Step-by-step instructions
- Preheat the oven: Set your oven to 350°F (175°C) and grease a baking pan.
- Mix dry ingredients: In a mixing bowl, combine the flour, rolled oats, brown sugar, baking powder, baking soda, and salt.
- Add wet ingredients: Stir in the melted butter, egg, and vanilla extract until you achieve a crumbly mixture.
- Create the base: Reserve half of this mixture to use later as a topping. Press the remaining half firmly into the bottom of the prepared baking pan.
- Layer with chocolate: Evenly sprinkle the chocolate chips over the crust, and then crumble the reserved mixture on top of them.
- Bake: Place in the oven and bake for 25-30 minutes or until the top is golden brown.
- Cool and cut: Once baked, allow the bars to cool completely before cutting them into squares.

Storage and reheating tips
To keep your chocolate chip muffin crumb bars fresh, store them in an airtight container at room temperature for up to 3 days. If you want to prolong their life, you can also freeze them for up to 3 months. Just make sure they are completely cooled before wrapping them in plastic wrap and placing them in a freezer-safe bag. When you’re ready to enjoy them again, let them thaw overnight in the refrigerator or warm them briefly in the oven.
Helpful cooking tips
For the best texture, make sure not to overmix the batter—mix just until combined. This will keep your bars tender and crumbly. If you want an extra crunch on top, consider adding chopped nuts or a sprinkle of coconut flakes to the reserved topping mixture. Additionally, if you prefer a deeper chocolate flavor, swapping half of the chocolate chips for dark chocolate chips is a fantastic option!
Creative twists
There are countless ways to add your personal touch to these chocolate chip muffin crumb bars. Incorporating spices like cinnamon or nutmeg can bring an entirely new flavor dimension. You could even swap out chocolate chips for other add-ins such as dried fruits, white chocolate, or peanut butter chips for a special twist. For a seasonal touch, try adding pumpkin puree during the fall or lemon zest in the summer for a refreshing citrus note.
