Normally we see fruit desserts throughout the spring and summer seasons, but Strawberry Rhubarb crisp can truly be made any time of the year! 

Both of these fruits are filled with antioxidants and packed full of vitamins and nutrients that have anti-inflammatory properties and have been shown to decrease risks of certain diseases. 

Did you know that frozen fruit is just as healthy as fresh? Fruits are picked and frozen at peak ripeness, and studies show that they retain a comparable vitamin, mineral, and phytochemical content to their fresh counterparts.

Crisp, Cobbler, Crumble: What’s the Difference?

Sometimes these terms are used interchangeably but there is actually a difference! All of these types of recipes usually contain fruit, but it’s the topping that makes the difference! 

A cobbler typically has a doughy, biscuit-like topping. When you think of cobblers you are probably thinking about your grandma’s traditional recipe that has been passed down for ages! 

Crumbles are more like a streusel topping, but they don’t contain any oats. 

If it’s a true crisp, it will definitely have oats in the topping!

Now let’s make the streusel topping! 

In a medium bowl, add the oats, flour, brown sugar, and 4 tablespoons of butter. Stir it all together until it’s combined well. Add additional butter ( one to two tablespoons) if it seems too dry.

Bake until the top of the crisp is golden, which will take about 35 to 50 minutes. 

Once it has finished baking, let it cool on a wire rack before serving. 

You can serve it warm or at room temperature!

What If I Don’t Have Whole Wheat Pastry Flour?

A nice substitute when you don’t have whole wheat pastry flour is a 1:1 ratio of all purpose flour and whole wheat flour.

Can You Use Frozen Strawberries and Rhubarb? 

If you want to make this fruit crisp and you don’t have a chance to grab fresh strawberries and rhubarb, or maybe they are out of season you can use frozen instead. 

Be sure that the fruit is thawed completely and drained so that the crisp does not come out soggy from the excess liquid.
