Making the Ultimate Chocolate Fudge Cake Step by Step
Please see the recipe card below for measurements!
STEP ONE: In a medium bowl, whisk flour, cocoa powder, baking powder, baking soda and salt together. Then set aside the dry ingredients.
STEP TWO: In a large mixing bowl, cream together the butter and granulated sugar with an electric hand mixer on high speed until fluffy, about 3-4 minutes. (If using the bowl of an electric mixer, use the paddle attachment.)
STEP THREE: Then add in the eggs and vanilla and mix on medium then medium-high speed until smooth, pale in color and slightly fluffy, about 2-3 minutes. Scrape the sides of the bowl with a rubber spatula as needed.


STEP FOUR: Add the dry ingredients and the buttermilk to the butter mixture a little at a time, until all has been added, mixing on low then medium speed for each addition. Mix just until the batter is combined and smooth, scraping the sides of the bowl as necessary
STEP FIVE: Add in the hot coffee and mix on low speed just until dispersed through the batter.


STEP SIX: Pour the cake batter into a 9x9 pan lined with parchment paper. Bake the cake for 48-52 minutes, or until a toothpick comes out clean from the center of the cake. Let the cake cool in the pan on a wire rack to until completely cool.


STEP SEVEN: To make the chocolate fudge frosting, melt the butter in a small saucepan over medium heat. Add the melted butter, salt and cocoa powder to a large bowl. Combine together with an electric mixer on medium-low speed. (If using a stand mixer, use the whisk attachment.)
STEP EIGHT: Sift in the powdered sugar and add in the heavy cream a little at a time, mixing on low speed for each addition. When all has been added, mix on high speed until silky smooth, about 2 minutes. If the frosting isn't the right spreadable consistency, add more cream a tablespoon at a time until it's silky smooth.


STEP NINE: When the cake is completely cooled, remove it from the pan and transfer it to a serving plate. Spread the fudge frosting on top of the cake with an offset spatula. I like to add little swirls to make it look more interesting. Sprinkle chocolate shavings or mini chocolate chips over top and serve!


FAQs
Do I have to use coffee in the cake batter? If you don't want to use coffee, you can use hot water instead.
How do I store this cake? Store leftovers in an airtight container in the fridge for up to three days. The cake is best enjoyed at room temperature, so for the best taste, let it sit at room temperature for 30 minutes before enjoying. You can also freeze individual pieces by wrapping each in plastic wrap, and then putting them in an airtight container. Freeze for up to 2 weeks.

PRO TIPS
Measure your flour properly. This is always my #1 baking tip. Do not ever scoop a measuring cup into your flour. This will always lead to using too much flour. Instead sprinkle spoonfuls of flour into your measuring cup and swipe excess flour off with the back of a knife. Or better yet, weigh your flour. 1 cup of flour equals 125 grams.
For best results, use room temperature ingredients. You'll have the best textured cake when the ingredients are room temperature instead of cold. Cold wet ingredients can lead to a "gummy" cake.

Great that you have posted ingredient quantity along with each step. 🙂
I loveeee your recipes and wanted to make this for Easter lunch. I only have an 8x8 square and a 9in round. Would I be able to use one of these?
Thank you!
I made this today. It has a huge amount of sugar but I went with it thinking that must be for the unique texture the cake is meant to have. The cake came out well but it is extremely sweet. All I taste is sugar. I was looking for a deep chocolate flavour. This did not work for me.
