| All-Purpose Flour | 1.5 cups (180 g) | Sifted |
| Brown Sugar (Cassonade) | 3/4 cup (150 g) | Packed |
| Unsalted Butter | 3/4 cup (170 g) | Melted and cooled |
| Baking Powder | 1 teaspoon | To lighten the crumble |
| Ground Cinnamon | 1/2 teaspoon | For aroma |
| Salt | 1/4 teaspoon | Pinch |
Cheesecake & Fruit Filling
| Ingredient | Quantity | Preparation |
| Cream Cheese | 400 g | At room temperature |
| White Sugar | 1/2 cup (100 g) | Granulated |
| Egg | 1 large | At room temperature |
| Vanilla Extract | 1 teaspoon | Liquid |
| Mixed Fresh Berries (strawberries, raspberries, blueberries) | 2 cups (300 g) | Fresh, washed, and dried |
Step-by-Step Instructions
- Preheat and Prep the Pan: Preheat your oven to 350°F (175°C). Lightly grease a large 9×13-inch glass baking dish or line it with parchment paper.
- Make the Crumble Dough: In a large bowl, mix together the rolled oats, flour, brown sugar, baking powder, cinnamon, and salt. Pour in the melted butter and mix with a spatula or your fingers until a crumbly texture forms.
- Form the Crust: Firmly press about 2/3 of the crumble mixture into the bottom of the prepared dish to form a compact, even base. Reserve the remaining third for the top.
- Make the Cheesecake Filling: In another bowl, beat the cream cheese and white sugar with an electric mixer until smooth and creamy. Add the egg and vanilla, then beat on low speed just until incorporated.
- Assemble the Layers: Pour the cheese filling evenly over the oat base and smooth it out. Scatter the fresh berries harmoniously across the surface of the cream.
- Add the Top Crumble: Evenly crumble the remaining oat mixture over the berries, completely covering the filling.
- Bake: Bake at 350°F (175°C) for 40 to 45 minutes, until the top crumble is golden brown and the center is set.
- Cooling: Let the dish cool completely on a wire rack, then chill in the refrigerator for at least 2 hours before slicing into squares for a clean cut.
Best Tips
- Compact the Base: Use the flat bottom of a glass to firmly press down the bottom layer of crumble. This prevents the base from crumbling when sliced.
- Dry the Berries: After washing your fresh berries, gently pat them dry with paper towels to prevent excess moisture from entering the cake.
- Mandatory Chilling: Do not cut the cake while warm. Refrigerating allows the cream cheese layer to firm up properly.
Best Ingredient Options
- Sugar Variation: Muscovado or dark cane sugar adds a wonderful caramel note to the crumble.
- Gluten-Free Option: Use certified gluten-free rolled oats and replace the flour with a gluten-free baking flour blend.
- Butter Swap: You can substitute melted coconut oil for the butter for a lightly aromatic variation.
Recipe Variations
- Apple Cinnamon Crumble: Replace the mixed berries with thin slices of apples sautéed with cinnamon and a touch of maple syrup.
- Citrus Twist: Add the zest of an organic lemon into the cheesecake filling to enhance freshness.
- Peach & Raspberry Crumble: Combine diced fresh peaches with raspberries for a delicious summer flavor profile.
What to Serve With
- A scoop of macadamia nut vanilla ice cream or a dollop of homemade whipped cream.
- A long coffee, cappuccino, or bergamot black tea.
- A glass of fresh berry lemonade.
Make-Ahead Instructions
This cake is ideal to prepare the day before! An overnight stay in the refrigerator allows the cheesecake to develop all its flavors and yields clean, elegant slices.
Storage
- In the Refrigerator: Store the covered cake in its dish or an airtight container in the fridge for 4 to 5 days.
Reheating
- Serve Cold or Warm: This dessert is traditionally enjoyed cold straight from the fridge. If you prefer a warm crumble, microwave a single slice for 10 to 15 seconds.
Freezing
- Freezing: You can freeze individual squares. Wrap each slice tightly in plastic wrap, then place them in a freezer bag for up to 2 months. Thaw overnight in the refrigerator before serving.
Common Mistakes to Avoid
- Over-mixing the Filling: Do not over-beat the cheese mixture after adding the egg, as this incorporates too much air and can cause the creamy layer to crack.
- Cutting Too Soon: Attempting to slice the cake while still warm will cause the cheesecake layer to collapse.

Frequently Asked Questions
Can I use frozen berries? Yes, it is entirely possible. Do not thaw them first: add them still frozen after tossing them with a teaspoon of cornstarch to absorb excess juices.
Why is my top crumble lacking crunch? Make sure to follow the proportions of melted butter and bake the cake until the top turns a rich amber-golden color.
