Strawberry cake with lime buttercream

Jump to Recipe

I love the strawberry lemon combo, a lot. But, I love strawberry lime even more. This strawberry cake with lime buttercream is my dream cake. Y’all, it is just so good. It is light, fluffy and has great flavor.

Fresh matters!

This cake uses fresh berries and limes, you really shouldn’t skimp on this. I have seen other recipes using preserves or even the bottled lime juice, but it’s not worth it. Fresh is better in this case!

Roasted strawberries

SO, start with the berries. We are just going to roast with a little sugar and puree. It is an extra step, but worth it. Roasting intensifies those flavors and is so yummy!

Start by removing tops and cutting in half.

Next, sprinkle with a little sugar. I didn’t use hardly any as my berries were already pretty sweet. I just mixed right on my cutting board, but you can also do this on the pan and save yourself any extra dishes.

These took about 20 minutes on 350 degrees. The time will depend on your strawberries and actual temp of your oven. You will know when they are done, as they will be soft and the juices will have released.

Once they are done, throw them in the blender or food processor and pulse until they are relatively smooth.

Flour

I used 2 flours in this recipe, cake flour and a whole wheat pastry flour. In order to keep baked goods, like cake, light and fluffy when using a wheat flour, you need to make sure it is a soft wheat. I have loved Farm Fresh Wheat, it’s the only soft wheat I have been using for at least 8 months or so. I love it! The berries are ground in my Nutrimill of course.

Making the cake batter

This is a white cake variation, so I used only egg whites, it helps keep that solid white color you are looking for.

The fat in the recipe comes from butter and oil. It seems a little extra to use both, let me explain. I can’t resist the flavor of butter (who can??), but I love the soft texture oil give as well. So, both it is!

Granulated sugar is used for the sweetener. You can also use coconut sugar if you prefer. I don’t like the flavor as well, but that is a personal preference. You can use brown sugar too, but that will affect the flavor and color.

Mix the butter, oil and sugar first. Then add in your egg whites.

Softasilk is a great brand for cake flour and always readily accessible. Mix those dry ingredients in a separate bowl.

Combine wet and dry, and fold until combined. Now, you can add red food coloring if you want a brighter red cake than the natural berries would give. I like the natural color, so I didn’t add any.

Here is the finished baked cake.

Lime buttercream

While it is cooling, start your buttercream. I love to have a good lime flavor, so the zest is where it is at. This microplane has been my go to for a long time. I definitely recommend it!

This is an American buttercream, so butter, powdered sugar, vanilla and a little liquid will do!

I normally use milk in the recipe, but this time I used lime juice to amp up the lime flavor!

Spread generously over the top of the cooled cake. I use this small offset spatula for almost all my icing. I just like the size!

Swirl and spread this icing however you feel inclined.

Sprinkle with a little more lime zest and it is ready to go!

Equipment

  • 9×13 pan, hand mixer

Ingredients

Strawberry cake

  • 2 cups fresh strawberries, tops removed and cut in half
  • 1 tablespoon granulated sugar this is for roasting the strawberries
  • 1 3/4 cup cake flour It's important to use a low protein flour, like cake flour for a tender cake.
  • 1 cup whole wheat pastry flour
  • 2 1/2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1/2 cup butter, softened
  • 1/2 cup canola oil or other neutral oil
  • 1 1/4 cup granulated sugar You can reduce this to 1 cup if you prefer
  • 3/4 cup milk I used a nonfat vanilla almond milk.
  • 5 egg whites
  • 2 teaspoons red food coloring optional if you want a brighter color. I did not use this, as I like the natural color, but the option is there.

Lime buttercream

  • 10 tablespoons butter, softened
  • t tablespoons lime zest, divided I use about 3 tablespoons in the icing, then the last tablespoon sprinkled on top.
  • 4 cups powdered sugar
  • 1/2 teaspoon vanilla
  • lime juice The amount of this will depend on how thick or thin you want your icing to be.

Instructions

Strawberry cake

  • Preheat oven to 350 degrees.
    Line a baking sheet with parchment paper and set aside.
    Combine the strawberries and 1 tablespoon. Mix to distribute the sugar. Pour onto baking sheet.
    Bake for about 10-25 minutes. This will depend on how thick your berries are and how ripe. You will know when they are done, the strawberries will be soft and will have released plenty of liquid.
    Remove from oven. Place the roasted berries in food processor or blender. Pour onto a plate. I like to pour this out, as this will give you more surface area and it will cool more quickly.
    Now, let's start on our cake. Leave your oven on 350 degrees.
    Prepare your 9×13 pan. I lined mine with parchment paper with an overhang. This is optional, but it makes it so much easier to remove the cake from the pan once it is done baking.
    Mix your flours, baking powder and salt in a small bowl and set aside,
    Mix the butter, oil and 1 1/4 cup granulated sugar in a medium bowl. I used a hand mixer, but this can be done by hand as well.
    Once these are well blended, and in your eggs. Mix to combine.
    Next is your strawberries and vanilla.
    Now, alternate your milk and dry ingredients. Do this by adding in 1/2 you milk and mix lightly. Next, add in half your dry ingredients. Repeat the process until everything is incorporated.
    Pour batter into your prepared pan and place in the oven.
    Bake for 20-30 minutes. The variation in time is dependent upon your actual baking temp and pan.
    Check on doneness with a toothpick. When it is inserted, it should come out almost totally clean.
    Remove from oven and allow to cool at least 10-20 minutes before removing. If you have used parchment, the removal is simple. Place on cooling rack. If not, invert and flip again. Top side up on cooling rack.
    Once it has cooled, you are ready for icing!

Lime buttercream icing

  • Combine butter, powdered sugar, 3 tablespoons lime zest, vanilla and at least 2 tablespoons lime juice. Mix well with hand mixer on high. Now, from here you will determine how thick or thin you want your icing to be. I wound up using about 1/4 cup lime juice in mine. If you want more or less, do this.
    Spread evenly across cake. Sprinkle with the remaining tablespoon lime zest.

    1 3/4 cup cake flour It’s important to use a low protein

    –> Type 00 flour has about 9% protein. Does that work here?

    Thanks!

      yes! Should work. Cake flour is usually about 8%. Sorry for the delay in responding, we were camping and out of service for the weekend.
