What You’ll Need

The spiced oat crumble will be your favorite part of this baked blueberry cobbler. Scroll to the recipe card at the bottom of the post for exact ingredient amounts.

For the Filling

  • Blueberries Feel free to use leftover blueberries that aren’t as round and plump anymore.
  • Cornstarch All-purpose flour and tapioca starch work too.
  • Maple syrup Agave syrup and raw honey are great swaps.
  • Lemon juice Reduce the amount by half if you use lime juice.
  • Cinnamon You can also use ground nutmeg.
  • Vanilla extract – Go for almond extract if that’s what you’ve got on hand.
  • Salt Kosher salt is best.

For the Crumble

  • Regular oats They must be old-fashioned because quick oats will make the crumble chewy and rubbery.
  • Gluten free baking flour All-purpose flour works too.
  • Pecans Chopped almonds, macadamias, and walnuts are great as well.
  • Maple syrup You can also use light brown sugar as a sweetener.
  • Cinnamon Feel free to use 1/4 teaspoon ground cardamom instead.
  • Salt – Skip it if you use salted butter.
  • Butter I prefer unsalted butter, but margarine works too.

Should I Use Fresh Or Frozen Blueberries?

Both fresh and frozen blueberries are fine for making this cobbler. If you use frozen, make sure they’re completely thawed and drained. If they’re not, they’ll release all the excess moisture into the baking dish and the crumble won’t become crispy.

How To Make Blueberry Cobbler

You’ll love that the filling and crumble only need to be mixed and then poured into the baking dish. Scroll to the bottom of the post for the full recipe card.

  • Prep the filling. Preheat the oven to 350F. Mix the blueberries, cornstarch, maple syrup, lemon juice, cinnamon, vanilla extract, and salt in a large bowl until well combined. Pour it into a cast-iron skillet. You can also use a baking dish.
  • Make the crumble. Use your hands to mix the oats, flour, pecans, maple syrup, cinnamon, salt, and butter in a separate bowl until course and crumbly. If you don’t like mixing with your hands, use a wooden spatula.
  • Bake it. Evenly sprinkle the crumble mixture over the blueberry filling in the baking dish. Pop it into the oven for 35-40 minutes.
  • Serve. Remove it from the oven and let it cool for 10 minutes. Serve and enjoy!

Tips & Variations

Spice up your baked blueberry cobbler with fresh peaches, ground cardamom, or leftover granola.

  • Make it a berry cobbler. Swap half of the blueberries for a berry mix if you want to add more natural sweetness and tartness to your cobbler.
  • Use leftovers. Mix any Coconut Blueberry Granola or Almond Joy Granola into the crumble for extra crunch. My Simple Gluten Free Granola works too.
  • More crunch. Stir 2-3 tablespoons chia seeds or flax seeds into the crumble mixture for more texture.
  • Add toppings. Sprinkle the cobbler with dried cranberries, shredded coconut, mini chocolate chips, or whipped cream.
  • More spices. Mix 1/4 teaspoon ground nutmeg and 1/4 teaspoon ground cardamom into the crumble ingredients for an extra warmly-spiced crumble.
  • Turn it into a peach-blueberry cobbler. Swap 1/4-1/2 of the blueberries in the filling for diced peaches (fresh or canned).

Serving Suggestions

This blueberry cobbler is an easy dessert option. Top it with vanilla ice cream, frozen yogurt, or my Espresso Chocolate Chip Ice Cream. You can also enjoy it with a glass of milk, a cup of tea, or your favorite coffee. Try it with my Iced Chai Tea Latte, Sweet Cream Iced Coffee, or Coconut Milk Thai Iced Coffee.

How To Store & Reheat Leftovers

Cover the baking dish with foil to reduce clean-up for storing and reheating.

  • Fridge: Place it away from strong-smelling foods like onions. It’ll keep for up to 4 days.
  • To reheat it: Microwave it in 15-second increments until warm. For larger portions, use the oven at 300F for 20-25 minutes.
