• Perfectly Portioned. No more fighting over the crispy edges! Everyone gets their own little cup with the ideal berry-to-topping ratio, making serving a breeze, whether it’s a casual family dinner or a more festive gathering.
• Incredibly Versatile. You can use virtually any combination of fresh or frozen berries you have on hand. A bag of frozen mixed berries works like a charm year-round, and you can even toss in some diced apple or peach if you’re feeling adventurous.
• Simple & Satisfying. This recipe doesn’t require any fancy techniques or equipment. It’s a humble, honest dessert that relies on the natural sweetness of the fruit and the cozy texture of oats. It’s the kind of baking that just feels good for the soul.

Ingredients & Tools

• For the Berry Filling:
• 500 g (about 4 cups) mixed berries (fresh or frozen)
• 2 tbsp maple syrup or honey
• 1 tbsp fresh lemon juice
• 1 tbsp cornstarch or arrowroot powder
• 1/2 tsp pure vanilla extract
• A pinch of fine sea salt
• For the Oatmeal Crisp Topping:
• 120 g (1 1/4 cups) old-fashioned rolled oats
• 60 g (1/2 cup) almond flour (or all-purpose flour)
• 60 g (1/4 cup) coconut oil or unsalted butter, softened
• 3 tbsp maple syrup
• 1/2 tsp ground cinnamon
• 1/4 tsp ground nutmeg (optional, but lovely)
• A generous pinch of salt

Tools: A standard 12-cup muffin tin, a large mixing bowl, a medium mixing bowl, a small bowl for mixing the filling, and a spoon or cookie scoop for filling the cups.

A little note on the berries—using a mix really gives you the best flavor. The tartness from raspberries or blackberries balances the sweetness of blueberries or strawberries beautifully. And don’t worry if you’re using frozen berries; there’s no need to thaw them first, which makes this recipe a true lifesaver.

Before You Start: Tips & Ingredient Notes

• Frozen vs. Fresh Berries. Both work wonderfully! Frozen berries will release more liquid as they bake, which is why the cornstarch is our best friend here. There’s no need to thaw them—just toss them straight from the freezer into the mix.
• The Role of the Cornstarch. This is our thickening agent, and it’s non-negotiable if you want a jammy filling instead of a soupy one. Tossing it with the berries before adding the liquid ingredients helps prevent clumps.
• Why Almond Flour? I love using almond flour in the topping because it adds a lovely nutty flavor and helps create a crumbly, tender texture. If you don’t have it, an equal amount of all-purpose flour works just fine.
• Softened Coconut Oil/Butter is Key. You want your fat to be soft but not melted. This allows you to mix it into the dry ingredients properly, creating those perfect little clumps that will turn golden and crisp in the oven.
• Don’t Skip the Salt. It might seem odd in a sweet recipe, but a pinch of salt in both the filling and the topping makes all the flavors pop and balances the sweetness perfectly.

How to Make Berry Oatmeal Crisp Cups

Serving Suggestions

Complementary Dishes

• A scoop of vanilla bean ice cream — The classic pairing for a reason. The cold, creamy ice cream melting into the warm, juicy berries is a textural dream come true.
• A dollop of Greek yogurt or whipped coconut cream — For a slightly lighter option that still adds a lovely creamy contrast and a tangy note that cuts through the sweetness.
• Alongside a morning cup of coffee — Let’s be real, these are basically baked oatmeal in a dessert disguise. They are absolutely acceptable for a special weekend breakfast.

Drinks

• A glass of cold milk or a warm chai latte — The simplicity of milk is a perfect match, while the spices in a chai latte echo the cinnamon in the crisp topping beautifully.
• A light-bodied red wine like Pinot Noir — If you’re serving these after a dinner party, a wine with red fruit notes will complement the berries without overpowering them.
• Sparkling water with a twist of lemon — The effervescence and citrus are incredibly refreshing and help cleanse the palate between bites.

Something Sweet

• A simple, buttery shortbread cookie — Sometimes more is more! The crumbly, buttery texture of shortbread pairs wonderfully with the soft fruit and oat crunch.
• A small square of dark chocolate — Enjoyed alongside the crisp, the bitterness of dark chocolate creates a fantastic flavor contrast that feels very sophisticated.
• A drizzle of extra maple syrup — For those who have a serious sweet tooth, a little extra drizzle right before serving adds a beautiful shine and a hit of caramel-like flavor.

Top Mistakes to Avoid

• Mistake: Using melted butter/oil. If your fat is liquid, it will coat the oats instead of forming clumps, resulting in a greasy, less crispy topping. Softened is the way to go.
• Mistake: Skipping the cornstarch. I’ve tried it, and you end up with a berry soup at the bottom of your cups. The cornstarch is essential for binding the juices released by the berries as they bake.
• Mistake: Overfilling the cups. While you can fill them nearly to the top, leave just a tiny bit of space. The berries will bubble up as they cook, and you don’t want a sticky mess all over your oven floor.
• Mistake: Not letting them cool. I know, the temptation is real. But if you try to remove them from the tin immediately, the filling will be too loose and they might fall apart. That 15-minute rest is crucial for structural integrity.

Expert Tips

• Tip: Add some nutty crunch. Toast the oats in a dry skillet for a few minutes before making the topping. This deepens their flavor immensely and gives the whole dessert a more complex, nutty aroma.
• Tip: Get creative with add-ins. Stir a handful of chopped pecans or walnuts into the oat topping for extra texture. A tablespoon of chia seeds mixed into the berry filling can also help with thickening and add a nutritional boost.
• Tip: Make them gluten-free. This recipe is naturally gluten-free if you use certified gluten-free oats and ensure your almond flour is gluten-free. It’s an easy swap that makes these accessible to almost everyone.
• Tip: For a super-crispy top. If you love an extra-crunchy topping, pop the assembled cups under the broiler for the last minute of baking. Watch them like a hawk though—they can go from golden to burnt in seconds!

FAQs

Can I make these ahead of time?
Absolutely! You have two great options. You can assemble the cups completely, cover the tin tightly with plastic wrap, and refrigerate them for up to 24 hours before baking. You might need to add a minute or two to the baking time since they’ll be going in cold. Alternatively, you can bake them, let them cool completely, and then store them in an airtight container in the fridge for 2-3 days. Reheat in a 300°F (150°C) oven for about 10 minutes to bring back the crispness.

Can I use all one type of berry?
Of course! While a mix is nice for complexity, using just blueberries or just raspberries is delicious. Just keep in mind that some berries are tarter than others. If you’re using only very tart berries like blackberries or cranberries, you might want to add an extra tablespoon of maple syrup to the filling to balance it out.

My filling is too runny. What happened?
This usually means the cornstarch didn’t get fully incorporated or the crisp cups needed a bit more time to bake. The filling continues to thicken as it cools, so if it seems a bit loose right out of the oven, give it more cooling time. If it’s still runny after cooling, next time try tossing the cornstarch with the berries even more thoroughly before adding the wet ingredients.

How do I store leftovers?
Once cooled, store any leftover crisp cups in an airtight container in the refrigerator for up to 3 days. The topping will soften a bit in the fridge, but you can easily re-crisp it by warming them in a toaster oven or a regular oven at 350°F (175°C) for 5-7 minutes. I don’t recommend freezing them after baking, as the berry texture can become a bit mushy upon thawing.

Can I make this as one big crisp instead?
You sure can! Simply spread the berry filling into an 8×8 inch baking dish, top with the oat mixture, and bake at the same temperature. It will likely need a few extra minutes in the oven—look for that same bubbling and golden-brown topping, which might take 35-40 minutes total.
