How to Make Buttermilk Sheet Cake with Chocolate Fudge Frosting
Creating this Buttermilk Sheet Cake is a straightforward process. You begin by prepping your baking pan and mixing the wet ingredients until creamy. Then, you’ll whisk together your dry ingredients and alternate adding them to your mixture with the buttermilk. The result is a smooth batter that you pour into your prepared pan. After baking until golden and set, let it cool completely before you move on to the rich chocolate fudge frosting.
Once the cake has cooled, whip up the frosting using butter, cocoa powder, powdered sugar, and milk for that thick, creamy texture. Spread the frosting generously over the top of the cake, and you’re ready to cut slices!
Ingredients
To whip up this delightful cake and frosting, gather these items:
3/4 cup butter (room temperature)
1 1/2 cups sugar
4 large eggs
3 cups cake flour
1 teaspoon baking powder
1 teaspoon salt
1 cup buttermilk
2 teaspoon vanilla extract
3/4 cup butter (room temperature, for frosting)
2 1/2 cups powdered sugar
1/2 cup unsweetened cocoa powder
5 Tablespoons buttermilk (for frosting)
1 teaspoon vanilla extract (for frosting)
1/4 teaspoon almond extract
Make sure your butter is at room temperature for the best incorporation into the batter. If you’re looking to switch things up, you can use whole milk or yogurt in place of buttermilk.
Directions
Preheat oven to 350 degrees. Spray a 9×13″ baking pan with non-stick baking spray. Set prepared pan aside. In a mixing bowl and a stand or hand mixer, beat butter and sugar on low until creamy. Stopping to scrape down the sides, add eggs one at a time. Continue to beat on low until all eggs are incorporated and batter is creamy.
In a separate bowl, whisk together the flour, baking powder, and salt. In a liquid measuring cup, measure out buttermilk. With the mixer on low, begin adding the dry ingredients to the batter, and alternate pouring in the buttermilk in gradual increments. When all ingredients have been mixed, add the vanilla and mix until completely incorporated. Pour batter into the prepared pan and evenly smooth with a spatula. Bake at 350 for 26-28 minutes or until a toothpick inserted into the cake comes out clean with no crumbs. Let cake cool after baking.
To prepare the chocolate frosting, beat the room temperature butter, powdered sugar, cocoa powder, buttermilk, vanilla extract, and almond extract together until smooth and fluffy.
Spread the frosting over the cooled cake before serving, and enjoy!

How to Serve Buttermilk Sheet Cake with Chocolate Fudge Frosting
This cake is best served at room temperature and makes an excellent treat alongside a hot cup of coffee or tea. For a fun twist, you can slice it into squares and serve with a scoop of vanilla ice cream on the side. If you have fresh fruits on hand, consider adding strawberries or raspberries for a refreshing contrast to the rich chocolate flavor. Enjoying it on a special plate can make even simple moments feel festive.
How to Store
To keep your buttermilk sheet cake fresh, store any leftovers in an airtight container at room temperature for up to three days. If you want to extend its shelf life, consider refrigerating it, where it will last for about a week. This cake freezes well too! Wrap it tightly in plastic wrap and aluminum foil, and it can stay in the freezer for up to three months. Just allow it to thaw in the fridge overnight before serving.
Tips to Make
For extra moistness, make sure to use fresh buttermilk. If you cannot find buttermilk, you can make a quick substitute by mixing milk and vinegar or lemon juice. When baking, keep an eye on your cake in the last few minutes of baking—ovens can vary, and you want to avoid overbaking. Finally, let the cake cool completely before frosting to prevent the frosting from melting.
Variations
Feel free to get creative with this recipe! You can add spices like cinnamon or nutmeg for a warm, cozy flavor complex. For a fun twist, consider adding chopped nuts or mini chocolate chips to the batter before baking. If you want to lighten the recipe, you could use a lighter whipped topping instead of frosting for a lower-calorie option—but who can resist the chocolate fudge?
