Ingredients of Smith Island Cake
When it comes to baking a show-stopping dessert, the ingredients are just as important as the technique, and the Smith Island Cake is no exception. This delightful cake combines the flavors of chocolate and peanut butter, all wrapped up in eight luscious layers.
It’s not just about throwing some stuff together; it’s about using quality ingredients to create something truly special. So, let’s take a closer look at what you’ll need to whip up this masterpiece.
Ingredients for Smith Island Cake:
- 8 large Reese’s Peanut Butter cups, frozen
- Nonstick cooking spray
- 1/4 cup flour (plus extra for dusting)
- 1 (18 1/4 ounce) box yellow cake mix (preferably Duncan Hines)
- 2 cups evaporated milk
- 3 tablespoons evaporated milk (for icing)
- 6 tablespoons butter, softened (plus more for the icing)
- 1 teaspoon vanilla extract (or double it for more flavor)
- 1/2 teaspoon salt
- 4 eggs
- 6 cups confectioners’ sugar
- 1/4 cup unsweetened cocoa
Now, let’s chat a bit about those ingredients. First, the choice of cake mix can really make or break your cake. I mean, who wants a dense and dry cake? Duncan Hines is pretty reliable, but feel free to experiment if you have a favorite brand.
And don’t even get me started on the peanut butter cups—frozen is key! Chopping them up while they’re frozen makes it easier, and who doesn’t love the crunch of peanut butter candy in their cake?
Also, using evaporated milk instead of regular milk adds a creamy richness that makes each bite feel indulgent. Finally, don’t skimp on the frosting ingredients; the icing is where the magic happens, and trust me, you’ll want those layers to be dripping with chocolatey goodness.
How to Make Smith Island Cake

Alright, let’s plunge into the delicious process of making a Smith Island Cake, shall we? First things first, you’ll want to get that oven preheated to a cozy 350°F. While that’s warming up, grab your 8 large frozen Reese’s Peanut Butter Cups and start the fun part—chopping them up! Use a food processor to pulse 4 of those cups into small chunks (because who doesn’t love a little crunch?) and then pulverize the remaining 4 into a fine powder. Set those aside in separate bowls and chill them until you’re ready to assemble your masterpiece.
Next up, let’s talk about the cake. Grab your 1 (18 1/4 ounce) box of yellow cake mix (Duncan Hines is the go-to here), and in a large mixing bowl, combine it with 1 1/2 cups of evaporated milk, half of your softened 6 tablespoons of butter, 1 teaspoon of vanilla extract (or double it if you’re feeling fancy), 1/2 teaspoon of salt, and 4 eggs.
Now, this is the part where you really want to beat that mixture well, using an electric mixer until it’s light and fluffy—about 10 to 12 minutes. It’s almost like a workout, but don’t worry, your cake will thank you.
Once your batter is ready, grease four 8-inch round cake pans with nonstick cooking spray and dust them with 1/4 cup of flour. Divide half of that luscious batter evenly into the pans, spreading it slightly thicker around the edges. Bake those bad boys for 12-14 minutes or until they look golden and cooked through.
After they cool a bit, gently loosen the edges with a knife and invert them onto cooling racks. Rinse and repeat with the remaining batter until you have all 8 layers baked and cooled.
Now, let’s get to the icing, because honestly, that’s where the magic really happens. In a medium pot, mix the remaining 3 tablespoons of evaporated milk, 6 cups of confectioners’ sugar, and 1/4 cup of unsweetened cocoa. Stir it up until it’s well-combined and then toss in the rest of your softened butter.
Cook this over medium heat, stirring constantly until the butter melts and everything gets shiny and smooth—about 4-5 minutes. Once it cools for a bit, you’re ready to layer. Spread about 1/4 cup of icing between each cake layer, sprinkling some of those peanut butter cup chunks in between, and then frost the outside with the remaining icing.
Let your cake sit for a good 2-3 hours before indulging; it really helps the flavors meld together. And there you have it, a glorious Smith Island Cake that’s sure to impress anyone lucky enough to get a slice. Enjoy the sweet chaos!
Smith Island Cake Substitutions & Variations
While sticking to the classic Smith Island Cake recipe is a surefire way to impress, experimenting with substitutions and variations can lead to delightful new flavors.
For a twist, I sometimes swap the yellow cake mix for chocolate or red velvet. You can also add a hint of almond extract instead of vanilla for a unique taste.
If you’re feeling adventurous, try incorporating crushed fruit, like strawberries or raspberries, between the layers.
For a nutty crunch, I love adding chopped nuts to the icing.
These variations keep the cake exciting and allow me to personalize it for every occasion!
What to Serve with Smith Island Cake
To elevate your Smith Island Cake experience, I love pairing it with a scoop of vanilla ice cream or a dollop of whipped cream.
The creaminess complements the cake’s rich chocolate and peanut butter layers perfectly. If you’re feeling adventurous, a drizzle of caramel or chocolate sauce adds a delightful touch.
Fresh berries, like strawberries or raspberries, provide a tart contrast that balances the sweetness. For a cozy twist, serve a warm cup of coffee or a spiced chai tea on the side.
These additions enhance the flavors and make every bite even more enjoyable for your guests!
Additional Tips & Notes
When preparing your Smith Island Cake, keep in mind a few key tips to enhance your baking experience.
First, make certain all your ingredients are at room temperature for better mixing. I like to double the vanilla for a richer flavor.
Don’t rush the cooling process; letting the layers cool completely guarantees a stable cake.
If you want a more intense chocolate flavor, try adding a splash of coffee to the icing.
Finally, storing the cake in the fridge allows the flavors to meld beautifully, and it stays fresh for about a week.
Enjoy every decadent bite!
