Gluten-Free Graham Crackers and Nanaimo Bars

Gluten-Free Graham Crackers and Nanaimo Bars

The January 2010 Daring Bakers’ challenge was hosted by Lauren of Celiac Teen. Lauren chose Gluten-Free Graham Wafers and Nanaimo Bars as the challenge for the month. The sources she based her recipe on are 101 Cookbooks and www.nanaimo.ca.

I'd been wanting to experiment with coconut flour, so when I saw January's gluten-free Daring Bakers challenge, I knew I'd have my chance. Not being a gluten-free baker, I wasn't sure exactly how to make a substitution to the recipe Lauren provided, but I decided to just take a stab and play with the results. Call it dumb luck, but the consistency was just as I thought it should be, and the dough rolled out perfectly for gluten-free graham crackers.

Straight out of the oven these crackers had a distinctly graham cracker flavor, but because I'd used coconut flour there was a nutty undertone. They crisped within an hour, and I used them immediately for the second part of the challenge: Nanaimo Bars. But before I leave the graham crackers, I should mention that they got soggy after 24 hours, even when I stored in an airtight container. Frankly, I like them better this way, but they are awfully leathery.

Nanaimo Bars. I'd never heard of these until I moved to Seattle, and I'd never thought to make them until this month's challenge. When I got going, they were very easy to assemble, and even better they store well in the freezer.

I decided on a simple variation of flavors because I used coconut flour in the graham crackers. As a nod to my Texas roots, I made German Chocolate Nanaimo Bars. Sweeter than my Granny's German Chocolate Cake, the base layer was cocoa, flake coconut, graham crackers, and pecans. The middle layer was the traditional Bird's Custard flavored icing and on the top I spread German's sweet chocolate (and topped with pecans). Genius. Now I can sate the German chocolate cake craving with a smaller gluten-free option!


Gluten-free Graham Crackers
1 c sweet rice flour (also known as glutinous rice flour)
1+1/4 c coconut flour
1 c light brown sugar, lightly packed
1 tsp baking soda
3/4 tsp Kosher salt
7 T unsalted butter (Cut into 1-inch cubes and frozen)
1/3 c honey, mild-flavoured such as clover.
5 T whole milk
2 T vanilla

  1. In the bowl of a food processor fitted with a steel blade, combine
    the flours, brown sugar, baking soda, and salt. Pulse on low to
    incorporate. Add the butter and pulse on and off, until the mixture is
    the consistency of a coarse meal. If making by hand, combine
    aforementioned dry ingredients with a whisk, then cut in butter until
    you have a coarse meal. No chunks of butter should be visible.
  2. In a small bowl or liquid measuring cup, whisk together the honey,
    milk and vanilla. Add to the flour mixture until the dough barely comes
    together. It will be very soft and sticky.
  3. Turn the dough onto a surface well-floured with sweet rice flour and
    pat the dough into a rectangle about 1 inch thick. Wrap in plastic and
    chill until firm, about 2 hours, or overnight.
  4. Divide the dough in half and return one half to the refrigerator.
    Sift an even layer of sweet rice flour onto the work surface and roll
    the dough into a long rectangle, about 1/8 inch thick. The dough will
    be quite sticky, so flour as necessary. Cut into 4 by 4 inch squares.
    Gather the scraps together and set aside. Place wafers on one or two
    parchment-lined baking sheets. Chill until firm, about 30 to 45
    minutes. Repeat with the second batch of dough.
  5. Adjust the rack to the upper and lower positions and preheat oven to 350F.
  6. Gather the scraps together into a ball, chill until firm, and
    reroll. Dust the surface with more sweet rice flour and roll out the
    dough to get a couple more wafers.
  7. Prick the wafers with toothpick or fork, not all the way through, in two or more rows.
  8. Bake for 25 minutes, until browned and slightly firm to the touch,
    rotating sheets halfway through to ensure even baking. Might take less,
    and the starting location of each sheet may determine its required
    time. The ones that started on the bottom browned faster.
  9. When cooled completely, place enough wafers in food processor to
    make 1 ¼ cups of crumbs. Another way to do this is to place in
    a large ziplock bag, force all air out and smash with a rolling pin
    until wafers are crumbs.

German Chocolate Nanaimo Bars

Bottom Layer
1/2 c unsalted butter
1/4 c granulated sugar
5 T unsweetened cocoa (I used Drost Dutched process cocoa)
1 large egg beaten
1+1/4 c gluten free graham cracker crumbs (see previous recipe)
3/4 c pecans, roughly chopped
1 c large flake coconut

Middle Layer
1/2 c unsalted butter
2 T+ 2 tsp heavy cream
2 T vanilla custard powder (Such as Bird’s. Vanilla pudding mix may be substituted.)
2 c powdered sugar

Top Layer
4 oz German's sweet chocolate
2 T unsalted butter

  1. For bottom Layer: Melt unsalted butter, sugar and cocoa in top of a
    double boiler. Add egg and stir to cook and thicken. Remove from heat.
    Stir in crumbs, nuts and coconut. Press firmly into an ungreased 8 by 8
    inch pan.
  2. For Middle Layer: Cream butter, cream, custard powder, and icing
    sugar together well. Beat until light in colour. Spread over bottom
    layer.

Jenny..your comment was so

Jenny..your comment was so uncanny, as I've been waxing poetic over Joe's stone crab legs the past week LOL I need to get to Miami soon!

That said, your bars turned out beautiful as did the photos. Amazing job as always!

Wonderful job on my

Wonderful job on my challenge! I'm so glad the coconut worked well and I love how you played off the coconut in the wafers for your bars =D.

I'd never heard of the

I'd never heard of the nanaimo bar until recently but now that I have, I can't wait to try one!

The use of coconut flour was an interesting. The coconutty undertones sounds like it would have added something special to the overall flavour of the bar compared to using regular flour.

Coco vs. AP flour

Simon,

True - the coconut definitely added flavor to the graham crackers, but given that this was a GF challenge, I haven't tried it with plain AP flour. What I can tell you is that the grahams were pretty dense compared to what I think of as a crunchy and pretty flaky traditional graham cracker, but I don't know if that was a result of this being GF or coco flour specifically. Totally worth another try.

And I read this morning on Lis's site (La Mia Cucina) that she made the filling with espresso powder and cream cheese - a variation I hadn't considered, but will be trying if and when I do these again!

Happy baking!
Jenny

Thanks for all the great comments!

Pontch - they tasted pretty good too!

Mary - Totally agree. While I *could* eat a whole German Chocolate Cake, I would regret it somehow! This isn't so bad - and because they store well, I can pop one out anytime I've got the craving.

Jeanne - Sadly, they were too good. I've been distracting myself with pie so I won't eat all that's left of the bars.

Y - Well, I will admit this - the coconut flour wasn't cheap (Bob's Red Mill, 1 package about $7), but I know that the ingredients I subbed for would have been about the same price if not more. I'm really intrigued by coconut flour, and I'm looking for another opportunity to use it. Maybe a GF pie crust, if I can get it flaky enough.

ap269 - Your German would be the real thing. But the German in my case refers to a brand of chocolate (German's) that has a sweet version, probably 55% cocoa (or less). It's a really common dessert in the American south, but when I've made it with quality goods, it just doesn't taste all that good. It's a cake on the cheap. I'm sure that the better ingredients would have translated well to these bars, in any case!

Your bars look really nice. I

Your bars look really nice. I guess, I can claim I made German chocolate bars, too - hehe, because I am German, live in Germany, and used the store-brand bitter-sweet chocolate :o)

Coconut flour in this sounds

Coconut flour in this sounds fantastic! I've been that ingredient around but have yet to try baking with it. Your bars look so perfect too.

These look amazing! I love

These look amazing! I love your German chocolate adaptation, I bet it was very tasty!

These look fantastic!

What a great idea! Ideas, I mean--the coconut flour and the German chocolate version of the Nanaimo bars. I love German chocolate cake, but don't often want or need a whole cake, so this is perfect. I made a much more traditional version, but need to revisit these again...

Nanaimo

Beautiful Job
your Nanaimo bars look amazing.
