How to make oat flour brownies:
This is an overview of the recipe with photos. Complete instructions are located on the recipe card below.
First, preheat the oven to 350 degrees F.
Line an 8x8 pan with parchment paper.
In a bowl, whisk coconut oil, water, eggs, cane sugar and vanilla extract.
Add oat flour, cacao powder and salt.
Use a rubber spatula to combine.
When the flour and cacao powder is almost all mixed in, fold in the chocolate chips.
Pour the brownie batter into the prepared pan. The batter will be thicker than boxed brownie batter.
Bake at 350 degrees for 20-22 minutes.
Once baked, add flaky sea salt if you would like.
Allow them to cool completely before slicing into 9 brownies.
Recipe pro-tips:
I suggest using store bought oat flour. It has the perfect flour consistency. It can be more difficult to achieve the same exact texture blending oats at home.
Properly measure flour by spooning the flour into the measuring cup. Then, level off the top of the cup with a knife. Do not place the measuring cup into the bag and scoop. You could end up with more flour than needed.
I don't recommend reducing the sugar in this recipe. It contributes to the texture.
Use an 8x8 baking pan for this recipe, not another size.
This brownie batter will be thicker than boxed brownie batter.
If you cut the brownies while they are warm, they can fall apart. Allow them to cool completely before slicing because they will firm as they cool!
Storage instructions:
Store oat brownies in an airtight container on the kitchen counter for 2-3 days.
Store oat brownies in an airtight container or freezer bag and freeze them for up to 3 months.

Can u make w almond flour
Hi Joan! I cannot guarantee the recipe with work as I haven't tried almond flour myself. You can make my No Bake Brownie Bitesas an alternative to this recipe!

What can you use instead of sugar, nektar, date syrup, honey?
I don't recommend subbing another sweetener. Wholesome Organic Cane Sugar is what gives the brownies their perfect texture.
