Instructions

Raspberry Cake Filling

Make the raspberry filling first, so it has time to cool and thicken.
Place 4 cups frozen or fresh raspberries, 1 cup granulated sugar, 1 Tbsp lemon juice, 2 tsp lemon zest, and 1/4 cup of water in a saucepan and heat over medium-high heat.
Stir the mixture until it begins to boil. Lower the heat to medium-low, and allow the filling to simmer for 10-15 minutes.
Turn off heat and remove the pot from the stove. Pour the filling into a metal strainer suspended over a medium sized bowl, and push through using a rubber spatula. Use a decent amount of pressure to really get all the liquid through the sieve. You should be left with about 1/2 cup of seedy pulp.
In a separate small bowl, make a slurry by combining the remaining 3 Tbsp of water with 3 Tbsp cornstarch. Stir until the cornstarch has fully dissolved into the water.
Add this cornstarch mixture into the strained raspberry filling, and stir until it is incorporated.
Rinse out your pot and pour the filling back into it (you don't want any residual seeds getting into the filling).
Heat at a medium heat for a few more minutes, or until the mixture has thickened. Be sure to stir constantly during this stage to prevent the filling from burning.
Turn off the heat and pour the raspberry filling into a separate bowl to cool. Cover with plastic wrap and place in the fridge for at least 1 hour, or preferably overnight.

Pistachio Cake Layers

Preheat the oven to 350°F / 175°C. Grease then line three 8-inch cake pans with nonstick spray and parchment paper rounds. Set aside.
Pour 1 1/4 cups (160g) of finely chopped pistachios, 2 cups all-purpose flour, 3 cups granulated sugar, 2 1/2 tsp baking powder, and 1 tsp fine salt into a large bowl or the bowl of a stand mixer. Whisk together until combined.
Then mix 3/4 cup (1 1/2 sticks) of room temperature, unsalted butter slowly into the dry ingredients on a low speed. Continue to mix until no large chunks of butter remain and the mixture looks like moist sand.
Pour in 1 cup of egg whites and mix on low until just incorporated. The batter will be thick.
Next, mix in 1 1/2 cups of sour cream, 2 Tbsp of vegetable oil, 2 tsp of vanilla extract, and 1 tsp almond extract (optional) at a low speed until fully incorporated. If you want to amp up the color of the cake layers, add in 1/4 tsp of green gel food coloring.
Scrape down the sides of the bowl with a rubber spatula, then beat on a medium speed for about a minute to make sure everything is properly mixed together. This also helps lighten the texture of the cake layers a bit.
Divide the batter evenly between the prepared pans. I like to use a scale to make sure each pan has the same amount of batter and will bake up to the same height (about 600g per pan).
Bake for 33-36 minutes or until a toothpick inserted in the center of one of the layers comes out with a few moist crumbs. Let the pans cool for 10 minutes, then run a small offset spatula around the perimeter of the pan to separate the cake from the pan.
Place the cake layers into the freezer for 30 minutes to accelerate the cooling process. Once the layers are fully cooled, carefully flip the pans and remove the layers.
Use a serrated knife to level the tops of the layers right before you plan to assemble your cake, or you can wrap and freeze the layers if you're making them in advance.
If you make these cake layers in advance and freeze them, let them thaw for about 20 minutes before making your cake. The cake layers should still be slightly cold to the touch, which will make it easier to assemble the cake.

Raspberry Swiss Meringue Buttercream

While the cake layers bake and cool, make the raspberry buttercream frosting. Before making this frosting, be sure to thoroughly clean your mixing bowl. If there’s any grease, it can make it difficult to whip up the meringue.
In a medium-sized pot, add about 1 inch of water and bring to a simmer. Add 8 egg whites and 2 1/2 cups of granulated sugar into a large metal bowl.
Place the bowl on top of the pot filled with simmering water. The bowl should create a seal over the pot. Make sure the water isn’t actually touching the bottom of the bowl, or it can cook the egg whites.
Whisk the mixture constantly for about 3 minutes, until it reaches 160°F/71°C. You can test the mixture to see if it’s ready by rubbing a tiny bit between your fingertips. The sugar should be fully dissolved, and it should feel super smooth and hot to the touch.
Once it reaches this stage, lift the bowl away from the pot and dry the bottom with a towel. Pour the mixture into the bowl of a stand mixer and beat on a medium-high speed with a whisk attachment. Mix for about 10 minutes, or until you have stiff, glossy peaks that stick straight up. While the meringue whips, I like to add something cold around the base of my bowl. I find the meringue stays quite warm while it whips up, and placing a bag of frozen veggies around the base of the bowl helps cool it back to room temperature. This can prevent your buttercream from becoming soupy in the next step.
Mix in 2 cups (4 sticks) of unsalted butter at a medium speed, 1 stick at a time. Scrape the sides and bottom of the bowl with a rubber spatula as needed. If it looks soupy or broken, keep mixing until it looks fluffy and thick. If it doesn't seem to come together after an additional 5 minutes of mixing, check out the troubleshooting section in this post. I almost always have to chill my bowl in the fridge for 20 minutes before it whips up properly. The frosting should have a thick, whipped consistency once it's properly mixed.
Once the consistency is right, swap out the whisk attachment for a paddle attachment and add 3/4 cup of the fully cooled raspberry filling made above, 2 tsp vanilla extract, and 1/2 tsp fine salt. Continue mixing on a low speed for a couple of minutes to make the frosting extra smooth. Place about 1 cup of buttercream in a large piping bag, and seal the top with a clip or rubber band. Cut a 1/2-inch opening at the base of the bag. Set aside.
If you make this in advance, it can sit at room temperature for up to 2 days or be stored in the fridge for up to 2 weeks.

Assembling This Pistachio Raspberry Layer Cake

Stack and frost the cake layers on a greaseproof cakeboard or flat plate using a dab of frosting to help stick the first cake layer to the board.
Spread about 1 cup of raspberry buttercream onto the first cake layer with a large offset spatula. Pipe a buttercream ring around the edge of the cake layer, then fill the center of it with half of the remaining raspberry filling. Repeat with the next cake layer, and place the third cake layer on top.
Chill the cake in the fridge (30 minutes) or freezer (10 minutes) until the frosting is firm to the touch.
Then spread the remaining raspberry buttercream around the cake and create a textured look using an offset spatula or the back of a spoon. Add a semicircle of fresh raspberries and chopped pistachios around the top of the cake, then enjoy.

Notes

If you want to use whole eggs to make the cake batter instead of egg whites, you can use 4 large, room-temperature eggs.

If you need to use salted pistachios, omit the salt from the cake batter recipe.

Recipe Variations - Making This Cake in Different Sizes

One batch of this recipe makes about 10 cups of batter or about 1800 grams. If you plan to use three circular cake pans, add about 600 grams of batter into each pan.

If you want to make a tiered cake or a different-sized cake with this recipe, check out my cake batter calculator to see how many batches of batter you'll need.

This recipe can also be used to make a sheet cake! One batch will make a 1, 9 x 13-inch cake layer that's about 1.5 inches tall once leveled.

Bake for 45-55 minutes at 350°F / 175 °C, or until a toothpick inserted in the center comes out with a few moist crumbs. Bake time can vary a lot based on the type of pan you use, if you use heating cores, and your oven. I recommend using heating cores if you have them; they help sheet cake layers bake more evenly and quickly.

For more details on how to convert this cake recipe and others into sheet cakes, check out my sheet cake guide.

Last but not least, you can also make cupcakes using this recipe. Fill the liners 3/4 full and bake them at 350°F / 175 °C for 19-21 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. You should end up with about 3 dozen.

Tips for Making the Best Raspberry Pistachio Cake

Ingredients at room temperature mix together better! Set out any cold ingredients ahead of time.
Properly measure the flour (spoon it into the cup measure, then level). Or better yet, use a kitchen scale to measure your dry ingredients.
Use a scale to weigh your cake pans as you fill them. It will make your cake layers bake to the same height and bake more evenly.
Make sure the buttercream is the right consistency. This will help give the cake proper structure and make it easier to decorate.
Level the room temperature or thawed cake layers with a serrated knife to make them easier to stack.
Chill your cake layers in the freezer for about 20 minutes before assembling the cake. It makes it so much easier to stack and frost them!
If your cake layers turn out less than perfect, read my cake troubleshooting guide to see where things might've gone awry.

Making This Cake in Advance & Storage Tips

I highly recommend making the cake layers in advance and freezing them. It breaks the process up and makes it more approachable and enjoyable, and I promise they taste just as delicious!

You can also make the frosting ahead of time or save any leftover frosting! It can be stored in an airtight container in the fridge for up to a month or in the freezer for up to 3 months. Be sure to give it a good stir once it thaws to get the consistency nice and smooth again.

A frosted cake can last in the fridge for up to a week (as long as it doesn't have a perishable fruit filling) or in the freezer for up to a month. The buttercream locks in all the moisture, keeping the cake fresh and delicious!

If you cut into the cake and have leftovers, use any remaining frosting to cover the cut section to keep it moist and store it in the fridge for up to a week.
