    (Gluten-Free!) Congo Bars

    Published Aug 31, 2010

    Jump to Recipe Print Recipe

    stack of delicious congo bars

    My big sister is amazing. She can do anything, and does, from trail running marathons to singing, dancing and playing the cello. She also has three jobs, four if you count having a teenaged daughter (though maybe that's more like 10 jobs..) and is one of the kindest, most caring and comforting people I know.

    ingredients for the bars

    If there are two things my gluten-intolerant sister likes best, it's booze and chocolate. I like to make her happy, so I created these gluten-free congo bars full of melty chocolate and a splash of dark rum just for her. (Not for me of course; no, this endeavor was completely selfless.)

    congo mix in a bowl

    Congo bars are blondies with the addition of shredded coconut. I normally don't care for coconut in this form, but something special happens in these bars - the butter, sugar and coconut form a pleasing 'gunginess;' a gooey, chewy, moist, stickiness that makes them extra addictive.

    The dark rum adds a mysterious layer of flavor, cutting the sweetness a bit, enhancing the bitterness of the chocolate and the toasty nuts somehow, and elevating the humble blondie to sophisticated new heights.

    The fine folks at Cook's developed a killer recipe that creates a bar cookie neither too thick nor too thin, chewy without being heavy, packed full of vanilla and toffee flavors, laden with toasty nuts and oozing chocolate in every bite. I've been making these bars for several years, and have come to tweak almost every ingredient to make these just to my taste - not too sweet or coconutty, packed with chocolate and full of flavor.

    Best of all (for my sister), these blondies are unobtrusively gluten-free, though you would never guess that their tender, chewy texture was due to a suave combination of sticky rice and tapioca flours.

    These pack well for a picnic or on-the-go snack. Or you could gild the lily by serving them warm with a scoop of ice cream (brown sugar, rum, coffee, vanilla or dulce de leche would all be exquisite). And some rum-flambeed banana slices wouldn't be amiss, either.

    At least, I know my sister wouldn't object.

    (Gluten-Free!) Congo Bars

    Print Recipe Pin Recipe
    These gluten-free bars are the perfect grab and go snack!
    Alanna Taylor-Tobin
    Prep Time: 10 minutes
    Cook Time: 35 minutes
    Total: 45 minutes
    Servings: 16 bars.

    Ingredients

    • 3/4 cup pecans
    • 1/2 cup shredded, unsweetened coconut
    • 3 ounces butter, melted and warm (6 tablespoons, 3/4 stick)
    • 1/2 cup plus 2 tablespoons light or dark brown sugar
    • 1 large egg (2 ounces)
    • 1 tablespoon dark rum
    • 2 teaspoons vanilla extract
    • 1/2 cup plus 2 tablespoons sticky (sweet/glutinous) white rice flour (3 1/2 ounces)
    • 2 tablespoons tapioca flour (1 ounce)
    • 1/2 teaspoon xanthan gum
    • 1/2 teaspoon baking powder
    • 1/2 teaspoon salt
    • 1 cup bittersweet (70% cacao mass) chocolate, coarsely chopped (6 ounces)

    Instructions

    • Position a rack in the center of the oven and preheat to 350º. Put sling of parchment paper or heavy aluminum foil in an 8x8" square baking pan, or grease the pan.
    • Spread the pecans on a small sheet pan and roast in the oven until golden and fragrant, 10 - 12 minutes. Remove and let cool, then break or chop into coarse pieces.
    • Meanwhile, spread the coconut on another small baking pan and bake for 5 minutes until golden, stirring once or twice. Set aside to cool.
    • In a large bowl, whisk together the sugar and egg. Slowly pour in the melted butter, whisking to combine, and add the rum and vanilla.
    • In a small bowl, whisk or sift together the flours, xanthan gum, baking powder and salt. Stir the dries into the wets. Stir in the cooled pecans, coconut, and chocolate chunks.
    • Spread the dough evenly into the parchmented pan. (It will look like not enough, but don't worry, it will rise in the oven.)
    • Bake until puffed, shiny and slightly cracked on top, and a toothpick inserted comes out with a few large, wet crumbs clinging (don't overbake), 15 - 20 minutes. Let cool at least 20 minutes before cutting (longer for cleaner-looking bars). Trim away the outer 1/2", then cut into 16 bars.
    • The bars are best the day they are made, but will keep, in an airtight container, for several days.

    Notes

    Adapted from Cook's Illustrated.
    If gluten isn't an issue for you, you can substitute 3/4 cup all purpose, whole wheat, or whole or white spelt flour for the rice and tapioca flours and omit the xanthan gum.
    Sticky rice flour, sometimes called "sweet" or "glutinous," is available at most well-stocked grocers. I usually use Mochiko brand. Regular rice flour may make for crumbly congo bars that don't hold together. If that's all you've got, try doubling the xanthan gum.
    Nutritional values are based on one of sixteen bars.

      Okay, first of all, YUMMMMMMM!!! I had these for the first time on Sunday and I am definitely addicted. My new favorite! And second, thanks for all the sweet things you say about me, and that you bake for me. I'm so lucky 'cause without you I wouldn't be able to eat any baked goodies aside from the dry, tasteless, ridiculously expensive gluten-free things you can buy in the health food stores. And one more thing, even though I don't like to cook, I DO love to read your blog because you write so well.

      Love, Jessie

        My brother does not like coconut either but I once made Magic Cookie Bars & put dessicated coconut in them - my brother loved them - he didn't know there was any coconut in it at all until I told him "you just ate some". He couldn't believe it. So try dessicated coconut (it is shredded really fine so you don't get the same taste). Happy baking!

      these look amazing! I'm vegan, and can easily sub the butter with a non-dairy butter, and since there's only 1 egg I can probably use an egg replacer without much change. I am so excited to try this recipe!! thanks for sharing!

        Hi Ester,
        I'm afraid that the bars would be crumbly, since it's the glutinous rice flour and xanthan gum that mimic the gluten in wheat flour and help the bars stick together. I once made then with regular white rice flour and guar gum, and they were very crumbly, though still tasty. Please let us know how they come out if you decide to experiment!

      I made these today and they are delicious. I'm trying out recipes for a bake sale and I have been asked for gf treats since they know I eat gf. These are definitely going up for sale. For any coconut haters out there, I can't taste it but it does amazing things for the texture. I did sub walnuts for the pecans and I probably won't add the rum when I make them for the bake sale.

      Made these today, and I agree with everyone: The texture is chewy and wonderful, just like pre-gluten free days for me. One thing I will say is that I cut the chocolate in half, and it was still wayyyy too much for me. And I'm a major chocolate lover.

      I will be cutting it down additionally next time. Other than this little change, the recipe was great! Thank you!

        Hi, Satpreet! I'm so glad you like the bars - thank you for your comment! I'm surprised to hear about them being too chocolatey for your chocolate-loving self, but of course do make the recipe to your taste. I'm curious whether you went by the weight or cup measure, and what kind of chocolate you used? In any case, happy baking. :)

      Love GF recipes that do not call for making up a recipe of flour mix A or B or Q as a precursor, though these are so delicious I bet I would put myself through that if it was the only way I could get my hands on more of them. Couldn't find rum in the house so I subbed kahlua. Holy moses, these are good! Thank you!

      Just a FYI...I made these using 1/2 coconut oil and 1/2 butter-VERY coconutty! I wish I would have used only butter.. Also, the coconut would have been burned beyond use after 5 minutes-3 would have been better. I used Kahlua and 3/4 cups chocolate. Will make again, I like the texture, with all butter.

      These were wonderful . . . and so easy! I only had light rum, so added a touch of molasses to it to make up the 1 Tbsp. Less time on the pecans and coconut toasting was needed for my oven, but the cook time was right on. My next attempt is going to be a vegan version for my daughter. Thank you for sharing - this is a keeper for us!

      Do you think it’s possible to make these without xanthan gum? My husband reacts very badly to it. I’d love a substitute suggestion if possible.

        Definitely! I published a recent recipe for gluten-free blondies that's based on this recipe, and I didn't use xanthan gum. You can just leave it out and the recipe should work beautifully!

I hope so because it's #piday and I'm sharing this cheesy spinach & leek quiche in a flaky gluten-free crust! 

The trick to getting a crisp crust is 
1. parbake the crust before adding the filling
2. brush the crust with egg white – this creates a barrier between the crisp crust and custardy filling
3. bake on the lower rack of the oven (preferably on a pizza stone if you've got one)

You'll get a golden, crisp bottom crust that keeps well for a couple of days in the fridge.

I had a pinched nerve in my ribs which felt like being stabbed in the side with a knife - so painful! This was probably caused by some overzealous (on my part) chiropractic work that had unintended consequences. 

Thank goodness for muscle relaxants and non-force chiros, I'm feeling much better after a very painful ~10 days! 

In other news, COOKIES. These oatmeal teff chocolate chip cookies were a late addition to my book, and I shared them on TBG 7 (!) years ago. 

I've been craving these cookies lately and wanted to see if they could be made refined sugar-free with coconut sugar (they can!) and I made some updates to the post body as well. 

Love love love the butterscotchy flavor of teff here, which pairs beautifully with chewy oats, toasty walnuts, and bittersweet chocolate. When perfectly underbaked, these stay moist and chewy for days. Or chill the dough balls and bake them off to order for warm, fresh cookies every day. Bojon appétit!
