Step By Step Instructions – Graham Cracker Cake

Here is how to make and bake the graham cracker cake. This cake recipe requires an electric mixer. A stand mixer with paddle attachment or a hand mixer will work.

STEP 1: Prep. Preheat the oven to 350°F. Then, spray two 8 inch cake pans with baking spray. Line the bottoms with parchment paper circles and spray them again.

STEP 2: Dry ingredients. Sift together the all purpose flour, baking powder, baking soda, and salt in a medium bowl. Add the graham cracker crumbs in and set it aside.

STEP 3: Beat butter, oil, and sugar. Use a mixer to beat the butter, oil, and sugar for 2 minutes on high speed.

STEP 4: Wet ingredients. Add the sour cream, vanilla extract, and eggs to the butter mixture. Mix them in on medium speed until just combined.

STEP 5: Combine. Add 1/3rd of the dry ingredients and half of the buttermilk and mix them in on low speed. Then, add another 1/3 of the dry ingredients and the other half of the buttermilk. Mix them in on low speed. Finish with the remaining dry ingredients.

STEP 6: Pour batter. Divide the batter into the prepared cake pans in an equal and even layer.

STEP 8: Cool. Let the cakes cool in the hot pans for 10 minutes before transferring them to a cooling rack to cool completely.

Step By Step Instructions – Frosting and Filling.

Here is how to make the chocolate cream cheese frosting and prepare the marshmallow filling. See my chocolate cream cheese frosting post for more tips.

STEP 3: Combine. Add in half of the cocoa powdered sugar and mix it on low speed until just combined. Add the remaining cocoa powdered sugar and mix it on low.

Assembling the Cake

Here is how to assemble the s’mores cake.

STEP 1: Even out layers. Use a serrated knife to cut the domes off the top of the cake layers to make them even.

STEP 2: First layer. Place the first cake layer down and spread 1/2 cup of chocolate frosting over it with an offset spatula. Pipe a border of frosting around the edge to hold in the marshmallow. Then, spread 1/2 cup of the marshmallow filling over the center.

STEP 3: Second layer. Place the second layer of cake on top.

STEP 4:Crumb coat. Frost the cake in a light layer of frosting (called a crumb coat). Freeze the cake for 15 minutes to solidify this layer and lock in any crumbs.

STEP 4: Frost cake. Frost the rest of the outside of the cake. Then, place the entire cake in the freezer for 10 minutes to prepare for decorating.

STEP 5: Prep marshmallow. Mix 1 TBSP of water into the marshmallow filling. You may need to heat it in the microwave.

STEP 6: Marshmallow drip. Place the remaining half of the filling into a piping bag. Make the marshmallow drip over the sides of the cake.

Expert Baking Tips

  • Properly measure the flour- Make sure the flour is spooned and leveled. If you stick the measuring cup directly into the flour, it will compact the flour. Compacted flour can cause the cake to be dry.
  • To easily remove the cake from the pan, make sure to first spray the pan with baking nonstick spray. Then, line bottom with parchment paper and spray it again to make sure that the paper does not stick to the bottom of the cake too much. If you miss any spots with the spray they can stick and tear the cake so be thorough.
  • For high altitude baking add 2 Tbsp of flour to the cake batter.
