Start preheating the oven to 350F/175C. Soak the raisins in boiling hot water and set them aside.Then, cube the butter and add it to a small saucepan. Use a light-colored saucepan to monitor the butter's color change.
113 grams butter,, 150 grams sultana raisins
Heat the butter over low-medium heat until it melts and starts bubbling. From that point on whisk the butter occasionally to prevent burning. Don't walk away from the stove! The butter can go from light brown to dark brown to burnt in 1 minute. Once you see an amber color and smell the nutty fragrance, turn off the heat and immediately pour the butter into a mixing bowl. The residual heat of the pot can burn the butter even if it is already off the fire!
Break up the lumps in brown sugar, then add both sugars to the melted butter, and whisk to incorporate.
100 grams granulated or caster sugar,, 50 grams brown sugar,
Let the mixture cool before adding the egg (5-10 min). If you add the egg to the hot butter, the egg will cook and ruin the dough. Once the butter mixture has cooled, add the egg and vanilla and whisk to incorporate.
1 medium-large egg, 1 teaspoon vanilla extract
Now, add buckwheat flour, baking soda, baking powder, salt, and cinnamon to the bowl with the wet ingredients and mix to combine.
120 grams light buckwheat flour,, ½ teaspoon baking powder,, ½ teaspoon baking soda,, ½ teaspoon salt, 1 teaspoon ground cinnamon
You can use a whisk, a spatula, a wooden spoon, or an electric mixer for this step. Make sure your baking powder is gluten-free and baking soda is active.
Add quick oats and mix them into the cookie dough with a spatula, wooden spoon, or an electric mixer.
120 grams gluten-free quick oats
Finally, drain the raisins and add them to the mixing bowl. Fold the raisins in until the dough comes together and looks consistent all throughout.

The dough will be thick and somewhat sticky. You can bake the cookies right away or refrigerate the dough for up to 3 days. You don't need to chill the dough before baking.
Rinse your hands in water to prevent sticking and shape the dough into medium-sized balls, about 1.5 tablespoon in volume.The recipe makes 21 cookies, so you will need 2 baking sheets lined with parchment paper or greased with non-stick spray or oil. My baking sheets normally fit 9 balls per tray, so it takes 3 rounds of baking to make this recipe. You can bake two trays at once, but keep in mind that the bottom sheet will have crispier cookies. Bake the cookies for 10-12 minutes at 350F/175C, take them out, and let them sit on the baking sheet for 3-5 minutes before transferring them to a cooling rack. Enjoy!Cookies baked for 10 minutes will be softer, while the ones baked for 12 minutes will be crispier on the outside with a softer interior.

To defrost, simply warm up a cookie or two in the microwave for 1-2 minutes or in the oven at 300F/150C for 5-10 minutes.
