HOWTO Make Tetris brownies

Fraske Design's got a great, simple tutorial for making your own Tetris brownies for hours of fun and pounds of flab:

Since I made these brownies thinner than normal, I also cut down the baking time. The baking process would have normally taken around 30 minutes, but this batch only took 10. I just kept an eye on the pan and took it out when it looked about right. The trick is to not let them bake too long.

Next, while the brownies were cooling, I mixed up my tetris color frostings into seven separate bowls. It turns out that Tetris colors have varied over the years, so I settled on matching the colors to the tetrads in the Free Tetris game online. My colors included yellow, orange, red, magenta, cyan, blue, and green. I achieved these colors mixing white vanilla frosting and food coloring accordingly.

How to Make Tetris Brownies (or Tetris Cookies) (via Craft)


  1. Have we come to the point where we need a tutorial for this? Sorry for the, uh, “snark,” but….

    Dang, it’s a pan of brownies with some colored frosting.

  2. @Elvis Pelt: You’re forgetting the complex step whereby you must draw a knife along the frosting to make the lines for the individual blocks. That’ll get you every time.

    Yea, I agree, while this sort of activity should be encouraged, I’m not sure I see the need for a HOWTO on this topic. Maybe a photoset of various people enjoying them, but the instructions kind of write themselves.

  3. 1 – Make pan of brownies
    2 – Cut into tetris shapes
    3 – Frost shapes with different coloured frosting
    4 – Make lines to denote blocks

    Still, I can’t be mad at brownies…

  4. I was hoping for quite a bit more from the original article. It’s trivially easy to split up a bunch of brownies into tetrads; far more interesting is the problem of determining the optimal packing of pieces that can fit into standard-sized baking pans.

    The problem is one of determining a packing of tetrads which closely approaches a normal statistical distribution[1] and still fills the pan to the edges (since baking non-rectangular brownie shapes is, um, challenging). There’s some interesting work to be done there, I think (ref. “Tetris is Hard, Even to Approximate” (Erik D. Demaine, Susan Hohenberger, David Liben-Nowell; arXiv:cs/0210020v1 ;

    [1]: even though those damned square blocks seem to come up at the worst possible time[2]… damn it!


  5. The “toothpick test for doneness” has given way to “took it out when it looked about right” and calling 911 for directions on making Tetris brownies.

  6. With all the legal jazz the Tetris folk throw at people, I’m surprised you of all people Cory didn’t give us a heads up on the strong possibility of the Russian mob throwing strange bricks through our windows!

  7. So, my question is, where is that free tetris on line game site? I can play whilst the brownies are cooking.

    I live in a household with a six year old boy, the brownies are not gonna last long enough to cut into shapes and then be frosted.

  8. This post wouldn’t annoy me if they looked amazing. Or even pretty good. But they look really, really bad.

    I’m guessing Cory feels obligated to post this because a fan submitted it.

  9. I’ve never had frosting on a brownie before. Is this a regional thing?

    In Soviet Russia, the brownies frost YOU.

  10. Thoughts before reading comments: Hooray! Brownies! Delicious!

    Thoughts after reading comments:
    C’mon, people, brownies! How can you say anything negative about brownies? Especially when they’re shaped like tetris pieces. Who cares if it’s easy to make.

    It’s obviously posted more for the idea than for detailed instructions. -_-
