What you need
This chocolate oatmeal bar recipe features some of the basics already in your pantry. Let’s discuss just a few of the key ingredients:
Ingredients
This is a short overview of the ingredients I used and why I chose them. The full recipe can be found at the bottom of the post!
- Flour & oats: All-purpose flour works best for these bars. You must use quick-cooking oats because they prevent the bars from becoming too dense and chewy.
- Leavening: Baking powder and baking soda act as leavening agents in this recipe.
- Sugar & salt: The salt in the recipe helps balance out the sweetness from the two types of sugar – granulated and brown sugar.
- Chocolate: Bars of baking chocolate work best in this recipe and give it a smooth texture.
- Butter: This fat gives the recipe richness and flavor.
- Eggs: These add stability to the filling in the bars.
Equipment
This is a list of tools I used to make the chocolate oatmeal bars recipe.
- Baking pan: A 9×9-inch pan is perfect for these bars.
- Whisk & spatula: You’ll need a whisk and spatula to properly combine the ingredients in this recipe.
How to make chocolate oatmeal bars
1. Make the oatmeal base & topping
Combine dry ingredients with butter to create the base and topping. Bake the base and let cool for later.
- Preheat oven to 325°F. Line pan with parchment paper and cooking spray.
- Combine flour, oats, both sugars, baking powder, baking soda and salt with a whisk.
- Stir in melted butter to this mix.
- Save one cup of the mix to use as the topping.
- Press the rest into the pan.
- Bake for 8 minutes until light golden brown. Set aside to cool.
2. Make the filling
Mix dry ingredients, and then, combine with melted chocolate and eggs to create the filling.
- In a small bowl, combine the flour, sugar and salt with a whisk.
- Put the chocolate and butter in a heat-proof bowl set over a pot of barely simmering water. Use a silicone spatula to stir the mix until completely melted. Remove from heat.
- Whisk eggs into this chocolate mix one at a time.
- Stir in flour mixture until combined. The filling will look thick.
3. Layer and bake
You’ll place the filling on top of the cooled crust to build the chocolate oatmeal bars. Then, bake to finish.
- Pour chocolate mixture onto cooled crust from earlier. Sprinkle the remaining oat mixture onto the filling.
- Bake for 30 to 35 minutes. Edges should be set and lightly browned.
- Cool in the pan or on wire rack for 1 hour.
- Remove from pan and cut into squares.
Jen’s Best tips
- Only have old-fashioned rolled oats on hand? Pulse the rolled oats in your food processor to help break them down for use in the recipe.
- Avoid using chocolate chips in this recipe. They don’t melt as smoothly as bars of baking chocolate.
- For extra neat slices, refrigerate the bars for 2 hours before cutting.
Storing & Freezing
To store: Put the chocolate oatmeal bars in an airtight container in the fridge for up to 3 days.
To Freeze: These are perfect for making ahead because they freeze really well.
Completely cool the chocolate oat bars, and then, slice and individually wrap them in plastic wrap.
Place the wrapped bars in a sturdy container with an airtight lid and freeze them for no more than 3 months.
To use them, thaw overnight in the fridge. You can eat them cold or set them out to reach room temperature.

Notes
- Oats: quick-cooking oats are required. Old-fashioned rolled oats will leave the bars extra dense and chewy. If you don’t have quick-cooking oats, you can pulse rolled oats in a food processor to break them down some.
- Chocolate: Use bars of baking chocolate for best results. Chocolate chips don’t melt as smoothly.
- The bars will stay fresh in an airtight container in the refrigerator for up to 3 days.
- The bars also freeze well. Cool them completely the slice and wrap them individually in plastic wrap. Place the wrapped bars in a sturdy container with an airtight lid and freeze them for up to 3 months.
- Thaw them in the refrigerator overnight when you are ready to serve them. You can eat them cold or set them out to come to room temperature.
