Step-by-Step Instructions

Ingredients

1 1/2 cups graham cracker crumbs (about 150 g)
1 cup creamy peanut butter (250 g)
1/2 cup unsalted butter, melted (113 g)
1 cup powdered sugar (about 120 g), sifted
1 1/2 cups semisweet chocolate chips (about 255 g)
1 tablespoon coconut oil or light vegetable oil (optional — helps the chocolate set glossy)
Optional ingredients and substitutions:
Use almond butter or sunflower seed butter to make nut-free (sunflower) or change the flavor (almond).
Swap graham crumbs for gluten-free cookie crumbs to make gluten-free bars.
Use dark chocolate chips for less sweetness or milk chocolate for a softer, sweeter topping.
Add 1/2 teaspoon flaky sea salt on top for contrast.

Method

Line an 8×8-inch (20 x 20 cm) baking pan with parchment, leaving an overhang for easy removal.
In a large bowl, combine graham cracker crumbs and powdered sugar; stir to blend.
Add melted butter and peanut butter to the dry mix. Stir until a uniform, dense dough forms — it should hold together when pressed. (Tip: If mixture feels too dry, add 1–2 teaspoons milk; too wet, add a tablespoon of crumbs.)
Press the mixture firmly and evenly into the prepared pan using a spatula or the bottom of a measuring cup to get a smooth, compact layer.
In a small saucepan over low heat (or in a microwave-safe bowl in 20-second bursts), melt the chocolate chips with coconut oil, stirring until smooth and glossy. Avoid overheating chocolate — stop when a few unmelted pieces remain and stir to finish melting.
Pour the melted chocolate evenly over the peanut butter layer, spreading with an offset spatula into an even layer.
Sprinkle flaky sea salt if using. Chill in the refrigerator at least 1 hour, until firm.
Once set, lift the slab out using the parchment overhang and slice into 12 bars. For cleaner cuts, warm the knife under hot water, dry it, then slice.

Practical tips

Press the base firmly to avoid crumbly bars.
Chill thoroughly — partially set chocolate will smear.
For neat edges, trim the slab’s perimeter with a warm knife before cutting bars.

Serve It Up

Classic: Serve chilled straight from the fridge — the temperature brings the best texture contrast between firm chocolate and soft center.
With coffee or iced tea: Pair a bar with a late-afternoon iced coffee or a minty iced tea for balance.
As a plated treat: Cut smaller squares and dust with cocoa powder or powdered sugar for a dessert platter.
Kid-friendly snack packs: Wrap bars individually in parchment or parchment-lined lunchbox sections.
Refreshing pairing idea: Offer a pitcher of infused water alongside the bars for a cooling counterpoint — try my favorite aesthetic water infusion ideas here: aesthetic water infusion.

Shelf Life & Storage

Room temperature: Not recommended for long in hot weather — up to 1 day in a cool, dry place (below 70°F / 21°C).
Refrigeration: Store in an airtight container for up to 7 days. Keep chilled until serving for the best texture.
Freezer: Freeze layered bars (cut or whole slab) in an airtight, freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before serving.

Chef’s Advice

Texture balance: The best bars have a compact, slightly firm base and a glossy, set chocolate top. Press the base firmly and chill long enough.
Chocolate quality matters: Use a decent semisweet chocolate (around 55–65% cacao) for flavor and a good sheen when combined with a tablespoon of oil.
Avoid grainy chocolate: Melt gently and avoid water contact — a tiny bit of moisture can seize chocolate.
Salt contrast: A light sprinkle of flaky sea salt on top brightens the flavor, cutting through sweetness.
Make-ahead friendly: Bars can be made 2–3 days ahead and stored in the fridge; for parties, slice right before serving for tidy edges.

Fun Flavor Ideas

Chocolate-Banana Swirl: Mix 1/2 cup mashed ripe banana into the peanut base (reduce powdered sugar to 3/4 cup) and top with dark chocolate for a banana-chocolate twist.
Coconut-Peanut Bars (Vegan option): Use coconut oil in place of butter and a refined coconut sugar powdered alternative; swap regular chocolate for vegan dark chocolate.
Pretzel Crunch: Fold 1 cup crushed pretzels into the peanut layer for salty crunch; sprinkle additional pretzel pieces on top.
Espresso Boost: Stir 1 teaspoon instant espresso powder into the melted chocolate for a coffee-kissed profile.
Nut-Free Sunbutter Bars: Replace peanut butter with sunflower seed butter and ensure all other ingredients are nut-free.

Recipe Q&A
Q: Can I use crunchy peanut butter?
A: Yes — it adds texture. Expect a slightly more crumbly base.

Q: My chocolate seized while melting. What can I do?
A: If seized, add a tablespoon of warm cream (or oil) and stir gently to loosen. For water-seized chocolate, start fresh if it’s too grainy.

Q: How do I make these lower in sugar?
A: Reduce powdered sugar to 3/4 cup and use a higher-percentage dark chocolate for the topping to lower overall sweetness. Keep in mind texture will change slightly.

Q: Can I double the recipe for a larger crowd?
A: Absolutely. Use a 9×13-inch pan for a doubled batch and adjust chilling time accordingly.
