The walnuts and apple pair well with rhubarb in this coffee cake recipe from The Pocket Rhubarb Cookbook by Nina Mukerjee Furstenau. Sprinkle a generous amount of turbinado or other raw sugar on top for a little extra pizzaz. Not to mention, in a surprising twist for most baked goods, this recipe gets better the next day. If using frozen rhubarb for this recipe, be sure to measure it out while still frozen, then completely thaw in a colander. Just be sure not to press the liquid out of the rhubarb before making this coffee cake.
Why Does Coffee Cake Not Use Coffee?
The curious case of coffee cake and its lack of coffee lies in its historical purpose rather than its ingredients. Originating in Europe, likely Germany, in the 17th century, coffee cake did not intend to contain coffee, but rather to be the perfect accompaniment to a cup of coffee. As coffee houses became popular, these sweet and spice-full cakes and breads were served alongside the bitter beverage to create a balanced experience. This tradition of pairing a sweet treat with coffee takes coffee cakes to America, where they often feature a crumbly streusel topping and then sometimes a swirl of cinnamon, maintaining its identity as the ideal partner for your morning or afternoon coffee break.
