How to make mixed berry crisp
This mixed berry crisp (berry crumble) is so easy to make. Making this berry crisp takes just a few steps and some light assembling that anyone can do!
If you prefer to work with fresh berries, nothing changes with the recipe. Here is what it looks like.
Step 1: Mix frozen berries with vanilla, granulated sugar corn starch and lemon.
Step 2: Make your oat crumb topping by cutting butter into your flour, oats, brown sugar, salt and cinnamon.
Step 3: Add the berries to ramekins. You can also bake this up in a large 9 x 9 pan.
Step 4: Evenly distribute the oat crumble topping to the ramekins.
Making this for a crowd
This berry crisp recipe has been a lifesaver for me because it is the best dessert to make for a crowd since you can make large pans of it. This recipe will make enough to fill one 9x11 pan or four very large ramekins.
If you need to make this for even more people, you can just double or triple the recipe. I know from experience on this one as I use this for large events all the time! I have made multiple pans of this recipe and it is always eaten up.
For special occasions like the holidays, you can assemble all of the ingredients ahead of time. When ready, just bake it right before you are ready to eat it (see notes in the recipe below) .
Toppings
This mixed berry crisp is totally fine all on its own right out of the oven but it never hurts to add a topping. My favorite toppings to add to this crisp are:
- Vanilla Ice cream (especially when the crisps are still hot). Ice cream melting over a delicious crisp oat crumble topping is total heaven to me.
- Whipped cream. For this one I give the crisp a few minutes to cool down then add it.
- Powdered sugar. Because everything is prettier and tastier with powdered sugar.
Faqs
You can leave the berry crisp out for a bit but it is a good idea to refrigerate it covered if you have leftovers.
Berry crisps are great for make ahead desserts. You can make it ahead of time fully baked or fully assembled. If you decide to fully bake it ahead of time, just place aluminum foil over the top and re-heat in the oven on low heat until warmed through.
