Preparation Guide

Ingredients

• 2 cups (160–170 g) rolled oats (old-fashioned)
• 2 cups (480 ml) milk (use 2% or swap almond/soy for dairy-free)
• 2 large eggs, beaten
• 1/3 cup (80–85 ml) pure maple syrup or honey (reduce for less sweetness)
• 2 medium apples (about 360 g total), peeled and diced (Fuji, Honeycrisp, or Gala work well)
• 2 tbsp unsalted butter, melted (or coconut oil for dairy-free)
• 1 tsp vanilla extract
• 2 tsp ground cinnamon
• 1 tsp baking powder
• 1/4 tsp fine sea salt
• 1/2 cup (50 g) chopped walnuts (optional; substitute pecans or sunflower seeds for nut-free)

Optional toppings and substitutions

• 1/4 cup raisins or chopped dried apricots (stir into batter)
• 1/4 cup Greek yogurt or plant-based yogurt (for serving)
• Zest of 1 orange for brightness
• 1 mashed ripe banana to replace some syrup for natural sweetness

Step-by-step Instructions

1. Preheat the oven to 375°F (190°C). Lightly grease an 8×8-inch (or similar) baking dish with butter or oil.
2. In a large bowl, whisk together the milk, beaten eggs, maple syrup, melted butter, and vanilla until smooth.
3. Stir in the rolled oats, cinnamon, baking powder, and salt until evenly combined. Let the mixture sit for 5 minutes so the oats begin to hydrate.
4. Fold in the diced apples and chopped walnuts (if using), making sure they’re evenly distributed. If you like extra fruit, gently fold in raisins or chopped dates now.
5. Pour the mixture into the prepared baking dish and smooth the top with a spatula. Press a few thin apple slices or a sprinkle of cinnamon on top for presentation.
6. Bake for 35–40 minutes, until the top is golden and a toothpick inserted near the center comes out mostly clean (a few moist crumbs are okay). Avoid overbaking to keep the center creamy.
7. Remove from the oven and let rest 10 minutes; the bake will firm slightly as it cools. Serve warm with yogurt, a drizzle of milk or extra maple syrup, and an extra sprinkling of walnuts or seeds.

Practical tips

• Avoid overmixing after adding the oats—stir just until combined to keep texture tender.
• Check doneness at 30 minutes if using a convection toaster oven; smaller ovens can run hot.
• For an extra custardy texture, increase the milk by 1/4 cup and bake the same time.
• If using a very sweet apple variety, reduce maple syrup by 2 tbsp.

Serving Suggestions

• Simple morning bowl: warm slice with a pat of butter (or vegan spread) and a splash of milk.
• With yogurt and fruit: top with Greek yogurt, a spoonful of apple compote, and toasted seeds for extra protein.
• Brunch spread: serve alongside scrambled eggs, smoked salmon, or a light green salad for a balanced brunch.
• Snack or dessert: enjoy slightly cooled with a scoop of vanilla ice cream or whipped cream.
• Cozy pairings: this bake pairs beautifully with a mug of chai, dark roast coffee, or a spiced apple cider—ideal for crisp mornings. If you’re styling a breakfast corner for autumn, these cozy autumn decor ideas for small spaces can help set the scene.

Shelf Life & Storage

• Room temperature: Cover the dish tightly and keep at room temperature for up to 24 hours (ideal if serving that day).
• Refrigeration: Store in an airtight container for up to 4 days. Reheat individual portions in the microwave (30–90 seconds) or oven at 300°F (150°C) until warmed through.
• Freezer: Freeze portions in airtight containers or wrapped in foil + a freezer bag for up to 3 months. Thaw overnight in the refrigerator and reheat before serving.
  Follow USDA/CDC guidance on storing cooked foods to reduce food-safety risks; cool the bake promptly and refrigerate within two hours of baking.

Chef’s Advice

• Oat selection: Old-fashioned rolled oats give a satisfying texture—avoid instant oats if you want some chew and structure.
• Apples: Choose a firm, slightly tart apple (Fuji or Honeycrisp) so the pieces hold shape once baked.
• Texture cue: The center should be set but not dry—if a spoon pushes through and the bake feels slightly custardy, it’s done. Carryover heat will finish it.
• Nut swaps: For a nut-free version, replace walnuts with toasted pumpkin seeds or extra fruit for crunch.
• Sweetness control: Start with 1/4 cup maple syrup if you prefer less sweet, and add a drizzle when serving if desired.

Recipe Variations

• Dairy-free & Vegan: Use almond or oat milk, replace eggs with 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let sit 5 minutes), and swap butter for coconut oil. Bake as directed.
• Gluten-free: Use certified gluten-free rolled oats and ensure any add-ins (like baking powder) are labeled gluten-free.
• Pumpkin Spice Twist: Replace one apple with 1/2 cup pumpkin puree, add 1/2 tsp nutmeg, and reduce milk by 2 tablespoons. Top with toasted pepitas.
• Apple-Cranberry Festive: Fold in 1/2 cup fresh or frozen cranberries and a tablespoon of orange zest for holiday color and bright acidity.

All Your Questions Answered

Q: Can I make this ahead and bake in the morning?
A: Yes—mix everything, cover, and refrigerate overnight. Bake from chilled; add a few extra minutes to the baking time.

Q: What if I don’t have eggs?
A: Use a flax “egg” (1 tbsp ground flaxseed + 3 tbsp water per egg) or a commercial egg replacer. The texture will be slightly different but still tasty.

Q: How can I reduce the sugar without losing texture?
A: Cut maple syrup to 1/4 cup and add a mashed banana for natural sweetness, or use a sugar substitute suitable for baking. Taste apples first; tart apples need less added sweetener.

Q: Can I halve the recipe for two people?
A: Absolutely—use a smaller oven-safe dish (6×6-inch) and check for doneness slightly earlier.

Q: What’s the best way to reheat without drying out?
A: Microwave briefly covered with a damp paper towel or reheat at 300°F (150°C) wrapped in foil with a splash of milk.
