This Orange and Poppy Seed Cake joins a family of citrus cakes such as Orange Chiffon Cake and Orange Pound Cake. Poppy seeds are a classic inclusion in many traditional Jewish and Israeli bakes, contributing subtle flavor and texture. Using oil instead of butter keeps the crumb exceptionally moist and makes this an easy, reliable cake to bake without advanced planning.

Topping Options and Serving Suggestions

A simple dusting of powdered sugar is lovely alongside a cup of tea, but you can dress this cake up in several ways depending on your taste:

• Brown butter cream cheese frosting — rich, tangy and luxurious; add orange zest for extra citrus depth.
• Chocolate ganache — milk, dark, or white for a more decadent finish.
• Mascarpone frosting — creamy and lightly tangy, it complements the orange flavor well.
• Simple orange glaze — mix 2–4 tablespoons of fresh orange juice with 1 cup of powdered sugar for a glossy, bright topping.

Ingredients

You’ll need the following ingredients to make this cake. Quantities and full measurements are included in the recipe card below.

• Whole poppy seeds — use whole seeds for texture and the best flavor; toasting them briefly intensifies their aroma.
• Eggs, separated — room temperature yolks and whites, with absolutely no yolk in the whites for proper meringue.
• Fresh oranges — zest and juice from two oranges deliver bright, fresh citrus flavor.
• Vegetable oil — canola or any neutral oil keeps the cake moist; olive oil can be used for a more savory, earthy note.
• Granulated sugar — this recipe uses a bit more sugar to balance poppy seed bitterness; you may reduce up to 1/4 cup if you prefer.
• Cake flour — important for a light crumb; if you don’t have it, mix bleached all-purpose flour with 2 teaspoons cornstarch and process briefly.
• Baking powder, vanilla extract, and a pinch of salt.

Step-by-Step Instructions

A concise overview of the method is below; follow the recipe card for exact measurements and baking times.

1. Toast the poppy seeds on a baking sheet in a 350°F oven for about 10 minutes, stirring halfway through. Remove and cool.
2. Preheat the oven to 320°F and line a 9×13-inch pan with parchment paper; do not grease the sides so the cake can cling and rise.
3. In a large bowl, whisk together the egg yolks, oil, orange juice, orange zest, vanilla, and most of the sugar until smooth.
4. In a separate bowl, stir together the cake flour, baking powder, salt, and toasted poppy seeds.
5. Gently fold the dry mixture into the yolk mixture until just combined. Do not overmix.
6. Whip the chilled egg whites until frothy, then with the mixer on high gradually add the remaining sugar and whip until a glossy, white meringue forms. The meringue should be shiny but still slightly soft and not hold firm peaks.
7. Carefully fold the meringue into the batter using a rubber spatula: scrape from the bottom and lift the mixture over itself until the meringue is fully incorporated. This keeps the cake light and tall.
8. Pour the batter into the prepared pan and bake until a toothpick inserted into the center comes out clean. Baking time varies with pan choice—refer to the recipe card below.
9. Cool the cake in the pan. When cool, run a knife around the edges to release and slice to serve.

Tips and Substitutions

• Always zest oranges before you juice them to capture the most aromatic zest.
• To make a lemon version, substitute the oranges with 4–5 lemons or with blood oranges for a different flavor profile.
• If you prefer no citrus, replace the orange juice with whole milk or sour cream for tenderness and moisture.
• Avoid overmixing the batter once the dry ingredients are added to prevent a dense cake.
• Folding the meringue gently is essential: fold until no streaks remain to preserve volume.
• Make sure egg whites are free of any fat or yolk; separate eggs while cold and bring to room temperature before whipping.

Storing, Yield, and Pan Options

• Storage: Keep the cake covered at room temperature for up to 3 days. For longer storage refrigerate for up to one week or freeze for up to three months. Wrap tightly in plastic and a freezer bag when freezing; thaw at room temperature.
• Yields and pans: This recipe is flexible. Use one 9×13-inch pan for about 24 slices, one tube pan for about 12–15 slices (baking time increases), or two 8-inch round pans to make layers (baking time decreases). Adjust baking time as noted in the recipe card.

Orange and Poppy Seed Cake Recipe

Tall, tender, and moist orange and poppy seed cake with a bright citrus flavor and light texture.

Ingredients

• 1 cup whole poppy seeds (about 140 g)
• 6 large egg whites
• 6 large egg yolks
• 1/2 cup canola oil (120 ml)
• 1/2 cup fresh squeezed orange juice (120 ml)
• Zest of two oranges
• 1 teaspoon vanilla extract
• 1 3/4 cups sugar, divided (about 350 g)
• 1 2/3 cups cake flour (about 200 g)
• 1 1/2 teaspoons baking powder
• 1/4 teaspoon salt

Instructions

1. Spread the poppy seeds on a baking sheet lined with parchment and toast in a 350°F oven for 10 minutes, stirring at the 5-minute mark. Remove and cool.
2. Preheat the oven to 320°F. Line a 9×13-inch pan with parchment paper; do not grease the sides.
3. In a large bowl, combine egg yolks, oil, orange juice, orange zest, vanilla, and 1 1/4 cups (250 g) of the sugar. Whisk until smooth.
4. In a separate bowl, whisk together cake flour, baking powder, salt, and the toasted poppy seeds.
5. Gradually add the dry ingredients to the yolk mixture, stirring just until combined.
6. Using an electric mixer, whip the egg whites until frothy (about one minute). With the mixer on high, gradually add the remaining 1/2 cup (100 g) sugar and whip until a glossy, medium meringue forms. The meringue will not hold stiff peaks.
7. Fold the meringue into the batter gently until no streaks remain. Pour the batter into the prepared pan.
8. Bake for 35–38 minutes, or until a toothpick inserted in the center comes out clean. If using a tube pan, bake 38–42 minutes; two 8-inch pans will need about 15–18 minutes.
9. Remove from the oven and allow the cake to cool in the pan. When cool, run a sharp knife around the sides, remove, slice, and serve.

Notes

• Store covered at room temperature for 3–5 days. Freeze wrapped for up to three months.
• Egg whites must be free of yolk or fat to whip properly. Separate eggs when cold and bring whites to room temperature before whipping if needed.
• When folding, be gentle to preserve the air in the meringue; overmixing will deflate the batter and yield a denser cake.
• Citrus substitutions: swap oranges for lemons, blood oranges, or replace the juice with milk or sour cream for a non-citrus version.
