Instructions
Preheat the Oven: Set your oven temperature to 350°F (175°C). Prepare a 9x13-inch baking pan by greasing it with butter or cooking spray, then lightly flour it to prevent sticking.
Make the Cake Batter: In a large mixing bowl, beat the softened butter and granulated sugar together using an electric mixer on medium speed until the mixture becomes light and fluffy, about 3-4 minutes.
Add Eggs and Eggnog: Add the eggs one at a time, mixing well after each addition. Pour in the eggnog and vanilla extract, stirring until the mixture is fully combined and smooth.
Incorporate the Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, ground nutmeg, ground cinnamon, and salt. Slowly add this dry mixture to the wet ingredients, folding gently until just combined. Be careful not to overmix.
Prepare the Crumb Topping: In another bowl, combine the brown sugar, chopped pecans (if using), additional flour, and ground cinnamon. Pour in the melted butter and use a fork or your fingers to mix everything until crumbly, creating pea-sized clumps.
Combine and Layer: Pour half of the cake batter into the prepared baking pan, spreading it evenly with a spatula. Sprinkle half of the crumb topping evenly over the batter. Carefully pour the remaining batter over the crumb layer, smoothing it out again before topping it with the rest of the crumb mixture.
Bake the Cake: Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on it towards the end of baking to ensure it does not overbake.
Cool and Serve: After baking, let the cake cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely.
Notes
Cut the cake into neat squares and serve it warm or at room temperature. For a festive touch, dust the top with powdered sugar and add whipped cream on the side.
