November brings the scent of cinnamon and nutmeg, cozy sweaters and the urge to bake — but many of us also want to avoid overdoing the sugar and calories. These Spiced Sweet Potato Blender Muffins with Pecan Streusel are a perfect seasonal solution: they deliver moist, tender crumb and warm holiday spices with less sugar, thanks to a baking blend that combines raw sugar and stevia. They feel indulgent without being overly sweet, and the crunchy pecan streusel gives each muffin a festive finish.
Made in a blender, this muffin batter is especially easy and consistent. Using cooked sweet potato adds natural moisture and body, while oats and a bit of flour keep the texture substantial but soft. Cinnamon, nutmeg, and cardamom bring classic autumn flavor, and the streusel—made with oats, chopped pecans, flour and a touch of sweetener—adds contrast in both texture and flavor. These muffins are ideal for holiday breakfasts, brunches, or a portable snack to enjoy with coffee or tea.
The blender method makes this recipe fast: you simply combine the cooked sweet potato with eggs, buttermilk, oats, flour and leavening in the blender and process until smooth. The batter is relatively thick because of the sweet potato, so scraping the sides and pulsing a few times helps ensure everything is fully combined. If you prefer, you can also fold the dry ingredients by hand, though the blender guarantees a perfectly mixed batter with minimal effort.
Because this recipe uses a baking blend that blends raw sugar and stevia, you can use less sweetener while maintaining a pleasant sweetness without an aftertaste. The result is a muffin that tastes like a treat but won’t overwhelm your day with added sugar. If you don’t have a baking blend, regular granulated sugar can be used in the amounts noted in the ingredient list.

Ingredients
For the Muffins:
- 1 large sweet potato
- 2 large eggs
- ½ cup buttermilk
- 1 ½ cups all-purpose flour
- ½ cup oats
- ¼ cup Whole Earth Sweetener Baking Blend (or ½ cup sugar)
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- ½ teaspoon salt
- 1 teaspoon cinnamon
- ½ teaspoon nutmeg
- ½ teaspoon cardamom
For the Pecan Streusel:
- ½ cup oats
- ½ cup chopped pecans
- ¼ cup all-purpose flour
- 2 tablespoons Whole Earth Sweetener Baking Blend (or ¼ cup sugar)
- 4 tablespoons melted butter
Instructions
- Use a sharp knife to score the sweet potato and microwave on high for about 10 minutes, or until soft. Allow to cool slightly, then scoop out the flesh and discard the skin.
- Preheat the oven to 375ºF (190ºC) and line a standard 12-cup muffin tin with paper liners.
- Add 1 cup of the cooked sweet potato, eggs, buttermilk, flour, oats, baking blend (or sugar), baking soda, baking powder, salt, and spices to a blender or food processor in the order listed. Cover and blend on high for 2–3 minutes, scraping down the sides as needed, until the batter is smooth and fully incorporated.
- Divide the batter evenly among the prepared muffin cups.
- In a small bowl, combine oats, chopped pecans, flour, sweetener, and melted butter. Mix until the streusel resembles coarse, wet sand. Spoon the topping over each muffin, pressing lightly so it adheres.
- Bake for 21–23 minutes, or until muffins are golden and a toothpick inserted in the center comes out clean. Remove from the oven and cool completely before serving.

Notes, Variations and Tips
Storage: Store cooled muffins in an airtight container at room temperature for up to 2 days. For longer storage, freeze muffins in a sealed bag for up to 3 months; thaw overnight in the refrigerator or warm briefly in the microwave.
Make-ahead: You can prepare the sweet potato ahead of time and refrigerate it for up to 3 days. Measure and store dry streusel ingredients separately and combine with melted butter just before topping the muffins.
Substitutions: If you don’t have buttermilk, mix ½ cup milk with 1 teaspoon vinegar or lemon juice and let sit for 5 minutes. Use gluten-free all-purpose flour and certified gluten-free oats to make these muffins gluten-free. Swap pecans for walnuts, or omit nuts for a nut-free streusel.
Texture and flavor tips: For a smoother batter, make sure the sweet potato is fully cooked and scooped to remove any stringy pieces. Adjust the spices to taste — add more cinnamon for a bolder profile or a pinch of ginger for extra warmth. If you prefer a crumb topping with more crunch, toast the pecans lightly before chopping.
Serving suggestions: These muffins are delicious warm with a smear of butter or cream cheese, alongside coffee or a cup of chai. They also travel well for packed breakfasts and holiday brunch spreads.
