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 have never had a Nanaimo Bar.

If you are like me and you are wondering what it is, Lauren described it perfectly,  “Nanaimo Bars are a classic Canadian dessert created in none other than Nanaimo, British Colombia…  3 layers: a base containing graham crackers, cocoa, coconut and nuts, a middle custard layer, and a topping of chocolate.”  I might add that they are a very tasty treat 🙂

This challenge was a two parter: Graham Wafers and Nanaimo Bars.  We had an option to make the Wafers Gluten-Free and I decided to just do it.  I have never experimented with Gluten-Free baking because of the obvious reason: no one in my immediate family or I has a gluten allergy.  What better time to start a new adventure.

Gluten-Free Adventure part 1: Find all the ingredients.  Surprisingly the only thing that was not readily available was Sweet Rice Flour.  I was actually able to find everything else.  I ended up substituting White Rice Flour for the Sweet Rice Flour, and I came across a small package of Birds’ Custard Powder, which was a little godsend.

Gluten-Free Adventure part 2:  GRAHAM WAFERS. Put everything in a food processor 🙂  The dough actually came together really nicely.  I put it in the fridge and then proceeded to forget about it for 2 days, opps.  When it finally came down to it, I rolled the entire piece of dough out, cut out my squares, and baked up the squares and the scraps.  I figured I was going to be making graham wafer crumbs for the bars so I could  grind up the scraps and save the pretty wafers to eat 🙂  The less work I have to do the better.  Speaking of less work, I ground up the almonds and wafers together in the food processor too.

Putting the bars together was pretty straight forward and I didn’t encounter any problems.  Once the bars were set, I cut them into 30 squares.  Which was the perfect serving because these bad boys are sweet and yummy.  I proceeded to eat 2 squares and then packaged up the rest for Mike to take to work.  These were an absolute hit.  Mike was a little disappointed that he didn’t have any to bring home because he really liked them too.  I offered to make another batch because I have enough ingredients to do it again, but he declined….for now 🙂

For Gluten-Free Graham Wafers

Ingredients
1 cup (138 g) (4.9 ounces) Sweet rice flour (also known as glutinous rice flour)
3/4 cup (100 g) (3.5 ounces) Tapioca Starch/Flour
1/2 cup (65 g) (2.3 ounces) Sorghum Flour
1 cup (200 g) (7.1 ounces) Dark Brown Sugar, Lightly packed
1 teaspoon (5 mL) Baking soda
3/4 teaspoon (4 mL ) Kosher Salt
7 tablespoons (100 g) (3 ½ ounces) Unsalted Butter (Cut into 1-inch cubes and frozen)
1/3 cup (80 mL) Honey, Mild-flavoured such as clover.
5 tablespoons (75 mL) Whole Milk
2 tablespoons (30 mL) Pure Vanilla Extract

Directions:
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 350 degrees Fahrenheit (180 degrees Celsius).
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 (300 mL) 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.

    Glad you liked them! I gave most of mine away too, though there’s still one in the fridge, and if I listen carefully, I can hear it calling my name:) Going to check right now…
