Maple walnut cookies! Invite fall season with this intense cookie to your home. If you love maple and walnuts, this cookie is for you. Unfortunately, it is not that common in Germany to eat cookies all year round, but now with temperature dropping and days getting shorter, even here in Germany cookies are being baked more often and the oven turned on. So even in Europe we finally have no excuse, turn on your oven and make these maple walnut cookies!
