Aren't these Rainbow Sandwich Cookies lovely! I know I love the classic sugar cookie with frosting. This is the same thing, but reversed. Instead of tinting the frosting, you're tinting the cookie dough. You frost one cookie and then put another cookie on top. These cookies are making me feel excited for a new spring season.
Regular food coloring works fine, but if you happen to see gel food coloring, that will give you the more intense colors you see here. I think this looks like a fun baking project to do with your kids.
Here's the recipe and directions for making these sweet, pretty cookies. Oh yeah, and, ahem, be sure to read the whole recipe all the way through before starting.

Food coloring or food gel
1. Heat oven to 375°F. Divide dough evenly among 3 bowls (or 1 for each color you have); tint each dough by stirring in a few drops of desired food color.
2. Shape 1/3 cup of each color of dough into a rope about 5 inches long and 1 inch in diameter. Place ropes side by side and a little more than 1/4 inch apart on floured surface; roll until 1/4 inch thick. Cut with 2- to 2 1/2-inch egg-shaped cookie cutter so each cookie has 3 (or however many) colors. Sprinkle with sugar. Place 2 inches apart on ungreased cookie sheet. Repeat with remaining dough. (When re-rolling dough scraps, carefully lay matching colors together.)
3. Bake 7 to 9 minutes or until edges are light golden brown. Cool 1 minute; remove from cookie sheet to wire rack. Cool completely, about 30 minutes. Spread frosting on bottoms of half the cookies. Top with remaining cookies.
