Easy Mixed Berry Bars

I love crumble or streusel toppings and the bigger the crumbles, the happier I am. It’s even better when the crust and crumble topping are one and the same. One less step, and one less bowl to wash, and a big timesaver and that’s the case here.  This an easy, no-mixer mixed berry dessert recipe that takes just minutes to make. I merged three of my favorite berry bars into one to create these bars: Blueberry Pie Bars, Strawberry Lemonade Bars, and Blueberry Oatmeal Crumble Bars. Between the buttery firm crust, juicy berries, sandy crumbles, and crunchy Fisher walnuts, there are so many wonderful textures and flavors in every bite!

Ingredients in Mixed Berry Bars

For these berry crumble bars, you’ll need:

How to Make Mixed Berry Bars

This is such a simple but impressive dessert with mixed berries! To make the berry bars, follow these steps:

Should I Use Fresh or Frozen Mixed Berries? 

I generally bake with frozen fruit because it’s cheaper and readily available year-round, but of course you can use fresh. I used a combo of strawberries, blueberries, raspberries, and blackberries. Baking time will vary based on if your berries are fresh, frozen, and how juicy they are. Watch your bars and not the clock when evaluating doneness.

Can I Double This Recipe? 

Yes! You can double the ingredients and bake the bars in a 9×13-inch pan. 

Tips for the Best Mixed Berry Bars

I used frozen berries in this mixed berry dessert and the pan was very cold going into the oven and baked for 68 minutes. If using fresh berries, baking time will likely be reduced; start checking at 40 minutes. Watch your bars, not the clock, when evaluating doneness. After the bars have cooled, I placed the pan in the fridge 2 hours before slicing to ensure clean, neat cuts. If you try to slice the bars before they’ve cooled completely, they’ll be extremely messy and could fall apart.  The crumble bars will keep airtight at room temperature for up to 1 week, in the fridge for up to 10 days (they’re good slightly chilled if you like chilled pie and I store them in the fridge), or in the freezer for up to 6 months.
