These Vegan and Gluten Superfood Longevity Muffins have become my go-to treat when I want something nourishing but just as satisfying as a bakery classic. Packed with purple sweet potato and bursting with blueberries these muffins are not your average snack. They are perfect for meal prep or a midday energy boost while being allergy friendly for gatherings and family breakfasts.
These muffins first won me over when I baked them for a weekend brunch with friends. The texture was so tender and the color so vibrant that everyone went back for seconds.
Ingredients
- Purple sweet potato: this superfood root gives your muffins gorgeous color and natural antioxidants For best flavor and smoothest texture mash well in a food processor with dairy free milk until creamy
- Gluten free oat flour: gives structure and keeps the muffins hearty Use fine oat flour for a light crumb
- Arrowroot powder: acts as a binder and helps create a fluffy texture You can use tapioca or corn starch in a pinch Look for a pure white powder without clumping
- Maple syrup: provides natural sweetness and gentle moisture Use grade A dark for a deeper flavor
- Baking powder: ensures the muffins rise to a lovely dome Look for aluminum free for a clean aftertaste
- Cinnamon: adds warmth and subtle spice Choose fresh ground for best result
- Vanilla extract: rounds out the flavors with a hint of floral sweetness Go for pure vanilla not imitation
- Dairy free yogurt: keeps everything tender and moist Unsweetened yogurt is best to keep the muffins from turning out too sweet
- Egg replacer: supports the structure without using real eggs Mix well with water for best effect Bob’s Red Mill is my favorite for consistent result
- Blueberries: burst with sweetness in every bite Coat lightly with arrowroot to keep them suspended in the batter Fresh berries work best for flavor and texture
Step-by-Step Instructions
- Prepare the Sweet Potato:
- Start by boiling purple sweet potato until very soft Cool slightly then blend with about one fourth cup of dairy free milk in a food processor Process until silky and free from lumps This method gives your muffins vivid color and extra moisture
- Mix the Wet and Dry Ingredients:
- In a large mixing bowl combine the creamy mashed sweet potato oat flour arrowroot powder maple syrup baking powder cinnamon vanilla extract dairy free yogurt and egg replacer mixture Stir thoroughly until the batter is smooth and all the flour is moistened
- Incorporate the Blueberries:
- Sprinkle one tablespoon of arrowroot powder over the blueberries and toss gently to coat Fold the berries into the batter very carefully This prevents staining and keeps berries suspended
- Fill the Muffin Tin:
- Prepare your muffin tin with liners or a light coat of oil Spoon the batter evenly into each muffin cup filling all the way to the top Gently press a few extra berries onto the tops for a pretty look
- Bake the Muffins:
- Place the muffin tin in a preheated oven at three hundred fifty degrees Fahrenheit Bake for about twenty eight minutes The muffins should look puffed and feel springy on top A toothpick inserted should come out clean
- Cool and Serve:
- Remove the muffin tin from the oven and let the muffins rest for about ten minutes on the counter Lift the muffins onto a wire rack to cool fully before eating This helps the structure set and prevents soggy bottoms

Purple sweet potato has become a staple in my kitchen since I discovered how it brings brilliant color and hidden nutrients into recipes like these muffins My daughter always asks for the purple muffins whenever she sees them and I love watching her enjoy every crumb
Storage Tips
Store the cooled muffins in an airtight container at room temperature for up to two days or refrigerate for up to six days The texture stays soft thanks to the sweet potato but keep in mind they are most tender at room temperature To freeze wrap muffins individually then place in a freezer bag and thaw overnight on the counter or toast briefly before serving
Ingredient Swaps to Try
No oat flour on hand Try sorghum or brown rice flour instead Just keep the ratio the same Tapioca or corn starch will sub just fine for arrowroot If blueberries are not available frozen berries can work but do not thaw and roll them in arrowroot before using
Serving Suggestions
I love enjoying these muffins warm with a little almond or cashew butter and extra maple syrup They make the perfect breakfast with hot coffee or can be sliced in half and filled with fruit preserves for a lunchbox treat The color and fruity aroma also makes them a standout for brunch tables
