Why Make This?
And as a dietitian, I’m a fan of this recipe for a few reasons:
- Easy to make with minimal dishes!
- Both blueberries and peaches pack in lots of phytochemicals, plant compounds that are good for the body
- Less butter than traditional crisp toppings – there’s enough to add a little rich flavor without making it heavy.
- Uses maple syrup instead of refined sugar, and uses less added sugar total than most recipes (under a third a cup of maple syrup for the whole recipe).
- Great dessert for active women who need to fuel their fitness with healthy carbs!
Ingredients & Substitutions
Here’s a photo of all the ingredients you’ll need for the base:
And here’s what you’ll need for the topping:
Here are some selected ingredient and substitution notes:
- Flour – This is used to thicken the base as well as for the crisp topping. However, if you’d like to make this recipe gluten-free, you can substitute a gluten-free all-purpose blend instead. (If you’re gluten free, you’ll also want to use certified gluten-free oats).
- Cornstarch – Also added to help thicken the base. Additional flour can be substituted instead if you don’t have this on hand.
- Butter – This adds a richness and helps the topping crisp up. You can alternatively use coconut oil, dairy-free butter, or olive oil instead.
- Blueberries – Fresh or frozen work!
Instructions
You’ll find the full recipe amounts and instructions in the recipe card below, but here’s a helpful overview with photos and tips. This recipe is very simple to make!
Start by mixing all the base ingredients in a bowl: the peaches, blueberries, maple syrup, flour, cornstarch, vanilla, cinnamon, and salt.
Pour that into the skillet and wipe out the bowl (all about minimizing dishes for this recipe!).
In that bowl, mix together the dry topping ingredients: the oats, flour, cinnamon, and salt. Then add the maple syrup, butter, and vanilla. Mix well.
Pour the base ingredients in a cast iron skillet, then add the topping and spread it evenly over the base.
Bake that at 350 degrees F for about 25-30 minutes, then dig in and enjoy! Feel free to enjoy as-is or topped with vanilla ice cream, yogurt, or whipped cream.
Recipe FAQ
Here are some common questions that may come up as you’re preparing this recipe:
Yes. After storing it in the fridge, the topping can lose its crispness, but it will still taste great. You can always pop the skillet back in the oven briefly to get that crispness back if desired.
Store leftovers in an airtight container in the fridge for up to 4 days. Warm up a serving in the microwave when you’re ready to enjoy. Microwaved leftovers will not have the same “crunch” in the topping as the fresh-baked version, but will still taste great.
