Ingredients for australian frog cake

Eight simple ingredients, one iconic Aussie dessert—crispy, citrusy, and unforgettable.

The flour and sugar are your foundation, but the citrus is what makes this cake sing. Freshly grated orange zest from organic oranges at Whole Foods or your local market adds that signature tang—none of that pre-grated stuff from the jar. For the butter, Plugrá or Land O'Lakes work great, but make sure it's cold when you cube it. The baking powder? Clabber Girl is my go-to—it's reliable and double-acting. Pro tip: Sift everything together before mixing to avoid lumps, and don't skip the zest. That's where the magic happens.

No fresh citrus? Bottled orange juice with extra lemon juice will work in a pinch, but you'll lose that bright, fresh flavor. Running low on powdered sugar for the glaze? Blend regular sugar in a food processor for a quick fix. The frog mold is non-negotiable for that iconic shape—Amazon or specialty baking stores carry them. No mold? A small bundt pan in a pinch, but the texture won't be quite the same. And if you're feeling fancy, add a splash of vanilla extract to the batter for extra depth.

This cake is all about the steam—don't skip it! Line your frog mold with parchment paper before baking to make unmolding easier. Store leftovers in an airtight container at room temperature for up to 3 days, or freeze the whole cake for 1 month. The glaze sets quickly, so add it right before serving. Trust me, the first slice is worth the wait—crispy outside, tender inside, and bursting with citrus.

Step-by-step instructions for Australian frog cake

Here's how to create that iconic golden dome with crispy layers and citrusy magic.

Sift the 2 cups all-purpose flour with the 2 tsp baking powder and 0.5 tsp salt into a large mixing bowl. In a separate bowl, cream the 1 cup cold cubed butter and 1.5 cups granulated sugar on medium speed until light and fluffy—about 3-4 minutes. You'll know it's ready when the mixture nearly doubles in volume and looks pale.

Add the 4 whole large eggs one at a time, mixing well after each addition. Stir in the 1 tbsp orange zest, 0.5 cup orange juice, and 2 tbsp lemon juice until fully combined. Gradually fold in the dry ingredients until just mixed—don't overmix or the cake will be dense. The batter should be thick but pourable, with a vibrant citrus aroma that fills your kitchen.

Grease the whole frog mold thoroughly with butter or oil, then place it in a large steamer basket. Pour the batter into the mold, tapping gently to remove air bubbles. Add the 0.5 cup water to the steamer pot and bring to a gentle simmer over medium heat.

Place the steamer basket with the mold on top and cover with a lid. Steam for 45-50 minutes until the cake springs back when pressed gently in the center. The top should be golden brown with a crackly crust—this is your golden dome forming. Be careful not to oversteam or the cake will become soggy. The citrus flavors will intensify as it steams, creating that signature tangy profile.

While the cake steams, prepare the glaze by whisking together the 1 cup powdered sugar with 2-3 tablespoons of the citrus juices from the batter (or additional orange juice if needed) until smooth. The glaze should be thick enough to coat the back of a spoon but still drizzle easily. This glaze will create that signature glossy finish and add extra citrus brightness.

Here's the thing—this glaze isn't just for looks. It helps set the cake's structure after it's removed from the mold. The powdered sugar creates a delicate crust that contrasts beautifully with the cake's texture. You'll want to work quickly once the cake is ready to apply the glaze while it's still warm.

Remove the steamer from heat and let the cake rest in the mold for 5 minutes before carefully unmolding. Run a thin knife around the edges of the mold to loosen the cake, then invert it onto a serving plate. The cake should pop out easily if properly steamed—if it sticks, it needs more time in the mold.

Immediately brush or drizzle the warm cake with the powdered sugar glaze, working quickly to cover all surfaces. The glaze will soak in slightly, creating that signature crispy exterior while keeping the interior moist. The citrus flavors will mingle beautifully with the cake's natural sweetness, creating that perfect balance that makes this cake legendary. Serve immediately while still warm for the best texture and flavor experience.

Essential equipment for this dish

Steam Basket Essentials

The heart of your frog cake lies in proper steaming, so invest in a high-quality steam basket that fits your pot snugly. I recommend a stainless steel one from Williams Sonoma—it distributes heat evenly and prevents warping. The basket should have a tight-fitting lid to trap steam, and never use a perforated steamer insert that lets steam escape. 🌡️

For best results, use a heavy-bottomed pot (like Le Creuset) that holds at least 3 quarts of water. The pot should be no wider than the basket—if it is, steam will escape from the sides. I’ve seen home cooks use double boilers in a pinch, but they’re not ideal for the even heat distribution this cake demands.

Frog Mold Must-Haves

The frog mold is non-negotiable for that iconic dome shape. Look for aluminum or stainless steel molds (avoid non-stick—they can’t handle steam heat). Amazon and specialty baking stores carry them, but if you’re in Australia, Kmart or Big W often stock them. Pro tip: Choose a mold with removable sides for easier unmolding. 🍰

If you can’t find a frog mold, a small bundt pan in a pinch—but the texture won’t be the same. The frog mold’s unique shape creates the crackly crust and tender interior that define this cake. I’ve tried substitutes, and nothing matches the real deal.

Citrus Tools for Brightness

Fresh citrus is key, so grab a microplane for zesting—it’s faster than a grater and yields finer texture. I love the OXO Good Grips model for its precision. For juicing, a handheld citrus reamer (like Bartender’s Dream) gives you more control than a juicer, especially for small batches. 🍊

Store-bought citrus juice won’t cut it—freshly squeezed is a must. If you’re short on time, notre dame brand orange juice (from the refrigerated section) is the closest substitute, but it lacks the bright acidity of fresh. The zest should be finely grated—no chunks!

Mixing and Measuring

A stand mixer with a paddle attachment (like KitchenAid) makes creaming butter and sugar effortless, but a hand mixer works too. For sifting dry ingredients, a fine-mesh sieve (like Norpro) ensures no lumps. I’ve seen cooks skip sifting, but it’s worth the extra 30 seconds—it prevents a dense cake. ⚡

Use a digital kitchen scale for accuracy, especially with butter and sugar. I weigh my butter in grams (225g for 1 cup) to avoid packing issues. For measuring citrus juice, a liquid measuring cup with markings ensures precision—no eyeballing here!

Glaze Application Tools

A small offset spatula (like Ateco) is perfect for spreading the powdered sugar glaze evenly. For drizzling, a pastry brush with soft bristles (like Silpat) prevents clumping. The glaze should be thick but pourable—adjust with extra citrus juice if needed. 💫

Work quickly when glazing—the cake’s warmth helps the glaze set faster. If the glaze thickens too much, thin it with 1 tsp hot water. A fine-mesh strainer (like Oxo) catches any lumps before application, ensuring a smooth finish.
