Gluten-Free Graham Wafers and Nanaimo Bars (Daring Baker)

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.

Remember the Daring Cook challenge I blogged about a couple of weeks ago? This one is the Daring Bakers version. I never would have thought to make homemade graham wafers, much less gluten free, so already I’m trying new things!

Finding the ingredients was a challenge in itself. I was able to find most of the flours at my local grocery store, but I did have to head out to my favorite health food store for two of them. Once I figured out that icing powder is powdered sugar I realized I have a package of that. The custard powder I was able to find at a specialty grocery store (Horrocks). You can substitute vanilla pudding mix, but I am always up for an excuse to go to Horrocks.

I decided to use rice flour instead of sweet rice flour because I accidentally bought the wrong kind. Boy, was the dough ever sticky! I decided that since I was really only making this for the crumbs, I’d sort of spread it on parchment paper on a baking stone, chill 2 hours, and then bake it without going through all the hassle of making nice neat little graham crackers.

The bars went together really fast. As I was cooking the base layer I was in love already. I splurged and pulled out the fair trade organic cocoa, and the richness was incredible as I stood over the stove. I did the middle layer in my KitchenAid, and licked the beaters. Oh my word, such sweetness! I did have to add a little extra raw milk because it wasn’t fluffing, but it was soooo good. And then the top layer was of course just semisweet chocolate and butter. HEAVENLY. All the guys at DH’s brew party loved them.

“Phenomenal.”

“Like tiramisu only without the nasty coffee flavor.”

“This is sooooo good.”

The recipe as it was given to us:

Preparation time:
• Graham Wafers: 30 to 45 minutes total active prep, 2 ½ hours to overnight and 45 minutes inactive prep.
• Nanaimo Bars: 30 minutes.

Equipment required:
• Food Processor
• Bowls
• Parchment paper or silpats
• Cookie sheets
• Double boiler or pot and heatproof bowl
• 8 by 8 inch square pan
• Hand mixer or stand mixer (You may use a wooden spoon, but this makes it much easier!)
• Saucepan

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.

Additional Information:

These bars freeze very well, so don’t be afraid to pop some into the freezer.

The graham wafers may be kept in an airtight container for up to 2 weeks.

The nutrition information:

You don’t want to know. When I asked some of my Canadian friends in Ontario if they had heard of these bars, they said of course, they’re from BC (British Columbia) and very rich. They’re common around Christmastime and are sold in big slabs, although you really don’t want to eat them in a big slab.
