Preparation
- Preheat the oven to 175°C. Lightly grease three 20-cm round cake pans, then line them with parchment paper.
- In a mixer bowl, combine melted coconut oil, Greek yogurt, eggs, granulated sugar, brown sugar, vanilla extract, buttermilk, lemon juice, and zest. Beat until smooth.
- Gradually incorporate all-purpose flour, baking powder, baking soda, and kosher salt into the wet mixture. Mix until just combined.
- Toss blueberries in 8 g of flour to prevent them from sinking. Gently fold these into the batter along with blueberry jam for swirls.
- Divide the batter among the prepared pans. Bake for 30–35 minutes or until tops spring back when touched. Cool for 5 minutes before transferring to wire racks.
- In a clean mixer bowl, beat together salted butter, mascarpone, and powdered sugar until fluffy. Divide the frosting, mixing blueberry jam into two bowls.
- Assemble the cake by layering with different shades of buttercream and frosting the sides for a marbled effect. Chill for about 30 minutes.

Notes
Ensure all ingredients are at room temperature for a smoother batter. Avoid overmixing to keep the cake light and fluffy.
