Preparation

• Preheat the oven to 350°F (177°C). Grease a 9-inch square or springform baking pan with nonstick spray. Set aside.
• Make the crumb topping first: In a medium bowl, whisk the flour, brown sugar, and cinnamon together. Cut in the cold butter using a pastry blender or a fork. Mix to create clumps and crumbs. Set aside.
• Make the cake: Whisk the flour, baking soda, baking powder, salt, cinnamon, nutmeg, cloves, and ginger together in a large bowl until combined. In a medium bowl, whisk the pumpkin, brown sugar, oil, maple syrup, and milk together until combined. Pour the wet ingredients into the dry ingredients and stir until just combined. Spoon/pour the batter into the prepared baking pan and spread to make an even surface. Pour the crumb topping evenly on top and gently press them down into the batter.
• Bake the cake for 30-35 minutes. Check the cake’s doneness at the 30 minute mark by inserting a toothpick into the center. If the toothpick comes out clean or with a couple moist crumbs, the cake is done. If the toothpick has wet batter on it, bake for 5 more minutes or until the toothpick comes out clean.
• Make the icing: Whisk the icing ingredients together. Add an extra splash of creamer/milk to thin out if desired. Drizzle over warm or cooled cake.
• Cover leftover cake tightly and store at room temperature or in the refrigerator for up to 3 days.
