Ingredients

1 cup butter, softened
1 1/2 cups packed brown sugar
2 cups oats
2 cups flour
1 teaspoon baking soda
1 (8 ounce) package semisweet chocolate (8 squares)
3/4 cup creamy peanut butter

Equipment Needed

9×13 inch baking dish
Mixing bowl
Measuring cups and spoons
Medium saucepan
Rubber spatula or wooden spoon

Instructions

Begin by preheating your oven to 350°F (175°C). Ensuring your oven is properly preheated is crucial for even baking and a perfectly golden-brown crust.
Prepare your 9×13 inch baking dish by greasing it thoroughly. This will prevent the bars from sticking and make them easier to remove after baking. You can use butter, shortening, or cooking spray.
In a large mixing bowl, cream together the softened butter and packed brown sugar. Use an electric mixer or a sturdy spoon to blend until the mixture is light and fluffy. This step incorporates air into the dough, resulting in a tender crumble.
In a separate bowl, sift together the flour and baking soda. Sifting helps to remove any lumps and ensures that the baking soda is evenly distributed throughout the flour, leading to a more consistent rise.
Gradually stir the flour mixture into the creamed butter and sugar. Mix until just combined, then stir in the oats. The mixture will be crumbly, which is exactly what you want for a crumble bar.
Press approximately 3 cups of the oat mixture firmly into the bottom of the prepared baking dish. This forms the base of your crumble bars. Use your fingers or the back of a spoon to create an even layer.
In a medium saucepan over low heat, melt the semisweet chocolate. Stir frequently to prevent burning. If you prefer, you can melt the chocolate in the microwave in 30-second intervals, stirring in between each interval.
Once the chocolate is completely melted and smooth, stir in the creamy peanut butter. Continue stirring until the peanut butter is fully incorporated and the mixture is glossy.
Carefully spread the chocolate-peanut butter mixture evenly over the pressed oat crust. Use a spatula to ensure a smooth and even layer.
Sprinkle the remaining oat mixture (the crumble) evenly over the top of the chocolate-peanut butter layer. Gently press the crumbs into the chocolate layer to help them adhere.
Bake in the preheated oven for 22-25 minutes, or until the edges are golden brown and the crumble topping is lightly browned. Keep a close eye on the bars during the last few minutes of baking to prevent burning.
Once baked, remove from the oven and let cool completely in the pan before cutting into bars. This allows the bars to set properly and makes them easier to slice.

Expert Tips & Tricks

For a richer flavor, use dark chocolate instead of semisweet.
To prevent the chocolate from burning while melting, add a tablespoon of butter or shortening to the saucepan.
If you find that the crumble topping is browning too quickly, tent the baking dish with aluminum foil during the last few minutes of baking.
For cleaner cuts, chill the bars in the refrigerator for at least 30 minutes before slicing. Use a sharp knife and wipe it clean between each cut.
If your peanut butter is very thick, microwave it for 15-20 seconds to make it easier to stir into the melted chocolate.
Make ahead: The dry ingredients can be mixed ahead of time and stored in an airtight container. The baked bars can also be made ahead of time and stored in the refrigerator or freezer.

Serving & Storage Suggestions

These Peanut Butter & Chocolate Crumble Bars are delicious served at room temperature or slightly chilled.

Variations & Substitutions

Gluten-Free: Substitute the all-purpose flour with a gluten-free all-purpose flour blend. Ensure the oats are certified gluten-free as well.
Vegan: Replace the butter with a vegan butter substitute. Check the chocolate to ensure it is dairy-free (many dark chocolates are).
Different Nut Butters: Experiment with almond butter, cashew butter, or sunflower seed butter instead of peanut butter.
Add-Ins: Mix in chopped nuts (like peanuts, walnuts, or pecans) into the crumble topping or the chocolate-peanut butter layer for added texture and flavor.
Chocolate Chips: Sprinkle chocolate chips on top of the chocolate-peanut butter layer before adding the crumble topping.
Salted Caramel: Drizzle salted caramel sauce over the baked bars for an extra touch of indulgence.

FAQs (Frequently Asked Questions)

Q: Can I use quick oats instead of rolled oats?
A: While you can, rolled oats provide a better texture to the crumble. Quick oats will result in a finer, less chewy crumble.

Q: How do I prevent the chocolate-peanut butter layer from being too hard when cooled?
A: Avoid overcooking the chocolate-peanut butter mixture while melting. Stir constantly and remove from heat as soon as the chocolate is melted and smooth.

Q: Can I use a smaller baking dish?
A: Yes, but you’ll need to adjust the baking time. A smaller dish will result in thicker bars, so you may need to increase the baking time by a few minutes. Keep a close eye on them to prevent burning.

Q: My crumble topping is too dry. What can I do?
A: Add a tablespoon or two of melted butter to the crumble mixture and mix until moistened.

Q: How long do these bars last?
A: They will stay fresh for up to 3 days at room temperature, a week in the refrigerator, or 2 months in the freezer.
