Gathering Your Brownie Ingredients

This is where the magic starts. You probably have most of this hanging out in your pantry already

Print

• 1 ½ cups oat flour (make sure it’s certified gluten-free if needed)
• ¾ cup unsweetened cocoa powder
• 1 cup granulated sugar
• ½ cup packed brown sugar
• ½ teaspoon salt
• ½ teaspoon baking powder
• 2 large eggs, at room temperature
• ½ cup melted coconut oil (or neutral oil like avocado)
• ⅓ cup water or cooled coffee (coffee makes the chocolate flavor pop!)
• 1 teaspoon vanilla extract
• ¾ cup chocolate chips, plus more for sprinkling on top

How to Make Your Gluten-Free Brownies

Let’s get down to business! This process is so straightforward, you barely need me to guide you.

1. Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal. This is my best tip for perfect brownie squares!
2. In a large bowl, whisk together the oat flour, cocoa powder, granulated sugar, brown sugar, salt, and baking powder. Make sure there are no lumps.
3. Add the eggs, melted oil, water (or coffee), and vanilla extract to the dry ingredients. Stir with a spatula until you have a thick, glossy batter. Try not to overmix—just until everything is combined.
4. Fold in the chocolate chips, saving a few to sprinkle on top because we eat with our eyes first.
5. Pour the batter into your prepared pan and spread it into an even layer. Top with the reserved chocolate chips.
6. Bake for 25-30 minutes. You’ll know they’re done when the top is set and shiny, and a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).
7. This is the hardest part: let them cool completely in the pan before slicing. I know, the wait is torture, but it’s what gives you those clean, beautiful slices.

Tips, Tricks, and Delicious Variations

I’ve made these brownies more times than I can count, and here’s everything I’ve learned along the way.

• Make Your Own Oat Flour: It’s so easy! Simply add old-fashioned or quick oats to a high-powered blender or food processor and blitz until it looks like a fine powder. One cup of oats yields about one cup of flour.
• Don’t Overbake: The key to that fudgy texture is pulling them out of the oven when they’re just set. They will continue to set up as they cool.
• Add-Ins Galore: Feel free to stir in a handful of walnuts, pecans, or even a swirl of peanut butter before baking.
• Storage: Keep these gluten-free dessert bars in an airtight container at room temperature for up to 4 days. They also freeze beautifully for up to 3 months.

How to Serve These Decadent Bars

While they are absolutely sublime all on their own, a little flair never hurt anybody. I love serving a warm square with a scoop of vanilla ice cream melting over the top. For a true dessert experience, drizzle them with a little easy homemade caramel sauce.

Your Oat Flour Brownie Questions, Answered

Can I use a different type of flour?

This recipe was specifically developed for oat flour, which gives it that signature fudgy yet sturdy texture. I don’t recommend substituting it with almond or coconut flour, as they behave very differently and would require a complete recipe overhaul.

How do I know when the brownies are done baking?

Look for a set top with that classic crackly surface. The most reliable test is the toothpick test: a few moist crumbs clinging to the toothpick is perfect. If it comes out clean, they might be a tad overbaked and more on the cakey side.

Can I make these dairy-free as well?

Absolutely! These brownies are naturally dairy-free if you use dairy-free chocolate chips. Always check the labels on your chocolate chips to be sure.

Why did my brownies turn out cakey?

A cakey texture usually means the batter was overmixed or the brownies were left in the oven a minute or two too long. Remember, we’re going for a stir-until-just-combined technique for that dense, fudgy result.
