Strawberry Crunch Cake
Inspired by my childhood favorite ice cream bar, this Strawberry Crunch Cake is made up of my go-to strawberry and vanilla cake layers, strawberry crunch filling, whipped vanilla buttercream, and is covered in a shortbread cookie strawberry crunch.
This late winter in Utah has me aching to bypass spring and jump feet first into summer. We had snow a week ago, you guys! The second week of April! Simply uncalled for, if you ask me 😉 This California girl will never get used to what people call a Utah “spring.” It’s just an extra long winter. There’s no way to make that sound enjoyable.
As I’ve been dreaming of pool days, I’ve been thinking about new summer-inspired cake flavors I want to whip up. Last year I did a Watermelon Lime Cake, a Root Beer Float Cake, and a Rainbow Sherbet Cake, to name a few. I loved how each one of them turned out. I couldn’t help but think back to my childhood with each bite.
This year, I’m returning to memory lane with my childhood favorite summer treat, the Strawberry Crunch Bar.
Strawberry Crunch Cake
As I thought about turning this yummy treat into a cake, I knew I didn’t want it to have ice cream. (Just goes against everything I stand for ;). ) I wanted to make sure, however, that it had all the same flavors as the bar. It needed to be the perfect blend of strawberry and vanilla with a little crunch.
I looked at Pinterest to see how often this cake has been made and to my surprise, I only found a few layered cakes similar to what I had in mind. One of the cakes that caught my attention was from Confessions of a Cookbook Queen. Her version of this cake was very similar to what I envisioned for my cake: layers of strawberry and vanilla cake with a yummy strawberry crunch coating. I immediately felt like soul sisters 😉
My Version
For my version, I whipped up a half batch of my vanilla cake (the base of my Funfetti Cake) and a half batch of my Strawberry Cake. I then made my Strawberry Frosting and threw in some freeze-dried strawberries to give it a little texture and flavor dimension.
For the vanilla frosting, I adapted the vanilla frosting from the Milk Bar Birthday Cake. I love how light and fluffy it is and thought it would pair well with the slightly denser strawberry filling. 
As for the outer layer of crunch (or crack, as some might say), I toasted shortbread cookie crumbs and then mixed in chopped up freeze-dried strawberries. You’ll have some leftovers of this, but don’t throw it away. I always save any extra fillings to serve alongside the cake.
The layers of cake are tender and fluffy and full of flavor. And I love how the two frostings complement each other with different textures and flavors.
It’s a summer cake worthy of your reliving childhood memories. I hope you love it as much as I do!
And here’s a little behind-the-scenes of how I put together this cake.
Enjoy!

Instructions
FOR THE STRAWBERRY CAKE
- Preheat your oven to 350 degrees F. Prepare four 6-inch round cake pans by spraying each pan with non-stick spray, covering the bottom of the pan with parchment paper, and spraying the parchment paper with the non-stick spray as well. Set aside.
- In the bowl of an electric mixer fitted with the paddle attachment, combine the cake flour, sugar, Jell-O, baking powder, and salt. Stir to combine.
- Add the cubed butter, one piece at a time, and 1/2 cup of buttermilk to the dry ingredients. Beat on medium-low speed until light and fluffy. About 2 minutes. Scrape down the sides of the bowl.
- In a small mixing bowl, whisk the egg whites and remaining 3 tablespoons of buttermilk. Add the mixture to the mixing bowl in 2 separate additions, mixing for about 30 seconds and scraping down the sides of the bowl in between each addition. Mix in the vanilla.
- Divide the batter evenly between two of the four 6-inch pans (about 12 ounces of batter in each pan). Bake for about 15 minutes.
- Let cool in the pans for about 10 minutes and then invert onto wire cooling wraps to cool completely. Cakes can be individually wrapped in plastic wrapped and frozen for a week. If you'd like to freeze them longer than one week, wrap each cake layer in tin foil as well. Level the layers before freezing, if needed.
FOR THE VANILLA CAKE
- In a medium-sized mixing bowl, combine the egg whites and clear vanilla extract. Set aside.
- In the bowl of a stand mixer fitted with the paddle attachment, combine the cake flour, sugar, baking powder and salt. Mix on low speed for about 30 seconds.
- With the mixer on low speed, add the butter and buttermilk. Continue to mix on low until just combined and then increase to medium speed and mix for 1 to 2 minutes, until light and fluffy.
- Scrape down the sides of the bowl and add the egg mixture in two additions, beating on medium speed for about 20 seconds after each addition until just combined and all the ingredients are thoroughly incorporated.
- Divide the batter into the remaining two 6-inch pans, using a kitchen scale to measure equal parts in each pan. (About 12 ounces of batter).
- Bake for 15 minutes, or until a toothpick inserted into the center of the cake comes out clean.
- Let the cakes cool in the pans for 10 minutes and then invert onto wire racks until completely cool.
FOR THE STRAWBERRY FILLING
- In the bowl of a stand mixer, beat the butter for 2 minutes until light and fluffy.
- With the mixer on low speed, gradually add the powdered sugar, followed by the strawberry emulsion.
- Add the whipping cream and turn the mixer to medium-high and beat for another 2 to 3 minutes.
- Fold in the freeze dried strawberries.
FOR THE BUTTERCREAM
- In the bowl of a stand mixer, combine the butter, shortening, and cream cheese and beat together on medium-high for 2 to 3 minutes, until the mixture is smooth and fluffy.
- With the mixer on its lowest speed, add the powdered sugar and vanilla. Increase the speed back up to medium-high and beat for 2 to 3 minutes, until you have a nearly white frosting.
- Remove the bowl from the mixer and use a wooden spoon and mix by hand to stir out the air bubbles.
FOR THE COOKIE CRUNCH
- Preheat your oven to 300 degrees F. Line a baking sheet with parchment paper. Set aside.
- In a food processor or blender, pulse the shortbread cookies until they are crumbs. Add the melted butter and mix until combined.
- Bake the crumbs for 15 minutes. Let cool completely.
- In a medium sized bowl, combine the toasted shortbread cookie crumbs and freeze dried strawberries.
ASSEMBLY
- Level each cake layer, if needed, and then place one of the vanilla cake layers, crumb side up, on a cake board that has a little smear of frosting on it.
- Spread half 1/3 of the strawberry filling over the vanilla cake layer. Place a strawberry cake layer on top of the filling and spread another 1/3 of the filling over the strawberry cake layer. Repeat for the second vanilla cake layer, and then place the final strawberry cake layer, crumb side down, on top.
- Cover the entire cake with a thin layer of vanilla frosting. Freeze the cake for about 10 to 15 minutes to set the crumb coat and lock the crumbs into place.
- Finish frosting the cake with the remaining vanilla frosting and the cover the entire cake in the shortbread cookie strawberry crunch.
Will I have to double the filling recipe if I make 3 layer 9 inch cake?
1.5x the filling recipe.
I’m wanting to make this in 8in pans. Would I need to double the any thing?
Yes, if you want the same thickness of cake layers, you’d want to 1.5x the recipe for four 8″ pans.
seems delish!! attempting to make this for mother in laws birthday today. Is it possible to use 2 8in pans and just cut the cakes in half?
totally
I’m so confused… I usually like to weigh ingredients as I am in New Zealand and often your cups are different to ours.. however you say 1 1/2 cups plus 2 TBSP of cake flour which is 186g? But if I click on metric it says 354g..
Sorry about that. I used to have a plugin on my site that automatically converted to grams and since this is an older post, i think it got messed up when I changed some things. One cup of cake flour is 115 g.
I’m confused by the recipe. If I go by the US measurements for the flour it’s a lot less than if I go by weight. I measured by weigh at first by was confused by the (186.8 g) cake flour next to where it says 2 tbsps. So I decided to use the US measurements instead, filling the measuring cups with a spoon then scraping off the top with a knife, and I used like half the flour as what the metric says.
I will look into this!
The weight measurements are wrong on this recipe. I made the filling with only 83g of freeze dried strawberries and it was way too thick. The recipe calls for 1 cup (125g) of freeze dried strawberries. I always go by weight when it’s listed. I used every bit of freeze dried strawberries that I had which was only 83g and the filling was way too thick and dry. I’m sure like 40 grams would be plenty. Pretty upsetting as freeze dried strawberries are so pricey and I ended up not having any left for the outside of the cake. I was so bummed it didn’t turn out well.🫤 The weight measurements are messed up for the cake flour too but I saw the comment which mentioned the correct measurements. Odd that the recipe hasn’t been corrected.🤔
So sorry about that! This recipe is quite old and I used to have a plugin that automatically calculated grams but I realized it was way off 🙁 I thought we got all the recipes affected updated and apparently missed this one.
This recipe needs some work. Love the concept but there were several problems I encountered. (Note: I have made several CBC recipes with great success)
Problem 1: the cake layers were very thin. Not like the pictures. It ended up ok since the filling was so thick.
Problem 2: the cakes took much longer to cook. Probably 20-25 min. That happens sometimes so I’ll let it slide.
Problem 3: the amount of freeze dried strawberries was grossly incorrect. Mostly regarding the weight. But when shopping how else are you to know? If you buy the amount by weight that is stated (250 g) you would need to buy 2 #10 cans, which would cost over $50! No thank you. In reality I used half a can of fd strawberries which was about 90 g total.
Problem 4: the shortbread crumble. I bought Scottish shortbread (less ingredients…less chemicals). I also used the weight when compared to the LD cookies she used. When I pulsed this with butter it turned into goo. I thought when I baked it it would firm up. Not really. I’m still not sure why I had to rebake a baked item? This step seems very unnecessary and a waste of butter. My advice is to just crumble up a quality shortbread cookie.
Problem 5: the frosting is THIN and runny. I should’ve added more powdered sugar but I was trying to trust the original recipe. Maybe it’s supposed to be sticky and gooey to help the topping stick but it was a gloppy mess.
Problem 6: I had more topping than I needed. This is sad because the fd strawberries are a costly item. I would half the topping if you want your cake to look like the one pictured.
Baker beware! I still haven’t tasted it (I made it for my nieces birthday) but I hope that this recipe receives more refining to reflect the quality that CBC is known for.
