Daring Bakers January Challenge: Oh, Canada...

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 http://www.nanaimo.ca/.

This challenge introduced me to the Canadian sweet tooth! Nanaimo Bars are a dessert favorite in the Great White North, and all of the Canadian Daring Bakers went nuts. They were so excited. The rest of us scratched our heads and wondered how to pronounce them. Nannymo? Nahnee-i-mo? Nana-eemo? Turns out, it's Nah-nye-mo. I actually had to ask one of my Canadian students to explain it to me.

These uber-rich, super sweet and very very decadent bars are really easy to put together. The bottom layer is a mixture of crushed grahams, coconut, chocolate, almonds and butter. The middle layer is called a custard, but it's really just a layer of buttercream icing made with vanilla pudding mix, powdered sugar, and more butter. The final layer is a ganache, made with melted chocolate and oh yeah...more butter!

In order to make the recipe more challenging, we were asked to bake our own graham crackers. The original challenge called for gluten-free ingredients, but I wasn't really comfortable spending money to buy new flours (sweet rice, sorghum, tapioca starch) that I would never use again. Luckily, Lauren gave us the option of using AP Flour.

Did you know that homemade graham crackers smell AMAZING? And working with the dough will probably make you cry, it's so frustrating. But they are truly delicious. The final bars, though? Meh...not really my thing. I wasn't expecting the middle custard layer to be a true buttercream and it was just too rich for me. I would have enjoyed them more if I had spread on only a thin layer. Alex's coworkers; however, devoured them!

Recipe

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

If making the graham crackers with wheat, replace the gluten-free flours (tapioca starch, sweet rice flour, and sorghum flour) with 2 ½ cups plus 2 tbsp of all-purpose flour, or wheat pastry flour. Watch the wheat-based graham wafers very closely in the oven, as they bake faster than the gluten-free ones, sometimes only 12 minutes.

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.


Nanaimo Bars

Ingredients:
Bottom Layer
1/2 cup (115 g) (4 ounces) Unsalted Butter
1/4 cup (50 g) (1.8 ounces) Granulated Sugar
5 tablespoons (75 mL) Unsweetened Cocoa
1 Large Egg, Beaten
1 1/4 cups (300 mL) (160 g) (5.6 ounces) Gluten Free Graham Wafer Crumbs (See previous recipe)
1/2 cup (55 g) (1.9 ounces) Almonds (Any type, Finely chopped)
1 cup (130 g) (4.5 ounces) Coconut (Shredded, sweetened or unsweetened)

Middle Layer
1/2 cup (115 g) (4 ounces) Unsalted Butter
2 tablespoons and 2 teaspoons (40 mL) Heavy Cream
2 tablespoons (30 mL) Vanilla Custard Powder (Such as Bird’s. Vanilla pudding mix may be substituted.)
2 cups (254 g) (8.9 ounces) Icing Sugar

Top Layer
4 ounces (115 g) Semi-sweet chocolate
2 tablespoons (28 g) (1 ounce) Unsalted Butter

Directions:
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.

3. For Top Layer: Melt chocolate and unsalted butter over low heat. Cool. Once cool, pour over middle layer and chill.

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. Mine lasted about that long.

For the Nanaimo Bars, if making with wheat, replace the gluten-free graham wafer crumbs with equal parts wheat graham wafer crumbs!
