Ingredients

• 1 cup rolled oats

• 150 ml warm milk (about 2/3 cup)

• 2 medium apples, peeled and grated

• 20 g butter (about 1.5 tablespoons), melted

• A pinch of vanillin or 1/2 tsp vanilla extract

• 2 eggs

• 50 g chopped nuts (walnuts, almonds, or pecans)

• 1 tbsp avocado oil (for greasing or drizzling)

Step-by-Step Cooking Directions

1. Prepare the Oat Base
Preheat your oven to 180°C (350°F). In a mixing bowl, combine 1 cup of rolled oats with 150 ml of warm milk. Let the oats soak for about 10 minutes to soften slightly.

2. Grate and Add the Apples
Peel and grate 2 medium apples and add them to the oat-milk mixture. Stir to combine evenly.

3. Add Eggs and Flavoring
Crack 2 eggs into the bowl and mix well. Add 20 g of melted butter, a pinch of vanillin (or 1/2 tsp vanilla extract), and stir until the mixture is cohesive.

4. Add the Nuts
Roughly chop 50 g of your choice of nuts and fold them into the mixture for added texture and crunch.

5. Grease and Pour
Lightly grease a baking dish (about 8×8 inches) with avocado oil. Pour the oat and apple batter into the dish and spread evenly with a spatula.

6. Bake
Place in the preheated oven and bake for 30 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean.

7. Cool and Slice
Allow to cool for about 10 minutes before slicing into bars or squares. Serve warm or at room temperature.

Ingredient Spotlight: Oats

Oats are a nutritional powerhouse rich in soluble fiber, particularly beta-glucan, which has been shown to lower cholesterol and improve blood sugar levels. They’re also high in protein compared to other grains and are naturally gluten-free (though make sure they’re certified GF if needed). In baking, oats provide structure, chewiness, and a mild, nutty flavor that pairs beautifully with fruits and spices.
