Tetris Cookies

My favorite video game of all time is Tetris. It’s simple, addicting, and oddly soothing. My love of the game was intensified when the tetriminos were colorized. Each tetrimino has a color and I stayed true to that with these cookies. I’m not overly thrilled with these cookies because my icing was more watery than it should have been — and the end result is a bit bumpy. But I try not to be one of those baking bloggers who only posts treats that turn out to be “perfect” — so here these are!

If you are a new to decorating with royal icing, here are some helpful tips and links:

  • I used my grandma’s sugar cookie recipe, which is listed below.  Another good cut-out cookie recipe can be found at Bridget’s wonderful Bake at 350.
  • I used a royal icing recipe from Annie’s Eats, which is listed below.
  • If you are new to decorating with royal icing, please visit this post by Annie’s Eats, which will teach you about outlining and flooding.  Bake at 350 is also a great resource for cookie decorating and ideas (I love Bridget’s book, too!).

Here are the specifics on how I made these cookies:

  • I bought the Tetris cookie cutters from Amazon. They come in a set, which costs about $15.
  • I used Wilton gel dyes – red (for the Z piece), orange (for the L piece), yellow (for the O piece), leaf green (for the S piece), sky blue (for the I piece), royal blue (for the J piece), and violet (for the T piece).
  • I outlined the cookies using white icing first — making the little compartments on each piece. When the outlines dried, I flooded the cookies with the corresponding colored icings.

Omi’s Sugar Cookies
Print Recipe
1 cup butter
1 cup sugar
1 large egg
1/2 teaspoon salt
3 cups flour
1 teaspoon baking soda
1/2 cup sour cream
1 teaspoon nutmeg

Beat butter and sugar. Add egg, sour cream, and nutmeg. Add dry ingredients gradually. Chill the batter overnight or for at least 4 hours. Roll out dough and cut with cookie cutters. Bake at 350F until golden (in true fashion, my grandma didn’t give a specific baking time. I baked the cookies for about 8 minutes).

You’ll get about three dozen Tetris pieces using this recipe. I’d suggest doubling the batch if you want more cookies.

White Royal Icing
4 cups powdered sugar, sifted
2 Tablespoons meringue powder
5 Tablespoons water

Combine all ingredients in the bowl of a stand mixer fitted with the paddle attachment. Mix on low speed until the sheen has disappeared and the icing has a matte appearance (about 7-10 minutes).  Transfer the contents of the mixing bowl to an air-tight container. This will be the stiffest consistency of the icing, and at this point it is still too stiff to use for decorating. Add water a very small amount at a time and stir by hand until fully incorporated. Continue until the icing has reached a consistency appropriate for piping.

You will most likely need to make two batches of icing for this project — because of all the colors involved.
