These may very well be my favourite cookie (though with choices like Oat Flour Peanut Butter Cookies and Oatmeal Cookies it can be hard to choose!).

But if I really really had to... It would probably be these snickerdoodles! Made entirely in ONE BOWL, they are ready in mere minutes (which is almost dangerous), are so so soft and taste incredible.

And as a bonus, they freeze really well. So if you can't be trusted to have 30 cinnamon-spiced cookies staring at you from the counter, fear not. Just pop them in the freezer- out of sight, out of mind (maybe..).

The Ingredients

• Oat Flour- I tested this recipe with both boughten and homemade oat flour and highly recommend using boughten. When making oat flour homemade, the results can be inconsistent depending on how fine you are able to grind it. If you need this recipe to be gluten free, ensure that you are using certified gluten free oat flour.
• Butter- You can use either salted or unsalted butter. If using salted butter, omit the added salt in the recipe.
• Granulated Sugar- I tested this recipe with coconut sugar as well but found the results to be less soft and thick as well as a darker cookie.
• Egg
• Egg Yolk- An extra egg yolk in addition to the egg helps to create the chewy texture of these cookies. Try using the extra egg white to make some Chunky Chocolate Granola!
• Vanilla
• Cinnamon
• Cream of Tartar- Acts as a leavener and gives snickerdoodles their signature "tang".
• Sea Salt- Omit if using salted butter.

The Method

1. Mix dough. Using a stand mixer, hand mixer or by hand with a fork, cream together butter and sugar until fluffy. Add the egg, egg yolk and vanilla and combine. Mix in the cinnamon, cream of tartar and salt. Finally, add the flour and mix until well combined. *See below for how to measure oat flour for this recipe and be sure to check out this post about baking cookies with oat flour for more tips.

2. Prepare Cinnamon Sugar. In a small, shallow bowl, add the second amount of sugar and cinnamon and stir to combine.

3. Shape. Scoop 1.5-2 tablespoon of dough per cookie and roll into balls.

4. Roll in Sugar. Roll each ball in the prepared cinnamon sugar until coated and place on a prepared baking sheet. Place cookies at least 2 inches (5 cm) apart.

5. Flatten. Using your hand or the back of a spoon, flatten each of the cookies slightly so that they are a bit wider than tall (a little over ½ inch / 1 cm tall).

6. Bake. Bake at 350 F for 8-11 minutes until the edges are set and very lightly browned. The centre will still be fairly soft.

7. Flatten and top. Remove the cookies from the oven and use the back of a spoon to flatten the tops a bit more and top with additional cinnamon sugar if desired.

8. Cool. Let the cookies cool on the baking sheet for 5 minutes then use a spatula to move to a wire rack to cool completely.

How to Measure Oat Flour

Oat flour is less dense than wheat flour. All purpose flour weighs 120 g per cup when spooned and levelled into a measuring cup while using the same method for oat flour will yield 80-90 g per cup.

After several trials, I have found that I can consistently achieve 120 g per cup of oat flour (therefore comparable to AP flour and helpful when trying to substitute oat flour for part or all of AP flour in a recipe), if I scoop the oat flour into a measuring cup, lightly pack it down and then level off the top (see the image below).

So if you are not weighing your ingredients for this recipe, it is important that if you are that you measure the oat flour in this way. Scoop, lightly pack and then level off.

Leftovers

Make Ahead: Cookie dough can be made up to 3 days ahead, covered and kept in the refrigerator. You can shape the dough into balls and roll it in cinnamon sugar before refrigerating or do that when you are ready to bake. When you want to bake them, remove the dough from the fridge 30 minutes prior to allow it to come to room temperature. Resume with the recipe where you left off.

To Freeze Cookie Dough: Shape into balls, roll in sugar and place in a single layer on a large plate or cookie sheet. Freeze until solid and then package into an airtight container or zip top bag. When ready to bake, remove desired amount of cookie balls from freezer and place on a prepared cookie sheet. Allow to thaw and come to room temperature- about 30-45 minutes, squish down slightly and bake as directed.

To Store: Cool oat flour snickerdoodles completely and store leftovers in an airtight container at room temperature for up to 4 days or freeze for up to 3 months.

Make it Your Own

Want to change it up? Try one of these variations or a combination of them!

• Chai Spice Oat Snickerdoodles- Combine 1 and ½ teaspoon cinnamon with 1 teaspoon cardamom and 1 teaspoon ginger. Use 3 teaspoon (1 tbsp) in cookie dough in place of the cinnamon in the dough and use the remaining spice mixture mixed with sugar in place of cinnamon for rolling.
• White Chocolate Oat Flour Snickerdoodles - Mix in up to 1 and ½ cups of white chocolate chips.
• Oat and Nut Snickerdoodles - Add up to 1 and ½ cups of raw, chopped nuts such as pecans or almonds.

Serving Ideas

Oat Flour Snickerdoodles are great for sharing at picnics, potlucks and more- especially if you need a gluten free cookie (make sure you use certified GF oat flour if needed!).

You could also enjoy them served warm with vanilla ice cream...

Or use them to make snickerdoodle ice cream sandwiches!
