Sugar-Free Sweet Potato Bread


Sweet Potatoes, how do I love thee; luscious, moist, flavorful, low glycemic, packed with vitamins and fiber - sweet! So, it naturally followed that I should develop some new, recipes using this wonder food. This is very, very good; moist and rich tasting.


1 1/4 cup/12 ounces cooked sweet potato, mashed
1/2 cup water
1 large egg
1 extra large egg
1 1/2 tsp vanilla extract OR 1 TB bourbon
2 cups whole wheat pastry flour, (minus 4 TB)
2-3 TB flax meal (optional)
1 TB soy protein (optional)
1 TB whey powder (optional)
1/3 cup xylitol
4 1/2 tiny scoops stevia
3 TB +1 tsp erythritol ("Zero")
1 tsp salt
1 tsp baking soda
1 1/2 tsp cinnamon
1/4 tsp ground cloves
1/2 cup coarsely chopped pecans

If you don't have access to erythritol, raise the xylitol to a scant 1/2 cup.

If sugar is not a problem for you, substitute 3/4 cup of sugar for all of the sweeteners.

Preheat the oven to 350F. Grease a loaf pan. In a large bowl, mash the sweet potatoes well with a potato masher, and whisk in the water. Then stir in the eggs and vanilla or bourbon until well blended.

If you are using the supplemental proteins and flax powder, measure the 2-3 TB of flax meal, 1 TB of soy protein, and 1 TB of whey powder, then fill the rest of the measure with the whole wheat pastry flour. In a medium sized bowl, add this, plus the second cup of flour, the baking soda, the salt, the spices, and all of the sweeteners, and whisk the ingredients to blend.

Add the dry ingredients to the wet and stir well. Add the nuts and blend. Spoon into the loaf pan, using a spatula to get all of the batter, and bake for about an hour. Run a butter knife around the edges of the pan to loosen the loaf, then cool on a rack. This is quite delicious toasted, served with sweet butter or toasted nut butters.

Notes from Christine: You may have a bunch of questions as to why I've given the substitutions I have. Why whole wheat pastry flour? Pastry flour is lower in gluten than regular flour, so it makes a less dense bread. This way you get the whole grains and the reduced carbohydrates, but without the heaviness. Why one extra large egg? When I have made similar breads before using 100% whole wheat, it didn't rise as much as it did with all unbleached refined flour, or 50/50. When I baked this version, I happened to have one extra large egg and one large egg on hand, and this is what I used. Voila; it rose to perky heights! Why the flax meal? Flax meal is full of omega 3 fatty acids, which actively convert "bad" cholesterol into "good" cholesterol in your body. Here is a lovely way to sneak them into something yummy. Also, if you are cutting carbs, this substitutes a lower carb ingredient. Why the xylitol, stevia and erythritol? As I have written in previous posts, stevia is a calorie-free, completely natural sweetener extracted from stevia leaves. However, it has a funky aftertaste. Therefore, it is best to mix it with another sweetener. Xylitol is a sugar alcohol, which the body metabolizes differently than sugar. It is 40% lower in calories, and metabolized 75% more slowly than cane sugar. I like those numbers! Plus, it is actually good for your teeth. However, it is extracted in weird and yucky ways from wood, so I'm not thrilled. Erythritol (marketed as Wholesome Sweeteners Zero) is my new darling; it is available made from organic sugar which has been fermented, with zero calories and zero on the glycemic index - wow! But, it is only 60% as sweet as sugar, and is wickedly expensive. So, ta da! Mix them together!

Whey powder is available from well-stocked grocery and natural food stores. Berkeley Bowl carries whey powder and flax meal in a refrigerated case near the bulk food section.
