Halloween Candy Corn Sheet Cake

This Halloween Candy Corn Sheet Cake is made with a Halloween funfetti vanilla cake and a vanilla bean buttercream. It doesn’t taste like candy corn but the look of the cake does. I believe this is an easy cake for you guys to make and would totally impress your family and friends this Halloween!

WHAT YOU NEED TO MAKE THIS SHEET CAKE

• All Purpose Flour: Will give the cake the structure you need. For a softer and fluffier cake texture you can use cake flour. If you can’t find cake flour a good substitute is for every cup of all purpose flour add 2 tablespoons of cornstarch.
• Sugar: Adds sweetness.
• Salt: Adds flavor. I like using sea salt or pink Himalayan salt.
• Baking Powder & Baking Soda: Helps the cake rise. Aways double-check that your baking powder and soda are fresh and not expired.
• Butter: I recommend using unsalted butter because you are able to control the amount of salt you want especially when making the frosting. Be sure to bring the butter to room temperature. I always take mine out a couple hours before I want to bake. It must be soft enough so your finger leaves a dent when pressing it. If you forgot to take your butter out to come out to room temperature you can also zap it in the microwave for about 20 seconds. Do not melt the butter completely.
• Pure Vanilla Extract: Gives flavor! I get my favorite pure vanilla extract from Costco.
• Buttermilk: Make sure you bring the milk to room temperature. Avoid lower fat or nonfat milks. Milk with fat will give you the best flavor and add moisture to the cake. If you don’t have buttermilk, you can make a DIY sour milk substitute. Add 2 teaspoons of white vinegar or lemon juice to a liquid measuring cup. Then add enough whole milk to the same measuring cup until it reaches 1 cup. (In a pinch, lower fat or nondairy milks work for this soured milk, but the cake won’t taste as moist or rich.) Stir it around and let sit for 5 minutes. The homemade “buttermilk” will be somewhat curdled and ready to use in the recipe.
• Sour Cream: Makes cakes moist! Make sure sour cream is at room temperature. I would suggest removing from the fridge an hour or so ahead of time.
• Eggs: Make sure you bring the eggs to room temperature so they can effortlessly mix into the batter without over mixing.
• Halloween Sprinkles (optional)
• Candy Corn (optional)
• Edible Glitter (optional)

WHAT INGREDIENTS YOU NEED TO MAKE VANILLA BEAN BUTTERCREAM

• Butter Unsalted
• Salt
• Pure Vanilla Extract & Vanilla Bean Paste:  Vanilla bean paste is a game changer in recipes. If you do not have vanilla bean paste it’s not the end of the world, you can substitute with pure vanilla extract. My favorite brand for vanilla bean paste is Nielsen-Massey and you can find it on Amazon. I believe Trader Joe’s also sells their own vanilla bean paste too!
• Heavy Cream: You can also use whole milk if you do not have heavy cream on hand.
• Powdered Sugar: Also called confectioners sugar. PS- you do not need to sift it!

WHAT SUPPLIES YOU NEED

• Pipping Bags: I get mine from Amazon.
• Pipping Tip: 1M pipping tip. I get mine from Michaels.
• Food Coloring: You can use your favorite food coloring but I enjoy using Americolor color gel and Colour Mill Oil Based food colouring. You can find both on Amazon.
• 9×13 Inch Pan: Metal, glass or disposable pan is fine. Either will do. I love using Fat Daddio pans.

HOW TO MAKE FUNFETTI VANILLA SHEET CAKE

Preheat the oven to 350°F. Generously grease a 9×13 inch cake pan.

In a large bowl using a hand-held mixer or stand mixer fitted with a paddle attachment, cream the softened butter & sugar on medium speed and beat until light and fluffy in color. Beat in eggs and vanilla until smooth. You’ll need to stop the mixer and scrape down the sides and up the bottom of the bowl to get it all mixed a couple times. Beat in the sour cream on medium high speed until combined.

In a large bowl, whisk the flour, baking soda, and salt together.

Pour half of this flour mixture into the creamed butter mixture. Beat on low speed for 5 seconds. Pour in half of the milk. Beat on low speed for 5 seconds. Repeat with the rest of the flour and beat in the remainder of the milk until combined and smooth. Fold in the sprinkles. Do not overmix. Pour the batter into the prepared pan.

HOW TO MAKE VANILLA BEAN BUTTERCREAM

Using a hand-held mixer or stand mixer fitted with a paddle or whisk attachment, beat the butter on medium speed until light and fluffy, about 2 minutes. Add vanilla extract, vanilla bean paste, heavy cream and salt with the mixer running on low. Slowly add the powdered sugar. Increase to high speed and beat for 3 full minutes. You can add more powdered sugar if frosting is too thin, more cream if the frosting is too thick, or a little more of salt if the frosting is too sweet. Yields about 6 cups of frosting.

HOW TO DECORATE THE CAKE

Split the buttercream evenly into three bowls (about 2 cups each). Tint one bowl orange and one bowl yellow. The third bowl remains white. I used Orange & Yellow Colour Mill Oil Based food colouring.

I like to use a large cup to help with adding the frosting to each pipping bag.

Place about a cup of frosting in each pipping bag. You should have 3 bags (orange, yellow, white).

Cut off the tips of the bags.

Next, get another pipping bag and place a 1M pipping tip in the bag and cut off the tip of the bag. I have three 1M pipping tips but you guys probably don’t have that many. It’s okay if you just have one. You’ll just have to wash the tip each time you change out the color of the frosting.

Place the yellow bag of frosting in the bag that as your pipping tip.

Start decorating at the bottom of the cake. Work your way from left to right and repeat until you get about 1/3 way up the cake.

Now take your pipping bag filled with orange frosting and place it in another bag with a 1M pipping tip. If you only have one 1M pipping tip just remove it, wash it, and place it in a new pipping bag. Pipe the design like you did with the yellow frosting, working your way from right to left. Repeat until you get about 3/4 the way up cake.

Finally, take your pipping bag filled with white frosting and place it in another bag with a 1M pipping tip. Again, if you only have one 1M pipping tip just remove it, wash it, and place it in a new pipping bag. Pipe the design like you did with the yellow and orange frosting, working your way from right to left. Repeat until you get all the way up cake. If you’d like to take your decorating up a notch add candy corn, sprinkles, and/or gold edible glitter like it did.

Ta-da! You are all done!

Slice and serve. Cover and store leftover cake at room temperature for up to 3 days or refrigerate for up to 5 days.

TIPS FOR MAKING THIS RECIPE

• Do not over-mix the batter as you risk over-developing the gluten leading to a tough, dry, and dense cake.
• All refrigerated items should be at room temperature so the batter mixes together easily and evenly.
• Make sure to allow the cake to cool before you add the buttercream.
• Make sure the butter is room temperature before you cream it, as cold butter will lead to lumpy buttercream.
• The longer you chill the cake, the better the buttercream will stick to the cake layers.

FREQUENTLY ASKED QUESTIONS

Can I make this cake in advance?

Yes! You can make the cake and buttercream frosting a few days ahead of time and keep them tightly wrapped in the fridge, then assemble them when you’re ready. You will need to pull out your buttercream from the refrigerator a few hours before you’d like to decorate to bring it back to a spreadable consistency. I would suggest once the buttercream has softened whip it up in your mixer before adding it to your pipping bags to decorate. You can also make the entire cake in advance, wrap and place it in the fridge for up to 5 days.

Can I turn this recipe into a 2 layer cake?

Yes! Grease two 8 or 9 inch round cake pans (which ever size you have on hand), line with parchment paper rounds, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans. Divide the batter evenly between the pans. Bake time will be a few minutes shorter—keep a close eye and check for doneness with a toothpick.

Can I turn this recipe into a bundt cake?

Yes! Grease your bundt pan with. Bake time will be a few minutes longer—keep a close eye on the cake at 20 minutes and check for doneness with a toothpick.

Can I turn this recipe into cupcakes?

Yes! Using a cupcake pan fill cupcake liners 2/3 full. I love using this baking scoop for my regular sized cupcakes and this baking scoop and mini cupcake liners for my mini cupcakes. Bake at 350°F for 18-20 minutes. Yields about 2 dozen regular sized cupcakes.

What kind of sprinkles can I use for adding to the cake mix?

I always use jimmie sprinkles when adding to cake batter. You can find these on Amazon.

Avoid nonpareils (the little balls pictured below), which tend to bleed their color. These would go great on top of the cake though!

Do I need to add sprinkles to the cake batter?

Of course not. You can totally leave them out. Another fun thing you can do is color the cake batter! You can do one color or multiple colors and make a marble effect. You can see how to make a marble effect cake here.

Can I make this with store bought cake mix?

Yes! You can use any vanilla or funfetti store bought cake mix. Follow the directions on the cake box to mix all the ingredients. Bake according to the directions on the box.

Can I make this with store bought frosting?

Yes! You can use any vanilla store bought frosting. I would suggest using 2 to 4 containers of the store bought frosting. Proceed to Step 7 on directions on how to color frosting and decorate the cake.

How do I store leftover frosting? 

Buttercream frosting can be stored in the refrigerator for at least seven days. Just be sure that the container is tightly sealed and that you keep the frosting far from pungent foods like seafood since the smells can transfer. You can also freeze buttercream frosting for up to 3 months in an airtight container or freezer bag. The day before you’re ready to use it, let it thaw in the refrigerator overnight, then bring it to room temperature before re-whipping again. This is helpful if you’re making buttercream months in advance, or you have leftover frosting you’d like to use later on.

How do I store cake leftovers? 

Cover and store leftover cake at room temperature for up to 3 days or refrigerate for up to 5 days. You can also freeze frosted cake or unfrosted cake can be frozen up to 2-3 months. Make sure to throughly wrap with plastic wrap and aluminum foil. Thaw overnight in the refrigerator and bring to room temperature before decorating/serving.
