INGREDIENTS:

CAKES:
3 cups all-purpose flour 1 tbsp baking powder 1 tsp salt
4 eggs
2 cups sugar
1 tbsp vanilla extract
¾ cup vegetable or canola oil 1¼ cup milk

LEMON CURD:
150 ml lemon juice
3 whole eggs

150 g sugar (3/4 cup) 1 pinch salt
1 cup cold butter, cubed

MASCARPONE WHIP:
2 cups whipping cream

INSTRUCTIONS

The Cake
1. Pre-heat oven to 350C. Spray and parchment line 2 eight-inch round spring-form cake pans.
2. In a bowl sift flour and baking powder. Add salt.
3. In separate bowl whisk eggs with sugar until pale yellow. Add vanilla, oil, and milk. Mix until total homogeneous.
4. Mix dry ingredients into wet until completely combined but DO NOT OVER-MIX.
5. Divide evenly between the two cake pans. Use baking scale to be exact.
6. Bake for about 40 minutes or until cake tester comes out clean. Do not open oven during the bake. You run the risk of deflating the whole thing!
7. Allow cakes to cool completely. Using a knife, cut cakes in half horizontally. Take your time. You can also freeze cakes for up to a month at this point.

The Lemon Curd
1. In a small sauce pot, over medium heat, combine lemon juice, eggs, yolk, sugar, and salt. Continue to whisk until mixture thickens and begins to create large "bull frog" bubbles. Once this happens, remove from heat and add in cubed butter, a few pieces at a time. Continue to whisk until full incorporated.
2. Pour curd onto a parchment lined baking sheet, cover in plastic wrap, and place in fridge until cooled.

The Whipping
1. Add all ingredients into mixer with whisk attachment. Mix on medium high until soft peaks form, about 3 minutes.

The Assembly
1. If you made it this far, well done. The worst is behind you! Now comes the fun part! In front of you make sure to have your 4 pieces of cake, curd, mascarpone whip, and a 1/2 pint of fresh blueberries. Starting at the bottom (obviously) lay down one layer of cake and smear the mascarpone whip over liberally. Repeat with lemon curd. Continue this for all three layers and top of cake. When you have gotten to the top add on the fresh blueberries.
