Detailed Instructions: How to Make the Perfect Lemon Blueberry Cake

Step 1: Gather and Prepare Your Ingredients

Having everything measured and ready before you start baking—known as mise en place—is crucial. This will ensure a smooth process and consistent results.

Ingredients you will need:

• For the cake batter:

  • 2 ½ cups all-purpose flour

  • 2 ½ teaspoons baking powder

  • ½ teaspoon baking soda

  • ½ teaspoon salt

  • 1 cup unsalted butter, softened

  • 1 ¾ cups granulated sugar

  • 4 large eggs, at room temperature

  • Zest of 2 large lemons (about 2 tablespoons)

  • ½ cup fresh lemon juice (from about 2 lemons)

  • 1 teaspoon pure vanilla extract

  • 1 cup buttermilk, at room temperature

  • 1 ½ to 2 cups fresh blueberries (washed and dried)

• For the lemon glaze or frosting (optional):

  • Powdered sugar

  • Lemon juice

  • Cream cheese or buttercream for frosting (if preferred)

Step 2: Prepare Your Baking Equipment

• Preheat your oven to 350°F (175°C).

• Grease and flour two 8-inch round cake pans or line with parchment paper.

• Use a stand mixer or hand mixer for creaming butter and sugar.

• Have a spatula, mixing bowls, and measuring cups/spoons ready.

Step 3: Mix Dry Ingredients

• In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.

• Sifting or whisking these dry ingredients aerates the flour and ensures even distribution of the leavening agents.

• Set aside.

Step 4: Cream Butter and Sugar

• In a large mixing bowl, beat the softened butter and granulated sugar on medium speed until light and fluffy—this usually takes 3 to 5 minutes.

• This process incorporates air into the batter, helping the cake rise and giving it a tender crumb.

• Scrape down the sides of the bowl as needed to ensure even mixing.

Step 5: Add Eggs and Flavorings

• Add eggs one at a time, beating well after each addition.

• Incorporate the lemon zest and vanilla extract.

• Adding eggs gradually helps to maintain an emulsion and prevents the batter from curdling.

• The lemon zest will infuse the cake with bright citrus aroma and flavor.

Step 6: Alternate Adding Dry Ingredients and Buttermilk

• Reduce the mixer speed to low.

• Add the dry ingredients in three additions, alternating with the buttermilk in two additions: dry ingredients, buttermilk, dry ingredients, buttermilk, then remaining dry ingredients.

• Begin and end with the dry ingredients.

• Mix just until combined after each addition—avoid overmixing, which can make the cake dense.

• The acidity in the buttermilk reacts with the baking soda, helping the cake rise and stay moist.

Step 7: Fold in the Blueberries

• Gently fold the fresh blueberries into the batter using a spatula.

• Be careful not to overmix or break the berries, as this can cause the batter to turn purple or blue.

• To prevent the berries from sinking to the bottom during baking, toss them in a tablespoon of flour before folding into the batter.

• This coats the blueberries and helps them stay suspended evenly in the cake.

Step 8: Divide Batter and Bake

• Evenly divide the batter between the prepared cake pans, smoothing the tops with a spatula.

• Tap the pans gently on the counter to release any large air bubbles.

• Bake in the preheated oven for 30–35 minutes or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

• Oven temperatures vary, so begin checking around 28 minutes.

Step 9: Cool the Cakes

• Remove the pans from the oven and place them on a wire rack.

• Let the cakes cool in the pans for about 10–15 minutes.

• Then carefully run a knife around the edges to loosen and invert them onto the wire rack to cool completely.

• Cooling the cakes completely before frosting prevents the frosting from melting.

Step 10: Prepare the Lemon Glaze or Frosting (Optional)

• For a simple glaze, whisk powdered sugar with fresh lemon juice until smooth and pourable.

• For frosting, a cream cheese or buttercream lemon frosting complements this cake beautifully.

• Beat cream cheese or butter with powdered sugar and add lemon juice and zest for flavor.

• Adjust consistency with milk or more sugar as needed.

Step 11: Assemble the Cake

• If desired, level the cake layers by slicing off the domed tops for a flat surface.

• Spread a layer of frosting or glaze on top of the first layer.

• Place the second cake layer on top and finish frosting the top and sides.

• For the glaze, drizzle it over the top, allowing some to drip down the sides.

Step 12: Garnish and Serve

• Garnish the cake with fresh blueberries, lemon zest curls, or edible flowers for a beautiful presentation.

• Let the cake chill slightly to set the frosting if needed.

• Slice and serve with a cup of tea, coffee, or a light dessert wine.

Additional Tips for Success:

• Use room temperature ingredients: This helps everything combine smoothly.

• Fresh lemons and berries: Make a big flavor difference compared to bottled juice or frozen fruit.

• Avoid overmixing: To keep your cake tender and airy.

• Watch baking time: Ovens vary, so check doneness early.
