How did I determine to develop this recipe? To begin with, I wished to make a vanilla sheet cake for a particular February birthday. And I discovered a copycat Costco sheet cake recipe on-line that I used to be content material to make use of with out having to develop my very own. Nonetheless, it was a complete catastrophe. I had an inkling that it might fail after studying by means of the recipe as soon as. However with a whole bunch of 5 star scores (and curiously, no written critiques) I attempted it anyway. After doing a little digging on Pinterest, and studying precise textual content critiques there, I found that I wasn’t the one one with horrible outcomes. That’s after I determined to take issues into my very own fingers.
Why Make your Personal Costco Vanilla Sheet Cake?
Should you reside in shut proximity to a Costco, then I perceive when you’d desire to only purchase one. Costco Sheet Truffles price $24.99 for a 12×16-inch cake that feeds 48 individuals. That’s a deal, when you ask me! Nonetheless, if – like me – you don’t reside close to a Costco anymore – this recipe could also be a priceless useful resource. Additionally, in 2020 when of us weren’t gathering as a lot, Costco stopped promoting their massive sheet desserts for some time. However fortunately, they’re again. And hopefully that can by no means occur once more! (Nonetheless chances are you’ll need to bookmark this recipe simply in case.)
Make the White Cake Layers
First, combine all of the dry elements within the bowl of an electrical mixer: flour, sugar, baking powder, and salt. Then, add room temperature butter to the dry elements and blend till the elements resemble high quality cornmeal. That is referred to as ‘reverse creaming’. It might sound unusual, nevertheless it’s a tried-and-true technique that harks again to the 1950’s. However all you really want to know is that it creates a fluffy cake with a young crumb. As soon as the moist elements are added, which incorporates 8 egg whites and a couple of entire eggs (add an additional dozen to the procuring listing!) the batter turns into thick and easy. Divide the batter into two 9×13 inch cake pan with sides at the very least 2 inches deep.
Bake and Cool the Cake Layers
Bake the desserts for about Half-hour, or till golden on prime and set of their facilities. Flip them out on wire racks to chill fully. You’ll discover the facilities don’t crown or dome an excessive amount of. That is one other advantage of reverse creaming. There may be little or no leveling to do after the desserts are baked. Some, however not a lot.
When the desserts are cool, refrigerate them for a few hours. This companies the crumb and makes them a lot simpler to degree with a serrated knife.
Make the Vanilla Cheesecake Filling
Within the bowl of an electrical mixer, beat collectively cream cheese and heavy cream on low pace. You’re not making an attempt to whip the heavy cream, you’re simply combining the 2 elements. Subsequent, beat in somewhat entire milk and a bundle of prompt vanilla pudding. Then, increase the mixer pace to excessive and beat till thick and fluffy. This mixture of elements creates a stunning, easy, not-too-sweet filling that tastes an entire lot like its inspiration!
High one cake with your entire quantity of cheesecake mousse filling, then prime with the second white cake layer.
Vanilla Buttercream Frosting
Cowl the cake in a traditional American buttercream. This method is simply butter, confectioners’ sugar, vanilla extract, and somewhat milk to skinny. The trick to creating this sort of buttercream billowy and lightweight, is to beat the heck out of it on excessive pace. I like to recommend a stand mixer for this. A sturdy hand mixer may additionally work however will take a very long time.
Pipe a Shell Border
Whereas décor will at all times range on the Costco Vanilla Sheet Cake, there’s at all times one ornament that may be a mainstay: a piped border. Use a big open star tip (corresponding to Ateco 826) to pipe a shell border alongside the underside and prime edges of the cake. If utilizing sprinkles to brighten, sprinkle them on instantly after piping one edge. As a result of the buttercream crusts simply, when you wait to lengthy they’ll bounce proper off.
Add Decors to Match Your Occasion
This cake is an all-occasions type of cake. In order I discussed earlier, the decors are as much as you! Purple, white, and blue for July Fourth. Purple and inexperienced for Christmas. Or any combination of comfortable sprinkles for a birthday-friendly cake (corresponding to these neon baubles).
I added a pink ‘Pleased Birthday’ candle to the middle of the cake. As a result of my finer piping expertise should not the perfect (I’m actively engaged on enhancing – however oof! It’s laborious.) I couldn’t discover the precise candle topper I used, however you will discover the same one proper right here.
Pleased Every little thing!
Occasion Cake Slicing Information
This cake is barely smaller than the 12×16 Costco cake, at 9×13-inches. Nonetheless, it’s nonetheless a sizeable confection! With two white cake layers, and the filling – it’s hefty. And you’ll tailor your slices to the dimensions of your occasion utilizing my information beneath. Giant Occasion Measurement Slices are beneficiant certainly, and would almost feed 2 individuals as a substitute of 1. The Medium Measurement Occasion Slices are extra in line with what I’d take into account a traditional serving. Nonetheless the Small Marriage ceremony Measurement Slices are loads adequate for a bigger occasion, and never skimpy-looking on a dessert plate.
This sizeable nook piece reveals off the pale fluffy layers and cheesecake filling. The cake slices so fantastically and has a young, fluffy crumb. Taste-wise it’s easy and mellow with vanilla, though with extra scratch-made taste than the unique Costco White Vanilla Sheet Cake. The filling is sort of near the unique – not overly candy, actually easy and creamy. Whereas the buttercream frosting is the visitor that brings the sweetness to the occasion.
This cake isn’t troublesome to make, and most dwelling bakers may have a few 9×13 pans of their bakeware arsenal. Use two an identical pans if doable, which is able to forestall additional trimming as soon as assembled. Try the reverse creaming technique in my video when you’re not accustomed to the approach.
