FAQs
Can I use light molasses instead of dark molasses?
Yes, light molasses can be used, but it will yield a milder flavor and lighter color. Dark molasses provides a richer, more robust taste.
What can I do if I don’t have buttermilk?
You can make a simple substitute by mixing 1 tablespoon of lemon juice or white vinegar with 1 cup of milk. Let it sit for 5 minutes before using it in the recipe.

- 1/4 cup milk, or more as needed

Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan to ensure the cake doesn’t stick.
- Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, baking soda, baking powder, ground cinnamon, ground ginger, ground cloves, ground nutmeg, and salt. This blends the spices evenly throughout the cake.
- Cream Butter and Sugars: In a separate large bowl, beat the softened butter, granulated sugar, and dark brown sugar together until light and fluffy, about 3 to 5 minutes. This step is important to incorporate air for a tender texture.
- Add Eggs: Beat in the eggs one at a time, ensuring each egg is fully incorporated before adding the next for a smooth mixture.

- Pour Batter: Pour the batter into the prepared baking pan, spreading it evenly with a spatula.
- Bake: Bake in the preheated oven for 30 to 35 minutes. The cake is done when a wooden skewer inserted into the center comes out clean.

- Cream Butter for Frosting: In a large bowl, beat the softened butter until smooth and fluffy, about 2 to 3 minutes.
- Add Powdered Sugar: Gradually add powdered sugar, one cup at a time, beating well after each addition to create a smooth frosting base.

- Decorate: Decorate the frosted cake with sprinkles, candied ginger, or a light dusting of cinnamon as desired.
- Serve: Slice the cake into squares and serve. Enjoy your delicious cinnamon molasses cake!
Notes
- Ensure the cake has completely cooled before frosting to prevent melting.
- You can substitute buttermilk with regular milk plus 1 tablespoon lemon juice or vinegar if needed.
- For a deeper molasses flavor, try using blackstrap molasses instead of regular molasses.
- Store the cake covered in the refrigerator for up to 4 days.
- If you want a dairy-free frosting option, substitute butter with a vegan butter alternative and use plant-based milk instead.
