Can I use regular milk instead of buttermilk?

Yes, but you must add an acid to replicate the tenderizing power of buttermilk. Mix a half-cup of regular milk with one teaspoon of lemon juice or white vinegar and let it sit for five minutes before using. This curdled mixture mimics the acidity needed to activate the baking powder.

Can I use frozen blueberries instead of fresh?

Absolutely, and you do not need to thaw them first. Thawing causes them to release excess juice, which streaks the batter grey. Keep them in the freezer until the exact moment you fold them into the flour coat.

Why are my blueberries sinking to the bottom?

This usually happens because the batter is too thin or the berries were not coated in flour. Tossing the berries in flour gives them a rough surface that grips the thick cake batter. Additionally, make sure your butter is creamed correctly so the batter retains its thick structure.

How do I make a breakfast cake?

A breakfast cake is made by creaming butter and sugar, emulsifying with eggs, and folding in flour alternately with a tenderizing dairy liquid like buttermilk. The key difference from a standard dessert cake is its lower sugar content and a rustic, crisp top crust. This creates a pastry that is light enough for the morning hours.

Can I make this cake in advance or freeze it?

Yes, you can mix the batter, spread it into the pan, and refrigerate it overnight. In the morning, let it sit on the counter for thirty minutes, top with sugar, and bake. You can also freeze the baked, cooled cake wrapped in plastic for up to three months.

Can I double the recipe for a larger pan?

To double this recipe, double all ingredient weights and bake in a standard nine-by-thirteen-inch pan. Keep the oven temperature at 350ºF but begin checking for doneness at thirty-five minutes. The thicker volume may require a slightly longer total bake time.

How do I know when the cake is fully baked?

Look for a deep golden crust that springs back slightly when lightly pressed in the center. A toothpick inserted into the middle should come out clean or with a few moist crumbs, but no wet batter. If you see wet batter, return the pan to the oven for five more minutes.

What is the best way to store blueberry breakfast cake?

Store the cooled cake at room temperature in an airtight container for up to twenty-four hours to preserve the crisp sugar top. If you need to keep it longer, wrap it tightly and store it in the refrigerator for up to three days. Warm it slightly in a toaster oven before serving to restore its soft texture.

Instructions

Cream butter and sugar. Fit your stand mixer with a paddle attachment and beat the butter, lemon zest, and all but one tablespoon of sugar until the mixture is pale and light, approximately five minutes.
Incorporate wet ingredients. Add the room-temperature egg and vanilla extract, beating on medium-low until the batter is uniform and glossy.
Prepare dry ingredients. Whisk together the flour, salt, and baking powder, then toss a quarter-cup of this mixture with the blueberries in a separate bowl to prevent sinking.
Combine the batter. Alternately fold in half the dry ingredients, the buttermilk, and the remaining flour until just combined, then gently fold in the floured blueberries.
Top and bake. Scrape the batter into a parchment-lined eight-inch square pan, sprinkle with the reserved tablespoon of sugar, and bake at 350ºF for forty to forty-five minutes until golden.
Cool the cake. Allow the cake to set in the pan for fifteen minutes before lifting it out to finish cooling on a wire rack to ensure clean slices.

Notes

Always measure your flour using a digital scale to prevent the cake from becoming dense or dry.
Use room-temperature dairy and eggs to ensure a stable emulsion and a perfectly consistent cake texture.
Tossing blueberries in a small amount of flour before adding them to the batter keeps the fruit evenly distributed.
Wait the full fifteen minutes before slicing to allow the crumb structure to set properly.
