I’m off to Italy for three weeks with my hubs and my fam (hoping pasta and gelato cure post concussive syndrome) so I have my two awesome interns popping on the blog to say hello while I’m away. First up is Emily who created a mouth-watering triple berry upside down cake to share with you all just before the holiday weekend (hint, hint). Emily has been helping out BTS for the past couple months so I’m excited to introduce her to y’all. Take it away, Emily!

Hello everyone! My name is Emily, and I am a new RD and Kara’s culinary communications intern. I am so excited to be writing this guest post and to be learning from someone I consider a dietitian rock star.

I must say I was nervous when Kara asked me what recipe I would like to do for this post. I am in awe of her ability to create gorgeous recipes with seasonal flavors and ingredients that go together perfectly, simply based off of what she thinks might be good.Vegan Berry Upside Down Cake #dairyfreeMy first food love was baking, more specifically, cake. As a 13 year old, I loved how all you had to do was follow the instructions, and stuff you had in your cabinet would turn to messy slop and then to a glorious dessert. For me, the creative piece was in the decoration. I liked using fondant and colors, and creating layers and crazy shapes out of cake.

As I entered high school and then college, and schoolwork took up more and more of my time, I became more of a lazy cook and a reluctant creative. I tend to throw whatever I have on hand that I think will taste good together. I know how to make what I consider the perfect smoothie without measuring, and I frequently make pesto or hummus by just throwing good stuff in the food processor. Recipe, who’s she? For me, this creates the same kind of magic that I felt when I first started baking.Triple Berry Upside Down Cake #vegan But alas, here I am, needing to develop my own recipe. So I asked myself, what do I have on hand?

Mixed frozen berries are a staple for me. I use them in smoothies, put them on toast, or just eat them straight. I will admit that I am a finicky fruit eater; I have no interest if it doesn’t taste flavorful and fresh. Frozen fruit is always sweet and delicious because it is frozen right after it’s picked. Also, an easy source of antioxidants (can you tell I’m a dietitian?).

I also believe that extra virgin olive oil belongs on and in EVERYTHING. Using oil in a cake keeps it moist and dense, and using extra virgin gives the cake a certain depth of flavor that is hard to even describe. It also is a fantastic source of healthy fats (there’s that dietitian again).Triple Berry Berry Olive Oil Cake #vegan

Fresh mint may not be a pantry staple, but I can grab some right out in my backyard. The front door outside of my family house in New Hampshire was surrounded with mint plants for as long as I can remember, and my mother took some to plant at home. The taste and smell reminds me of my childhood and this special place, picking and eating mint leaves straight off the plant. The flavor is subtle and fresh, not toothpast-y, alongside the berries.

The other thing I love about this cake is that it is vegan, and therefore suitable for people with dairy and/or egg allergies as well. Unlike many vegan baking recipes, it doesn’t require expensive specialty ingredients and for some, even a trip to the store.Vegan Berry Upside Down Cake #dairyfree

It is single-layer and dense, perhaps even similar to a quick bread. The cake below the berries is moist and rich, balanced by the freshness and sweetness of the berries and mint. It stays moist until the next day, so you can make it ahead of time to bring to your Labor Day party.

Every time I made this cake while testing the recipe, my family made it disappear within just a couple days. I hope you enjoy it as much as we have.

Vegan Berry Upside Down Cake

1 Star2 Stars3 Stars4 Stars5 Stars (11 votes, average: 4.45 out of 5)



For the Mint Simple Syrup:

  • 510 fresh mint leaves
  • 1/3 cup water
  • 1/4 cup granulated sugar

For the Cake:

  • 1 1/2 cups flour
  • 1 cup sugar
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup water
  • 1/3 cup extra virgin olive oil
  • 1 tablespoon lemon juice
  • 1 teaspoon vanilla extract
  • 2 cups frozen mixed berries
  • Optional: powdered sugar, for dusting


For the Mint Simple Syrup:

  1. Bring mint leaves, sugar, and water to a boil in a small pot, then remove from heat and let steep 15 minutes.
  2. Strain out mint leaves.

For the Cake:

  1. Preheat oven to 350 degrees F. Spray an 8-inch round pan with cooking spray, then line with parchment paper. Spray as much as is needed to allow the parchment paper to adhere to the pan.
  2. In a large bowl, combine flour, sugar, baking soda, and salt.
  3. In a small bowl, whisk together water, olive oil, lemon juice and vanilla.
  4. Pour wet ingredients into the large bowl. Whisk or stir just into no lumps remain.
  5. Brush the parchment paper on the bottom of the pan with mint simple syrup.
  6. Add frozen berries to the pan, making sure the berries are evenly covering the bottom surface in a single layer. Brush the tops of the berries with more simple syrup.
  7. Gently pour prepared batter over the berries into the pan.
  8. Bake until a toothpick comes out clean or the center of the cake springs back when lightly touched, about 45-60 minutes.
  9. Let cake cool on a rack, about 30 minutes, then carefully flip the cake out of the pan and directly onto a serving plate.
  10. Once cake is no longer warm to the touch, dust with powdered sugar and finish with a sprig of mint leaves, if desired.

The perfect addition to your end-of-Summer gathering or companion to a cup of afternoon tea, this vegan berry upside down cake is dense, spongy, and combines fresh flavors such as olive oil and mint into a sweet symphony. #vegan

    Wow! This looks great, and it ticks most of my boxes: vegan, pantry staples, using up abundance of summer berries.
    Question though: Could I reduce the batter sugar by half? Would doing so compromise volume/structure?
    The syrup AND the sugar of the batter AND the sweetness of the berries would make for a super sweet cake, methinks.
    Thoughts? Many thanks!

    • Hi Sadie – I think you would be okay reducing the batter sugar by half – feel free to report back if you try that modification!

  2. Luke

    Has anyone tried plant-based milk instead of water? Just curious how it would alter the taste or if it’s worth it.

  3. Amie

    Can I substitute GF flour?

    • If using GF flour, I would suggest choosing a 1:1 option, which can be substituted in exactly the same ratios. Almond, oat, and others will change the consistency and ingredient ratio. King Arthur and Bob’s Red Mill both have 1:1 GF options. Hope that helps!

  4. ABV

    Hi, just wondering which type of flour is needed for this? Plain or self-raising? Thanks!


    The cake is very moist. The amount of batter that it turned out to be enough for 2 8 inch round pans – which was fine with us. Everyone enjoyed the cake. I used fresh blueberries since it was the middle of Jersey Fresh blueberries – fresh from the farm. I made the cake for my sons 21st birthday – and we had extended family.

  6. Louise

    Hello! I can’t wait to make this 🙂 For the olive oil, do you think it will work using melted refined coconut oil or applesauce? Thank you!

    • Hi Louise! I think coconut oil should work – feel free to report back once you try it! Hope you enjoy!

  7. Molly

    Do you have to out mint in the simple syrup? Can you just make plain simple syrup?

    • You can just do plain simple syrup if you’d like! The mint just adds a bright flavor that pairs with the fruit nicely.

  8. Diana

    This is so good. was a hit!

  9. Avigail

    I have made this cake three times and it is delicious. I have played with the flavors, for example adding basil leaf to the mint simple syrup, almond extract instead of vanilla.. etc. bevy easy and quick to make with reliable results. Delicious!

  10. Christine

    Do you think I could omit the mint simple syrup? Or is it necessary for sweetness?

    • Hi! You probably could but then it won’t have that upside down cake glaze :). I’d recommend keeping it!

  11. Maggy Berry

    This cake was amazing..I was sceptical about the water in the recipe..but it tasted delicious and was very moist..
