Why did my blueberries sink to the bottom?

Blueberries sink when the batter is too thin or when the berries are not tossed in flour before folding. The flour coating creates friction, helping the berries cling to the batter while it expands in the oven. Additionally, over-mixing can thin the batter, making it easier for heavy fruit to fall.

How do I prevent the cake from sticking to the Bundt pan?

Use a high-quality nonstick baking spray that contains flour, or brush the pan with a homemade paste of equal parts melted butter and flour. Ensure you coat every single ridge and the center tube thoroughly. Never use liquid oil or butter alone, as they can pool in the crevices and cause sticking.

Can I use frozen blueberries instead of fresh?

Yes, you can use frozen blueberries, but do not thaw them before adding to the batter. Thawing releases excess moisture that will streak your cake with blue-gray dye and make the batter soggy. Toss them in flour while frozen and fold them in quickly right before baking.

How do I make my cake extra moist?

The secret to maximum moisture lies in the dual-fat combination of butter and oil, along with the high fat content of sour cream. Sour cream adds rich moisture without thinning the batter like milk would. Be careful not to over-bake, as even a few extra minutes can dry out the crumb.

What is the best way to get a strong lemon flavor?

The strongest lemon flavor comes from the zest, not the juice. Rubbing the lemon zest directly into the granulated sugar before creaming releases the essential oils, dispersing the citrus flavor throughout the entire cake. The glaze also provides a sharp, concentrated hit of fresh acid.

Should I glaze the cake while it's warm or cool?

Always wait until the cake is completely cool before applying the glaze. If the cake is even slightly warm, the glaze will melt, turn translucent, and run off the sides into a puddle. A cool cake allows the glaze to set into a thick, beautiful white drape.

How long does this cake last, and how should it be stored?

This cake keeps beautifully at room temperature in an airtight container for up to three days. If you want to keep it longer, wrap individual slices tightly in plastic wrap and store them in the freezer for up to three months. Avoid refrigerating the cake, as the cold air will dry out the crumb.

Instructions

Prep and Coat the Fruit: Preheat oven to 350°F. Toss blueberries with 1 tablespoon of flour until fully coated. Set aside.
Whisk the Dry Foundation: In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
Cream the Fats and Sugar: Beat butter and sugar on medium-high speed for 4-5 minutes until light and fluffy.
Emulsify the Wet Ingredients: Mix in eggs one at a time, then add vanilla, lemon juice, lemon zest, and oil, mixing until combined.
Incorporate the Batter: Alternating, add dry ingredients in three parts and sour cream in two parts, mixing on low speed until just combined.
Fold in the Blueberries: Gently fold in the flour-coated blueberries using a rubber spatula until evenly distributed.
Bake the Cake: Pour batter into a well-greased 10-inch bundt pan. Bake at 350°F for 50-65 minutes until a toothpick inserted comes out clean.
Cool and Invert: Cool in the pan on a wire rack for 30 minutes, then invert onto the rack to cool completely.
Glaze and Set: Whisk confectioners’ sugar and lemon juice until smooth. Drizzle over the cooled cake and let sit for 15 minutes to harden.

Notes

Room Temperature is Key: Cold eggs or sour cream will split the butter emulsion, resulting in a dense, heavy cake.
Measure by Weight: Use a kitchen scale for flour to guarantee a soft, tender crumb instead of a dry, floury texture.
Prevent Sticking: Use a baking spray containing flour and coat every single crevice of the bundt pan thoroughly.
Do Not Thaw Frozen Berries: If using frozen berries, fold them in while completely frozen to prevent bleeding color into the batter.
