Jamie Oliver No Bake Chocolate Oat Bars

These Jamie Oliver No Bake Chocolate Oat Bars are exactly the kind of sweet treat I crave when I want something rich, chewy, and comforting—without turning on the oven. With layers of buttery oats, melty chocolate, and creamy peanut butter, they strike that perfect balance of indulgent and wholesome. I whipped up a batch one weekend and was amazed at how fast they disappeared! (inspired by Jamie Oliver)

Ingredients Needed

For the Oat Layer:

• 1 cup (227 g) butter
• 1/2 cup (100 g) brown sugar, packed
• 1 tsp vanilla extract
• 3 cups (270 g) quick-cooking oats

For the Chocolate Layer:

• 1 cup (175 g) semisweet chocolate chips
• 1/2 cup (125 g) creamy peanut butter

For the Topping:

• Additional chocolate chips for drizzle

How To Make Jamie Oliver No Bake Chocolate Oat Bars

Prep the Pan:
First, grease a 9×9 inch (23×23 cm) pan—I used a touch of butter, but parchment paper also works great for easy removal.

Cook the Oat Base:
In a medium saucepan, melt the butter over medium heat. Stir in the brown sugar and vanilla extract, letting it all melt together into a fragrant mixture. Add the oats and continue cooking on low heat for 2–3 minutes, stirring constantly so everything gets toasty and combined.

Create the First Layer:
Scoop half of the oat mixture into your prepared pan and press it down firmly using a spatula or the back of a spoon. You want a nice solid base here. Set aside the rest of the oats for the top layer.

Make the Chocolate Filling:
In a separate saucepan, gently melt the semisweet chocolate chips and creamy peanut butter over low heat. Stir until smooth and glossy—resist the urge to rush this part, slow and low gives the silkiest texture.

Assemble the Bars:
Pour the chocolate mixture over the oat base, spreading it out evenly. Then crumble the remaining oat mixture over the top and press down lightly to create a nice rustic finish.

Final Touch:
Melt a few more chocolate chips and drizzle over the top—this not only adds extra chocolatey goodness but also looks lovely once set.

Chill and Serve:
Cover the pan and refrigerate for at least 2–3 hours, or until the bars are firm. Before serving, let them sit at room temperature so they’re easier to slice into satisfying squares.

Why I Love This Recipe

I made these bars on a rainy Sunday afternoon and honestly, they were such a comforting treat. My kids couldn’t wait to dig in—and they even helped drizzle the chocolate on top! It’s the kind of recipe that feels nostalgic but clever, and it’s super flexible if you want to get creative.

Recipe Tips

• Use low heat: When melting butter or chocolate, always go slow to prevent scorching.
• Press firmly: A tightly packed oat layer gives you a sturdy base that won’t fall apart.
• Add-ins: Try mixing in chopped nuts, coconut flakes, or dried fruit for extra texture.
• Go dairy-free: Use vegan butter and chocolate chips to make this recipe vegan-friendly.
• Room temperature slicing: Let the bars warm slightly before cutting to avoid cracking the chocolate.

Let’s Answer a Few Questions! (FAQs)

Can I use old-fashioned oats instead of quick oats?
Totally! The bars will just be a bit chewier and heartier in texture.

Can I swap out the peanut butter?
Yes! Almond butter or sunflower seed butter both work great.

How long should they chill before cutting?
At least 2–3 hours in the fridge for best results.

Can I make them ahead of time?
Definitely. These bars are even better the next day after the flavors meld.

What’s the best way to get clean cuts?
Let the bars come to room temperature and use a sharp knife wiped clean between cuts.
