Fudgey chocolate brownies.

Covered in fudgey chocolate frosting…

If you couldn’t tell, the theme of today’s post is chocolate fudge.

When I think of these brownies, I think of author Judy Blume, who wrote an entire series of books about Fudge: Double Fudge, Super Fudge, and Fudge-a-Mania. I’ll never forget my excitement when my third-grade teacher announced to the class that the next book we’d be reading was called Super Fudge.

A book all about chocolate??

Alas, it was really a book about an eleven-year-old boy. Each day I read intently, waiting to get to the part about the chocolate fudge. It never came… but at some point in the series, the little boy did eat a turtle.

Yeah, not the same thing. 😕

Unlike with the books, these brownies really are all about the fudge. What you see is what you get.


And no turtles.

Cosmic Fudge Brownies

Print this recipe


  • 1/2 cup cocoa powder (40g)
  • 1 cup spelt or all-purpose flour (140g) (Arrowhead Mills gf does also work.)
  • 1/2 tsp baking powder
  • 1/2 tsp salt
  • 2 tsp instant coffee granules (optional)
  • 1 cup xylitol or sugar (or coconut sugar) (190g)
  • optional: 1 cup mini chocolate chips
  • 6 tbsp silken tofu (For soy-free, you can use my black bean brownies recipe instead.)
  • 2/3 cup applesauce (160g)
  • 2 1/2 tsp pure vanilla extract (10g)
  • 1/2 cup coconut or vegetable oil (80g)
  • 2 tbsp milk of choice (30g)


  • 1/2 cup cocoa powder (40g)
  • 2 tbsp pure maple syrup or agave (30g) (you can sub liquid stevia to taste)
  • 1/2 cup liquid virgin coconut oil (75g)

Preheat oven to 325 and grease a 9×13 baking pan. In a large bowl, combine all brownie dry ingredients and stir well. In a separate bowl, combine all brownie liquid ingredients and stir well. Pour wet into dry and stir until evenly combined (but do not overmix), then transfer to prepared baking pan and cook 32-34 minutes. Allow to cool, and mix frosting ingredients together to form a sauce. Spread sauce over the brownies, then fridge or freeze 10-20 minutes and the sauce magically transforms into fudgey chocolate frosting! These brownies taste much richer the next day, after the flavors have had a chance to intensify.

Question of the Day:

Do you remember any of the books you read as a child?

I read all of Ann M. Martin’s Babysitter’s Club books, R.L. Stein’s Goosebumps books, and Beverly Cleary’s Ramona books, and was partial to series books. I hate when you start to develop a real relationship with a character only to have the book end.

    These look amazing! Just wondering about the serving size… how many brownies does it make? Thanks, Katie!

    1. It makes a 9×13 pan, so it depends on how big you cut them. I think it made around 25 of the size shown in the photos, but the nutrition facts are for 20 brownies (bigger than the ones in the photos).

  2. Quick question–what size of brownie did you base your nutrition info on? (Wondering how many servings you used for the total pan)

    1. 20 servings – It’s listed on the “nutrition facts” page :).

  3. Anonymous says:

    Oh man I hadn’t thought of those in years! I used to love ’em (even though they tasted like sugar covered plastic lol)

  4. I thought your black bean brownies already tasted EXACTLY like a cosmic brownie, so if you were actually trying for a cosmic browie with these it can only taste BETTER. Excited to give it a try 🙂

  5. These look delicious! I have never wanted to eat my computer screen more than I have today. 😉
    I love the Harry Potter series (they never get old), and I used to read the Box Car children.

  6. I completely agree that reading a series is so much better! I hate getting to know and love a character and not having more books to read with that character in it!

    These brownies looks absolutely decadent. I was just talking to a client of mine about Cosmic brownies and how rich they are earlier this week, he he. I love how you make treats healthier.

  7. Jill says:

    Oh, man! These look so good! I loved those Little Debbie Brownies growing up. Can’t wait to make these!

  8. Michelle says:

    This looks incredible!

  9. Heather says:

    Hi Katie,
    It would be helpful if you posted the serving size info clearly on both the recipe and nutrition pages for all of your recipes, right under the recipe title perhaps. Usually the number of servings and serving sizes (i.e. 20 servings from a 9×13″ pan) are buried in the description or comments.

    BTW, I loved the Babysitter’s Club and Ramona books too, but my favorite were the various American Girls series. Loved the history in those books!

    1. Hi Heather,
      The serving size for nutrition facts actually is stated in the nutrition facts, right under the label.

  10. I read a LOT of books growing up, it was definitely a favorite hobby of mine. I read all the Babysitter’s Club books, and I remember another series favorite of mine was the Boxcar Children. My absolute favorite book was Ella Enchanted by Gail Carson Levine (and I thought the book was very different from the movie that came out a few years back with Anne Hathaway).

    1. That was my #1 all-time favorite book as well! I completely forgot about that… and yes, the movie just did not compare 🙁

  11. Oh books…. I was all about The Babysitter’s Club, Nancy Drew, The Boxcar Children, and Little House on the Prairie books!

  12. Ooooh, those look so fudgey and delicious! I read all of the Babysitter’s Club books too….and of course, EVERYTHING by Judy Blume that I could get my hands on. Loved Are You There God, It’s Me Margaret.

  13. I used to LOVE eating these at lunchtime in high school! Thanks for re-creating a favorite!

  14. I, too, was a book worm as a child. My nose is still in books, but I will take a break to try these!

  15. Andie says:

    OMG!!! Katie you have NO idea how excited I am!! Little Debbie brownies have to be my biggest guilty pleasure EVER. I haven’t had one since I went vegan, so I am literally ecstatic. Thank you!!

    Also, I remember reading the Fudge and Babysitter’s Club books too! Whenever someone mentions a book that I read as a child it brings back all these nostalgic memories…alas, I don’t have as much time to read anymore, but when I do, I often need suggestions because I never can decide on what to read! :p

  16. I read TONS of books as a kid. I read all the American Girl books, Babysitter’s Club, Sweet Valley High, Nancy Drew, most of the Beverly Cleary books, etc…

    One summer the library did a book club for kids and for every so many books you read you would earn a slice of pizza from the local pizza place. I read constantly because I wanted to get FULL pizzas. I think I ended up getting 2 full ones plus an extra slice when it was all over. Good memories 🙂

  17. Mmm… these look so good! I remember eating Little Debbie’s Cosmic Brownies all the time as a kids, and while they were tasty they’re a little scary now. I’m pretty sure they could survive a nuclear holocaust!
    I was really into the Little House on the Prairie as a kid, I even own the box set of books!

  18. Jackie says:

    Can you provide more details about the type of tofu you used (firm, soft, light, regular, etc…)? Thanks! I really want to make these as my daughter loves Cosmic brownies and I cringe at the thought reading the ingredients and nutrituion facts…

    1. You can use silken OR you can blend mori-nu silken firm with the other liquid ingredients prior to mixing.

  19. To a fellow Katie: I LOVE your use of sprinkles and colours in that photo! I will have to try this one for sure.

  20. Emily Gorman says:

    LOVE these brownies and Judy Blume as well! My all-time favorite books were the Babysitter’s Club 🙂

    Is there a substitution for the tofu? More applesauce or something else? Thank you!!

    1. A substitution is listed in the recipe ingredients 🙂
