What Ingredients You Will Need

This Moist Orange Chocolate Sheet Cake recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. Most of these items are pantry staples, and if you’re missing something, I’ve got substitutions below to keep you covered.

• For the Cake Batter:
• All-purpose flour – 2 cups (240 g), for structure and tenderness
• Granulated sugar – 1 ¾ cups (350 g), balances the citrus and chocolate
• Unsweetened cocoa powder – ¾ cup (75 g), I recommend Ghirardelli for best richness
• Baking powder – 1 ½ teaspoons, to give the cake lift
• Baking soda – ½ teaspoon, helps lighten the texture
• Salt – ½ teaspoon, enhances all the flavors
• Large eggs – 2, room temperature for better mixing
• Buttermilk – 1 cup (240 ml), adds moistness and tang (can substitute with milk + 1 tbsp vinegar)
• Fresh orange juice – ¾ cup (180 ml), freshly squeezed for the best zing
• Vegetable oil – ½ cup (120 ml), for that soft crumb
• Vanilla extract – 2 teaspoons, to round out the flavors
• For the Creamy Orange Frosting:
• Unsalted butter – ½ cup (115 g), softened (I prefer Kerrygold for creaminess)
• Cream cheese – 8 oz (225 g), softened, for tang and richness
• Powdered sugar – 3 cups (360 g), sifted for smooth frosting
• Fresh orange zest – 2 teaspoons, packed with citrus aroma
• Fresh orange juice – 2 tablespoons, adds brightness
• Vanilla extract – 1 teaspoon, subtle depth

Substitution tips: Use almond flour for a gluten-free twist (though texture will be denser). Swap dairy butter and cream cheese with plant-based alternatives to keep it vegan-friendly. In summer, try swapping fresh orange zest for blood orange zest for a colorful, seasonal flair.

Equipment Needed

• 9×13 inch (23×33 cm) sheet pan – the perfect size for this cake’s ideal thickness
• Mixing bowls – medium and large
• Electric mixer or stand mixer – makes whipping the frosting a breeze
• Whisk and spatula – for combining ingredients gently but thoroughly
• Measuring cups and spoons – accuracy is key for baking success
• Microplane zester – for extracting fresh orange zest with minimal effort (a box grater works in a pinch)

If you don’t have an electric mixer, you can absolutely mix by hand, but expect a bit of an arm workout. I’ve used both and honestly, the mixer saves you time and gives a smoother frosting every single time. For budget-friendly options, a hand whisk and sturdy mixing bowls do the trick just fine.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease your 9×13 inch (23×33 cm) sheet pan and line it with parchment paper for easy removal later. This step ensures your cake won’t stick and keeps the edges neat.
2. Mix dry ingredients. In a large bowl, sift together 2 cups (240 g) all-purpose flour, ¾ cup (75 g) cocoa powder, 1 ½ tsp baking powder, ½ tsp baking soda, and ½ tsp salt. Whisk to combine evenly.
3. Combine sugar and wet ingredients. In a separate bowl, whisk 1 ¾ cups (350 g) granulated sugar with 2 large eggs until light and fluffy (about 2 minutes). Add ½ cup (120 ml) vegetable oil, 1 cup (240 ml) buttermilk, ¾ cup (180 ml) fresh orange juice, and 2 tsp vanilla extract. Mix until smooth. The orange juice here is what keeps the cake moist and adds that zing.
4. Slowly add dry ingredients to the wet mixture, folding gently with a spatula until just combined. Don’t overmix or you’ll risk a tougher crumb. The batter should be smooth but a little thick—like brownie batter.
5. Pour batter evenly into the prepared sheet pan. Smooth the top with a spatula. It should fill the pan about halfway, which is perfect for even baking.
6. Bake for 30-35 minutes or until a toothpick inserted in the center comes out with just a few moist crumbs. Oven temps vary, so start checking at 30 minutes. The cake should spring back lightly when you press the top.
7. Cool the cake completely in the pan on a wire rack. This usually takes about 1 hour. Patience here is key—frosting a warm cake leads to melty frosting and a mess.
8. Prepare the frosting. In a large bowl, beat ½ cup (115 g) softened unsalted butter and 8 oz (225 g) softened cream cheese until creamy and smooth (about 3 minutes with a mixer). Gradually add 3 cups (360 g) powdered sugar, beating well after each addition.
9. Add zest, juice, and vanilla. Mix in 2 tsp fresh orange zest, 2 tbsp fresh orange juice, and 1 tsp vanilla extract. The frosting should be thick but spreadable. If it’s too runny, add a bit more powdered sugar; too stiff, add a splash more juice.
10. Spread the frosting evenly over the cooled cake using an offset spatula or butter knife. For a neat finish, chill the cake for 15 minutes before slicing.

Pro tip: If you want extra orange flavor, sprinkle a tiny pinch of coarse sea salt over the frosted cake before serving. It balances the sweetness and makes your taste buds dance.

Cooking Tips & Techniques

Here’s what I’ve learned from countless batches of this Moist Orange Chocolate Sheet Cake:

• Don’t skip fresh orange juice and zest. Powdered orange flavor just won’t cut it here. Freshness makes all the difference.
• Room temperature ingredients are your friend. Cold eggs or butter can lead to lumpy batter and frosting—take your time letting them warm up.
• Use buttermilk or a buttermilk substitute. It reacts with baking soda to make the cake light and tender, plus it adds a subtle tang that complements the orange.
• Watch your oven temperature. If your cake looks done on top but is still wet inside, your oven might run hot. Try lowering the temperature by 10-15°F (5-8°C) next time.
• Don’t overmix the batter. Fold just until combined to keep the crumb soft and moist.
• Frost only when completely cooled. I’ve learned this the hard way after a few messy frosting meltdowns!

Timing is key too—prep your frosting while the cake cools to save time. Also, multitasking by zesting the oranges while the cake bakes keeps things moving smoothly in the kitchen.

Variations & Adaptations

This recipe is super flexible—here are some ways I’ve tweaked it depending on mood and occasion:

• Gluten-Free Option: Swap all-purpose flour for a 1:1 gluten-free baking blend. The texture is a bit denser but still delicious.
• Dairy-Free Version: Use coconut yogurt instead of buttermilk and vegan butter plus dairy-free cream cheese for the frosting. The coconut adds a nice tropical note.
• Spiced Orange Chocolate: Add 1 teaspoon ground cinnamon and a pinch of cayenne pepper to the dry ingredients for a warm, cozy twist with a little kick.
• Orange Chocolate Ganache Topping: Swap the frosting for a quick ganache made with dark chocolate and orange-infused cream for a more decadent finish.
• Personal favorite: I once added finely chopped candied ginger to the batter for an extra pop of flavor. It was unexpected but wow, what a hit!

Serving & Storage Suggestions

Serve this cake slightly chilled or at room temperature for the best texture. The creamy orange frosting is luscious when it’s just a little cool but soft enough to melt in your mouth.

This cake pairs beautifully with a cup of black tea, a bold espresso, or even a glass of sparkling wine for celebrations. For a fun twist, top slices with fresh berries or a dollop of whipped cream.

Store leftovers tightly covered in the fridge for up to 4 days. The flavors actually deepen overnight, making it even better the next day. You can freeze individual slices wrapped in plastic and foil for up to 3 months—just thaw in the fridge overnight and bring to room temp before serving.

Reheat gently in the microwave for about 15 seconds if you want that fresh-baked warmth back without melting the frosting.

FAQs

Can I make this cake a day ahead?

Absolutely! The flavors actually deepen overnight. Just keep it covered tightly in the fridge and bring it to room temperature before serving.

Yes, you can freeze individual slices wrapped well in plastic wrap and foil for up to 3 months. Thaw in the fridge overnight before enjoying.

Is there a vegan version of this cake?

Definitely! Use dairy-free butter and cream cheese alternatives, and replace buttermilk with a plant-based milk plus a splash of vinegar.

Frosting can get runny if the cake is still warm or if too much orange juice is added. Make sure the cake is completely cool before frosting and add juice gradually.
