Ingredients in Blackberry Cinnamon Swirl Oatmeal Muffins

Rolled Oats: Gives the muffins a hearty, slightly nutty texture and keeps them extra moist.

All-Purpose Flour: Forms the base for a soft, tender crumb.

Baking Powder & Baking Soda: For a perfect rise and light, fluffy texture.

Salt: Balances the sweetness and enhances all the flavors.

Cinnamon: Warm and comforting—used in both the batter and the swirl.

Eggs: Help bind the muffins and give them structure.

Milk (or Buttermilk): Keeps everything tender and helps the oats soften.

Oil or Melted Butter: Adds richness and moisture.

Brown Sugar: Sweetens the muffins and plays beautifully with the cinnamon.

Vanilla Extract: A must for that cozy, bakery-style flavor.

Blackberries: Fresh or frozen work beautifully. Juicy, tart, and totally delicious.

Cinnamon Sugar (for Swirl): A simple mix of cinnamon and sugar that creates that beautiful layered effect.

Instructions

Preheat Your Equipment: Preheat your oven to 375°F and line a muffin tin with paper liners or lightly grease it.

Combine Ingredients: In a large bowl, mix oats, flour, baking powder, baking soda, salt, and cinnamon. In another bowl, whisk together eggs, milk, brown sugar, vanilla, and oil or melted butter.

Prepare Your Cooking Vessel: Set out your muffin tin and make sure it’s ready to go.

Assemble the Dish: Pour the wet ingredients into the dry and stir until just combined. Gently fold in the blackberries (don’t overmix—they’ll break apart a bit, and that’s okay!).

Cinnamon Swirl Time: Fill each muffin cup halfway, sprinkle a bit of cinnamon sugar in the center, then top with more batter and a little more cinnamon sugar on top. Use a toothpick or knife to gently swirl if desired.

Cook to Perfection: Bake for 18–22 minutes, or until a toothpick comes out clean and the tops are golden and domed.

Finishing Touches: Let the muffins cool in the pan for a few minutes before transferring to a wire rack to cool completely.

Serve and Enjoy: Enjoy warm, room temp, or even chilled—they’re delicious any way you slice it.
