Apple Slab
Hubby and I did some apple picking a couple weeks ago. We didn’t want our bounty to go to waste, so I immediately remembered this recipe which I had saved off. I’m not sure if you remember me mentioning this, but the lovely people at King Arthur Flour have a baking hotline. Now I’d say I’m a pretty confident baker. But that’s mostly because I know how to follow a recipe. The minute I change things up, I lose some of that confidence. That’s where the hotline comes in.
I wanted to make this apple slab while I had the delicious apples on hand, but I wanted to freeze it and bake it later. I figured I’d shoot the KAF Baking Hotline an email to see what they recommended. I was shocked how quickly they got back to me. Within a few hours, they confirmed that I could assemble the slab and freeze it. Then they said when I go to bake it, just put it straight into the oven from the freezer and add 15-20 minutes to the baking time. Just like that, I had input from an expert and all my worries went away. I love how they got back to me so quickly! Definitely give them a try next time you’re in a baking pickle.
Now back to the slab. No surprise here, this tastes just like apple pie. But I think it’s better than apple pie. Why? For one, it’s portable. You don’t need a fork and plate to eat a piece, just use your hands. Second, it’s less of a committment than a slice of pie. Around the holidays, I often have the issue where my eyes are bigger than my stomach. The smaller pieces let you try some of the apple slab without committing to a big piece. And if it’s your favorite dessert of the day, you can go back for another piece.
I’m going to be making another one of these real soon to throw in my freezer. Then I’ll have a perfect holiday dessert for the upcoming parties, potlucks, and get-togethers. One note though, the crust was much crispier the first day it was baked. It did get a bit soggy the next day. Be sure to leave off the glaze until you are going to serve it.
Also, I didn’t have panko bread crumbs or corn flakes. I planned to sub oats, but didn’t have those on hand either. Instead I used graham cracker crumbs and they worked just fine.

Apple Slab
Yield: 24
Ingredients:
For the Crust
2 1/2 cups flour
1 tsp salt
1 tsp baking powder
2 Tbsp confectioners' sugar
2 Tbsp buttermilk powder
1/4 cup vegetable shortening
10 Tbsp very cold unsalted butter
1 tsp vinegar, cider or white
6 to 10 Tbsp ice water
For the Filling
1 cup Panko bread crumbs, cornflakes, or graham crackers
8 cups peeled, cored, and sliced Granny Smith or other tart, firm apples, about 6 large apples
2/3 cup cinnamon sugar
For the Glaze
1 1/2 cups confectioners' sugar
1/3 cup boiled cider or honey
small pinch of salt
1/2 tsp ground cinnamon
1 tsp milk or cream, optional, if necessary to thin the glaze
Directions:
For the Crust
Whisk together the flour, salt, baking powder, confectioners' sugar, and buttermilk powder.
Add the shortening, working it in till the mixture is evenly crumbly.
Cut the butter into small (about 1/2") cubes. Add the butter to the flour mixture, and work it in roughly with your fingers, a pastry cutter, or a mixer. Don't be too thorough; the mixture should be very uneven, with big chunks of butter in among the smaller ones.
Add the 1 teaspoon vinegar and 4 tablespoons water, and toss to combine. Toss with enough additional water to make a chunky, fairly cohesive mixture. It should hold together when you gather it up and squeeze it in your hand.
Divide the dough into two pieces; one should represent about 40% of the dough, the other, about 60%. If you have a scale, this is easy; the smaller piece of dough should weigh about 8 3/4 ounces, the larger piece, about 13 1/4 ounces (if you've used about 7 to 8 tablespoons of water in the dough). If you don't have a scale and/or aren't good at math, eyeball it: the bottom crust needs to be larger than the top crust.
Shape each piece of crust into a rectangle; you're going to be rolling them into rectangles, so might as well give yourself a head start. Cover with plastic wrap, and refrigerate for 30 to 60 minutes, till thoroughly chilled.
Take the larger piece of pastry out of the fridge, and put it on a floured work surface. Roll it into an 11" x 15" rectangle. Don't worry about the ragged edges; they'll disappear under the top crust.
Place the crust in an ungreased 9" x 13" cake pan. Patch up any holes by pushing the pastry together with your fingers, or adding a pinch from the excess on the sides. Push the pastry up the sides of the pan a bit, to make a shallow pastry container for the apples.
Put the crust in the fridge while you get the apples ready. Start preheating your oven to 350°
To Assemble
Spread the bread crumbs evenly over the crust.
Spread the sliced apples atop the crumbs.
Sprinkle the cinnamon sugar over the apples.
Roll the remaining piece of pastry into a 9" x 13" rectangle. Again, don't worry too much about ragged edges.
Lay the top crust over the apples. Yes, apples will poke through. Seal the edges of the two crusts as well as you can. There'll be places where they don't quite meet. That's OK. If the whole thing has become warm and sticky and hard to work with, pop it in the fridge for 15 minutes to firm it up.
Just before baking, slash the crust 6 or 8 times to allow steam to escape.
If freezing for later, freeze at this point. When ready to bake, place frozen slab directly into oven and bake for an addition 15-20 minutes.
Put the slab in the preheated 350°F oven, and bake it for an hour. Remove it from the oven; it'll be golden brown, and the filling should be bubbling. Remove it from the oven, and allow it to cool completely before glazing.
For the Glaze
Combine the confectioners' sugar, boiled cider, cinnamon, salt, and enough milk or cream to make the mixture "drizzlable." Don't have boiled cider? Use plain milk or cream, maple syrup, honey, or thawed apple juice concentrate. Start with 1/4 cup of any of these; if you've made this kind of icing before, you know it's easier to add more liquid, than to try to take it away. Add enough liquid to make the glaze pourable.
Drizzle the glaze atop the slab.

I am Jen the Beantown Baker. Engineer by day and baking maven by night. Hubby serves as my #1 fan and official taste tester. We got hitched back in 2006. Barefoot. In the sand. With the waves crashing behind us. It was one of the best decisions we’ve ever made. 
Raspberries are my very favorite food on the planet and this looks absolutely divine. Thanks for sharing this!
Its my husband birthday on Fri I might try to talk him into having this cake for it.
awesome work, Jen! It sounds delicious and looks gorgeous. I’m totally jealous of your border-piping skills too.
Beautiful cake! This is very similar to our wedding cake, I may just have to try it!
It looks beautiful and sounds delicious. I’ll have to try this one!
This looks absolutely terrific! Great job on the assembly and decoration!
really beautiful cake! and raspberries are one of my favorite fruits ever! i love the little sacs together with the crunchy seeds. hee.
Holy beautiful! this cake is quite elegant and delicious looking! I love raspberries with cake.
Jen this cake is so so beautiful! It reminds me of the triple berry cake from Sweet Lady Jane here in LA. If an opportunity every arises for me to make a layer cake (I have the same problem – it’s hard to find people to help finish it!) I will definitely try this one.
You did a beautiful job with the piping. Gorgeous.
We should be best friends hahaha. We have the same go-to white cake recipe, and we both made layered cakes this weekend! Your cake is BEAUTIFUL! You have every right to brag. You did an excellent job on the piping and decorating. It looks professional!
I added lemon extract to my strawberry frosting on my strawberry cake (which came from Bridget’s recipe), and I could taste hints of lemon. I think the extract and some lemon zest would work well.
I must make this cake!! I am 100% certain that I would like it because we have similar tastes.
Now I need to look at your overdose cake to compare it to my overload cake.
Lemon and raspberries sounds like a perfect flavor combo. Your cake looks beautiful!
OH wow, I started drooling as soon as I saw the pic. SO pretty and looks delish! Will def. have to try this one… 🙂 Thanks for sharing!
This is so, so pretty! And obviously looks delicious too. Raspberries are one of my favorite parts of spring!
Sues
I don’t think you’re bragging! I would be proud of a beautiful cake like this one.
Looks delicous!

beautiful!! Great decorating job!
This cake looks awesome and my mouth is watering looking at the picture right now.
beautiful cake!
This cake is SO, SOOO beautiful! I love it!!!
Looks beautiful, I love layer cakes!
you say something about videos from youtube? can you share the the links?
vertigoxcured – I updated the post with links to the youtube videos. Sorry about that.
I made this for Mother’s Day and it was a huge hit! Thanks for sharing. I added the juice of the zested lemon and an extra cup of confectioners’ sugar to the buttercream and managed to get a nice lemony tang.
I cant believe this is your first frosting coated cake. So beautifully done. And also note…that 4 layers with fruit filling without cake sliding all over the place is not a normal for first timers in that department. Kudos… you got the cake decorating skills Ma’am.
am making this cake right now, and i must ask about the proportions of flour to liquid. it seems off. i made the recipe exactly as written and it was a pool of liquid. i had a similar recipe for a white cake which called for 2-3/4 flour and only 4 egg whites + 1 whole egg ( similar), so i added another 1/2 cup flour and it was still liquidy. it took 30 mins. to bake, not 23-25. will see how it turns out. the only good part is rubbing the grated lemon zest with the sugar, although i could not taste much lemon in the batter. by the looks of the layers, i would recommend 8″ pans as the layers are quite thin. all in all a big disappointment. glad i planned ahead and will make a different recipe.

Sorry to hear this recipe didn’t work out for you. This batter was very thin going in to the oven.
Does this cake keep well? i just made three 6″ cakes, which I’ll freeze in preparation for making a little layer cake on Sunday (a top-tier wedding cake replacement for our one year anniversary, after Hurricane Sandy ruined the real one.) But I also made two dozen cupcakes with the batter. I’m planning to bring one dozen to a dinner party tomorrow and the next dozen to a party on Wednesday. Any tips for the cupcakes? Should I freeze them, or just leave them out til I’m ready to frost? Would appreciate any suggestions! Thanks.

I haven’t made this cake into cupcakes before. But in general, cupcakes are fine for a couple days. If it’s more than 2-3 days, I’d go ahead and freeze them, then frost them the day before you want to serve them.
Would it be advantageous to whip the egg whites first, and fold them into the batter at the end? It might help with the thin batter issue, and I have some recipes for white cake that call for whites whipped into soft peaks. I am making this cake for a baby shower this weekend, so I will let you know how this technique works, unless the author has an opinion against.
beantownbaker — June 10th, 2013 @ 12:27 pm
I have made this cake, or a variation of the cake, multiple times as it is written without any issues. I know some cake recipes do have the cake whites whipped and folded in at the end. If you try it, please let me know how it goes.
If you could email me with a few pointers on how you made your blog site look this cool, I would be thankful!
Going to endeavor to make this for my husband’s birthday next weekend. I haven’t made a cake in ages, but I like challenges!!! Hopefully it will go well as his parents are coming into town for his birthday (yikes!) I hope it has a nice lemon flavor because he loves lemon. Wish me luck!!!
beantownbaker — September 27th, 2013 @ 3:54 pm
I hope he enjoys it. The cake definitely has a lemon flavor. If you wanted to go super lemony, you could use lemon curd instead of raspberry curd for the filling!
Cake looks beautiful. However, each cake was an only an inch thick so was confused how to possibly cut it in half to make four layers. So after everything was cleaned up, I had to make a second round of this. The puree was tasty and plenty of it. The Frosting was delicious and plenty also. The cake itself tasted good with hint of lemon, but did not rise much at all and it had a very rubbery texture and very dense. I agree the batter was thin when I poured in pans, but it was not fluffy and light by any means after it was baked. I appreciated making it, but not a fav for me.
I know this is an old post, but I had to comment after making it for the first time yesterday. This is a lovely cake! The only downside, for me, was that the lemon flavor was lighter than I thought it would be. I ended up topping it with some toasted almonds and fresh raspberries, and serving it with homemade coconut ice cream.
*Note: My layers came out quite thin. They were both only a little over an inch thick, and the batter itself was a slightly thick/fluffy consistency. That being said, I was able to torte them without difficulty and the finished cake came out to a little over 3 inches.
