Make a scrumptious Instant Pot Blackberry Crisp using fresh or frozen berries! Topped with crisp buttery streusel, you’ll love this dessert!
Did you know you can use an Instant Pot to make an incredible blackberry crisp? Well… it’s TRUE! Even when it’s really hot outside (and I don’t want to heat up our kitchen), I can whip up an absolutely delicious fruit crisp in no time at all, using this handy dandy kitchen appliance!
This recipe is very versatile because, if necessary, you can use FROZEN blackberries as long as you don’t let them thaw! The good news is this means you can make Instant Pot Blackberry Crisp all year long, for a little taste of summer (even if it’s snowing outside!).
This is a very simple dessert recipe to prepare, and the end result is amazingly delicious! You’re going to love it! Here’s how to make Instant Pot Blackberry Crisp.

Before You Start – A Little Prep
Place a trivet in the inner pot, then add 1 cup of water. Set the Instant Pot aside while you make the fruit filling and streusel topping for the blackberry crisp.
You’ll need a 7″ round baking pan or a 7″ wide oven-safe glass bowl to make the blackberry crisp, so plan accordingly (they need to fit in a 6 qt. or 8-qt. Instant Pot). Generously spray the baking pan (or oven-safe bowl) you’re using with non-stick cooking spray on the bottom and sides.
Prepare The Blackberries And Streusel Topping
Place the blackberries in a medium-sized bowl. NOTE: If you’re using frozen blackberries, do not thaw them, but simply add them (still frozen) to the bowl.
Add granulated sugar and fresh lemon juice and gently stir until all the berries are covered with the sugar mixture.
Pour or spoon the berries into the greased 7″ baking pan and spread them out until the bottom of the baking pan (or bowl) is fully covered.
Now it’s time to make the streusel topping. In a separate bowl, stir oats, flour, brown sugar, cinnamon, nutmeg and salt together, until combined. Add melted butter and stir until the streusel becomes crumbly and can hold together when pinched.
Use your fingers to pinch off and distribute the streusel topping over the blackberry filling, making sure to evenly cover the blackberries.
Prep The Crisp For Cooking
Cover the pan with aluminum foil, crimping the edges firmly around the pan to ensure a secure seal. The foil helps prevent any water (condensation) from getting on the blackberry crisp while it cooks.
Carefully lower the covered baking pan onto the trivet (you may want to use the tip below if the baking dish you’re using doesn’t have a handle).
TIP: If needed, you can make a “sling” to help lower the baking pan into the inner pot. Do this by tearing off a long piece of foil (18″-20″), then fold it (lengthwise) into thirds so it’s thicker and stronger. Put the foil UNDER the pot with the long ends coming up both sides (shown below). Holding the ends of the foil, gently lower the pan onto the trivet. You can cook with the sling in place in the pot, then when it’s done cooking, it’s easy to lift the pan up and out of the hot inner pot.
Cook The Blackberry Crisp
Close the lid and lock it in place. Flip the steam release valve to SEALING. Select the MANUAL button (high pressure) and set the timer for 10 minutes.
It will take the Instant Pot about 7-9 minutes to reach full internal pressure before the cooking program (and timer) begins. The pressure gauge will pop up when it reaches full pressure. When the 10-minute cooking timer ends, the machine should alert you with a beeping sound.
When the cooking program ends, let the pressure release NATURALLY (do nothing) for 5 minutes, then flip the pressure knob to VENTING to release any remaining steam still inside. The pressure gauge should drop back down once all steam has been released, indicating it is safe for you to unlock and remove the lid.
Open the lid and carefully remove the baking pan out of the Instant Pot. At this point, in reality the blackberry crisp has finished cooking and can be cooled slightly then served. For BEST RESULTS, I highly recommend doing one quick final step before serving (see NOTE below).
NOTE: If you would like the streusel to be browner (and crispier), turn on your oven broiler while the Instant Pot is venting the steam. Once removed from the Instant Pot, place the baking pan on a rack about 4″ under the broiler in your oven. Keep an eye on it, of course, but after 2-3 minutes under the broiler, the topping should be more browned in color and even more crisp!
Serve And Enjoy Instant Pot Blackberry Crisp
Let the blackberry crisp cool for several minutes (it will firm up slightly), then scoop out warm portions into serving bowls. We usually get 5 small servings from this recipe.
Add a scoop of vanilla ice cream on top, if desired and serve this absolutely delicious blackberry crisp. The topping is crisp and buttery, and the blackberry filling tastes wonderful!
Here you go… I saved a big bite for you! You’re welcome! I’m confident you will love this delicious fruit cobbler as much as we do and will make it many times for family and friends.
I love using fresh-picked blackberries in the summertime, but it’s a wonderful option to enjoy this dessert year-round if you use frozen blackberries! Hooray!
I hope you have the opportunity to make this decadent Instant Pot Blackberry Crisp and hope you (and those you love) really enjoy it, too!
Thanks for stopping by, and I invite you to come back again soon for more family-friendly recipes. Take care, may God bless you, and have a wonderful day.

Make a scrumptious Instant Pot Blackberry Crisp using fresh or frozen berries! Topped with crisp buttery streusel, you'll love this dessert!
- 1 cup water For Instant Pot
- cooking spray (as needed) to grease 7" baking pan
- 12 ounces fresh or *frozen blackberries *If using frozen, DO NOT THAW
- 3 Tablespoons granulated sugar
- 1 teaspoon fresh lemon juice
- 1 cup old-fashioned oats uncooked
- ½ cup all-purpose flour
- ½ cup brown sugar light or dark½
- ½ teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- 1 pinch salt
- ½ cup butter MELTED (½ cup = 1 stick)
Place a trivet in the inner pot; add 1 cup of water. Spray a 7" baking pan generously with cooking spray on bottom/sides.
Place blackberries in a medium bowl. NOTE: If using frozen berries, do not thaw; put them (still frozen) in the bowl. Add granulated sugar and lemon juice. Gently stir until combined. Pour berries into baking pan; spread to cover the bottom.
In a separate bowl, stir oats, flour, brown sugar, cinnamon, nutmeg and salt together. Add melted butter; stir until streusel is crumbly and holds together when pinched. Spread streusel over the blackberries, covering the fruit.
Cover baking pan with foil, crimping the edges firmly around the pan to seal. Lower pan onto the trivet in the inner pot.
Put the lid on the Instant Pot; lock it in place. Turn the steam release valve to SEALING. Select the MANUAL button (high pressure); set the timer for 10 minutes. It will take 7-10 minutes to reach full pressure before cooking program/timer begins. When cooking program ends, the machine should beep.
Let the pressure release NATURALLY (do nothing) for 5 minutes, then flip pressure knob to VENTING to release all remaining steam. Pressure gauge will drop back down once all steam is gone, indicating it's safe to open the lid. Remove baking pan from the inner pot. The blackberry crisp is done cooking and can be cooled slightly then served. *I prefer to brown and "crisp up" the topping a bit more so I do 1 more step before serving. NOTE (optional): If you want streusel to be browner, turn on your oven broiler while the IP is venting. Once baking pan is removed from the IP, place it on a rack about 4" under the broiler. Keep an eye on it- after 1-2 minutes under broiler, streusel should be browner and crisper!
Let blackberry crisp cool for a few minutes (it will firm up as it cools), then scoop out warm portions into bowls (5 small servings). Add a scoop of vanilla ice cream (if desired) and serve. Enjoy!
