This no fuss Blueberry Peach CocoOat Crisp is a recipe we love having all summer long. Sweet, juicy peaches and fresh blueberries bake into a perfectly jammy filling, then get topped with a buttery oat crisp loaded with flaky coconut for the most irresistible golden crunch.
I love this recipe because it’s simple enough for a weeknight dessert but beautiful enough to serve when friends and family come over. Just toss the fruit together, sprinkle on the crisp, and let the oven do the work. The vanilla bean paste, cinnamon, and fresh lemon juice bring out the natural sweetness of the fruit, while chilling the crisp topping before baking creates those big buttery clusters everyone reaches for first.
Serve it warm with a scoop of vanilla ice cream, or homemade whipped cream, and you’ve got one of the best summer desserts you’ll make all season.
Why you’ll love this recipe!
What ingredients do I need?
- Peaches: Fresh peaches become sweet, tender, and jammy as they bake, creating the perfect fruit filling.
- Blueberries: Fresh blueberries add bursts of sweetness and beautiful color while complementing the peaches.
- Dark Brown Sugar: Adds caramel notes and enhances the natural sweetness of the fruit.
- Vanilla Bean Paste: Provides deep vanilla flavor and beautiful flecks of vanilla throughout the filling.
- Fresh Lemon Juice: Brightens the fruit and balances the sweetness.
- Flour and Cornstarch: Work together to thicken the juices into a luscious filling.
- Old-Fashioned Oats: Create hearty texture and crispy clusters.
- Unsweetened Coconut Flakes: Lightly toast while baking, adding subtle coconut flavor and extra crunch.
- Unsalted Butter: Creates rich, buttery topping with crisp golden edges.
- Cinnamon: Adds warmth and enhances both the peaches and blueberries.
Recipe Variations
- Nutty Version: Add chopped pecans or walnuts to the topping.
- Change the Berry: Stir in raspberries or blackberries with the peaches
- Cherry Version: Swap the blueberries for cherries during cherry season.
- Individual Portions: Make individual crisps in ramekins for entertaining guests. Adjust bake time accordingly.
Pro Tips
- Use ripe, but not overly soft peaches. The peaches should give slightly when gently squeezed. Overripe peaches can become too soft during baking.
- Peel the peaches for the best texture. While you can leave the skins on, peeling creates a smoother, more cohesive filling.
- Chill the crisp topping before baking. This helps the butter firm back up, creating larger, crispier clusters instead of a sandy topping.
- Don’t skip the cornstarch. It thickens the fruit juices and prevents a watery filling.
- Adjust the cornstarch for extra juicy peaches. If your peaches release a lot of juice, add an additional teaspoon.
- Bake until bubbling. The filling should be actively bubbling around the edges. This ensures the cornstarch has fully activated.
- Let the dessert rest before serving. Allow it to cool for 10–15 minutes before serving so the filling can thicken slightly.
- Serve warm and add a scoop of vanilla ice cream. Ice cream melting into the warm crisp is hard to beat.
Can I Substitute?
Yes! Like always though, any substitutions made to the recipe can result in a change in texture and/or flavor.
- Fresh peaches: Frozen peaches may be substituted. Thaw and drain excess liquid before using. You can also use fresh nectarines in place of the peaches.
- Blueberries: Fresh or frozen blueberries both work well. If using frozen, there’s no need to thaw first.
- Vanilla Bean Paste: Substitute with pure vanilla extract.
- Lemon Juice: Orange juice creates a slightly sweeter citrus flavor.
- Unsweetened Coconut: Omit if preferred and replace with additional old-fashioned oats.
- Dark Brown Sugar: Light brown sugar may be substituted for dark brown sugar.
- Unsalted Butter: Salted butter may be used; simply reduce the added kosher salt slightly.
Dietary Substitutions
- Gluten-Free: Use your favorite 1:1 gluten-free flour blend and certified gluten-free oats.
- Nut-Free: This recipe is naturally nut-free. Always verify ingredient labels if needed.
- Dairy-Free: Substitute the butter with a high-quality plant-based butter.
- Vegan: Use plant-based butter and serve with dairy-free vanilla ice cream.
Leftovers and Storage
- Refrigerator: Store covered in the refrigerator for up to 5 days.
- Freezer: Freeze baked or unbaked crisp for up to 3 months. Thaw overnight in the refrigerator before baking or reheating.
- Reheating: Warm individual servings in the microwave for 30–45 seconds, or reheat larger portions in a 325°F oven until warmed through.
- Best Tip: If reheating in the oven, loosely tent the crisp with foil after the topping has browned to prevent over-browning while the filling heats through.
But, I Still Have A Few Questions…
Do I have to peel the peaches?
I recommend peeling the peaches for the best texture, especially if you’re serving this to guests. The skins can become a little chewy after baking. If you don’t mind the texture or you’re short on time, you can absolutely leave the skins on.
How do I know if my peaches are ripe enough?
Look for peaches that give slightly when gently squeezed and have a sweet fragrance. They should be ripe but still firm enough to hold their shape while baking. Overripe peaches tend to release more liquid and can become mushy.
Can I use frozen peaches?
Yes! Frozen peaches work well in this recipe. Thaw them first and drain away any excess liquid before mixing the filling. If the peaches seem especially juicy, add an extra teaspoon of cornstarch to help thicken the filling.
Can I use frozen blueberries?
Absolutely. Frozen blueberries can be added directly from the freezer without thawing. They may release a little more juice while baking, but the flour and cornstarch will help create a thick, jammy filling.
Why is my topping not crispy?
For the best buttery crisp, be sure to chill the topping before baking. This helps the butter firm back up so it bakes into crisp, golden clusters. Also, bake until the topping is deeply golden and the filling is bubbling around the edges.
Why is my fruit filling runny?
Extra juicy peaches can release more liquid than expected. If your peaches are very ripe, add an additional teaspoon of cornstarch before baking. It’s also important to let the crisp rest for 10–15 minutes after it comes out of the oven so the filling has time to thicken.
Can I make this ahead of time?
Yes! You can prepare the crisp topping up to two days ahead and store it covered in the refrigerator. You can also assemble the entire dessert several hours before baking and refrigerate it until you’re ready to pop it into the oven.
Can I freeze this crisp?
Yes. You can freeze it either before or after baking. Wrap it tightly and freeze for up to 3 months. If baking from frozen, simply add about 10–15 minutes to the baking time and cover loosely with foil if the topping begins to brown too quickly.
Can I leave out the coconut?
Definitely. If coconut isn’t your favorite, simply replace it with an equal amount of old-fashioned oats. You’ll still end up with a delicious, buttery topping.
Can I add nuts to the topping?
Absolutely, I love that! Chopped pecans, walnuts, or sliced almonds all pair beautifully with peaches and blueberries. Stir about ½ cup into the topping before baking for extra crunch.
What should I serve with Blueberry Peach CocoOat Crisp?
This dessert is delicious on its own, but it’s even better served warm with a scoop of vanilla ice cream. Fresh whipped cream is another classic option, or try serving it with lightly sweetened whipped mascarpone or a dollop of vanilla Greek yogurt for brunch.
Can I use other fruit?
Absolutely. This recipe is very versatile. Try swapping the blueberries for blackberries, raspberries, cherries, or even sliced nectarines. You can also use all peaches if you prefer a classic peach crisp.
How do I know when it’s finished baking?
The crisp is done when the topping is golden brown and the fruit filling is bubbling around the edges of the baking dish. Those bubbling juices are a good sign that the cornstarch has fully activated and the filling will set as it cools.
What baking dish did you use for this recipe?
I made this recipe in my favorite blueberry pie dish. I love it because it bakes evenly, looks beautiful enough to serve straight from the oven to the table. If you’re looking for a fun pie dish you’ll use all year long, this is the one I reach for most often. You can find the exact pie dish I used here. I get so many compliments on this one!
