Oatmeal Chocolate Chip Muffins are a simple, feel-good baking recipe made with just a few basic ingredients. They’re soft and tender with a touch of cinnamon and plenty of melty chocolate chips in every bite.

These muffins remind me of the kind of snack I’d reach for mid-morning or add to my weekday lunches. I love how the oats give them heartiness without making them heavy. When they’re fresh and warm from the oven with a bit of butter, they never last long!
Love the texture and flavor oats bring to baked goods? You might enjoy these other favorites too! Gluten-free oatmeal cream pies, blackberry oatmeal muffins, and these copycat Starbucks oatmeal bars are just a few to try next!

Ingredients

- Rolled Oats: Old-fashioned rolled oats give the muffins a hearty bite. Avoid quick oats, which can make the texture mushy.
- Granulated Sugar & Brown Sugar: The mix of white and brown sugars provides sweetness and a hint of moisture and richness from the molasses in the brown sugar.
- Milk: Use any milk you like. Oat, almond, or dairy all work here.
- Apple Cider Vinegar: Combined with the milk to create a buttermilk effect, which gives the muffins a more tender crumb.
- Butter-Flavored Olive Oil: Costabile butter-flavored olive oil (use my code 15GOLDENGK on Amazon for 15% off) adds richness and moisture with a hint of buttery flavor.
- Chocolate Chips: Semi-sweet or dark chocolate chips melt into the muffins. Mini chips also work well if you want a more even chocolate distribution.
See the recipe card below for exact ingredient amounts, nutritional information, and detailed instructions.
Variations
- Make it dairy-free: Use a plant-based milk and opt for dairy-free chocolate chips to keep the muffins completely dairy-free.
- Swap in dried fruit: Replace some or all of the chocolate chips with raisins, chopped dates, or dried cranberries for a naturally sweet twist.
- Add chopped nuts: Fold in ¼ cup of walnuts or pecans for added crunch and a nutty depth that pairs well with the oats and chocolate.
- Mini muffins for snacks: Spoon the batter into a mini muffin tin and reduce the baking time to 10–12 minutes for bite-sized, lunchbox-ready treats.

How to Make Oatmeal Chocolate Chip Muffins
Before you start, preheat the oven to 350°F and lightly grease a silicone muffin pan. You also should combine the milk and vinegar in a small cup and set it aside, as well as whisk together the gluten-free flour, oats, salt, cinnamon, and baking soda in a medium bowl.

Step 1: Mix wet ingredients. Whisk together the sugar, brown sugar, egg, milk mixed with vinegar, vanilla extract, and olive oil until fully combined.

Step 2: Add dry ingredients. Pour the dry mixture of gluten-free flour, oats, baking soda, salt, and cinnamon into the wet ingredients. Stir gently until just combined, avoiding overmixing.

Step 3: Fold in chocolate chips. Bently fold the chocolate chips into the batter to distribute evenly.

Step 4: Fill muffin wells. Evenly spoon the batter into the 9 prepared muffin wells.

Step 5: Bake. Bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean.

Step 6: Cool muffins. Remove the muffins from the oven and transfer them to a wire rack to cool completely before serving. Pair with a vanilla protein smoothie for a quick on the go breakfast.
Expert Tips
- Use rolled oats, not instant: Rolled oats give the muffins a nice texture without becoming overly soft, unlike quick oats.
- Combine wet and dry ingredients gently: Mix just until combined to keep the muffins tender and avoid overworking the batter.
- Let milk and vinegar sit: Allowing the milk and vinegar mixture to sit for a few minutes creates a homemade buttermilk effect, adding moisture and tenderness.
- Distribute chocolate chips evenly: Fold in the chocolate chips gently and evenly to prevent them from sinking to the bottom during baking.
- Don’t overfill muffin cups: Fill each cup about two-thirds full to give the oat chocolate chip muffins room to rise without spilling over.
Storage Directions
- Storing: Leftover chocolate chip oatmeal muffins keep best in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to 5 days. These muffins are freezer-friendly. Let them cool completely, then store in a freezer-safe bag or container for up to 3 months. Thaw at room temperature or warm in the microwave before serving.
- Reheating: Warm muffins in the microwave on medium heat for 20-30 seconds to bring back softness without drying them out.
Muffins freeze great! So make a double batch or make these along with some blackberry oatmeal muffins and orange poppyseed muffins. They're great to grab when you need something quick and easy.

Oatmeal Chocolate Chip Muffins FAQs
Overmixing the batter can cause dense muffins. Stir just until the dry ingredients are combined with the wet to keep them tender.
Yes, melted butter or a neutral oil like canola or vegetable oil works well in place of olive oil.
You can substitute lemon juice or white vinegar in the same amount to react with the baking soda and help the muffins rise.
