Why you’ll love this recipe?

Who doesn’t like an easy and delicious recipe? I know, I do. I tested this recipe many times until I was happy with it. Once, I made it with honey instead of sugar, but it turned out dense, and somehow the texture was not right. I also tried it with regular yogurt, not the thick, full-fat type. Again, the texture was off, and I wasn’t happy with it. I made it a few more times, tweaking ingredients until I was finally satisfied with the result.

It has the perfect texture, balanced sweetness, just the right amount of orange flavor, and poppy seeds. The olive oil pairs very well with the orange and the nuttiness from the poppy seeds. I also added the option of soaking/brushing the cake with orange syrup, which adds to the orange flavor and the texture. Instead of brushing the cake, you can use the syrup to drizzle over a slice. Of course, you can simply not use syrup and enjoy the cake as is.

Another thing I love about this orange poppy seeds olive oil cake is that it stays fresh and moist for days if covered well. I use a plastic bag, or for it to look prettier, I place it under a glass dome cake stand.

Recipe Ingredients

Ingredients for orange poppy seeds olive oil cake.

Full-fat yogurt or sour cream. I recommend using a thick type of yogurt (e.g., Greek) or sour cream. This will make the cake moist with a beautiful texture.

Olive oil. Any good-quality olive oil will work. It adds a hint of fruity, grassy flavor typical of olive oil. Depending on the brand of olive oil used, the flavor will vary slightly.

Poppy seeds. I love poppy seeds! I think they are not given enough credit and are left in the shadows. They add a pleasant nuttiness and texture, and let’s be honest, they look pretty paired with the orange.

Note! For exact measurements and detailed directions, see the recipe card below.

Step 1: Rub the orange zest and the sugar to release the oil and yummy citrus aroma.

Step 3: In another bowl, whisk the dry ingredients. Add them to the wet and mix until combined.

Step 4: Line a baking tray with parchment paper, pour the batter, and bake until a toothpick comes out clean.

Recipe Tips

Let the poppy seeds soak. Letting them sit in the liquid for at least 10 minutes makes them softer and lets them release more flavor when cooked.

Combining zest and sugar. Rubbing the zest into the sugar helps release the oils and enhance the citrus flavor.

Additions and substitutions

  • You can use sour cream if you don’t have thick, full-fat yogurt.
  • I don’t recommend substituting olive oil for other vegetable oils due to its distinct flavor, but you can definitely do it.
  • Instead of the orange syrup, you can make a glaze by combining powdered sugar with orange juice, making it as thick or runny as you like and pouring/brushing it over the top of the cake.
  • Another option as a topping is to make a cream cheese, mascarpone, or buttercream frosting.
  • You can also serve a slice of the cake with a dollop of yogurt, sour cream, or crème fraîche.

Storage and reheating

This orange poppy seeds olive oil cake can be kept covered at room temperature for up to 4 days. You can freeze the cake after it has completely cooled, slice it, and place a piece of parchment paper between each slice so they don’t freeze to each other. Place in a freezer-safe bag and freeze for up to 3 months.

To reheat the cake, take as many slices as you want and let them defrost at room temperature or place them in the oven at 350F (180C) for a few minutes until soft.

Recipe FAQ

Yes, you certainly can. I think a 6-8 inch round cake form will be enough to make 2-3 layers. If you want a bigger size, you might need to double the ingredients.

Yes, you can use butter instead of the olive oil, although the cake will miss the specific flavor that olive oil has.
