Aren’t they gorgeous?

Is it just me, or do these blackberry muffins look almost too pretty to eat? I knew the blackberries would pop, but I didn’t expect to love how they turned out this much. These are the kind of muffins you’d feel good about sharing — the perfect just had a baby gift, oh it’s your birthday gift, or a just because I love you muffins gift.

I make muffins because they’re easy, versatile, and forgiving. Oh — and because my family actually eats them. My kids especially love muffins, and these are no exception. They’ll happily devour these sour cream blueberry muffins and my Nutella muffins without hesitation. I mean, Nutella is basically a guaranteed win if you want your kid to eat something… just saying.

These blackberry oatmeal muffins come together quickly and bake up fluffy and flavorful. The key step here is soaking the oats before baking. It might seem skippable, but don’t do it. Soaking the oats in buttermilk softens them so they bake right into the muffin instead of staying chewy. It only takes 10 minutes and makes a huge difference in texture. Just do it.

Now let’s talk about the crumb topping. Please don’t skip this step. Crumb-topped muffins — like these pumpkin streusel muffins — are simply better. This easy extra step takes muffins from an 8 to a 10, and it adds texture, which is always a good thing when it comes to food. Other than that, the recipe is very straightforward. Let’s dive into the steps.

Ingredients

Blackberry Muffins:

  • 1 cup old-fashioned rolled oats
  • 1 cup buttermilk (or whole milk + 1 tablespoon lemon juice, let sit for 5 minutes)
  • 1 cup all purpose flour
  • 1/2 cup brown sugar (light or dark)
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon
  • 1 large egg, room temperature
  • 1/3 cup melted butter (or neutral oil)
  • 1 1/2 teaspoons pure vanilla extract
  • 6 ounces fresh blackberries, sliced in half (frozen work, too. Do not thaw or slice)

Crumb Topping:

  • 1/2 cup all purpose flour
  • 1/4 cup rolled oats
  • 1/4 cup brown sugar (light or dark)
  • 1/4 teaspoon cinnamon
  • 5 tablespoons room temperature butter

Instructions

    1. Prep: Preheat oven to 400 degrees F. Line a muffin pan with liners or spray well with nonstick baking spray. Set aside.
    2. Soak the oats: In a medium bowl, combine the oats and buttermilk. Let sit for 10 minutes to soften.
    3.) Make the crumb topping: Add flour, oats, brown sugar, and cinnamon to a small bowl and mix. Cut in the butter using your fingers until combined and crumbly.
    4.) Combine dry ingredients for the muffin batter: In a separate bowl, whisk together the flour, brown sugar, baking powder, baking soda, salt and cinnamon. Set aside.
    5.) Combine wet ingredients: To the oat mixture, add the egg, melted butter and vanilla. Stir until smooth.
    6.) Bring it all together: Add the dry ingredients to the wet and gently fold together with a spatula just until combined - do not over-mix. Lumpy batter is okay! Over-mixing can cause dense/tough muffins. Carefully fold in the blackberries. Let rest for 10 minutes.
    7.) Fill the muffin tin: Divide the batter evenly between muffin cups using a large cookie dough scoop if you have one. They will be fairly full. Sprinkle each with a generous amount of crumb topping.
    8.) Bake and cool: Bake at 400 degrees for 5 minutes then reduce the heat and and bake for additional 14-16 minutes (mine backed for 15 minutes) or until a toothpick inserted in the center of a muffin comes out clean. Let muffins cool for 5 minutes in the pan then remove to cool completely.

Notes

Storage: Store in an airtight container at room temperature for 3 days. Muffins can be stored up to a week in the refrigerator.

Freezing: Muffins can be frozen for up to to 2 months. Thaw overnight at room temperature.
