If a cookie could high-five you, this one would — with a peanut-buttery, chocolate-smeared palm. I don’t mess around when snacks call for both nostalgia and immediate happiness, so I stuffed buttery peanut butter cookie dough with tiny Reese’s Peanut Butter Cups and created the most ridiculous little bite-sized joy bombs. These little cookies giggle when you press a warm mini Reese’s into the center: the chocolate softens, the peanut butter gets gooey, and the kitchen smells like a candy store on a lazy Saturday. They bake up with crackled tops, golden edges, and a soft, tender center that begs you not to shove the whole plate into your mouth at once (but you will, and so will I).

Why This Recipe is Awesome
These are tiny, buttery peanut butter cookies with a molten chocolate surprise — who doesn’t love that? They deliver a crunchy edge, a pillowy center, and a hit of candy-cup saltiness all in one bite. They take practically no time, use easy pantry staples, and taste like a warm hug from your snack drawer. It’s so foolproof even your oven can’t mess it up — unless you forget to preheat, then the oven may sulk a little.
Ingredients
For the Main Dish:
- 1 1/4 cups all-purpose flour
- 1 tsp baking soda
- 1/4 tsp salt
- 1/2 cup unsalted butter, softened (1 stick)
- 3/4 cup creamy peanut butter
- 1/2 cup granulated sugar
- 1/2 cup packed light brown sugar (about 4 oz)
- 1 large egg, room temperature
- 1 tsp vanilla extract
- 24 mini Reese’s Peanut Butter Cups (or about 1 cup chopped)
- Optional: flaky sea salt for sprinkling
For the Sauce / Garnish (if applicable):
- Optional drizzle: 2 tbsp melted chocolate or a dusting of powdered sugar
How I Make It
Step 1:
I heat the oven to 350°F and line a baking sheet with parchment paper so the bottoms don’t stick and clean-up stays easy. I whisk together the 1 1/4 cups flour, 1 tsp baking soda, and 1/4 tsp salt in a bowl — dry ingredients first so the dough stays consistent.
Step 2:
I cream the 1/2 cup unsalted butter, 3/4 cup creamy peanut butter, 1/2 cup granulated sugar, and 1/2 cup packed brown sugar in a mixing bowl until the mixture looks light and slightly fluffy. It smells like peanut-butter heaven. I add the egg and 1 tsp vanilla and beat until glossy, then fold in the dry mix. I stop mixing when I can’t see streaks of flour — overmixing makes cookies tough, and I want tender.
Step 3:
I scoop the dough into tablespoon-sized balls (I use a small cookie scoop) and place them about 2 inches apart on the tray. I slightly flatten each ball so the cookie bakes evenly. If you want the classic crisscross, press a fork lightly, but I skip that because the mini Reese’s press gives a prettier top. The dough smells warm, nutty, and so inviting at this stage.
Step 4:
I bake for 10–12 minutes until the edges turn golden and the tops show those classic little cracks. Listen for a gentle sizzle as the sugar caramelizes — that’s the sound of cookie magic. I immediately press an unwrapped mini Reese’s into the center of each hot cookie; the chocolate softens and melts a bit, creating that irresistible goo. If the cups are too tall, use chopped pieces instead.
Step 5:
I let the cookies cool on the sheet for about 5 minutes so they set, then move them to a rack to cool completely. I sprinkle a little flaky sea salt while the chocolate still warms to make the flavors pop. They look golden, smell nutty and sweet, and they taste dangerously better than store-bought versions.
Pro Tips
- Use room-temperature butter and egg so the batter emulsifies smoothly; cold butter gives uneven texture.
- If your dough spreads too much, chill it for 10–15 minutes — it helps the cookies stay puffy and hold their shape.
- Press the mini Reese’s in right out of the oven for a glossy, slightly melted finish; press too late and they’ll sit on top cold and firm.
- Swap in a silicone mat if you want crisper bottoms; parchment keeps them tender and easy to lift.
Common Mistakes to Avoid
- Skipping preheating: Classic rookie move. It changes texture and bake time.
- Overmixing: Leads to dense or chewy results. Mix until just combined.
- Guessing cook time: Always use visual cues or a timer, not just vibes.
- Overcrowding pans: Give your food some breathing room to crisp properly.
Alternatives & Substitutions
- Use crunchy peanut butter for extra texture — expect more chew and peanut pieces in every bite.
- Swap brown sugar for coconut sugar for a deeper caramel note (color and moisture change slightly).
- Gluten-free: use a 1:1 gluten-free flour blend; the texture stays similar but might brown faster, so watch the time.
- Dairy-free: use vegan butter and dairy-free mini peanut butter cups; the cookies stay rich but lose a touch of that buttery magic.
Variations & Tips
- Add 1/2 cup chocolate chips to the dough for double-choc peanut butter bites.
- Make them spicy-sweet by adding a pinch (1/8 tsp) cayenne or smoked paprika to the dough for adults-only heat.
- Turn them into bars: press dough into a 9×9 pan, top with chopped Reese’s, bake 18–22 minutes, and cut into squares.
- Stuff with a whole mini cup inside the center for a gooey molten core — chill the dough balls first so they don’t flatten too fast.
- Creative twist: swirl in 2 tbsp Nutella with the peanut butter for a hazelnut undertone.
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Prepare the dough, roll into balls, and refrigerate up to 48 hours or freeze for up to 3 months. Bake from chilled, adding 1–2 minutes to the bake time if necessary.
- Can I double the recipe?
- Sure thing. Use two baking sheets and rotate them halfway through baking so everything browns evenly. Keep the dough chilled in batches if it warms up.
- Can I substitute butter with oil?
- Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil and expect slightly denser, less structured cookies.
- How do I know it’s done?
- Look for golden edges and cracked tops. The center should still look soft but not wet. The cookies firm up as they cool, so don’t overbake for a tender middle.
- What if I don’t have ingredient X?
- No biggie. Use store-bought natural peanut butter if creamy isn’t available (expect a touch more oil). If you lack mini Reese’s, chop regular-size cups or use chocolate chips for a simpler version.
How I Like to Serve It
I serve these on a bright plate with a tall glass of cold milk or a steaming mug of coffee — the contrast makes each bite sing. They make a killer after-school treat, a crowd-pleasing holiday platter item, or an indulgent boss move for potlucks. In summer I pop them in a picnic box; in winter they warm my hands and my mood.
Notes
- Store in an airtight container at room temperature up to 3 days, or refrigerate up to a week. Reheat gently for 8–10 seconds in the microwave for that fresh-from-the-oven feel.
- If you freeze unbaked dough balls, bake from frozen adding an extra 2–3 minutes to the bake time.
