muffin of the month, december 2015: gluten-free sweet potato ginger muffins


What is my favorite thing about baking, you ask?

Well, I have to test the recipes a lot before I feel confident calling them “my own,” let alone “successful,” and as a result…I get to eat a lot.

And if I’m making something buttery or high-carb-y, and my parents are on a diet, I have to eat a lot, a lot. I mean…I get to eat a lot, a lot.

When I was in Japan, I discovered the versatility of rice flour as a gluten-free ingredient, and ever since it’s become my goal to really get to know gluten-free ingredients, and to find recipes using the more common, easier-to-find, and cheaper ingredients.



Also, I started budgeting again and, y’all, it ain’t lookin’ good.

I spent the entire month of November on a muffin journey: testing out the previous monthly muffin, then attempting to make a gluten-free version, testing every flour combination imaginable (white rice + brown rice, white rice + buckwheat, white rice + half a bottle of cabernet sauvignon, white rice + soy flour, and white rice + chickpea flour.) I discovered that they all work well as long as you have a base of white rice flour, plus a high-fiber flour. You can also do 100% white rice flour for a lighter muffin, but for those of you who, like me, need to hibernate immediately, hearty is good.

I also tested out dairy and non-dairy versions: buttermilk, greek yogurt, and soy milk.


In all, I made enough muffins to feed the city, and when I was just about to start the dairy testing, but realized I had no more puree left, I picked out a recipe for the January monthly muffin (shhhh, it’s a secret. duh.) The texture of these muffins is so unbelievable, you’d never guess they’re gluten-free. None of the weird gummy-crumbly-heavy-like-a-boulder stuff, and you don’t have to break the bank searching for flours you’ve never heard of (but if you would like to do so, by all means, go ahead.) When it came to non-dairy milk, I decided just to try a totally vegan version, and those turned out as well as the rest, albeit a little smaller and drier.

All substitutions included in the recipe below.



gluten-free sweet potato ginger muffins (with vegan substitutions below)

adapted from whole wheat pumpkin streusel muffins

makes 1 dozen


80 g (2.8 oz) white rice flour

80 g  (2.8 oz) high-fiber gluten-free flour (brown rice, soy, chickpea, buckwheat) or 80 g white rice flour (160 g total)

80 g (2.8 oz) starch (tapioca and cornstarch combined, or one of the two)

1 tsp salt

1 tsp baking soda

1 tsp baking powder

1 tsp ground cinnamon

1 tsp ground ginger

80 g (2.8 oz) buttermilk*

150 g (5.3 oz) maple syrup or agave nectar

2 eggs**

45 g (1.6 oz) canola oil

200 g (7 oz) sweet potato puree

1 c crystallized ginger


*You can substitute greek yogurt, milk (dairy or non-dairy), or dried buttermilk. For greek yogurt, the batter will be thicker, so add a few extra grams of yogurt (90-100 g), and for milk, substitute 1:1 (80 g.) If you use dried buttermilk: 80 g water into the wet mixture and 4 teaspoons of buttermilk powder into the dry.

**You can make these vegan by using 80 g non-dairy milk and 20 g vinegar in the wet mixture, and 3 tsp baking soda (10 g vinegar + 1 tsp baking soda = 1 egg), instead of 1 tsp in the dry mixture. These will be a little drier than the recipe, so I would do 160 – 170 g syrup instead of 150.


Preheat oven to 350 F/175 C and line a muffin tin with 12 paper cups.

In a small bowl, combine the flours, starch, salt, baking soda and powder, and spices.

In a large bowl, whisk together syrup, buttermilk, canola oil, eggs, and puree.

Dump dry mix into wet and mix quickly. If desired, mix in extras (nuts, raisins, etc.) and divide evenly among muffin cups, ~3 Tbsp per cup, then top with streusel, nuts, cinnamon brown sugar, or whatever else you like.

Bake for 20 – 25 minutes until firm to the touch and a wooden toothpick inserted in the center comes out clean.

Remove from the oven and let cool in pan, then transfer to a wire rack to continue cooling.


I like them best when they’re topped with cinnamon and brown sugar.

Happy Muffin-days,

Nick P.
