How To Make

Creating this spectacular sheet cake is easier than you think once you break it down into manageable steps. Let me guide you through making perfect Oreo Ding Dong Sheet Cake every time.

Prepare the Pan

Preheat your oven to 175 degrees Celsius or 350 degrees Fahrenheit for your Oreo Ding Dong Sheet Cake. Make sure the oven is fully preheated before baking.

Grease a 10 by 15 inch jelly roll sheet pan generously with nonstick baking spray for your Oreo Ding Dong Sheet Cake. Make sure all surfaces including corners are well coated.

Mix Dry Ingredients

In your stand mixer bowl, combine the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking soda, baking powder, and kosher salt for your Oreo Ding Dong Sheet Cake. Mix briefly on low to combine.

Combine Wet Ingredients

In a separate bowl, whisk together the buttermilk, vegetable oil, eggs, and vanilla until smooth for your Oreo Ding Dong Sheet Cake. Mix just until blended with no egg streaks visible.

Make the Batter

With the mixer running on low speed, slowly pour the wet mixture into the dry ingredients for your Oreo Ding Dong Sheet Cake. Once incorporated, pour in the hot coffee and mix on low just until combined.

Scrape the bottom of the bowl with a spatula to catch any dry pockets for your Oreo Ding Dong Sheet Cake. Do not overmix or the cake will be tough.

Bake the Cake

Pour the batter into the prepared pan and spread evenly for your Oreo Ding Dong Sheet Cake. Make sure it covers the entire pan.

Bake for 28 to 30 minutes until a toothpick inserted in the center comes out mostly clean with no wet batter for your Oreo Ding Dong Sheet Cake. The top should look set.

Let the cake cool completely at room temperature for your Oreo Ding Dong Sheet Cake. Then transfer to the freezer or refrigerator until fully firm. This takes about 2 to 3 hours.

Make Oreo Ermine Filling

Whisk the milk and flour together in a medium saucepan over medium heat for your Oreo Ding Dong Sheet Cake filling. Cook, whisking constantly, for 3 to 5 minutes until the mixture thickens into a very stiff pudding-like paste with no lumps.

Remove from heat and cool completely to room temperature for your Oreo Ding Dong Sheet Cake. This step cannot be rushed.

Beat the butter and sugar together in your stand mixer with the paddle attachment on medium speed for 2 to 3 minutes for your Oreo Ding Dong Sheet Cake filling. Beat until very light and fluffy. Scrape down the sides.

Add the fully cooled milk paste and beat on medium-high for 2 to 3 minutes for your Oreo Ding Dong Sheet Cake. Beat until fluffy. Switch to the whisk attachment.

Add the vanilla and whip on high speed for 7 to 8 minutes for your Oreo Ding Dong Sheet Cake filling until perfectly smooth and silky. Set a timer and trust the process.

Remove the bowl from the mixer and fold in the finely crushed Oreo crumbs by hand with a spatula for your Oreo Ding Dong Sheet Cake. Fold until evenly distributed throughout.

Make Chocolate Ermine Frosting

Repeat the same milk and flour paste process for your Oreo Ding Dong Sheet Cake frosting. Cook whisking constantly until a very stiff paste forms. Remove from heat and cool completely to room temperature.

Beat the butter, sugar, and cocoa powder together in the stand mixer with the paddle attachment on low speed for your Oreo Ding Dong Sheet Cake. Beat until the cocoa is fully incorporated. Then increase to medium and beat until light and fluffy for 2 to 3 minutes.

Scrape down the sides of the mixer bowl for your Oreo Ding Dong Sheet Cake frosting. Add the cooled milk paste and beat on medium-high for 2 to 3 minutes until fluffy.

Switch to the whisk attachment and add the vanilla for your Oreo Ding Dong Sheet Cake frosting. Whip on high speed for 8 to 10 minutes until completely smooth and creamy. These minutes are crucial for perfect texture.

Assemble the Sheet Cake

Remove the fully chilled cake from the freezer for your Oreo Ding Dong Sheet Cake. Using a long serrated knife, slice the cake in half lengthwise to create two equal rectangles of identical size.

Place one rectangle flat on a large serving board or platter for your Oreo Ding Dong Sheet Cake. Spread the entire Oreo ermine filling in a thick generous layer over the top surface. Go all the way to the edges.

Carefully place the second cake rectangle directly on top of the filling for your Oreo Ding Dong Sheet Cake. Press gently and evenly to adhere.

Spread the chocolate ermine frosting over the entire top surface for your Oreo Ding Dong Sheet Cake. Create generous rustic swirls covering edge to edge.

Decorate and Finish

Scatter the coarsely crushed Oreo pieces generously over the frosting for your Oreo Ding Dong Sheet Cake. Place the halved whole Oreos decoratively across the top.

Drizzle the melted white chocolate in a zigzag pattern over everything on your Oreo Ding Dong Sheet Cake. Create elegant presentation with the drizzle.

Refrigerate for at least 1 hour before slicing your Oreo Ding Dong Sheet Cake. Use a sharp knife dipped in hot water and wiped dry between each cut for clean edges.

How to Serve

This Oreo Ding Dong Sheet Cake is perfect for large gatherings, parties, potlucks, birthdays, or any celebration where you need to feed a crowd. Serve chilled straight from the refrigerator for best taste and texture. The cake slices beautifully to show off the chocolate layers with Oreo filling between them. Pair with cold milk, coffee, or vanilla ice cream for perfect combination. Store covered in refrigerator for up to 4 days. Let slices sit at room temperature 10 to 15 minutes before serving for optimal flavor. This makes 20 generous servings perfect for large groups.

Expert Tips

• Crush Oreos in two textures: Use food processor for finely crushed filling and zip-lock bag with rolling pin for coarser decoration topping for your Oreo Ding Dong Sheet Cake.
• Cool milk paste completely: Even slightly warm paste will melt butter and break ermine for your Oreo Ding Dong Sheet Cake. This step cannot be rushed.
• Room temperature butter essential: Cold butter will not whip up properly for your Oreo Ding Dong Sheet Cake. Take out at least 1 hour before starting.
• Don’t skip final whipping time: Those 7 to 10 minutes of high-speed whipping transform ermine from grainy to silky for your Oreo Ding Dong Sheet Cake.
• Freeze before slicing in half: A firm cold cake cuts cleanly for your Oreo Ding Dong Sheet Cake. Room temperature cake will crumble.
• Add Oreo decoration right before serving: Crushed Oreos soften overnight from frosting moisture for your Oreo Ding Dong Sheet Cake.
• Make ahead with confidence: Cake and ermine components can be made 24 hours ahead and stored separately for your Oreo Ding Dong Sheet Cake.
• Use stand mixer with paddle: Ermine requires proper equipment to achieve silky texture for your Oreo Ding Dong Sheet Cake.
