How to Make It

1. Preheat and prep: Heat the oven to 375°F (190°C). Line a 12-cup muffin tin with liners or lightly grease each cup.
2. Soak the raisins: Place raisins in a small bowl and cover with hot water.

   Let sit 10 minutes to plump, then drain and pat dry.

3. Hydrate the oats: In a large bowl, combine 1 cup rolled oats with 1 cup milk. Let sit 10 minutes to soften. This prevents dry, crumbly muffins.
4. Mix dry ingredients: In a separate bowl, whisk 1/2 cup wheat bran, 3/4 cup whole-wheat flour, 3/4 cup all-purpose flour, 1 1/2 teaspoons baking powder, 1/2 teaspoon baking soda, 1/2 teaspoon salt, and 1–2 teaspoons cinnamon.
5. Whisk wet ingredients: To the oat-milk bowl, add 1/2 cup Greek yogurt, 2 large eggs, 1/3 cup neutral oil, 1/3 cup brown sugar, 2 tablespoons honey or maple syrup (optional), and 2 teaspoons vanilla.

   Whisk until smooth.

6. Combine gently: Add the dry mixture to the wet mixture. Stir with a spatula just until a few dry streaks remain. Fold in the drained raisins (and 1/2 cup chopped nuts if you like).

   Do not overmix.

7. Fill the pan: Divide batter evenly among muffin cups, filling each about 3/4 full. Sprinkle a few extra oats on top for a bakery-style look.
8. Bake: Bake 16–20 minutes, or until the tops spring back and a toothpick comes out clean or with a few moist crumbs.
9. Cool: Let muffins rest in the pan 5 minutes, then transfer to a wire rack. Cool at least 10 minutes before serving.

How to Store

• Room temperature: Store in an airtight container for up to 2 days.

  Place a paper towel in the container to absorb moisture.

• Refrigerator: Keep up to 5 days. Warm briefly in the microwave or toaster oven to revive the crumb.
• Freezer: Freeze up to 3 months. Wrap individually, then place in a freezer bag.

  Thaw overnight in the fridge or reheat from frozen at 300°F (150°C) for 10–12 minutes.

Why This is Good for You

• Fiber for fullness: Oats, wheat bran, and whole-wheat flour bring both soluble and insoluble fiber, which can support digestion and help keep you satisfied.
• Steady energy: The mix of complex carbs and protein from Greek yogurt helps prevent blood sugar spikes and mid-morning crashes.
• Heart-friendly ingredients: Oats contain beta-glucan, a soluble fiber linked to healthy cholesterol levels.
• Less sugar than typical muffins: Brown sugar is kept moderate, and raisins add natural sweetness, so you get flavor without a sugar bomb.

Common Mistakes to Avoid

• Overmixing the batter: This leads to tough muffins. Stir just until combined and stop.
• Skipping the oat soak: Dry oats can pull moisture from the batter during baking, making the muffins crumbly.
• Not plumping the raisins: Rehydrated raisins are juicier and won’t burn on top.
• Overbaking: Check a few minutes early. When in doubt, remove them slightly under rather than over; they continue to set as they cool.
• Using only whole-wheat flour: A mix of whole-wheat and all-purpose yields a lighter, more tender crumb.

Recipe Variations

• Nutty crunch: Fold in 1/2 cup chopped walnuts or pecans.

  Toast them first for extra flavor.

• Citrus twist: Add 1 teaspoon orange zest to brighten the raisins and cinnamon.
• Extra fiber boost: Stir in 1–2 tablespoons ground flaxseed or chia seeds.
• Apple cinnamon: Fold in 3/4 cup finely diced apple and a pinch of nutmeg. Reduce raisins to 1/2 cup if desired.
• Lower sugar: Cut brown sugar to 1/4 cup and skip the honey. Increase vanilla to 1 tablespoon for flavor.
• Dairy-free: Use plant milk and dairy-free yogurt, and choose oil instead of butter.

  The texture stays moist.

• Gluten-friendly approach: Swap the flours with a 1:1 gluten-free blend and use certified gluten-free oats and oat bran. Texture will be slightly more delicate.

FAQ

Can I use quick oats instead of rolled oats?

Quick oats will work in a pinch, but the texture will be softer and a bit less hearty. If you use them, reduce the soak time to 5 minutes so they don’t get mushy.

How do I keep muffins from sticking to the liners?

Use high-quality parchment liners or lightly grease the liners.

Let muffins cool 5–10 minutes before removing; yanking them out piping hot can cause sticking.

Can I replace the raisins with something else?

Yes. Try chopped dates, dried cranberries, or chopped dried apricots. Keep the amounts similar, and still soak them for the best texture.

Why did my muffins turn out dense?

Most likely overmixing, too much flour, or old leaveners.

Spoon flour into the measuring cup and level it, and make sure your baking powder and soda are fresh.

Can I make these muffins without eggs?

Yes. Use two flax “eggs” (2 tablespoons ground flaxseed + 5 tablespoons water, rested 5 minutes). The muffins will be slightly denser but still tasty.

How can I make them sweeter?

Add 2–3 tablespoons more brown sugar or stir in a handful of mini chocolate chips.

You can also finish the tops with a light sprinkle of turbinado sugar for crunch.

What’s the best way to reheat?

Warm in a 300°F (150°C) oven for 6–8 minutes or microwave for 15–20 seconds. A quick reheat brings back the softness and wakes up the spices.
