Make the Lemon Blueberry Cake Recipe for a bright, easy cake with lemon glaze and juicy blueberries. Bake and enjoy today.
Preheat the oven to 350°F (175°C). Grease and lightly flour two 9-inch round cake pans so the surfaces are ready; set them side-by-side on the painted pine wood surface while you work, lids or covers off. This is quick setup work — it keeps everything moving once the batter is ready and ensures even, identical layers from the two pans.
In a large mixing bowl, cream 1 cup softened unsalted butter with 2 cups granulated sugar until the mixture becomes pale, airy, and noticeably lighter in texture. Beat until you see tiny ribbon-like trails when the beater is lifted — that aeration is what gives the cake a tender crumb.
Add the 4 large eggs one at a time, beating each in until incorporated so the batter stays smooth and emulsified. Stir in 1 teaspoon vanilla extract at the end to lift the flavor and round out the lemon notes that will come later.
In a separate bowl, whisk together 3 cups all-purpose flour, 1 tablespoon baking powder, and 1/2 teaspoon salt until evenly combined and aerated. Breaking up lumps now prevents over-mixing later and helps maintain a light texture.
Add the dry ingredients to the butter-egg mixture in three additions, alternating with 1 cup milk — begin and end with the flour mixture. Stir gently and stop as soon as everything is just combined; a few small streaks of flour are better than an overworked batter.
Gently fold in the zest of 2 lemons and 1 cup fresh blueberries, using a spatula to lift and turn without crushing the berries — you want distinct blue bursts and bright flecks of lemon dispersed through a pale yellow, slightly glossy batter.

Evenly divide the finished batter between the two prepared 9-inch pans, smoothing the tops with an offset spatula so each layer bakes with a flat, uniform surface. Small swirls and the occasional visible blueberry are fine — they become pretty interior details after baking.
Bake the pans for 30–35 minutes until the cakes are golden at the edges and a toothpick inserted into the center comes out clean. Remove the pans from the oven and allow them to rest on the painted pine surface for about 10 minutes so the crumb firms up slightly.
Turn the cakes out onto a wire rack and let them cool completely. Cooling fully prevents the glaze from melting on contact and keeps the slices clean and well-defined when plated.
Whisk together 1 cup powdered sugar with 2 tablespoons fresh lemon juice and 1 teaspoon lemon zest until perfectly smooth and glossy. The glaze should be slightly thick but pourable — a bright, shiny finish that will cling to the cake.
Stack or plate a slice from the cooled layers and drizzle the lemon glaze over the top, letting a few glossy drips fall naturally down the sides. Serve on a decorative plate and enjoy the interplay of light, fluffy crumb, tangy lemon, and bursts of blueberry.
