  • 2 Tbsp (2 Tbsp) AP Flour for dusting blueberries
  • 2 cups (296 g) blueberries You can use frozen but don’t thaw them

Cream Cheese Frosting

  • 16 oz (453 g) cream cheese room temperature
  • 8 oz (226 g) unsalted butter room temperature
  • 1 tsp (1 tsp) lemon extract
  • 1/2 tsp (1/2 tsp) salt
  • 32 oz (907 g) powdered sugar sifted

Instructions

  1. This is the BEST lemon blueberry cake because I use a scale so it turns out perfectly 🙂 If you convert to cups I cannot guarantee good results. Make sure all your (cold ingredients) butter, eggs, milk are at room temperature or a little warm.

Cake Instructions

  1. Heat oven to 350º F/177º C. Prepare two 8″ round cake pans with cake goop or another pan release that you prefer.
  2. Measure out buttermilk. Place 4 oz in separate measuring cup. Add the oil to the 4oz of buttermilk and set aside.
  3. To the remaining milk, add your eggs, lemon extract, lemon juice and lemon zest and gently whisk to combine. Set aside.
  4. Place the flour, sugar, baking powder, baking soda, and salt into the bowl of your stand mixer with the paddle attachment.
  5. Turn the mixer onto the slowest speed (setting 1 on Kitchen Aid mixers). Slowly add chunks of your softened butter until it is all added then let everything mix until it looks like coarse sand.
  6. Add your milk/oil mixture all at once to the dry ingredients and mix on medium (speed 4 on kitchenaid) for 2 full minutes to develop the structure. Don’t worry, this will not over-mix the cake.
  7. Scrape the bowl. This is an important step. If you skip it, you will have hard lumps of flour and unmixed ingredients in your batter. If you do it later, they will not mix in fully.
  8. Slowly add in the rest of your liquid ingredients in 3 parts, stopping to scrape the bowl one more time halfway through. Your batter should be thick and not too runny.
  9. Fill your pans 1/2 full with cake batter. Give the pan a little tap on each side to level out the batter and get rid of any air bubbles.
  10. Wash your berries (if they are fresh) and toss in flour. If berries are frozen skip washing and just toss in flour. Sprinkle half the blueberries on top of your batter. Do not stir them in.
  11. Bake for 15-20 minutes then sprinkle in the second half of your blueberries on top of the cake.
  12. Bake for another 10-15 minutes then check for doneness. If the cakes are still really jiggly, I add another 5 minutes. I check every 3 minutes after that until I’m close and then it’s every 1 min. Cakes are done when a toothpick inserted in the center comes out with a few crumbs.
  13. Remove cakes from the oven and give them a tap on the countertop to release air and prevent too much shrinking. Let them cool on a cooling rack until they are barely warm.
  14. After cooling, place the cooling rack on top of the cake, placing one hand on top of the cooling rack and one hand under the pan and flip the pan and the cooling rack over so the pan is now upside down on the cooling rack. Remove the pan carefully. Repeat with the other pan.
  15. After the cakes are fully cooled, carefully wrap them in plastic wrap and place them into the freezer or fridge for about 30 minutes to firm up the cakes and make them easier to handle for stacking.
  16. After your cakes are chilled, fill them with your cream cheese frosting and frost the outside. I finished my cake with some more fresh blueberries and organic pansies (edible).

Cream Cheese Frosting Instructions

  1. Place softened butter in the bowl of your stand mixer with paddle attachment and cream on low until smooth
  2. Place softened cream cheese in the bowl with butter in small chunks and cream on low until smooth and combined
  3. Add in sifted powdered sugar one cup at a time until combined
  4. Add your extract and salt and combine until smooth. Don’t over-mix or your frosting could separate
