Mix Ingredient A until well combined. You can use a whisk or a mixer on low speed, just until blended.

Add Ingredient B to Ingredient A, mix with a spatula until it can be formed into a dough. If you don't use all the dough in one day, you can store it in an airtight container in the fridge. When you want to use it the next day, let it come to room temperature before using.

Palm Cheese Cookies: Take 5 grams of dough using a measuring spoon, roll it into a ball with your hands, then roll it in palm sugar until fully coated. Arrange on a baking sheet. Bake for 20 minutes on the lower rack, then move to the middle rack for another 20 minutes (40 minutes total). Remove from the oven, let cool to room temperature, then transfer cookies to an airtight container.

Thumbprint Cookies: Take 5 grams of dough using a measuring spoon, dip it in egg white, then roll it in grated cheese until fully covered.

Arrange on a baking sheet, press with your finger to make an indentation (I made a heart shape), and pipe blueberry jam into the indentation. Bake for 10 minutes on the lower rack, then move to the middle rack for another 20 minutes (30 minutes total). Remove from the oven, let cool to room temperature, then transfer cookies to an airtight container.

Snow White Pandan Cookies: Add a few drops of pandan food coloring to the dough, mix well. Take 5 grams of dough, roll into a ball, and arrange on a baking sheet. Bake for 20 minutes on the lower rack, then move to the middle rack for another 20 minutes (40 minutes total). Remove from the oven, let cool to room temperature, then roll in powdered sugar until fully coated, and transfer cookies to an airtight container.

Cornflake Cookies: Crush cornflakes until fine, divide into two parts. Mix one part into the dough. Take 5 grams of dough, roll into a ball and flatten with your hands.

Dip in egg white, then roll in the remaining crushed cornflakes until fully coated. Arrange on a baking sheet. Bake for 20 minutes on the lower rack, then move to the middle rack for another 20 minutes (30 minutes total). Remove from the oven, let cool to room temperature, then transfer cookies to an airtight container.

How many jars does one recipe make? This recipe is divided into four types of cookies. For palm cheese, snow white pandan, and thumbprint cookies, you won't get a full jar. The cornflake cookies yield more than a jar because the added cornflakes increase the dough volume.
