Step-by-Step Instructions
- Prepare Your Baking Setup:
- Preheat your oven to 350°F and prepare an 8inch cake pan with cooking spray. For easier removal line the bottom with parchment paper. This preparation ensures your cake will release perfectly after baking.
- Mix Dry Ingredients:
- Combine flour sugar salt and baking soda in a large mixing bowl and whisk thoroughly. Make sure there are no lumps in the sugar or flour as this affects the final texture. Proper mixing at this stage prevents flour pockets in your finished cake.
- Add Wet Ingredients:
- Pour in the oil water lemon juice and vanilla extract and mix until just combined. Avoid overmixing which can develop too much gluten and make your cake tough. The batter should be smooth but not overworked.
- Incorporate Blueberries:
- Gently fold in the blueberries using a spatula with a light hand. Toss fresh berries in a little flour before adding to prevent them from sinking to the bottom during baking. Distribute them evenly throughout the batter for consistent flavor in every bite.
- Bake To Perfection:
- Transfer your batter to the prepared pan and bake for 35 to 40 minutes. Look for a golden top and a clean skewer when inserted in the center. Allow the cake to cool completely in the pan before attempting to remove or frost it.
- Prepare Frosting:
- Beat the softened cream cheese and butter until fluffy and light about 2 minutes. Gradually add powdered sugar continuing to beat until smooth. Adjust the consistency as needed with tiny amounts of water or additional powdered sugar.

The lemon in this recipe is truly the star ingredient. I discovered the magic of using both the juice and a bit of zest when my grandmother taught me to bake. She always said lemon desserts should wake up your taste buds with their brightness without making you pucker and this recipe achieves that perfect balance.
Storage Solutions
This blueberry lemon cake requires refrigeration due to its moisture content. Store it in an airtight container or wrapped tightly in plastic wrap where it will remain fresh for up to 5 days. The flavor actually deepens after the first day as the lemon notes mellow and infuse throughout the cake. For longer storage slice the cake and freeze individual portions wrapped in plastic and then aluminum foil for up to two months. Thaw slices in the refrigerator overnight for best texture results.
Seasonal Variations

Spring brings strawberries which work beautifully when finely diced. Winter citrus season means you can intensify the lemon flavor with additional zest or create an orange blueberry variation. Each seasonal adaptation brings new life to this versatile recipe while maintaining its foolproof nature.
