today my baby girl, my first, turns 6. SIX! how does it feel like the blink of an eye and eternity at the same time? this birthday is such a strange one. this birthday just happened to come in the middle of a pandemic. no friends or family will be at this birthday party. there will be homemade decorations, zoom calls and cake. oh there will be so. much. cake. this sumac roasted strawberry layer cake. created just for her. and you.
this cake is made from her favorite fruit and my penchant for tweaking classics into something modern. her two requests: make it pink and have lots of strawberries! to make cake and buttercream frosting you'll need :
- all purpose flour
- cake flour
- sugar
- eggs
- butter
- oil
- baking powder
- salt
- vanilla extract
- powdered sugar
- ground sumac
- 2 glorious pounds of strawberries
how to roast strawberries
roasting strawberries is an easy and simple way to add lots of flavor. by roasting the strawberries, the sugars caramelize. this adds a depth of flavor you can't get with fresh. it also tames the natural tartness of the berries. adding sumac brings an earthy, punchy tartness back to the strawberries. now you have the best of all the flavor worlds.
to roast strawberries you need a baking pan and parchment paper.
- wash, hull and halve berries (or quarter if large)
- place berries on the parchment lined baking sheet
- sprinkle sugar, lemon juice, vanilla extract and ground sumac
- throughly coat berries in the sugar mix
- roast at 375F for about 30 minutes
- transfer to a glass measuring cup (for ease)
- cool to room temperature
what is sumac?
sumac is a spice typically utilized in middle eastern cooking. its rarely found in desserts. this ruby hued spice packs a tart, citrusy punch. one that's unique to this spice. sumac is derived from the sumac flower. the berries are dried and ground. most often, this spice is used in savory dishes. it is a common ingredient in za'atar and is used to dust everything from pita bread, to lamb, to desserts.
the most common flavor counterpart would be lemon zest. although, sumac is less pungent than lemon juice, it lends a similar punch of citrusy flavor. along those lines, sumac pairs well with:
- fresh fruits and veggies
- as a rub for meats (think lamb, chicken and fish)
- topping for dips such as hummus
- desserts featuring berries, lemon or chocolate

tips for making a layer cake
making a layer cake can be intimidating at first. in reality, it's a lot of fun. the reward is a cake that can't help but impress. to make this easier, here are a few tips:
- weigh the batter on a food scale. this ensures each cake pan has the same amount of batter
- fill 6-8" pans 2/3 way full. 9" + only 1/2 way full
- if possible, use the same type of pan (metal, color, brand). this helps make sure each layer bakes at the same time and the same doneness
- use cake strips. these are a recent revelation of mine. they help regulate the temperature of the batter in the pan, ensuring an even bake and no caving
- cool cakes in the pan for 10-15 minutes. remove and cool on the cooling rack until room temperature
- chill for minimum 2-3 hours before frosting
- place a dollop of frosting on the cake stand/plate
- spread an even layer (about 3/4 c per layer) across to slightly over the edge
- place next layer on top
- smooth 1 1/2 c on the top
- use the remaining frosting to coat the exposed edges
- chill another hour before frosting again (if doing more than the crumb coat)
final tips for the perfect sumac roasted strawberry layer cake
- all cold ingredients should be room temperature
- preheat the oven for at least 20-25 minutes before baking
- line cake pans with parchment along the bottom
- cool roasted strawberries to room temperature before using in the batter
- use the zest of two lemons in place of sumac (if you don't have any)
- mash strawberries well. the smaller the pieces, the better it mixes
- cakes edges will pull slightly away from the pan and tops will be golden. hopefully this happens at the same time. if not, remove the one that is done and bake the other longer. check for doneness every 1-2 minutes after
- cool cakes to room temperature
- chill layers in the fridge or freezer before frosting
- wrap layers in plastic wrap if chilling for longer than a few hours
- chill frosting cake after applying the crumb layer if frosting again
- 4 cups frosting is perfect for a 8-9" two layer cake. 5 cups for a 8-9" three layer cake

This recipe was so fun to make and very very delicious. The cake was both moist and fluffy which is not always an easy task to accomplish.
Roasting the strawberries made the house smell incredible. I think I will be roasting more to use on ice cream or pancakes ????.
Also if anyone is interested I did substitute the yogurt with buttermilk and it worked beautifully.
Thank you for this lovely and easy to follow recipe.
Hi Rebecca! Im glad to read this cake worked for you! I think the buttermilk sub was an excellent choice. 🙂 Thank you for trying the recipe and leaving a review!
Thanks for posting this recipe. The sumac adds such a delicate layer of flavor that elevates this above other strawberry cakes I’ve had. The cakes came out so moist, but not too dense. The only substitution I made to the recipe was using rose water in the frosting instead of vanilla extract. The subtle floral tones worked quite well with the sumac/berry combo already in place.
Hi Elle! Thank you so much for trying the recipe. I am happy to see you enjoyed it! 🙂
Hey there!
So excited to try making this.
Just wondering with subbing the whole Greek yogurt to milk. Do you mean regular whole milk at the same quantity.?
Hi Jessica! I would sub with 1:1 buttermilk (or regular milk with 2 tsp lemon juice added about 10 minutes before using. This curdles the regular milk to mimic buttermilk)
I made this cake for my sisters 30th birthday and it was AMAZING! The roasted strawberries added such a beautiful color and flavor. Definitely will be making this again!
This cake was such a hit with our household. We tend to favor fruit flavored desserts and this was so moist and delicious!
Thank you so much for making this cake! I am so happy your family loved it!
Hi! I want to know what are the little red pieces on top... looks like something crunchy... Thanks!
Hi Estefi,
Those red flakes are crushed up freeze dried strawberries. Its more a decorative touch than anything else. Think of them as sprinkles!
Hi! This looks incredible. Is all purpose flour ok here? I have a hard time finding cake flour but I don’t want it to get too dense..
Hi Julia, no problem. You can make a DIY cake flour: 2 cups all purpose flour (240-250g). Remove 4 tbsp or 1/4 c (30g). Replace the flour that was removed with 1/4 c cornstarch. Sift the new mixture together 4-5 times. This makes an approximate 2 cups cake flour.
