Rainbow Heart Cookie

In the room-temperature unsalted butter for Rainbow Heart Cookies, gradually add powdered sugar, vanilla extract, salt, and egg yolk, and mix well.

Sift in the cake flour and mix well.

After mixing thoroughly, it appears in large granular form.

Transfer to the cutting board and knead into a ball.

Divide the dough into three portions first.

Take one portion, put it in a resealable bag, and place it in the refrigerator. Divide the remaining two-thirds into six portions (six colors).

Add the coloring separately and knead evenly, then wrap it in a plastic bag.

This is the key to successfully making a beautiful rainbow heart! The height of the rainbow heart is designed to be 3cm, with each layer being 5mm. At the same time, measure the thickness of the heart-shaped mold, which is 2cm here.

Find two magazines about 5mm thick, place them on both sides of the colored dough, cover the colored dough with plastic wrap, and roll it into rectangular thin sheets along the thickness of the magazines. Repeat six times to process all the colored dough.

Mix egg white and water to make an egg white water adhesive, and brush a small amount onto the colored dough.

Stick them in order by red, orange, yellow, green, blue, and purple.

Cover with plastic wrap and gently press down with a rolling pin, then freeze in the refrigerator.

Mark the thickness of the mold with a ruler; here it is.

Lay the rainbow blocks flat and press them into a heart shape.

Brush egg white water between each piece of rainbow heart as well.

Stick them all together, and gently press each one down as you attach it.

Freeze for 2 hours.

Roll the primary-colored dough into small strips and fill them into the gaps of the heart shape.

After covering the outer layer of the heart shape, cover it with another layer.

Brush a layer of egg white water on the surface of the wrapped cookie dough.

Roll it on the colorful sugar beans so that they stick evenly, then freeze until hard.

Cut it into slices of moderate thickness.

Bake at 10-11 degrees Celsius until the surface is lightly golden.

Then, quickly take it out to show off!!!! Or chase your goddess/god~ Everyone will definitely say woooooow!! You made this?! No way!? Can you really eat it!? How did you make it!?
