Preheat the oven at 180 degree C. Grease the loaf tin. If you are using a silicon or non stick tin then there is no need to grease.

We need to wrap the blueberries in flour so that they don't settle at the bottom of the cake while baking. Take some flour (around 1/8 cup) from the 1.5 cup of flour and toss the blueberries in it.

In another bowl sieve all the dry ingredients - the remaining flour, baking soda, baking powder & salt. Mix in the lemon zest and set it aside.

With a electric mixer, whisk the oil and sugar. Then add curd to it. Then stir in 1 Tbsp Lemon juice & vanilla essence.

Then alternately add flour mixture and milk and fold the ingredients till everything is well. Now add blackberries to it.

Pour the batter into the tin and bake at 180 degree C for around 45 min. or until a toothpick inserted in the center of the cake comes out clean.

After 10 min, unmould and let it cool on a wire rack.

You can even add Tutti-frutti to the cake. I thought of it after tasting my cake so will do that next time I bake some.
