Vegan graham cracker cake?! Yes graham crackers can be something besides crust or s’mores. Also, I lied. In Germany we don’t have graham crackers. I used “Haferkeks” (oat cookies), but the original non-vegan recipe I based this on used graham crackers so I think any cookie like graham crackers, oat cookies, Hob Nobs (which are oat cookies), Lotus Biscoff cookies, etc. would be fine for this.

I’m about to leave Germany for 4.5 months and had these cookies to use up. They were kinda boring by themselves, I originally bought them to turn into a crust for pumpkin pie, but I had extra. Since I didn’t have anything else left to use as pie I needed another option. These cookies needed to be upcycled into something more exciting!

In Germany not all the oat cookies are vegan, so check that. The ones I bought were a cheap brand from Lidl that was accidentally vegan. They had two types and one was NOT vegan.

This was kind of a mix between a cake and a brownie. Chewy but still fluffed up a bit. It reminds me of the texture of some egg-heavy cake I had growing up.

Thanks to Sweet ReciPEAS for the original inspiration. The recipe there is not-vegan and I changed a lot of ingredients because I didn’t have them, but hers is one of the only recipes that cake up for something to make out of graham crackers that isn’t crust or s’mores.

Vegan Chocolate Graham Cracker Cake

What to do with extra graham crackers or other plain cookies besides make a crust!
Prep Time 20 minutes
Cook Time 30 minutes
Course Dessert
Servings 5


  • food processor or blender
  • 13-inch pan (to be honest I used a long bread loaf pan)
  • stand mixer or whisk


  • 1/2 cup vegan butter or oil I used oil
  • 1 cup sugar I used brown sugar
  • 3 vegan eggs I used 1.5 Tbsp chia seeds powdered then mixed with 6 Tbsp water as I find chia eggs more gummy than flax eggs
  • 2 cups graham cracker crumbs I used oat cookies, i.e. Haferkeks
  • 2 tsp baking powder
  • 3 Tbsp cocoa powder
  • 1 tsp salt
  • 1 cup non-dairy milk I used water because I was out
  • 1 tsp vanilla extract


  • Preheat oven to 375F (190 C)
  • Beat vegan butter/oil in a stand miser or with a whisk and add sugar and vegan eggs, mixing until well combined.
  • Add graham cracker crumbs, baking powder, cocoa, salt, non-dairy milk, vanilla extract and mix well.
  • Pour batter into greased 13-inch pan. I used a long bread loaf pan honestly. Whatever you pour it into it should be about 1-1.5 inches high.
  • Bake 25-35 minutes until a knife doesn't come out gooey. It will still be more wet than cake, even once it cools.
  • Cool for 10-15 minutes than turn upside down and cool on a wire rack


The original recipe also includes nuts, cream and a chocolate sauce. You can do that too if you want! I think PB sauce would also be awesome. I didn’t have any of the ingredients on hand.
