Cinnamon does the heaviest structural and aromatic lifting in this bake, infusing both the dense crumb layer and the buttery topping with distinct warmth. To ensure the spices distribute evenly without clumping, whisk them thoroughly into the dry ingredients before introducing any fats. When preparing the six-inch round pan, grease it thoroughly and dust it with flour, tapping out any excess to prevent the delicate batter from sticking during baking.
Mix the crumb topping using melted butter rather than cold cubes, stirring until no dry pockets of flour remain to guarantee uniform pebble-sized clusters. For the cake batter itself, add the wet ingredients to the dry bowl and stir with a fork only until combined. Overworking this mixture develops gluten strands that result in a tough, rubbery texture instead of a tender crumb.
Evaluate the doneness of the cake by inserting a metal skewer into the center rather than relying on guesswork. A finished cake should yield a skewer that emerges completely clean, free of wet batter, after approximately thirty-five minutes in an oven preheated to 375 degrees Fahrenheit. Let the baked cake rest on a wire rack for at least thirty minutes before slicing to allow the interior structure to set properly.
Store leftovers in an airtight container at room temperature for up to three days, or freeze tightly wrapped individual slices for longer storage. Reheat frozen portions briefly in a warm oven to restore the crisp texture of the cinnamon crumb topping before serving with an optional dusting of confectioners' sugar.
