Warm berries and golden crunch come together for a cozy start to your day.

Corn Flake, Oat, and Strawberry Breakfast Crumble

Start your morning—or cap your evening—with a crumble that mixes the nostalgia of corn flakes, heartiness of oats, and sweetness of real strawberries. This vibrant, texture-packed dish is more than just a dessert—it’s a celebration of contrast: hot and cold, tart and sweet, creamy and crunchy.

Why Choose a Breakfast Crumble?

Crumble-style breakfasts are having a movement of their own. They’re lighter than cake and more festive than oatmeal, packing plenty of fruit and a satisfying crunch. Serving breakfast crumble is also a clever way to transform simple pantry staples into something memorable with minimal fuss and maximum reward.

Versatility: Works for breakfast, brunch, or dessert.
Customizable: Swap in your favorite fruits or cereal.
Make-ahead friendly: Can be prepped the night before and baked fresh in the morning.

What Makes This Crumble Special?

The secret is in the corn flake and oat topping. The corn flakes toast as the crumble bakes, coaxing out rich, nutty flavors that offset the sweet strawberries. A touch of brown sugar and hints of spice round out the crunch, creating a topping that stays crisp and golden even when cooled.

Corn flakes offer a unique, shattering crunch.
Oats bring heartiness and homey flavor.
Butter and brown sugar bond the topping and boost caramel notes.
A little salt heightens the sweet and tart flavors of the fruit.

Step-by-Step Instructions

1. Prepare the Strawberry Layer

Preheat oven to 375°F (190°C).
Hull and quarter fresh strawberries (about 32 oz or 900g).
In a large bowl, toss strawberries with lemon juice, white sugar, cornstarch, and vanilla extract.
Spread evenly in a greased 9×9-inch or 11×7-inch baking dish.

2. Mix the Crumble Topping

In a separate bowl, combine oats, corn flakes, brown sugar, flour, cinnamon, and salt.
Pour in melted unsalted butter and mix until clumps form.
Spoon topping over the strawberry mixture, making sure to cover edges as well as the center.

3. Bake and Serve

Bake for 35–40 minutes until the top is golden and fruit juices bubble around the edges.
Let cool for 5-10 minutes before serving to allow syrup to thicken slightly and flavors to intensify.
Enjoy warm, ideally with a scoop of vanilla ice cream or whipped cream.

Make-Ahead, Storage, and Reheating Tips

Make-ahead: Assemble crumble (unbaked) and keep topping and fruit separate if possible. Store in the fridge overnight, combine and bake in the morning.
Storage: Cover and refrigerate for up to 3 days. Note that the topping may lose some crunch over time.
Reheating: Warm individual servings in the oven or microwave. For best crispness, reheat in the oven at 350°F covered with foil until hot, then remove foil briefly to recrisp the top.
Freezing is not recommended for assembled crumble due to loss of topping texture when thawed.

Serving Suggestions

The strawberry breakfast crumble shines both as a decadent weekend brunch and a comforting dessert. Its flexibility makes it the “little black dress” of fruit bakes.

Serve warm with ice cream or whipped cream for dessert.
Pair with vanilla Greek yogurt or a splash of cold milk for breakfast.
Add fresh berries on top for extra color and brightness.
Drizzle over some honey, maple syrup, or a dusting of powdered sugar if you prefer it a touch sweeter.

Tips, Tricks, and Variations

Use frozen strawberries if fresh are unavailable—simply increase the cornstarch to help thicken the extra juices. Do not thaw before using.
Try mixed berries such as raspberries, blueberries, or blackberries for a seasonal twist.
Infuse with spices: Swap or add ground cardamom, nutmeg, or ginger to the topping for deeper spice nuances.
Add chopped nuts (like almonds or pecans) to the topping for extra crunch and nutrition.
Sprinkle in lemon or orange zest for a fragrant aroma.
If you’re gluten-free, use certified gluten-free oats and a 1:1 gluten-free flour blend.

Nutrition Profile

This crumble is a wholesome balance of fiber and flavor, but it is a treat—best enjoyed as part of a balanced diet. For those interested in nutrition breakdown, a typical serving provides:

Calories: ~400–450 (excluding toppings like ice cream)
Fat: 15g (mostly from butter)
Carbohydrates: approx. 75g (including fruit’s natural sugars)
Fiber: 5g+
Protein: 4–5g
Vitamin C: very high (over 100% daily value per serving)

If you’re watching sugar, reduce added sugar in the filling or eliminate a portion of the brown sugar in the topping. Swapping in a portion of whole grain flour or reducing butter can also lighten the recipe.

Common Mistakes and How to Prevent Them

Topping Burns Before Fruit Cooks: Tent loosely with foil for the last 10 minutes if topping darkens too quickly.
Watery Filling: Ensure you bake until juices bubble at the edges and thicken; underbaking leaves a soupy base.
Tough or Dry Topping: Don’t overbake—remove when fruit is bubbling and top is golden.
Too Sweet or Too Tart: Balance the sugar to your liking, especially if using very ripe or underripe fruit.

Frequently Asked Questions (FAQs)

Q: Can I use different fruits?

A: Absolutely. Any berries, peaches, plums, or even slightly tart apples work well—just adjust sugar and thickener accordingly.

Q: Can I make this vegan?

A: Substitute plant-based butter or coconut oil for the melted butter.

Q: How do I keep the topping crunchy?

A: Avoid covering with a lid or plastic when warm. Re-crisp topping briefly in the oven if needed before serving leftovers.

Q: Can I assemble the crumble the night before?

A: Yes—store fruit and topping separately for best texture, then combine and bake in the morning.

Q: Should I peel the strawberries?

A: No peeling needed. Just hull and quarter or halve them depending on size for even cooking.
