Black-Bottom Coconut Bars

I found this recipe when I was searching for something to make for a friend’s birthday treat. Luckily for me, that just happened to be a friend who loves coconut. I don’t get many chances to bake with coconut, so I take every opportunity I get.

These bars feature a wonderfully, gooey, coconut-y mixture on top of a thin brownie. You know I’m not going to stray too far from chocolate. That little bit of chocolate is just the right amount for the topping. These are gooey, sticky little bars, but they’re worth the mess.

The only thing I might change about these would be to add some pecans to the top. I think sprinkling some coarsely chopped pecans on top for the last 10 minutes or so of baking could be interesting. These would become very much like bite-sized German chocolate cakes.

If you can exercise some patience, I recommend waiting a day to eat these. I tried one right after they cooled and was only moderately impressed. But, I decided to give them another try the next day and was pleasantly surprised to find that they were much, much better. For all you coconut fans, waiting a day to eat them would certainly be a test of your will-power. And it will be worth every minute.

Black-Bottom Coconut Bars

Prep Time: 25 minutes

Cook Time: 45 minutes

Yield: 16-24 bars

Black-Bottom Coconut Bars


    For the crust:
  • 1/2 cup unsalted butter, plus more more pan
  • 1/2 cup granulated sugar
  • 1/4 teaspoon salt
  • 1 large egg
  • 1/4 cup unsweetened cocoa powder
  • 1/4 cup all-purpose flour
  • For the topping:
  • 2 large eggs
  • 3/4 cup granulated sugar
  • 1/2 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 7 ounces sweetened, shredded coconut – reserve 1/2 cup for sprinkling on top


To make the crust:

Preheat oven to 375°. Line a 9-inch square baking pan with aluminum foil, leaving an overhang. Butter bottom and sides of foil.

Using a microwave-safe bowl, melt butter in microwave. Whisk in sugar and salt. Whisk in egg, then cocoa powder and flour. Mix until smooth. Spread evenly in prepared pan.

Bake for 10-15 minutes. The sides should be beginning to pull away from the sides of the pan. Set aside to cool.

To make the topping:

Whisk eggs with sugar and vanilla. Mix in flour and coconut.

Drop mounds of topping onto chocolate base. Spread and press into base with moistened fingers. Sprinkle with 1/2 cup coconut.

Bake 25-30 minutes, or until a toothpick inserted in the center comes out with moist crumbs attached. Cool completely in pan. Then, remove from pan using aluminum foil overhang. Peel off foil and cut into bars.


Store in an airtight container for 3-4 days.

    Dang, girl! These look divine. Seems like a perfect flavor combination. And I’m loving the lead photo!

    these look good! i made something like this a couple years ago, but the proportion between brownie and coconut was 50-50. i don’t think you can go wrong either way when it comes to coconut and chocolate.

    Haha. I’ve had this recipe printed out in my file for like almost a year now… I just haven’t gotten the nerve to try them yet. I LOVE coconut, but from the pic on Marthas website they didn’t look so gooey and yummy as your pics look.

    This recipe is officially moving from the “will maybe make one day” stack. To the “” Yum!

    I made these a month or so ago and LOVED them! They taste amazing… and now I want to make them again!

    Being a mega coconut fan, I probably couldn’t wait too long for one of these beauties.

    All things coconut….mmmm. And you had me at “black-bottomed!”

    I just came to your site yesterday while I was looking for a cherry and chocolate chip cookie. Your’s are great. I was looking around your site today and you have some super looking recipes. I happen to be a chocolate, coconut, well almost any nut, lover. And all the brownies, I can’t wait to give them a try. Thanks for sharing.

    these would be far superior to german chocolate cake. why, you ask? more coconut shtuff, less cake! lovely work. :)

  9. Mandie @ (roaring)mama February 12, 2010 Reply

    Mmmmm…..These look divine. I love chocolate and coconut together. It’s just the best combination. I can’t wait to make this.

  10. That is gorgeous. As it happens, I love the chocolate coconut combo but even if I didn’t , that would still make me look twice! I might add chopped dried cherries to the coconut too – you know what they say, “Too much of a good thing can be be wonderful” 😀 Beatiful photos!

    Remember Hello Dollies? They have a graham cracker crust but this elevates that. And of course, they cut out the fuss of measuring sugar and flour and just go straight to the Eagle Brand. And yes, some chopped pecans and a few Belgian chocolate chips in the last minutes could certainly be a FABULOUS thing.

    These look so great! I love coconut and have had it on the brain for the past week!

  13. Jennifer February 13, 2010 Reply

    Those look so yummy. I love coconut and I love chocolate but I like that the chocolate layer on these is really thin so it enhances the coconut but doesn’t overwhelm it.

  14. Lucy February 13, 2010 Reply

    I also always grab a coconut baking opportunity, as my family are not great coconut fans (I know – weird!) and only rarely feel like eating it. These sticky little bars look delicious – it would be a severe willpower test to wait until the next day to try one!

    I always like coconut flavored things–it reminds me of some of my tropical vacations–pairing it with chocolate is even better! :-)

    First time on your site. Fantastic photos! Recipes look pretty awesome too! As a matter of fact, I think I went up a pant size just browsing. I made this recipe from Martha Stewart Everyday Food magazine. They were a big success. You just can’t go wrong with chocolate and coconut. Maybe some almonds and you’ve got an Almond Joy! Trick or Treat for grown ups!

    I made these in December and would make them again:

    1. Exactly as the recipe is written.

    2. Halving the coconut layer and doubling the brownie layer.

    3. Only using the coconut layer and baking them as the best macaroons ever.

    They were a hit at the party that I made them for.

  59. Marisa September 13, 2010 Reply

    Wonder why they would be better the next day? Would imagine that they might be denser & hence more chewy once cooled down.. At any rate, they look amazing though and as a coconut lover I am definitely tempted.

    These were so yummy!! Perfect blend of chocolate and coconut chewiness!!I only baked the base for 10 minutes and the top for 20. Just right.

    I noticed the ingredient sugar is listed twice in the directions:
    “Whisk in sugar and salt. Whisk in egg, then sugar and flour. ”

    I assume cocoa was supposed to replace one of these….could you clarify?
