Start your day off right with this delicious Apple Peanut Crunch! Juicy apples are baked under a sweet and wholesome, oat and peanut butter topping. Packed with nutrients and a little bit of protein, this is the perfect breakfast treat (but we won't tell anyone if you want to enjoy it with a scoop of ice cream)!

Everything's better with a little bit of crunch, don't you agree?
Apple Peanut Crunch is a delicious way to satisfy an apple dessert craving. Sliced, sweet apples fill a casserole dish and then are topped with an oat and peanut butter topping--reminiscent of a Nature's Valley granola bar.
Sugar is kept to a minimum in this treat; there's a little brown sugar and butter in the topping for a bit of a streusel flare, but that's essentially it!
This feel-good treat is perfect for breakfast or a weekend brunch, but it also makes a great after dinner dessert, just like Blueberry Buckle Coffee Cake and White Chocolate Cranberry Bread.
Why you'll love it
Fresh ingredients: Fresh apples are better for you and are packed full of vitamin C. This dessert is abundant in them, Feel good recipe: Unlike many other apple desserts, the apples in this crunch aren't coated in sugar, making this a healthier choice. Simple: This recipe uses pantry staples that you most likely already have on hand. |
Ingredients
- instant oats- for added nutrition and bulk in the topping
- all-purpose flour
- brown sugar- choose dark brown for a deeper molasses flavor
- salt
- peanut butter- I like to use crunchy peanut butter in this for a great texture
- butter- salted is best for this recipe
- fresh apples, peeled cored and sliced thin- I like Gala, Honeycrisp, or Fuji apples for this because they are sweeter
- fresh lemon juice- used as a preservative
- water
Instructions
For more detailed instructions, see the printable recipe card below
- In a large mixing bowl, combine oats, flour, brown sugar and salt.
- Add the peanut butter and the softened butter to the bowl. Use a pastry blender to combine these ingredients with the oat mixture. Then set this bowl aside.
- Next, prep the apples. Wash and peel the skins. Then use a paring knife to halve and core the apples. Slice apples into even-sized slices, aiming for ¼ inch thickness or less. Then place the sliced apples into a separate, large mixing bowl.
- Mix lemon juice and water together. Pour over apples and stir to coat.
- Then place apple slices in a lightly greased 8 x8 baking dish.
- Spoon peanut butter/oat mixture over apples.
- Bake uncovered at 375 degrees for 40 minutes or until apples are fork tender.
- Let stand 5-10 minutes before serving.

Helpful tips
- Try to keep the slices uniform so that the apples bake evenly. Aim for thin slices so that the fruit is fork-tender after it bakes.
