It is officially strawberry season! I haven't gone out to pick strawberries yet but it's only a matter of time until my fridge is full of sweet and juicy fresh picked strawberries.

Healthy Strawberry Rhubarb Crisp is a great recipe for using up some of those berries. The sweet and juicy flavor of the berries combined with the tartness of the rhubarb make Healthy Strawberry Rhubarb Crisp a great summer treat. In fact this recipe is so healthy you could even choose to eat it for breakfast!

Instructions
Preheat oven to 350F. Lightly grease an 8x8 baking pan.

Wash strawberries and rhubarb. Remove stems from strawberries. Roughly chop strawberries and rhubarb. Transfer berries and rhubarb to a medium size bowl.

Optional: Add maple syrup to to the berries and rhubarb. Use a spoon to gently mix the maple syrup until it coats the berries and rhubarb. Skip this step if you prefer a more tart crisp.

Add cornstarch to to the berries and rhubarb. Use your hands to gently toss the berries and rhubarb until the cornstarch is evenly distributed.

In a medium size bowl, add oats, oat flour and cinnamon. Stir to combine. Add maple syrup. Use a spoon to mix the crumb mixture until the maple syrup is completely incorporated. The mixture will be quite sticky.

Add berry mixture to prepared baking pan. Spread mixture to the edges of the pan. Use your hands to evenly distribute the oat mixture on top of the berries. Cover the pan with foil.

Bake for 40 minutes. Remove foil and bake for an additional 15 minutes to brown the crisp. Remove from oven and let cool before cutting into slices. Makes 16 slices.
Hint: Make sure to cool the crisp completely before slicing because this allows the crisp to set. If you don't want to wait, you can serve the crisp while it's still warm but it will be a tad messy!
Substitutions
- Strawberries - In a pinch frozen strawberries can be substituted for the fresh strawberries. If using frozen strawberries be sure to thaw and drain the liquid from the strawberries before adding the other ingredients. If you do not drain the liquid, the crisp will be really messy.
- Rolled Oats - Quick oats can be substituted for the rolled oats. Do not use steel cut oats for this recipe.
- Oat Flour - All purpose flour can be used instead of oat flour.
Variations
- Gluten Free - Use certified gluten free oats and oat flour made from gluten free oats.
Equipment
8x8 Baking Pan - Be sure to use an 8x8 baking pan as the cooking time will change if you use a different size.
Storage
Healthy Strawberry Rhubarb Crisp can be stored in an airtight container in the fridge for up to three days.
Strawberry Rhubarb Crisp can be frozen in a freezer safe container for up to three months, however the topping will not maintain the crispiness after it has been frozen. Thaw in the fridge or at room temperature when ready to eat.
Top tip
