with cinnamon & oats
Mixed Berry Crumble – This warm and comforting dessert combines sweet & tangy berries with a buttery, biscuit-like topping. Served warm with cold custard, perfect for any season, it’s especially wonderful for using peak-season berries or rescuing fruit that’s slightly past its prime.
Why This Recipe Works
The success lies in the balance between tart berries and sweet, buttery topping. A touch of cinnamon adds warmth, while cornstarch ensures the perfect jammy consistency. The cream in the topping creates tender, flaky layers that contrast beautifully with the fruit.
Understanding Key Components
Fresh Berry Compote:
- Fresh berries provide bright flavor and natural pectin. You can substitute with a combination of raspberries, blackberries, blueberries, strawberries. Frozen berries can also be used and no need to be thawed before use. Stone fruits such as peaches, plums and cherries are also great options.
- Cornstarch is our thickening agent that prevents the compote from being too watery. Substitution option: potato starch
- Lemon zest brightens and enhances berry flavor. You can omit this if you prefer a less sour taste. Can substitue with other citrus fruits.
- Sugar amount can be adjusted to fruit sweetness. Alternative sweeteners: Brown sugar, honey, maple syrup
The Crumble Topping
A buttery, biscuit-like crown that turns golden and crisp:
- Cold butter creates flaky and crumbly texture. Make sure your butter is cold. We don’t want the butter to melt as it will not result in a crumbly texture.
- Cream provides richness and tenderness. Alternatives: half-and-half
- Flour provides structure can be substituted with whole wheat flour for a nuttier taste or oats.
- Baking powder ensures proper lift. Cannot be substituted
- Sugar adds sweetness and helps browning. Can substitute with Brown sugar for caramel notes
- Cinnamon adds subtle warmth and flavour. Can be substituted with vanilla extract for a different flavour profile.
- Cream wash creates golden crust
Tips!
- Keep butter very cold. We don’t want the butter to melt as it will not result in a crumbly texture. Use your fingertips when rubbing the butter into the flour as the palm of your hands have a lot of warmth.
- Crumble should resemble wet sand
- Leave space between topping dollops so the colour of your fruit peaks through when baked! It’s visually better but optional
- Place the baking dish with berry cobbler onto a baking sheet to catch bubbling or drippings from falling onto your oven floor.
- Let rest 15 minutes before serving.
