Step-by-Step Cooking Directions

Preheat & Prepare
Preheat your oven to 180 °C (360 °F). Generously grease a 20×20 cm (8×8-inch) baking dish with butter or oil.
Soak the Oats
In a mixing bowl, combine 1 cup oats, 150 ml milk, and 1 tsp vanillin or vanilla extract. Stir well, then let rest 10–15 minutes so the oats absorb the liquid and soften.
Prepare the Apples
While the oats soak, peel, core, and chop 2 apples into 1 cm cubes. Optionally toss apple pieces with a pinch of cinnamon or nutmeg for added warmth.
Chop the Walnuts
Roughly chop 50 g walnuts and set aside. Reserve a few walnut halves for garnish if desired.
Mix in Eggs
Crack 2 eggs into a small bowl, beat lightly, then whisk into the soaked-oats mixture until fully combined.
Combine Oats, Apples & Nuts
Fold chopped apples and walnuts into the oat-egg batter, ensuring even distribution.
Transfer & Top
Pour the mixture into the prepared baking dish, smoothing the surface. Sprinkle 2 tbsp sliced almonds (and reserved walnut halves) evenly over the top.
Bake
Bake in the center of the preheated oven for 45 minutes, until the top is golden and firm and a toothpick inserted into the center comes out clean.
Rest & Slice
Remove from oven and let cool in the dish 10 minutes. Slice into squares or wedges and serve warm or at room temperature.

Origins and Popularity

Baked oatmeal and fruit-nut bakes have roots in European porridge traditions, where oats were a staple grain. In the 20th century, American home cooks began adding eggs and baking the porridge mixture for convenient, make-ahead breakfasts. Variations featuring apples and nuts evoke autumnal flavors of apple pies and walnut loaves. The modern health-food movement embraces baked oatmeal for its balanced macros and customizable nature, while food blogs and social media have popularized these dishes as “breakfast cakes” that function like cake without refined sugar.
