Oats, yogurt and eggs set into a soft custard in the oven, and the flavor map is up to you: cocoa stirred into one zone, matcha or kale powder into another, the middle left plain. Apple slices and dark chocolate squares are stood upright in the batter so every cut piece carries a cross-section. Baked, chilled overnight, then sliced, it eats like a slightly guiltless dessert.

One baking dish, three custard flavors. Cocoa, matcha and plain zones rise around apple slices, dark chocolate squares and nuts, then chill overnight so it slices like a soft cake.

Ingredients
| 35 g | rolled oats |
| 15 g | milk powder |
| 5 g | nut and seed flour blend |
| 10 g | chia seeds |
| 80 g | plain yogurt , plus a spoon of whey |
| 2 | eggs |
| 5 g | unsweetened cocoa powder |
| 5 g | matcha or kale powder |
| 6 squares | 100 percent dark chocolate |
| 0.5 | apple , cored, thinly sliced |
| 1 packet, about 25 g | mixed nuts |
| a handful | dark chocolate chips and black sesame, to top |
Method
- In a rectangular baking dish, stir the oats, milk powder, nut flour and chia with the yogurt and enough of its whey, or 10 to 20 ml of water, to make a thick, stirrable batter. Sweeten with a little sugar if you like.
- Beat in the eggs until smooth.
- Section the dish into thirds. Stir the cocoa into one third, the matcha powder into another, and leave the rest plain.
- Scatter black sesame over the surface and press the chocolate squares down into the batter, spaced apart.
- Tuck the apple slices into the gaps, then scatter the mixed nuts around the edges.
- Finish with a layer of chocolate chips.
- Bake at 160 degrees C for 30 minutes, then cool.
- Cover and refrigerate overnight. Loosen the edges with a spatula and turn the slab onto parchment.
- Slice with a serrated knife so each piece holds a whole square of chocolate at its center.
Notes
- Chilling overnight is what makes clean slices possible; warm, it collapses.
- Swap the zone powders freely: blueberry powder, coffee or cocoa all work.
