Black-Bottom Coconut Bars

Team up two familiar treats -- a rich chocolate brownie and a chewy coconut macaroon -- and indulge in a decadent sweet.

  • prep: 45 mins
    total time: 1 hour 30 mins
  • yield: Makes 24




For Chocolate Base

  • 1/2 cup (1 stick) unsalted butter, plus more for pan
  • 1/2 cup sugar
  • 1/4 teaspoon salt
  • 1 large egg
  • 1/4 cup unsweetened cocoa powder
  • 1/4 cup all-purpose flour (spooned and leveled)

For Coconut Topping

  • 2 large eggs
  • 3/4 cup sugar
  • 1/2 teaspoon vanilla extract
  • 1 cup all-purpose flour, (spooned and leveled)
  • 1 package sweetened shredded coconut (7 ounces), 1/2 cup reserved for sprinkling


  1. Step 1

    For chocolate base: Preheat oven to 375 degrees. Line a 9-inch square baking pan with aluminum foil, leaving a slight overhang; butter bottom and sides of foil (not overhang).

  2. Step 2

    Place butter in a large microwave-safe bowl; melt in microwave. Add sugar and salt; whisk to combine. Whisk in egg, then cocoa and flour until smooth. Spread batter in prepared pan.

  3. Step 3

    Bake just until sides begin to pull away from edges of pan, 10 to 15 minutes (do not overbake). Let cool slightly while preparing coconut topping. Keep oven on for topping.

  4. Step 4

    For coconut topping: In a medium bowl, whisk eggs with sugar and vanilla. Gently mix in flour and coconut (except 1/2 cup reserved for sprinkling).

  5. Step 5

    Drop mounds of mixture over chocolate base; spread and pat in gently and evenly with moistened fingers. Sprinkle with reserved 1/2 cup coconut.

  6. Step 6

    Bake until golden and a toothpick inserted in center comes out with moist crumbs attached, 25 to 30 minutes. Cool completely in pan. Lift cake from pan, peel off foil, and cut into 24 bars.

    Such a shame, I followed this recipe to the letter, and I've ended up with a layer of brownie, and a layer of coconut cake......tastes Ok but after reading the recipe again I believe the "macaroon" topping needs to be made with egg whites, and this is not clarified in the recipe! :( please adjust so others aren't disappointed!

    To make it gluten free, what type of flour would you suggest?

  • 17 Mar, 2014

    Obviously the one with the brownie base cannot be used for Passover. I will try the more traditional ones instead of buying 10 cans of the pre-prepared and full of preservatives ones however.

  • 23 Dec, 2013

    If I make on Christmas Eve, how do I store for the next day? Fridge or counter in a container? Helpppp

    Absolute hit...made me love coconut in baked goods. This is my go to for potlucks, always a hit.

  • 9 May, 2013

    I did this with kids, they love it.

  • 31 May, 2012

    The written recipe calls for 1/2 teaspoon vanilla extract, but the video calls for 1 teaspoon vanilla extract. Go with the 1 teaspoon vanilla extract - much better. I have also made this with a tablespoon of rum instead of vanilla, and it is nice, too!

    I have to be honest and say, I did not care for these. I love coconut and chocolate, but these just seemed plain to me, neither layer had much flavor and the texture seemed off as well. I don't usually post negative comments, if i think that it may in any way be my own fault. But, I'm pretty sure in this case it wasn't. They were OK. I can't say I would ever make them again.

  • 17 Jan, 2011

    These were easy to make and tasted wonderful! Highly recommend.

  • 11 Jan, 2011

    Sounds delicious. Would love to try it, but I cook a lot for large church groups. Rather than cooking several 9x9 pans, does anyone know if this recipe can be doubled for a 13x9 pan? How does it altar the cooking time or temp?

  • 30 Dec, 2010

    These were really fun and easy to make.
    I saw the video and my batter didn't seem to be as thick as the ones in the video. I'm pretty sure i did everything correctly.
    But! They still came out good and they smelled and tasted delicious!
    coconut lovers like my mom loved this but other people in my family didn't seem to like it much. This bar tasted bland on the first bite but i fell in love with it on my second bite.

  • 18 Dec, 2010

    Yummy ... I used the recipe as is and they came out delicious.

  • 14 Nov, 2009

    Im making these right now as I speak!! Theyre in the oven and smell amazing!! Im taking them to a party later and hope people like them! I will let you know what I think of them once they come out!!

  • 16 May, 2009

    I've been looking for this recipe for a very long time. I ate them a few years ago but wasn't able to get the recipe. Love the brownies but my center came out really gooey even when the toothpick had come out clean. I think I didn't bake it long enough before putting the topping on. I will definitely try this again.

  • 27 Mar, 2009

    I liked those but I found the coconut topping a little too dry so I made them again but used 1/2 Martha's coconut macaroon recipe, reduced heat to 300 to bake the topping. Baked for 30 mintues . That was much better. Very yummy.

  • 11 Feb, 2009

    I recently made these for a friend's bridal shower. They were a HUGE hit. If you love coconut you have to make them. I did a double batch so i would have some left for me.

  • 10 Feb, 2009

    Unless I am missing something I do not see any chocolate besides the powder in this recipe. Perhaps an unfortunate misprint. They sound delicious.

  • 17 Sep, 2008

    I made these last Christmas. Everyone LOVED them.

  • 8 Sep, 2008

    If you love coconut, you'll really enjoy this recipe. The brownie is moist with a chewy coconut layer on top. This recipe is very easy. I made a double batch in a 9x13 pan, so I baked them for the maximum bake time both times, and they turned out perfectly. These are really yummy, and I highly recommend it for all coconut-lovers.

  • 3 Sep, 2008

    These are wonderful! I sprinkled chocolate chips over the coconut before baking a second time. The didn't last long.

  • 27 Aug, 2008

    Easy and delicious!! Very chewy.

  • 25 Aug, 2008

    Love this recipe! Much easier to make than I thought from looking at the recipe! They were excellent!!

  • 25 Aug, 2008

    Love this recipe! Much easier to make than I thought from looking at the recipe! They were excellent!!

  • 22 Aug, 2008

    These are so easy to make. So wonderfully moist. I did not have to make them more than 25 minutes, carefull not to let the coconut burn. Will be making this again.

  • 18 Aug, 2008

    These were so easy to make and they taste so amazing! The chocolate base really compliments the coconut filling. I've had to hold myself back from eating them all in one day! Perfect with a big glass of milk!

  • 18 Aug, 2008

    Nice change of pace from a basic brownie and easy too.

  • 18 Aug, 2008

    I made these today for a pool party. AWESOME!
    They are soooo yummy! Rich

  • 16 Aug, 2008

    I made these today and they were easy and really good! I added milk chocolate chips to the chocolate crust just because almost everything tastes better with chocolate chips.

  • 16 Aug, 2008

    This is a great bar to add for Xmas baking. It should make a hit as it is not too rich or too sweet. Just right. My husband who loves brownies raved about this one. Will make again and will pass it on as well.

  • 15 Aug, 2008

    Oh. My. Goodness. I made these today and they were AWESOME! Had to adjust my cooking time because I already had something else going in the oven t 350 degrees, and my 9" pan was in use, so used a small oblong Pyrex dish. These were perfectly sweet and the coconut was not overpowering at all. The coconut mixture was thick, but not hard or tough. Spoon the flour to measure, don't scoop! The brownie style crust was a wonderful touch. Just simply perfect. Definitely a keeper!!

  • 15 Aug, 2008

    I have made these for several different family gatherings and there is never any to come home with!! Great recipe.

  • 15 Aug, 2008

    This reminds me of a recipe that my mother made when we were it. Charliemom1, you might want to check your oven temperature to make sure it's accurate. KatieRuMu, regardless of what you have heard, studies have shown that there is absolutely no difference between the shiny and dull side of the aluminum foil and which side is in or out.

  • 15 Aug, 2008

    Wow that sounds delicious, I can't wait to try it. Coconut is my favourite!

  • 22 Feb, 2008

    I thought this was a delicious desert even though I made the foolish mistake of having the shinier side of the foil facing outwards. It was so moist! And I love coconut! My only reservation in that the brownie part isn't too sweet. I might add just a little more sugar next time and there definitely will be a next time! Yummy!

  • 23 Jan, 2008

    I made these for my office. Everyone loved them! The combination of flavors was just right!

  • 18 Jan, 2008

    These bars were very easy to make and delicious. If you like coconut, you will love these bars.

  • 17 Jan, 2008

    Really delicious and easy bar cookie. The chocolate and coconut combination was a big hit with my family. Gobbled them up. Didn't change a thing on the recipe.

  • 13 Jan, 2008

    This recipe turned out really well. I only baked the coconut top for 20 mins but it was cooked perfectly and really moist. A nice combination and I will definitely be making this again.

  • 8 Jan, 2008


  • 21 Dec, 2007

    I actually tried this recipe and it was pretty good. However, I did use a 8x8 pan instead of a 9 - that may have made a slight difference, but it shouldn't have been drastic. I'd definitely use this recipe again!

  • 20 Dec, 2007

    this is not a good recipe at all. The coconut mixture becomes too hard and is tough.. Maybe cut way back on flour in the coconut mixture (or delete it all together? )

    would not make again
