick spray. Set aside. If you have a regular Bundt pan that is not non-stick, you’ll want to ensure every nook and cranny is coated with butter or even shortening (the solidity of both helps them stick to the cake walls), and then dust the inside with flour. Setting your cake pan in the fridge or freezer (to set the coating even further) while you make the cake batter will provide even more insurance.
2. In a medium bowl, whisk or sift 2 1/2 cups flour, 2 teaspoons baking powder and 1 teaspoon salt together and set aside.
3. In the bowl of a stand mixer or large mixing bowl, cream together 1 cup butter, 1 3/4 cups sugar and the zest of 1 lemon until light and impossibly fluffy, about 3 to 5 minutes.
4. Then, with the mixer on a low speed, add your 3 eggs one at a time, scraping down the bowl between each addition. Beat in 1/2 teaspoon vanilla extract, briefly.
5. Add 1/3 of the flour mixture to batter, beating until just combined, followed by half the 3/4 cup buttermilk, another 1/3 of the flour mixture, the remaining buttermilk and remaining flour mixture. Scrape down from time to time and don’t mix any more than you need to. Overmixing will develop the gluten in the flour, resulting in a tougher cake.
6. In the bowl where you’d mixed your dry ingredients, toss the 3 cups berries with the 2 tablespoons of flour. This helps prevent the berries from sinking to the bottom of the cake during baking.
7. With a silicon spatula, gently fold the berries into the cake batter. The batter will be very thick and this will seem impossible without squishing the berries a little, but just do your best and remember that squished berries do indeed make for a pretty batter.
8. Spread cake batter — you might find it easier to plop it in the pan in large spoonfuls, because it’s so thick — in the prepared baking pan and spread the top smooth.
9. Bake for 55 to 60 minutes, rotating the cake 180 degrees after 30 minutes (to make sure it browns evenly). The cake is done as soon as a tester comes out clean of batter.
10. Set cake pan on a wire rack to cool for 30 minutes, before inverting the cake onto a serving platter to cool the rest of the way. Cool completely.
11. Once cool, whisk together the 2 cups powdered sugar, juice of 1 lemon and 1 tablespoon butter until smooth and very, very thick. (If you’d like it thinner, add more juice, but I like the thick drippiness of it, seen above.)
12. Spread glaze carefully over top of cake, letting it trickle down the sides when and where it wishes.
13. Serve at once or keep it covered at room temperature for 3 to 4 days.

Expert Tips & Tricks

• Room Temperature Matters: Using room temperature butter and eggs is crucial for achieving a smooth and emulsified batter. Cold ingredients can seize up the butter, leading to a curdled batter. If you forget to take your eggs out of the fridge, submerge them in warm water for about 10 minutes.
• Don’t Overmix: As mentioned earlier, overmixing the batter develops the gluten in the flour, resulting in a tougher cake. Mix until just combined.
• Check for Doneness Early: Every oven is different, so start checking for doneness around 50 minutes. Insert a toothpick or cake tester into the center of the cake; if it comes out clean, it’s done.
• Cooling is Key: Resist the urge to unmold the cake immediately after baking. Letting it cool in the pan for 30 minutes allows it to firm up, preventing it from breaking when inverted.
• Adjust the Glaze: The consistency of the glaze can be adjusted to your liking. For a thinner glaze, add more lemon juice, a teaspoon at a time. For a thicker glaze, add more powdered sugar.

Serving & Storage Suggestions

Serve this Triple Berry Summer Buttermilk Bundt Cake at room temperature. The glaze is best applied just before serving, but the cake itself can be made a day or two in advance.

To store:

• Room Temperature: Store the cake in an airtight container at room temperature for up to 3-4 days.
• Refrigerator: For longer storage (up to 1 week), store the cake in an airtight container in the refrigerator. However, the cake may become slightly drier in the fridge.
• Freezer: Wrap the cooled cake tightly in plastic wrap, then in aluminum foil, and freeze for up to 2-3 months. Thaw overnight in the refrigerator before serving.

Variations & Substitutions

• Gluten-Free: Substitute the all-purpose flour with a gluten-free blend. Make sure the blend contains xanthan gum or another binding agent.
• Dairy-Free: Replace the buttermilk with a dairy-free alternative, such as almond milk or soy milk mixed with a tablespoon of lemon juice or vinegar. Use a dairy-free butter substitute.
• Berry Variations: Get creative with your berries! Use whatever is in season or your personal favorites. Try adding other fruits like peaches or nectarines.
• Lemon Extract: For an extra burst of lemon flavor, add 1/4 teaspoon of lemon extract to the batter.
• Spice it up! Add 1/2 teaspoon of ground cinnamon or nutmeg to the flour mixture for a warm, spiced cake.

FAQs (Frequently Asked Questions)

Q: Can I use frozen berries in this recipe?
A: Yes, frozen berries work perfectly well. Just be sure to toss them with the flour before adding them to the batter to help prevent them from sinking.

Q: My cake is browning too quickly on top. What should I do?
A: Tent the cake with foil during the last 15-20 minutes of baking to prevent it from browning too much.

Q: Can I make this cake ahead of time?
A: Yes, you can bake the cake a day or two in advance and store it at room temperature in an airtight container. Glaze it just before serving.

Q: My glaze is too thick/thin. How can I adjust it?
A: Add more lemon juice, a teaspoon at a time, to thin the glaze. Add more powdered sugar, a tablespoon at a time, to thicken it.

Q: Do I have to use a Bundt pan?
A: While a Bundt pan gives the cake its classic shape, you could use a regular cake pan. Keep in mind the baking time might need adjustment. Deeper pans will need longer baking times and vice versa.
