Acorn flour has a delicious roasted nutty flavor, plus it's edible and nutritious. Making acorn cookies is a great way to use foraged acorns! This recipe makes 36 cookies.
Combine the flour, acorn flour, baking powder, and salt in a medium bowl.
In a large bowl combine the butter and brown sugar until it is creamy. Stir in the egg and vanilla.
Add the dry ingredients to the wet ingredients and stir until it comes together into a dough. If the dough is sticky you can add a little more flour as needed.
Divide the dough into two halves and roll each one out onto a lightly floured piece of parchment paper until it’s about 1/4 inch thick.
Place one rolled-out dough on parchment on a sheet pan, then put the second rolled-out dough on parchment on top of the first. Then cover the top dough with plastic wrap or beeswax wrap.
Refrigerate the rolled-out doughs for at least 1-2 hours or overnight.
Once the dough has been chilled, preheat the oven to 350°F (175°C). Line a sheet pan with parchment paper or a silicone baking mat. Pull one rolled-out dough out of the refrigerator.
Use acorn shaped cookie cutters to cut the dough into acorn shapes (or whatever shapes you like). When you’ve used all the dough you can re-roll the scraps to cut more shapes.
Put the cut out acorns onto the baking sheet with an inch or so in between them. Bake for 11-12 minutes or until the edges are just starting to turn brown.
Let the cookies cool on the sheet pan for several minutes before moving them to a cooling rack.
Repeat with the remaining dough until all the cookies are baked.
Notes
Acorn flour can be made from foraged acorns, but it is a bit of a process. If you prefer, purchase acorn flour online.Since acorn flour is starchy, it works best to mix it with regular flour for baking. If you want more acorn flour in the mix, feel free to experiment with using a higher ratio of acorn flour to wheat flour. I haven’t tried this so I can’t guarantee the results.These cookies are delicious without any icing. To ice them, I recommend the maple icing from my maple cookies. Let the cookies cool completely before icing.Store acorn flour cookies in an airtight container at room temperature on the countertop.
