Cassava Flour Peanut Butter Swirl Brownies

I don’t make a lot of peanut buttery stuff any more, seeing how hard legumes are on the tummy, but every now and again I get a craving for a Reese’s-ish type dessert. These definitely hit the spot! They are a knock-off of my original buckwheat peanut butter swirl brownies (which are still totally yum). With my diet the way it is currently, I just needed a buckwheat-free version, so I modified that recipe to fit my needs. 🙂

Cassava flour.

In case you were wondering, these cassava flour brownies are made with cassava flour. Beside being my current favorite grain-free flour, cassava flour is full of nutritional value: it’s high in vitamin C, potassium, folate, magnesium, and phosphorus. I get my organic cassava flour from Azure Standard – it’s usually cheaper than anywhere else, and it’s great quality!

I have not tried these brownies with almond flour, or any other grain-free flour. I do have a similar recipe made from buckwheat flour though, if you would like to try those instead.

Coconut sugar.

I use both honey and coconut sugar for these peanut butter swirl brownies. Coconut sugar is a natural sugar, and my body seems to handle it well. Plus, I love the texture it gives my desserts! I get my  organic coconut sugar from Azure Standard. If you want, you could try just using 1/2 cup of one or the other, instead of 1/4 cup of each. I haven’t tried this, but I don’t see why it wouldn’t work.

Cocoa powder.

The fair-trade, organic cocoa powder from Azure Standard is absolutely the best. It’s deep and delicious, and the cheapest cocoa I can find! Of course, you can always use whatever cocoa powder you have on hand.

Peanut butter.

I usually get my organic peanut butter from Aldi, but you can definitely use whatever brand you can find. Organic peanut butter tends to be runnier than “normal” peanut butter, but that’s ok for this receip. Just make sure it’s stirred together and not separated.

Sour cream.

I know, this is a strange ingredient for brownies! But trust me – it works! As my husband says, “You can’t even taste it.” If you can’t do dairy, you could use a dairy-free sour cream sub, or try dairy-free yogurt. Yogurt does tend to be runnier than sour cream, though, so using yogurt might mess with the consistency of the recipe.

Grain-free brownies.

If you’re in the mood for brownies, but these are hitting the spot, here are a few more of my favorites to check out!
