Step 1

Preheat oven to 350 degrees. Spray a 9×13 baking dish with nonstick spray. In a small bowl, combine 1/3 cup brown sugar and 1/4 teaspoon cinnamon. In another small bowl, combine flours, baking powder, salt, nutmeg and cinnamon, then whisk to combine.

Step 2

In a large bowl, add butter and sugars and whisk until smooth. Whisk in eggs one a time, mixing until completely combined, then stir in vanilla extract. Stir in dry ingredients, mixing until a batter forms, then whisk in eggnog until smooth. Pour half of the batter in the baking dish, then sprinkle the brown sugar/cinnamon mixture over top. Cover with remaining batter, gently using a spatula to spread over sugar if needed. Don’t worry if some of the sugar peeks through. Top with the crumble.

Step 3

To make the crumble: Combine all ingredients in a bowl and mix until crumbly. Sprinkle evenly over cake, then bake for 30-35 minutes, or until cake is set in the middle. While cake is baking, make glaze below. After removing cake from oven, immediately poke holes all throughout the cake with a toothpick, then drizzle glaze over top.

Step 4

To make glaze: Whisk all ingredients together in a small saucepan over medium heat, and allow to come to a boil. Reduce to a simmer and cook for 1-2 minutes, then remove from heat and let sit until cake is finished.

Step 5

Note: You can use dairy or non-dairy eggnog. In the last month I’ve made this with cow’s milk eggnog and coconut milk eggnog – great result each time!
