This is a layered ground pork and beef bake — three springform-pan rounds stacked and frosted with sweet potato and tomato paste, so it looks like a cake when you slice it. It feeds 12 people from a single oven session, which makes it genuinely useful for a crowd. The prep is straightforward: mix, bake, stack.
The short version of why this works
Two things carry this recipe. First, the sauce — tomato paste, fish sauce, apple cider vinegar, and warm spices — gets mixed directly into the raw meat before baking. That means seasoning reaches every bite, not just the surface. Second, using three separate springform pans instead of one large loaf cuts the bake time down significantly and gives you flat, even layers that actually stack cleanly. Both of those choices matter more than any single ingredient.
If something goes sideways
- Layers crack when you release the pans: Let the meat rest the full 10 minutes before unclipping. Rushing this is the main reason layers fall apart. Run a thin knife around the edge first if it looks stuck.
- Frosting is too loose to spread: Your potatoes held too much water. Drain them thoroughly, then let them steam-dry in the pot for two minutes off the heat before mashing. Add coconut milk one tablespoon at a time — you may not need all three.
- Meat reads under 160°F at 60 minutes: Springform pans vary in thickness. Check the center of each layer with an instant-read thermometer; ground pork and beef must hit 160°F (71°C). Add time in 5-minute increments rather than guessing.
- Layers slide when stacking: Make sure each layer is fully cooled and that the frosting between them is thick, not runny. A thin, even coat of sweet potato frosting acts as the glue — skip the white potato garnish on top if you’re short on time, since it adds a step without improving the flavor.
- Mushrooms make the mixture too wet: If your mushrooms released a lot of liquid during processing, spread the chopped mixture on a paper towel and press briefly before adding to the meat. Excess moisture leads to a spongy texture that won’t hold its shape when sliced.
Storage and reheating
Assembled or unassembled, this keeps in the fridge for up to 4 days in an airtight container. For longer storage, freeze individual slices wrapped tightly in plastic and then foil — they hold well for up to 2 months. Thaw overnight in the fridge before reheating. To reheat, place slices in a 325°F oven covered loosely with foil for about 15 minutes, or until the center reaches 165°F. The microwave works in a pinch but softens the sweet potato frosting considerably, so the oven is worth it if you have the time.

- 1 pound white button mushrooms - cleaned, 450g
Frosting Ingredients
1 pound Japanese sweet potatoes - 450g
Instructions
Prepare the Meat Layers
- Preheat the oven to 350°F / 175°C (180°C fan-forced). Grease three 8-inch (20cm) springform pans with coconut oil.1 tablespoon coconut oil
- Mix the salt, tomato paste, cinnamon, dry mustard, cayenne pepper, nutmeg, apple cider vinegar, fish sauce and water in a bowl to make a smooth sauce.1 teaspoon salt, 6 ounces tomato paste, 1/2 teaspoon cinnamon, 1 teaspoon dry mustard, 1 teaspoon fish sauce, 1/4 teaspoon nutmeg, 2 teaspoons apple cider vinegar, 1/4 teaspoon cayenne pepper, 1 cup water
- Pulse the garlic, mushrooms, and onion in a food processor until finely minced — about 8 to 10 pulses. Do not purée; you want small, visible pieces.1 medium yellow onion, 1 pound white button mushrooms, 3 cloves garlic
- In a large mixing bowl, mix the onion mixture, ground pork, ground beef, eggs, dried thyme, parsley, and sauce with each other.2 large eggs, 2 pounds ground pork (minced pork), 4 pounds ground beef (minced beef), 2 teaspoons dried thyme, 1 cup parsley
- Divide the mixture evenly among the three prepared springform pans, pressing down to level the tops. Bake for 40–45 minutes or until the internal temperature reaches 165°F / 74°C.
- Let the pans rest for 10 minutes, then carefully release and remove the springform sides. Use a sharp knife to trim any uneven edges from each layer so they stack evenly.
Make the Frosting
- Peel the potatoes and sweet potatoes and cut them into 1-inch (2.5cm) chunks. Place them in a medium saucepan and cover with cold water by about 1 inch.1/2 pound potatoes, 1 pound Japanese sweet potatoes
- Bring to a boil over high heat, then reduce to a simmer and cook for 15–20 minutes or until fork-tender. Drain well. Separate the potatoes from the sweet potatoes into two mixing bowls and mash both roughly with a fork.
- Add the 12 ounces (340g) of tomato paste to the mashed sweet potatoes. Whip with a hand mixer on medium speed, scraping down the sides of the bowl, until the frosting is completely smooth — about 2 minutes.12 ounces tomato paste
Assemble the Cake
- Place the first meat layer on a serving platter. Spread a generous layer of sweet potato frosting over the top and sides — it does not need to be perfectly smooth at this stage, but ensure full coverage.
- Stack the second meat layer on top and frost it the same way. Add the third and final layer and frost the top and sides completely.
- With a butter knife, smooth the sides of the frosting with a soft upward sweeping motion. Between strokes, it is good to clean the knife.
- Use gentle strokes across the diameter to smooth the top area of the cake.
- To make the rosettes, whip the plain mashed potatoes with the coconut milk using a hand mixer until smooth and stiff enough to hold its shape when piped. Add more coconut milk 1 teaspoon at a time if needed.3 tablespoons coconut milk
- Transfer the whipped potatoes to a piping bag fitted with a rosette tip. Pipe rosettes around the base and along the top edge of the cake.

Your questions, answered
Can I use all beef instead of the pork and beef mix?
Yes, 6 pounds of ground beef works fine. The pork adds a little extra fat and softness, so if you go all-beef, choose an 80/20 blend rather than leaner ground beef or the layers may turn out drier.
Can I make this the day before and assemble it cold?
Yes, and it actually holds together better when the layers are fully chilled. Bake and cool the layers the night before, refrigerate them uncovered so the surfaces firm up, then assemble and frost the next day before serving.
Do I need three springform pans, or can I use something else?
Three 8-inch springform pans are strongly recommended because the release mechanism lets you unmold the layers without breaking them. Standard cake pans lined with parchment can work in a pinch, but getting the layers out cleanly is much harder and you risk losing the shape you need for stacking.
