Strawberry Rhubarb Olive Oil Cake Trifle

Prep Time 20 minutes
Cook Time 50 minutes
Servings 10 - 12

Ingredients

For the cake:

  • 1 ½ cups (326g) olive oil
  • 3 large eggs
  • 1 ¼ cups (302g) milk
  • Zest + juice of 1 lemon
  • 1 ¼ cups (253g) cane sugar
  • 2 cups (245g) all-purpose flour
  • 1 tsp kosher salt
  • ½ tsp baking soda
  • ½ tsp baking powder

For the fruit:

  • 3 cups chopped or quartered strawberries (from 16 oz)*
  • 3 cups sliced rhubarb (about 1 lb)*
  • 2-4 tbsp maple syrup

For the whipped cream:**

  • 16 oz heavy cream
  • Zest from 1 lemon
  • *You can substitute any amount of the strawberries or rhubarb with another summer berry. I love adding fresh or frozen raspberries into the mix for a brighter red color. To make it red white and blue for July 4th, sprinkle some fresh blueberries into the layers or on top.
  • **While I always opt for whipped cream, you could also serve topped with vanilla ice cream!
  • Note: ~ if you don’t want 10-12 servings, easily cut the recipe in half and bake the cake in an 8x8 square baking dish. The only tricky part is measuring out 1 ½ eggs!
  • Note on bake time: ~ you can’t really overbake this cake because it’s so moist, I like to bake it long enough to get a lot of that golden brown color on the top. All ovens are different so use your judgement!

Items you can prep ahead (optional)

  • Make and bake the cake. Let cool, then tear into chunks and store in the fridge.
  • Chop 3 cups strawberries 
  • Slice 3 cups rhubarb
  • Cook the fruit layer

Instructions

To prep the cake:

  • Preheat the oven to 325F. Line a 9x13-inch baking dish with parchment.
  • In a large bowl, whisk together the oil and eggs until smooth. Whisk in the milk, lemon zest + juice, and sugar until smooth. Add the flour, salt, baking soda, and baking powder and use a rubber spatula to stir and fold until just combined (try not to overmix). There will be lumps and they will disappear when you bake it!
  • Transfer to the prepared baking dish. Bake for 40-50 minutes, or until the top has dark golden brown spots all over and a toothpick comes out clean (see note). Let cool, then once it’s cool enough to handle remove it from the pan to cool completely. Break it into 2-inch chunks. Once it’s completely cool, store in an airtight container in the fridge.

To make the fruit layer:

  • Add all ingredients to a medium pot over medium heat.  Bring to a boil/rapid simmer, then reduce the heat to medium-low to maintain a simmer. The fruit will start to break down and release water, you can add a splash of water if needed in the beginning. Simmer for about 10-20 minutes, stirring occasionally, or until the rhubarb has mostly broken down and the mixture has thickened. Taste and add more maple if needed. Transfer to a bowl to cool, then to the fridge overnight to completely cool (it will thicken up as it chills).

To assemble:

  • To make the whipped cream, add the cream to a large bowl and use an electric mixer to beat until it has stiff peaks. Add the lemon zest and beat briefly to combine.
  • To assemble, in a large glass bowl or trifle bowl add a layer of the cake chunks, then dollop the fruit all over. Repeat this until the bowl is nearly full or you run out of cake/fruit. Top with a massive mound of whipped cream. Drizzle olive oil all over. Keep extra whip on the side for people to add to their servings.

Notes

Substitutions:

  • To make gluten-free, you can try substituting with a 1:1 al purpose flour.
  • This cannot be made vegan, unless you have a vegan egg substitute that works well. Replace the whipped cream with whipped coconut cream.
  • You can really use any combination of cooked fruit - stonefruit like peaches or plums would be so good!

Storage:

  • Store leftovers in an airtight container in the fridge or freezer:
    • Cake: up to 6 days in the fridge or 2 months in the freezer (the cake freezes really well if you have extra).
    • Fruit: up to 6 days in the fridge or 2 months in the freezer.
    • Whipped cream: up to 3 days in the fridge.

Leftovers + Repurposing:

  • It’s good cold or you can let it come to room temp. Top with lots of whip and olive oil.
  • Stir the whipped cream - it tends to thin out in the fridge, so it won’t be as fluffy but it will still taste amazing!
  • Leftover fruit layer can be scooped over ice cream, yogurt, or oatmeal.
