In a medium bowl, whisk together almond flour, coconut flour, baking soda and salt; set aside.: The moment you combine the dry ingredients you will notice the nutty scent of almond flour and the drier, slightly coconut aroma from coconut flour . Whisking distributes the baking soda and salt evenly so every bite has balanced lift and seasoning. If you skip this step, you risk uneven pockets of leavener or salt which can cause metallic or overly salty notes in some cookies. Watch for a uniform pale mixture with no streaks, and avoid overwhisking which can aerate coconut flour excessively.
In the bowl of your stand mixer (or you could use a hand mixer), cream together butter, coconut oil, sugar and Stevia. Then add the egg and vanilla, mixing until combined.: As you cream the softened butter with the sugars, listen for the change in sound as the mixture becomes lighter and smoother, and smell the rich, buttery scent lift. This creaming traps tiny air pockets that contribute to a tender crumb and gentle rise. A common mistake is using butter that is too warm, which yields greasy, flat dough. Aim for a pale, fluffy mixture before proceeding to the egg stage, scraping the bowl so nothing clings to the sides.
While the mixer is still running, slowly add the flour mixture to the creamed ingredients cupfuls at a time until all combined.: After adding the egg and vanilla , the batter will look glossy and cohesive. The egg adds structure and moisture, while the vanilla brings warmth to the aroma. If you under-mix, you may see streaks of egg white or uneven texture; if you overmix, the batter could tighten and lose tenderness. Mix just until homogeneous, and pause to scrape the bowl so all ingredients are evenly integrated.
Form the dough into a ball and wrap with plastic wrap. Chill the dough in the fridge for at least one hour, but best overnight.: Adding the dry mixture gradually prevents clumps and ensures an even hydration of the flours. You will notice the dough thicken and take on a pliable, slightly tacky feel. If you dump all the flour in at once, you risk a lumpy dough or overworking the mixer, which can make the texture gummy. Stop when the flour is fully incorporated and the dough pulls away from the bowl slightly.
Preheat oven to 350 degrees F and line two baking sheets with parchment paper or silpat baking mats.: Chilling firms the fats so the dough is easy to roll and the flavors meld into a smoother profile. The scent will deepen slightly as the ingredients relax. Rushing this step often leads to excessively sticky dough that tears while rolling; if that happens, return it to the fridge in 15 to 20 minute intervals until manageable. When ready, the chilled dough will be cool and firm yet pliable.
Roll out the dough between two pieces of parchment paper to about 1/4" thickness and cut into shapes. You will need to continually roll out the dough so if it gets too sticky you can place the dough back in the fridge (or freezer) to chill again so that it's easier to roll out.: As the oven warms to 350 degrees F you may notice a faint nutty aroma from the slightly warmed air, and preheating ensures even baking from the moment cookies go in. Lining sheets prevents sticking and facilitates easy removal. Baking on a cold sheet or without proper lining can cause uneven bottoms or sticking, so prepare your pans in advance and let the oven fully reach temperature before baking.
Transfer cookies to baking sheets and bake in the oven for 10 to 13 minutes, until slightly golden. Allow cookies to cool completely on a wire rack before decorating.: Rolling between parchment keeps the surface clean and prevents extra flour from drying the dough. Look for a smooth surface without cracks and an even thickness of about 1/4 inch which yields a tender cookie that holds detail. If the dough softens while you work, it will stick and tear which leads to misshapen cookies, so chill briefly as needed. Keep your cutters sharp and press straight down to maintain clean edges.
While the cookies are cooling, add the chocolate and coconut oil to a small microwavable-safe bowl and melt in the microwave in 15 to 30 second intervals (mixing each time) until you reach the desired consistency. Dip the tops of the cookies into the melted chocolate and immediately top with sprinkles. Enjoy!: In the oven you will hear a quiet hush and begin to see the edges acquire a pale golden tint, the cue that they are ready. Baking 10 to 13 minutes yields cookies that are set but still tender in the middle; overbaking will make them dry and brittle. A common trap is opening the oven too often which lowers the temperature and can alter baking time, so check through the oven window when possible. Once out, let them rest on a wire rack so steam escapes and surfaces dry fully before adding any coating.
While the cookies are cooling add the chocolate and coconut oil to a small microwavable safe bowl and melt in the microwave in 15 to 30 second intervals mixing each time until you reach the desired consistency Dip the tops of the cookies into the melted chocolate and immediately top with sprinkles Enjoy: Melting the white chocolate chips with a tablespoon of coconut oil gives a glossy, smooth coating perfect for dipping. Heat in short bursts and stir between intervals, feeling the warmth and watching for a silky sheen that indicates readiness. Overheating will cause the chocolate to seize and become grainy, so stop heating as soon as it becomes mostly melted and finish stirring off heat. Dip and add sprinkles immediately so they adhere before the coating sets. Serve once the coating is fully dry for the best texture and presentation.
