Ingredients

Sweet potato oatmeal muffin ingredients displayed neatly for easy meal prep baking.
  • Sweet Potato: Fresh sweet potatoes microwaved for a few minutes until fork-tender work best. They add moisture, flavor, and natural sweetness to the muffins. You can also substitute canned sweet potato purée—or even pumpkin—for an easy, slightly different twist.
  • Egg: Helps the muffins rise and hold together. Substitute 1 tbsp chia seeds mixed with 3 tbsp water for a egg-free option.
  • Greek Yogurt: Adds creaminess and protein. Substitute low-fat Greek yogurt, Skyr for even more protein, or a thick dairy-free yogurt.
  • Milk: Any dairy or non-dairy milk works.
  • Maple Syrup: Adds natural sweetness and moisture. Swap with honey or agave syrup for a similar flavor, or use regular sugar—about ½ cup for a mildly sweet muffin or up to 1 cup if you want something closer to a dessert-style treat.
  • Vanilla Extract: Adds warmth. Almond extract also works for a bakery-style flavor.
  • Rolled Oats: Bring texture and fiber. Substitute quick oats if needed, or a gluten-free oat option for a similar oatmeal muffins without oil.
  • Flour: All-purpose gives the best texture. Substitute white whole wheat flour for a heartier muffin or a 1:1 gluten-free blend.
  • Baking Powder + Baking Soda: Essential for lift. No substitution recommended.
  • Cinnamon: Adds warmth. Chai spice or apple pie spice also taste wonderful in our oil free muffin recipes.

How to Make Healthy Sweet Potato Oatmeal Muffins

Step 1. Prepare the Sweet Potatoes

Preheat your oven to 375°F / 190°C. Pierce each sweet potato with a fork and microwave for 7–10 minutes, or until fork tender. Cut them open carefully (they’re hot!), scoop out the flesh, and mash until smooth. You’ll need about 1.5 to 2 cups. This step gives your muffins that soft, naturally sweet texture you expect from great sweet potato oat muffins.

Step 1 Mashed sweet potatoes in a bowl ready for baking sweet potato oat muffins.

Step 2. Mix the Wet Ingredients

Add the mashed sweet potato to a large bowl. Whisk in the egg, Greek yogurt, milk, maple syrup, and vanilla. Whisk until the batter looks smooth and creamy with no lumps of yogurt left.

Step 2 Smooth wet ingredients mixed together for healthy sweet potato oatmeal muffins.

Step 3. Add the Dry Ingredients

Sprinkle in the rolled oats, flour, baking powder, baking soda, cinnamon, and salt. Stir gently until everything comes together. Try not to overmix—this keeps these meal prep breakfast muffins soft and tender.

Step 3 Dry ingredients added to bowl creating thick muffin batter with oats and sweet potato.

Step 4. Fill the Muffin Pan

Line a muffin tray with paper liners. Spoon the batter evenly into the 12 cups, filling each one almost to the top. The batter will be thick, and that’s exactly right.

Step 4 Muffin batter spooned into lined tray ready for baking.

Step 5. Bake the Muffins

Bake for 22 minutes, or until the tops are set and a toothpick inserted in the center comes out mostly clean. Let them rest in the pan for 5 minutes.

Move the muffins to a wire rack to cool completely. Once cool, they peel easily from the liners and stay soft, moist, and perfect for breakfast or snacks all week.

Tips

  • Lightly spray your muffin liners: A tiny spritz of oil spray makes it much easier to peel these healthy oatmeal breakfast muffins once they’re cool.
  • Mash the sweet potatoes until completely smooth: Any lumps will affect the texture. A smooth mash makes these high fiber breakfast muffins soft, tender, and evenly sweet.
  • Don’t overmix the batter: Stir just until the dry ingredients disappear. Overmixing can make the muffins dense instead of fluffy.
  • Let the muffins cool fully: They set as they cool. If you try to peel them too early, they may stick.
  • Check your muffins early: Every oven is different. Start checking this sweet potato muffin recipe at the 20-minute mark to avoid overbaking, especially if you prefer softer textures.
  • Add mix-ins carefully: If you like raisins, nuts, or chocolate chips, fold them in gently at the end so the batter stays fluffy.
  • Use thick yogurt: Regular yogurt can make the batter too wet. Greek yogurt or Skyr gives you better structure.
