These gluten-free brownies are made with healthier ingredients that you can get at all grocery stores. And as an added bonus they are sweetened with bananas so there is no added sugar!
If you are celiac or have a gluten intolerance, make sure to buy certified gluten-free oat flour because oats are often cross contaminated with wheat.
Recipe ingredient substitutions
Banana substitutions: Instead of using mashed bananas, you can swap it out for peanut butter or any other nut or seed butter.
Egg substitutions: Instead of eggs, swap it out for egg substitutes such as flax, chia or gelatin eggs.
Coconut oil substitutions: Instead of melted coconut oil, you could also use regular melted butter or melted vegan butter. Alternatively, you can use any other cooking oil of choice such as light tasting olive oil or avocado oil.
Cacao powder substitutions: I used raw cacao powder, but you can also use unsweetened cocoa powder. Cocoa has undergone processing which removes some of the nutrient density of the cacao bean. But they both work great and taste very similar!
Oat flour substitutions: Instead of using just oat flour, you could use a mixture of oat flour and oatmeal/rolled oats. You could also use a mixture of oat flour and a gluten-free flour blend.
Baking powder substitutions: Instead of baking powder, swap it out for 1/4 teaspoon baking soda.
Vanilla extract substitutions: Instead of liquid vanilla extract, you can also use ground vanilla bean powder or vanilla bean paste.
Stevia substitutions: Instead of stevia powder, you can also use liquid stevia drops. Or you can use a small amount of another sugar-free alternative such as monk fruit, erythritol, or xylitol. If you are okay with a bit of sugar, you can also use coconut sugar, brown sugar, cane sugar etc.
Make your own oat flour: To make homemade oat flour, put your rolled oats into a food processor or high-speed blender and blend them on high until it turns into a fine flour.
Make these brownies sweeter: These healthy brownies are only sweetened with bananas and stevia, but if you’ve got a sweet tooth you can add a bit of additional coconut sugar, brown sugar, or white sugar. I wouldn’t suggest using liquid sweeteners such as pure maple syrup or honey because it may throw off the wet to dry ingredients ratio and you may not get the best results.
Add additional flavor: They are great on their own, but to snazz them up, you could also add dark chocolate chips (or dairy-free chocolate chips), walnuts, pecans, or espresso powder.
Make them less sweet: If you want to make these lower in sugar and carbs, you can swap the mashed bananas out for an equal amount of peanut butter, almond butter, cashew butter or other nut butters.
Make this recipe candida diet friendly: Swap out the bananas for almond butter or sunflower seed butter. Use 1/4 teaspoon of stevia powder instead of 1/8 teaspoon.
Make this recipe lower lectin: Swap out the oat flour for a grain free alternative such as almond flour, tiger nut flour, or cassava flour.
Make this recipe vegan: To make vegan brownies, omit the eggs and replace them with flax or chia eggs.
Make this recipe elimination diet friendly: Omit the eggs and replace them with flax, chia or gelatin eggs.
Make this recipe paleo/grain free: Instead of oat flour, swap it out for almond flour, tiger nut flour or cassava flour, or a combination of both. Or check out my cassava flour brownies recipe.
Pair these fudgy brownies with a scoop of ice cream, coconut whipped cream or even a scoop of peanut butter with sliced up banana.
Store your oat brownies in an airtight container in the fridge for up to 1 week, or in the freezer for up to 3 – 6 months. If you freeze them, when you are ready-to-eat them, take them out and let them thaw on the counter for a few hours or overnight in the fridge.
