Ingredients You’ll Need

These ingredients are wonderfully straightforward, but each one plays a vital role in crafting the perfect Peanut Butter Oatmeal Bars Recipe. From the rolled oats adding that signature chewiness to the golden sweetness of maple syrup, they all combine to create a balanced, satisfying flavor and texture.

• 1 cup (150 g) all-purpose/plain flour: Provides structure to hold the bars together.
• 1 cup (80 g) old-fashioned rolled oats: Adds hearty texture and whole grain goodness.
• 1/2 tsp sea salt: Enhances and balances all the flavors.
• 1/2 tsp baking/bicarb soda: Helps give a slight lift to the bars, keeping them from being too dense.
• 1/2 cup (125 g) butter, melted: Brings rich creaminess and binds ingredients beautifully.
• 1/3 cup (70 g) brown sugar: Imparts a deep, molasses-like sweetness that complements peanut butter perfectly.
• 2 tsp vanilla extract: Adds warmth and aromatic depth to the mix.
• 1 cup peanut butter (I use crunchy): The star flavor, giving both taste and texture with those delightful nutty bits.
• 2 tbsp maple syrup: Natural sweetness that balances the peanut butter’s savoriness.

How to Make Peanut Butter Oatmeal Bars Recipe

Step 1: Prepare Your Oven and Baking Dish

Start by preheating your oven to 175 degrees Celsius (350 Fahrenheit). Line an 8 by 8-inch (20 x 20 cm) baking dish with non-stick baking paper, making sure there’s some overhang to help you lift the bars out easily once baked.

Step 2: Mix Your Dry Ingredients

In a medium bowl, combine the all-purpose flour, rolled oats, sea salt, and baking soda. Stir them together well so every bite benefits from an even distribution of these essential dry ingredients.

Step 3: Combine Wet Ingredients

Melt the butter gently, then pour it into a separate bowl with the brown sugar and vanilla extract. Mix until the sugar begins to dissolve and everything is well incorporated. This wet mixture will add richness and sweetness to your bars.

Step 4: Bring the Mixtures Together

Pour the wet ingredients into the bowl with your dry mix and stir thoroughly. It should come together into a thick, slightly sticky batter that’s easy to press into shape.

Step 5: Press the Base

Reserve about one-quarter of the mixture for later. Firmly press the remaining three-quarters into the bottom of your prepared tin to form an even layer. This will be the golden, chewy foundation of your bars. Pop it into the oven and bake for 10 minutes until it’s just starting to set.

Step 6: Prepare the Peanut Butter Layer

While the base is baking, mix the peanut butter with maple syrup. If your peanut butter feels too stiff, warming it slightly in the microwave for a few seconds makes spreading much easier and ensures a smooth layer.

Step 7: Assemble the Bars

Remove the baking dish from the oven carefully. Immediately spread the peanut butter and maple syrup mixture over your warm base layer, creating a creamy, decadent middle layer. Then crumble the reserved dough over the top, sprinkling it evenly for a rustic, textured finish.

Step 8: Bake to Perfection

Return the dish to the oven and bake for another 10 minutes, or until the topping is set and turns a lovely light golden brown. The bars will smell heavenly at this stage, just waiting to be cooled down.

Step 9: Cool and Chill

Once out of the oven, allow the bars to cool at room temperature for about 30 minutes. Then refrigerate them for an additional 30 minutes to fully set the layers. This cooling step helps everything firm up so your bars hold their shape when sliced.

Step 10: Slice and Enjoy

With the bars completely chilled, lift them from the tin using the baking paper overhang and cut into squares. Now you have delicious, chewy, peanut buttery treats ready to be enjoyed or shared!

How to Serve Peanut Butter Oatmeal Bars Recipe

Garnishes

For a little extra flair, sprinkle chopped roasted peanuts or a drizzle of melted chocolate over the bars before serving. A light dusting of powdered sugar can also add a delicate, sweet touch that makes these bars feel special.

Side Dishes

These bars pair beautifully with a glass of cold milk or a warm cup of coffee or tea. For a more indulgent snack, try serving alongside a scoop of vanilla ice cream or a dollop of whipped cream to balance their chewy texture with creamy softness.

Creative Ways to Present

Cut the bars into bite-sized squares and thread them on skewers with fresh berries for a fun party platter. Alternatively, sandwich a layer of jam or Nutella between two bars for a decadent twist that’s sure to wow your friends and family.

Make Ahead and Storage

Storing Leftovers

Your Peanut Butter Oatmeal Bars Recipe leftovers keep beautifully in an airtight container in the fridge for up to one week. This makes them a perfect make-ahead snack, ready to be grabbed whenever a sweet craving hits.

Freezing

For longer storage, freeze the bars wrapped tightly in plastic wrap and then placed in a freezer-safe container or bag. They can be frozen for up to 2 months without losing flavor or texture, making them great for batch preparation.

Reheating

If you prefer your bars slightly warm, pop them in the microwave for 15-20 seconds or warm them up in a low oven. Just be careful not to overheat, or they may become too soft and sticky to handle easily.

FAQs

Can I use smooth peanut butter instead of crunchy?

Absolutely! Smooth peanut butter works just as well, giving a creamier texture without the crunchy bits. The bars will still be deliciously nutty and satisfying.

Is it possible to make these bars gluten-free?

Yes! Substitute the all-purpose flour with a gluten-free flour blend, and double-check that your oats are certified gluten-free to keep the bars safe for gluten-sensitive diets.

Can I substitute maple syrup with honey or another sweetener?

Honey works well as a replacement for maple syrup, offering a similar natural sweetness. Just keep in mind that honey’s flavor is more floral, which might slightly change the taste.

How long do these bars last at room temperature?

It’s best to keep them refrigerated, but if left at room temperature, they should stay fresh for up to 2 days, especially if stored in a covered container to prevent drying out.

Can I add mix-ins like chocolate chips or dried fruit?

Definitely! Mix-ins like chocolate chips, chopped nuts, or dried cranberries fold nicely into the batter and add exciting flavor bursts and texture. Add about 1/2 cup after mixing the wet and dry ingredients.
