Daring Bakers - Graham Wafers and Nanaimo Bars

The January 2010 Daring Bakers' challenge was chosen by Lauren of Celiac Teen. She chose gluten free Graham Wafers and Nanaimo Bars. 101 Cookbooks and www.nanaimo.ca were her sources.

I was very keen on trying these, especially as I am interested in having some gluten free recipes in my repertoire. So many people I know are on gluten free diets and I would love to be able to bake for them too! The other reason I was keen is I had never heard of them before, as well as not knowing what graham crackers actually are, despite having heard about them.

Here is my attempt at the graham wafers.

Hmm not so waferlike; more like thick and gooey but they had a beautiful flavour of honey and whizzed up perfectly in the food processor as the base for the bars. I had trouble rolling it out because the mixture was so soft and gooey (thanks to it being the middle of summer), and I ran out of rice flour to help me out. So I put the mixture between two sheets of parchment paper and rolled it, then chucked it in the freezer for a while to harden so I could peel the top parchment sheet off, and then cut them up! Voila!


Making the bars was easy. I whipped up the middle layer quickly and added a wee bit of peppermint essence to the mix as I though it a rather boring flavour, and then melted the chocolate. I added oil into the chocolate instead of butter purely because it saved time and I had such a small amount. It still sets perfectly.

These are HUGELY sweet due to the middle layer but the base layer is delicious with the coconut and almonds and I decided this would be a good base for any gluten free slice so I am excited to use my leftovers for something else!


Here's the recipe:

Variations allowed:
• Although I highly recommend using gluten-free flours, as the chemistry is very interesting and the end result can be amazing, you are allowed to use wheat.
• If making them gluten-free, no wheat, barley, rye, triticale, kamut, spelt, durum, semolina, or other gluten containing ingredients may be used. Removing those ingredients ensures it is safe for those with Celiac Disease and other health issues where gluten causes problems. If you do plan on serving this to someone on a gluten-free diet, also ensure no cross-contamination occurs.

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.

Nanaimo Bars
Ingredients:

For Nanaimo Bars — 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)

For Nanaimo Bars — 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

For Nanaimo Bars — 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.

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 wheat 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.

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

Glad you liked them! I've never had peppermint Nanaimo bars, but I have seen them, especially around Christmas. I used wheat flour and my crackers were extremely crisp, especially because I kept forgetting them in the oven! I think you'll be able to come up with lots of great toppings for this yummy base!

oh, I bet the peppermint bars were great. I think peppermint and chocolate go together really well!
