Soo I had a request for an Oreo Confetti Cake not too long ago – with one catch; the cake needed to be vegan. ::insert gulp::

I’m soo very definitely NOT an expert vegan baker, soo I quickly consulted ‘ItDoesntTasteLikeChicken’s site to get an idea of how to substitute out the butter, eggs, and buttermilk that I usually use!

Be warned; follow the directions carefully on this one! I tried to use a bit more oil and less almond milk (because I was running out), and it completely messed up the cake texture and I had to start over. I definitely recommend just saving yourself the guesswork and the headache - and just follow the recipe!

  • 3 ¾ cup all-purpose flour
  • 2 ¼ cup  granulated sugar
  • 3 teaspoons baking powder
  • 1 teaspoon  salt
  • 2 cups non-dairy milk (I used almond milk)
  • 1 cup light oil (I used vegetable oil; canola oil is another option)
  • 2 teaspoons clear vanilla extract
  • 3/8 cup lemon juice or apple cider vinegar (I used lemon juice)
  • Stir in at the end – 12 crushed Oreos & about ½ cup of rainbow jimmies (NOT nonpareils; the color will dissolve and turn the cake brown!)
Vegan Oreo Confetti Frosting
  • ¾ cup Vegan butter (I found this at my local grocery store)
  • ¾ cup vegetable shortening
  • 4 ½ cups powdered sugar
  • 2 teaspoons clear vanilla extract
  • 2-4 teaspoons non-dairy milk (I used almond milk), if needed
  • Stir in at the end – 6-8 crushed Oreos & about ½ cup of rainbow jimmies (NOT nonpareils; the color will dissolve and turn the frosting brown!)
Additional supplies / equpment:
  • - 1 8- or 10 -inch cardboard cake circle (I prefer Wilton’s center-punched circles)
  • - 1 cup chocolate chips + 2 Tablespoons vegetable shortening (for ganache drip – recipe below)
  • - Squeeze bottle OR piping bag OR spoon – whatever you’d prefer to add your ganache drip to the cake
  • - Squeeze bottle OR piping bag OR spoon – whatever you’d prefer to add your ganache drip to the cake
  • - Additional 8-12 Oreo cookies, whole – for decorating
  • Additional - 6-8 crushed Oreos & about ¼ cup of rainbow jimmies sprinkles, for decorating
  • - Cake leveler, cake turntable, large offset spatula, and pastry cutter/bench scraper - not all 100% necessary but incredibly helpful! (Links to my favorites are on!)
Cake layers:
Preheat oven to 350°F. Line four 7 inch pans (for taller layers) or three 8-inch cake pans with parchment rounds, and /or grease with non-stick or baker’s floured cooking spray.
Mix together all dry ingredients (flour, sugar, baking powder, and salt) in a stand mixer with a paddle until fully combined.
In a separate medium bowl, combine non-dairy milk, oil, vanilla, and lemon juice or apple cider vinegar and stir until well mixed.
Pour into dry ingredients and stir until just combined.
Stir in crushed oreos and rainbow jimmies – then I stirred as little as possible after this point, to keep the Oreo crumbs from turning my cake layers brown!
Divide batter evenly between the prepared cake pans (I find a kitchen scale helpful for this part). This guarantees your layers will bake to be the same height.
Bake for 20-28 minutes (or until a toothpick comes out clean). Allow cake layers to cool for 10-15 minutes on a wire cooling rack before removing from pans – it helps to run an offset spatula or knife around the perimeter of the pan first.
Cool completely before frosting. Set in the fridge or freezer to accelerate the cooling process if desired. This is a great time to make your frosting!
Cream together vegan butter and vegetable shortening until well-combined. Blend in powdered sugar alternating with vanilla extract (I added half at a time) adding almond milk if needed until a smooth and spreadable consistency is reached.
Gently mix in crushed Oreos and rainbow jimmies – stir as little as possible if you want your frosting to stay light in color!
Once your cakes are cool, level them (if needed/desired). This can be done with a cake leveler or a large serrated knife and a ruler. Place a smear of frosting on your cake circle (to keep the cake from sliding while you decorate it) and center your first cake layer in the center of the circle. Spread the layer with frosting. Repeat the process with your remaining cake layers.
Now you're ready to crumb-coat . If you're unfamiliar with crumb-coating, it's just what it sounds like – spreading a thin layer of frosting over the entire outside of the cake to keep crumbs out of your final layer. I usually do this with my large offset spatula.
Once your crumb coat has set (this takes about 5-10 minutes in the fridge), add your final layer of frosting and smooth. I like to use an offset spatula and bench scraper for this part. As I worked through this part I had to pull out a few larger Oreo chunks that were getting in the way of smoothing my frosting. Fill in the holes with a bit of extra frosting and keep smoothing.
Once your sides are smooth, set the cake in the fridge or freezer for 10-15 minutes to set the frosting and chill the cake so your ganache drip will set.
Meanwhile, make your ganache. Place 6 oz chocolate chips in a heat-proof bowl. Stir in 2 Tablespoons vegetable shortening and microwave on half power in 20-second intervals, stirring in between until melted and smooth.
When your ganache has cooled to a moderate temperature – it should feel slightly warm and still be fairly liquid – transfer it to a squeeze bottle or piping bag. A spoon will work if you don’t have either of those, I've  just found spoons to be a little bit more difficult to work with. Slowly drizzle ganache around the upper edge of your cake, pausing every inch or so to let more ganache fall in a drip down the side of the cake. Return cake to the fridge or freezer to set the drips.
Add several large frosting swirls to the top rim of the cake – I used my largest most-open star for this, so the Oreo chunks wouldn’t clog the piping tip. Space Oreo cookies in between the frosting swirls, add some crushed Oreos and sprinkles to the tip and base rim of the cake – and you’re done! Enjoy!
