Note from Sabrina
If you’re aiming for a chewier brownie base, a few simple ingredient swaps can make all the difference. Combining oil and butter instead of using just one creates a moist texture that enhances chewiness. For the best results, try using ¼ cup of butter and ¼ cup of oil. Additionally, using both white and brown sugar is key. The brown sugar retains more moisture than white sugar, contributing to a fudgier, chewier brownie. Substituting 1 cup of white sugar paired with 1 cup of brown sugar. These adjustments will elevate your brownies to a delightful chewy texture!

About this Recipe
Oatmeal Chip Brownies are made with easy ingredients you probably have in your pantry. Sugar, vanilla, butter, eggs, cocoa powder, and a few other staples are all you need to toss it together. So, it’s perfect if you need to whip up a dessert at the last minute for a potluck or bake sale!
Can this be made ahead of time?
Absolutely, you can definitely prepare these brownies ahead of time! To ensure they stay fresh, store them in an airtight container in the refrigerator, where they’ll last for up to a week. If you want to keep them for an even longer period, freezing is a great option. Simply separate the brownies with parchment paper to prevent them from sticking together, then place them in an airtight container or a heavy-duty freezer bag. They can be frozen for up to six months without losing their flavor or texture. When you’re ready to enjoy them, just thaw the brownies in the fridge overnight before serving. This method helps maintain their moistness and ensures they’re perfect for your enjoyment.
How to Store
- Serve: Once the Oatmeal Chip Brownies have cooled, you can cover them in plastic wrap to keep at room temperature for up to 4 days.
- Store: To keep leftovers in the fridge, cover them, or slice them into squares and put them in an airtight container. They’ll stay good for up to a week.
- Freeze: To keep brownies for up to 6 months, put them in a freezer bag separated by parchment paper and freeze.
Serving Ideas
These brownies are awesome when you pair them with a tall glass of cold milk. Seriously, the chocolatey goodness just hits different! If you want to take it up a notch, throw in a scoop of Vanilla Ice Cream. The warm brownie and cold ice cream combo is pure magic! Drizzle some Chocolate or Caramel sauce on top, and you’ve got yourself a dessert that’s hard to beat. Enjoy!
Variations
- Mix-ins: You can try a variety of different mix-ins in the oatmeal dough instead of chocolate chips. Raisins, M&Ms, chopped nuts, toffee bits, and butterscotch chips would all taste great.
- Peanut Butter Oatmeal Brownies: To make Peanut Butter Oatmeal Brownies add the peanut butter before the oat mixture. Prepare the brownie batter as usual, then add melted peanut butter to the top. Use an offset butter knife to swirl the peanut butter in. Add the oats over the top and bake the Peanut Butter Oatmeal Brownies.
- Flour: For a healthy spin on your Oatmeal Chip Brownies, you can use whole wheat flour instead of white flour. If you want gluten-free brownies, use oat flour, almond flour, or coconut flour.
- Sweetener: You can also substitute the granulated sugar in the brownies for other sweeteners like honey, maple syrup, or coconut sugar.
- Brownie Base: Take the recipe for the oat topping and put it over my Walnut Brownies, Peanut Butter Chip Brownies, or Monster Brownies. It’s the best way to add a unique flavor, texture, and some fiber to any of your favorite brownies.

I love the idea of adding a peanut butter swirl like you mentioned in the variations. If I do that, should I bake them for a few extra minutes since the peanut butter adds extra moisture, or does the standard 35-40 minutes still work?
