Cream butter and sugar together using the paddle attachment of an electric mixer. Then add oil and rose essence to it. In a separate mixing bowl, mix in all purpose purpose flour, custard powder, tutti frutti, baking powder, cashews if using.

Mix the powder mixture to the butter n sugar and mix it. Don't over mix in the mixer. If need be mix it again with hands. If the dough doesn't come together to make a log add a couple of tablespoons of milk and it should work.

Make the log and wrap it in the plastic serene wrap and put in the fridge for couple of hours. Once the dough is ready, you can cut them into quarter inch of slices and place them on the baking sheet and bake the cookies at 350 degrees for 12 mins or more depending on your oven.

Once the cookies are baked, pull it out of oven and let them cool down before placing them on the cooling rack. Let them cool down completely before putting them in the air tight container.

Enjoy them with a cup of tea or coffee.
