Making your own almond flour or oat flour is not only easy, it’s practical. Both of these flours are higher in fat and protein than starches or even my all purpose flour blend, hence, they become rancid more quickly and should be refrigerated. Making fresh flour for your recipes will ensure that your don’t waste flour that you cannot use quickly enough. These flours also tend to be pretty pricey, so I highly recommend making your own for that reason as well!
Almond flour or meal can be ground to different consistencies: flour is the finer ground version of almond meal. I prefer not to use blanched almonds for grinding (blanched almonds have the brown skins removed), since the skins contain a lot of nutrients and their added texture doesn’t bother me. If you want the finest flour you can get though, use blanched almonds as your base.
For oat flour, just be sure to select certified gluten-free rolled oats, like my Jules Gluten Free Quick Oats. Steel cut oats also don’t tend to grind into flour well, but if it’s all you have on hand, you can grind it to a coarse flour that will work in some recipes.
Both almond flour/meal and oat flour can be used to increase the nutritional value of gluten-free baked goods (see my Pineapple Upside-Down Cake recipe!), and they can even be used with some success as a replacement for milk powder in many recipes. They add weight to recipes though, so they are not well-suited for delicate baking.
To make 1 Cup Almond Flour/Meal:
Measure out 1 cup of whole, unblanched almonds (may use blanched almonds, but since their skins are removed, they are less nutrient-dense). Place them into a clean coffee grinder, blender or food processor – depending on the size of your machine’s bowl, you may need to divide the almonds into two portions and process separately.
Cover with the lid and pulse, grinding the almonds into meal. (This recipe will work with a fine almond flour or a coarse almond meal). Be careful when grinding almonds or other nuts, as over-processing will quickly take flour/meal to nut butter!
Sift the meal to remove larger pieces, allowing the fine particles to settle into a separate bowl. Repeat until all the medium-large pieces are separated and processed until fine.
Measure out 1 cup of almond flour/meal and reserve any extra by placing in a zip-top bag and refrigerating for up to one month for use in another recipe.
To Make 1 Cup Oat Flour:
Measure out 1 cup of certified gluten-free rolled oats (quick oats work best). Place them in a clean coffee grinder, blender or food processor – depending on the size of your machine’s bowl, you may need to divide the oats into two portions and process separately.
Cover with the lid and pulse, grinding into a fine flour. Measure out 1 cup of oat flour and reserve the remaining in a small zip-top bag and refrigerating for up to one month for use in another recipe
