Ingredients
The foundation of this bake is a blend of whole‑grain oats and a custardy egg‑milk mixture that keeps the dish light yet satisfying. Fresh apples provide juicy pockets of flavor, while honey adds a natural glaze that caramelizes during baking. Warm spices like cinnamon and nutmeg deepen the aromatic profile, and a handful of toasted walnuts introduces a pleasant crunch.
Dry Ingredients
- 1 ½ cups rolled oats
- ¼ cup whole‑wheat flour
- 1 ½ teaspoons baking powder
- ½ teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- ¼ teaspoon sea salt
Wet Ingredients & Sweeteners
- 2 large eggs
- 1 ¼ cups low‑fat milk
- ¼ cup unsalted butter, melted
- ⅓ cup honey
- 1 teaspoon pure vanilla extract
Fruit & Crunch
- 3 medium apples, peeled, cored, and sliced thin
- ¼ cup chopped walnuts (optional)
These ingredients work together to create layers of texture and flavor. The oats absorb the custard, turning soft yet retaining a slight chew, while the apples release juices that mingle with honey, forming a glossy glaze. The melted butter enriches the crumb, and the spices weave a warm, inviting aroma that makes every bite feel like a hug.
Step-by-Step Instructions

Preparing the Fruit
Start by preheating the oven to 375°F (190°C). In a medium bowl, toss the sliced apples with 2 tablespoons honey, a pinch of cinnamon, and a drizzle of melted butter. This coating helps the apples caramelize and prevents them from drying out during baking. Spread the apples evenly in the bottom of a greased 9‑inch square baking dish.
Mixing the Oat Custard
In a large mixing bowl, whisk together 2 large eggs, 1 ¼ cups milk, ⅓ cup honey, and 1 teaspoon vanilla until smooth. Add the dry ingredients—rolled oats, flour, baking powder, cinnamon, nutmeg, and salt—stirring just until incorporated. Over‑mixing can make the bake dense, so stop once you see a uniform batter.
Assembling the Bake
- Layer the batter. Gently pour the oat custard over the apple layer, using a spatula to spread it evenly. The batter will sink slightly into the apple juices, creating a moist base.
- Add the topping. Sprinkle the chopped walnuts (if using) across the surface. Drizzle the remaining 1 tablespoon honey over the top; this will form a glossy, caramelized crust.
- Bake. Place the dish in the preheated oven and bake for 30‑35 minutes, or until the edges are golden and a toothpick inserted into the center comes out clean. The top should be lightly browned and fragrant.
- Rest before serving. Allow the bake to rest for 5‑7 minutes after removing it from the oven. This short rest lets the custard set, making it easier to cut clean squares.
Final Touches
Dust each serving with a light sprinkle of extra cinnamon or a drizzle of warm honey for added shine. Serve the bake warm, paired with a dollop of Greek yogurt or a splash of cold milk for a balanced breakfast experience.
Tips & Tricks
Perfecting the Recipe
Uniform Apple Slices: Use a mandoline or a sharp knife to achieve even slices; this ensures consistent caramelization across the dish.
Don’t Over‑mix the Batter: Stir just until the dry ingredients disappear. Over‑mixing activates gluten in the flour, resulting in a tougher texture.
Room‑Temperature Ingredients: Let the milk and eggs sit out for 10 minutes before whisking; this promotes even baking and a smoother custard.
Check Early: Begin checking for doneness at the 28‑minute mark; ovens vary, and you want a golden top without burning.
Flavor Enhancements
Add a teaspoon of freshly grated ginger to the apple mixture for a subtle zing, or fold in a handful of dried cranberries for extra tartness. A splash of maple syrup in place of half the honey introduces a richer, wood‑sycamore note that pairs beautifully with the oats.
Common Mistakes to Avoid
Avoid using overly ripe apples—they release too much juice and can make the bake soggy. Also, don’t skip the resting period; cutting the bake while it’s still steaming leads to crumbly squares and lost juices.
Pro Tips
Toast Oats First: Lightly toast the rolled oats in a dry skillet for 3‑4 minutes; this adds a nutty depth that elevates the overall flavor.
Use a Glass Baking Dish: Glass retains heat evenly, helping the custard set without developing a dry edge.
Finish with a Citrus Zest: A light sprinkle of orange zest just before serving brightens the sweet profile and adds a fragrant finish.
Store in Separate Layers: If making ahead, keep the apple layer and oat custard in separate containers; combine and bake when ready for optimal texture.
Variations
Ingredient Swaps
Swap the classic Granny Smith apples for tart Pink Lady or sweet Fuji for a different flavor balance. Replace rolled oats with quinoa flakes for extra protein, or use almond butter instead of regular butter for a nutty twist. For a festive spin, stir in dried cranberries or chopped dried apricots.
Dietary Adjustments
For a vegan version, substitute the eggs with a flax‑egg (1 tablespoon ground flax + 3 tablespoons water) and use plant‑based milk such as oat or almond. Use coconut oil or vegan butter in place of dairy butter. To keep it gluten‑free, replace the whole‑wheat flour with a gluten‑free blend or extra oat flour.
Serving Suggestions
Pair the bake with a dollop of Greek yogurt or a spoonful of ricotta for creamy contrast. A side of fresh mixed berries adds acidity, while a drizzle of extra honey brightens the plate. For a brunch buffet, serve alongside scrambled eggs and toasted sourdough.
Storage Info
Leftover Storage
Allow the bake to cool completely, then cut into squares and place them in an airtight container. Store in the refrigerator for up to four days. For longer keeping, wrap individual portions in plastic wrap, then foil, and freeze for up to three months; this preserves both texture and flavor.
Reheating Instructions
Reheat refrigerated leftovers in a pre‑heated 350°F oven for 10‑12 minutes, covered with foil to prevent drying. For frozen portions, thaw overnight in the fridge, then follow the same oven method. A quick microwave on medium power (30‑45 seconds) works for single servings, but the oven retains the best crust.
