If you are craving a decadent, fudgy chocolate cake but don't want to deal with a mess of bowls or waiting for the oven to heat up, this High-Protein One-Pan Chocolate Cake is your new holy grail. This entire recipe is mixed and cooked right inside a single non-stick skillet on your stovetop!
By using a ripe banana and apple purée, we keep the cake incredibly moist and naturally sweet without adding heaps of refined sugar or heavy oils. The real magic happens right after cooking: poking holes in the cake and soaking it with milk creates a melt-in-your-mouth texture, which is then topped with a glossy, 2-ingredient chocolate shell. It’s the ultimate lazy-day fitness dessert!
Prep time, Cook time, Servings
Prep time: 5 minutes
Cook time: 10-12 minutes (on low heat)
Yield: 1 large single-serve cake (or 2 servings to share)
Ingredients
For the One-Pan Chocolate Cake Base
1 ripe banana
2 tbsp apple purée (applesauce)
1 large egg
1 to 1.5 scoops protein powder (chocolate or vanilla whey/casein blend)
2 tbsp all-purpose flour (or oat flour)
1 tbsp cocoa powder (unsweetened)
A splash of vanilla extract
A splash of milk (just enough to thin the batter to a smooth consistency)
¼ cup milk (reserved to pour over the cake after cooking)
For the Glossy Chocolate Topping
¼ cup dark chocolate chips (or chopped dark chocolate)
1 tbsp coconut oil
Step-by-Step Instructions
1. Mash and Mix in the Pan
Place your non-stick skillet on the counter (off the heat). Drop in the ripe banana and mash it thoroughly with a fork until smooth. Add the apple purée, egg, flour, protein powder, cocoa powder, vanilla extract, and a small splash of milk. Whisk everything directly in the pan until you have a smooth, rich chocolate batter. Clean the edges of the pan with a spatula if needed.
2. Cook Low and Slow
Place the skillet on your stovetop over really low heat and cover it with a lid. Let it cook undisturbed for about 8 to 10 minutes. You’ll know it’s ready when the edges are set and the top looks matte and cooked through.
3. The Poke and Poke-Milk Soak 🥛
Remove the pan from the heat. Take a fork and gently poke holes all across the top of the warm chocolate cake. Pour the reserved ¼ cup of milk evenly over the surface. The cake will completely absorb the milk through the holes, making it unbelievably juicy and rich.
4. Melt the Chocolate Ganache
In a small microwave-safe bowl, combine your chocolate chips and 1 tablespoon of coconut oil. Microwave in 20-second bursts, stirring in between, until the chocolate is completely melted, glossy, and smooth.
5. Top and Serve
Pour the melted chocolate glaze directly over the soaked cake in the pan, spreading it evenly to the edges. Let it cool for a couple of minutes so the chocolate sets slightly, then slice it right out of the skillet and enjoy your warm, fudgy masterpiece!
