  • Old-Fashioned Rolled Oats: These whole grain oats make about half of the oatmeal bar crust. You’ll measure out one cup. 
  • White Whole Wheat Flour: One cup is all you need of this whole-grain ingredient.
  • Brown Sugar: A packed one-third cup of brown sugar helps provide some sweetness to the oatmeal bar crust. 
  • Grass-Fed Unsalted Butter: One stick of grass-fed melted butter brings the crust ingredients together. 
  • Strawberries: Two cups of diced strawberries (about 10 ounces) fill the center of these healthy dessert bars. You can use fresh or frozen strawberries. 
  • Lemon Juice: Half of a freshly squeezed lemon or about one tablespoon of bottled lemon juice provides the right amount of acidity to help lift the flavors. 
  • Sea Salt: You’ll add 1/4 teaspoon of sea salt.
  • Granulated White Sugar- You’ll add 2-3 teaspoons of white granulated sugar directly to the strawberries for additional sweetness.

Can You Use Frozen Strawberries In Oatmeal Bars?

Yes. I’ve had to do this on occasion when my grocery store is out of fresh strawberries or they aren’t in season. Frozen strawberries work well. And no need to completely thaw. 

You’ll simply dice them as you would fresh strawberries (you can slightly thaw in warm water or the microwave to make cutting easier).

Remove 3/4 cup of the prepared oat crumble mixture and set aside. You’ll use this later for the topping. In an 8×8 pan covered in parchment paper, add and press the remaining oat mixture into the pan.

Evenly layer two cups of diced strawberries on top of the oat crumble mixture in the pan. Drizzle the lemon juice evenly over the strawberries. Finally, lightly cover the strawberries in two to three teaspoons of granulated sugar.

Finally, you’ll add the remaining 3/4 cup of the oat crumble mixture to the top of the strawberries and using a spatula or fork, evenly spread around.  

oatmeal bar topping


In a preheated 375° oven, you’ll bake the oatmeal bars for 35-40 minutes until the top is lightly golden and smells toasty.

Now time to cool. Even though you’ll be tempted to dig in right away, it’s important to give these bars ample time to cool. This will give the bars a chance to gel together. Once cooled, cut and serve by themselves or with a side of frozen yogurt.

How To Store Oatmeal Bars

You can store oatmeal bars in the refrigerator for up to 5 days when properly covered.

You can also freeze these oatmeal bars. Be sure to let them cool completely. Wrap them tightly in plastic wrap and place them in an airtight container or bag in the freezer. They’ll keep for about three months. You can thaw them in the fridge.
