Ingredients

Baking spray with flour (to ensure a clean release from the pan)
2 cups fresh or frozen blueberries (thawed if frozen)
1 tablespoon all-purpose flour (to coat the berries)
2 3/4 cups all-purpose flour (for the batter)
1 teaspoon baking powder
1/2 teaspoon baking soda
1 teaspoon kosher salt
3/4 cup salted or unsalted butter (room temperature)
2 cups granulated sugar
4 large eggs (room temperature)
2 teaspoons real vanilla extract
1/4 cup vegetable oil
1 cup full-fat sour cream (room temperature)
1 cup powdered sugar (for the glaze)
3-5 teaspoons whole milk (for the glaze)

Step-by-Step Instructions

Prepare the Oven and Pan: Preheat your oven to 350°F. Generously spray a 10-inch bundt pan with baking spray that contains flour.
Coat the Blueberries: In a small bowl, toss the blueberries with 1 tablespoon of flour until they are evenly coated. This step is crucial to prevent the berries from sinking to the bottom of the cake during baking.
Whisk Dry Ingredients: In a large mixing bowl, whisk together the 2 3/4 cups of flour, baking powder, baking soda, and salt. Set this aside.
Cream Butter and Sugar: In a separate large bowl or stand mixer, beat the room temperature butter and granulated sugar for 4-5 minutes until the mixture is light and fluffy.
Add Eggs and Vanilla: Mix in the eggs one at a time, ensuring each egg is fully incorporated before adding the next. Stir in the vanilla extract.
Incorporate Oil: Add the vegetable oil to the mixture and beat until well combined.
Combine Batter: Gradually add the dry ingredients to the wet ingredients, alternating with the sour cream. Mix in small amounts at a time to keep the batter smooth and avoid over-mixing.
Fold in Berries: Gently fold the flour-coated blueberries into the batter using a spatula to avoid breaking the fruit.
Bake: Pour the batter into the prepared bundt pan and spread it evenly. Bake for 50-65 minutes. If the top begins to brown too quickly, loosely cover it with aluminum foil for the final 20 minutes.
Cool and Release: Remove the cake from the oven and let it cool in the pan for 10-15 minutes. Carefully turn the cake onto a wire cooling rack to cool completely.
Glaze: In a small bowl, whisk together the powdered sugar and milk until you reach your desired consistency. Drizzle the glaze over the fully cooled cake.

Expert Tips / Pro Tips

Temperature Matters: Always use room temperature eggs, butter, and sour cream. This helps the ingredients emulsify properly, resulting in a smoother batter and a better rise.

Pan Preparation: Even if your bundt pan is non-stick, always use a baking spray that contains flour or grease the pan with shortening and dust it with flour. This is the best way to prevent the cake from sticking to the intricate designs of the pan.

The Foil Trick: To prevent the top of the cake from becoming too dry or dark, cover it with a piece of aluminum foil for the last 20 minutes of baking.

The Knife Test: To check for doneness, insert a butter knife into the thickest part of the cake. If it comes out clean without any sticky batter, the cake is finished.

Variations & Substitutions

Frozen vs. Fresh Berries: You can use either. If using frozen, allow them to come to room temperature and drain any excess liquid before tossing them in flour.

Butter Options: While the recipe calls for salted butter for extra flavor, you can easily substitute it with unsalted sweet cream butter if you are monitoring your sodium intake.

Mini Bundt Cakes: This recipe can be baked in mini bundt pans for individual servings. This often makes it easier to ensure the centers are fully cooked, though you will need to reduce the baking time significantly.

Serving Suggestions

This Blueberry Breakfast Bundt Cake is best served in thick slices alongside a hot cup of coffee or tea. It makes a beautiful centerpiece for a breakfast buffet. For an extra touch of indulgence, you can serve it with a side of fresh whipped cream or a scoop of lemon curd to complement the blueberry flavors.

Storage, Freezing & Reheating

Storage: Store the cake in an airtight container at room temperature for up to two days. For longer storage, keep it in the refrigerator for up to five days.

Freezing: You can freeze this cake (without the glaze for best results) by wrapping it tightly in plastic wrap and then aluminum foil. It will stay fresh in the freezer for up to three months. Thaw at room temperature before serving.

Reheating: If you prefer a warm slice, place a piece of cake in the microwave for 10-15 seconds. This will soften the butter and sour cream, making the cake taste freshly baked.

FAQ

What is a bundt cake?

A bundt cake is a round cake baked upside down in a special pan with a hole in the center. The shape allows more of the cake batter to come into contact with the edges of the pan, which helps with even heat distribution in dense cakes.

How do I remove the cake from a bundt pan without it breaking?

The best method is to let the cake cool for exactly 10-15 minutes. If it is too hot, it may crumble; if it is too cold, the sugar may cause it to stick. You can use a plastic toddler spoon to gently loosen the edges before flipping it onto a platter.

What makes this blueberry bundt cake so moist?

The combination of full-fat sour cream, butter, and vegetable oil provides a multi-layered moisture profile. The acidity in the sour cream also helps tenderize the gluten, resulting in a softer crumb.

Can I make this cake ahead of time?

Yes, this cake is an excellent make-ahead option. You can bake it a day in advance and store it covered. It often tastes even better the next day as the flavors have time to meld.

Why did my blueberries sink to the bottom?

Blueberries often sink because they are heavier than the batter. Tossing them in a small amount of flour before folding them into the mix helps them “grip” the batter and stay suspended throughout the cake.
