A secret cookie box that can hide love notes

Prepare the ingredients.

Soften the butter at room temperature and beat until smooth, then add the powdered sugar and salt and mix until pale and fluffy. Gradually add the eggs, beating until evenly combined.

Sift in the cake flour and red velvet powder and mix until a dough forms.

Place it on wax paper and wrap it up, roll it flat, then put it in the refrigerator to freeze for thirty minutes. Take it out and roll it thin again.

Use a large heart-shaped mold to first carve out the heart shape, then use a small heart-shaped mold to carve out a hollow shape within the large heart. Preheat the oven to 160 degrees and bake for 10-15 minutes.

Make meringue: Pour egg whites and powdered sugar into a bowl, add lemon juice, and mix until whipped into meringue.

After taking the cookies out, let them cool, and use meringue to draw the patterns you want.

Then stick it together with the unpainted cookie, add the note and decorative sugar, and then stick the painted cookie together.
