Instructions

Prepare the Crumb Topping

Prepare the Gingerbread Cake

  • Preheat the oven to 350°F.
  • Spray a 9x13-inch baking pan with baking spray.
  • In the bowl of a stand mixer, add the softened butter and dark brown sugar.
  • Cream the butter and sugar together until light and fluffy.
  • Add the molasses and mix until combined.
  • Add the eggs and vanilla extract.
  • Mix until the wet ingredients are fully incorporated.
  • In a separate mixing bowl, sift together the all-purpose flour, whole wheat flour, baking soda, ground cinnamon, ground ginger, ground cloves, and salt.
  • With the mixer on the lowest speed, add half of the dry ingredients to the butter mixture.
  • Add half of the buttermilk and mix until just combined.
  • Add the remaining dry ingredients, followed by the remaining buttermilk.
  • Mix only until the batter is combined. Do not overmix.
  • Pour the batter into the prepared baking pan.
  • Spread the batter evenly into the pan with a spatula.
  • Break the prepared crumb topping into chunks about the size of marbles.
  • Scatter the crumb topping evenly over the cake batter.
  • Bake for 35 to 40 minutes, or until a knife inserted into the center of the cake comes out clean.
  • Remove the cake from the oven.
  • Allow the cake to cool before slicing and serving.

Notes

To make this Gingerbread Crumb Cake gluten free, replace the all-purpose flour and whole wheat flour with a high-quality 1:1 gluten-free all-purpose baking flour blend.
Replace the cake flour in the crumb topping with a gluten-free cake flour blend or a gluten-free 1:1 baking flour blend suitable for tender baked goods.
Confirm that the molasses, baking soda, spices, vanilla extract, brown sugar, butter, and buttermilk are labeled gluten free.
If using a gluten-free flour blend without xanthan gum, add xanthan gum according to the flour brand’s instructions.
Mix the batter only until combined, as gluten-free cakes can become dense if overmixed.
Use clean bowls, utensils, measuring tools, and baking pans to prevent cross-contamination.
