🔪 How to Make Lemon Blueberry Cake

Making this cake is simple and straightforward. Follow the directions below and you will have a delicious cake in no time at all.

Step 1: Preheat the oven

Preheat your oven to 350 degrees. 

Step 2: Prepare your cake pans

Spray two 8-inch round cake pans with nonstick spray and set aside.

Step 3: Mix together the cake mix and ingredients on the box 

In a large bowl, whisk together the cake mix plus ingredients on the back of the box. 

Step 4: Add in lemon and mix well

Add in lemon zest and the juice of 1 lemon, and mix well. 

Step 5: Toss blueberries in flour

In a separate bowl, add the flour, and toss the blueberries into the flour. This can help keep the blueberries from sinking. 

Step 6: Shake off the extra flour

Shake off the excess flour and add the blueberries to the cake mix, and gently fold them in. 

Step 7: Pour the batter into the cake pans

Pour batter evenly between the cake pans.

Step 8: Bake according to the directions on the box

Bake at 350 according to the time on the box, but also adding 2-3 extra minutes since we added the blueberries. A toothpick inserted in the center should come out clean (minus blueberry) when the cake is finished baking. 

Step 9: Cool the cake

Allow the cake to cool completely before frosting.

Step 10: Cream together butter and powdered sugar 

To make the frosting, in a large bowl use a hand mixer to mix together softened butter and powdered sugar until well incorporated. 

Step 11: Add in vanilla, milk, and lemon juice

Add vanilla, milk, and 1 tbsp. lemon juice, mix well until frosting forms and is well combined.  If the frosting is too thick, add milk, 1 tbsp. at a time, until it reaches the desired consistency. 

Step 12: Frost the cake

Frost the bottom layer of your cake, set the top layer on, and frost again, then top with fresh lemon slices and fresh blueberries.

💭 Tips

Here are a few tips to help you make this recipe perfectly:

  • Be sure to zest your lemon before juicing it. It is much easier to zest a lemon before you cut into it.
  • If you are using frozen blueberries, make sure to allow them to thaw and dry before you add them to the cake batter.
  • Do not overmix the cake batter. Mix it just until everything is combined.
  • Do not open the oven door while the cake is baking. Every time you open the door, heat escapes and can cause your cake to become overcooked or uneven.
  • For best results, use fresh berries that are in season.
  • Frozen berries can also be used, but they may cause the cake to be a little more moist.
  • To get perfectly smooth frosting, make sure all of your ingredients are at room temperature before you start mixing them together.
