I first made these Chocolate Chip Cookie Dough Brownie Bombs on a rainy afternoon when I wanted something indulgent but easy. Think of them as a brownie with a surprise: soft, buttery, eggless cookie dough in the center and warm, fudgy brownie all around. They’re perfect for bake sales, weeknight dessert cravings, or whenever you want something impressive with minimal fuss.
What makes this recipe special
These bombs combine two universal comfort foods—cookie dough and brownies—into one portable, party-ready bite. Using boxed brownie mix keeps the base quick and reliable, while a simple, eggless cookie dough (butter, sugars, flour, chips) gives you that nostalgic dough center without raw egg safety concerns. The whole assembly is straightforward: layer, spoon, bake, and enjoy.
"A total crowd-pleaser—chewy brownie on the outside and pillowy cookie dough surprises from the middle. I doubled the batch for a party and they disappeared in under 20 minutes." — happy tester
Reasons to make this now:
- Fast: pantry staples plus a boxed mix means less time prepping and more time eating.

- Flexible: easy to customize with different chips or fillings.
- Great for gifting and parties: they look homemade and indulgent without complicated technique.
Step-by-step overview
This recipe is easy: make a quick, eggless cookie dough, prepare the brownie batter per box instructions, then assemble in a greased muffin tin by sandwiching a spoonful of cookie dough between two layers of brownie batter. Bake at 350°F for about 20–25 minutes until set. Let cool so the centers firm up a little before popping them out.

Gather these items
- 3/4 cup butter, softened
- 3/4 cup brown sugar (packed)
- 1/4 cup white granulated sugar
- 1 cup all-purpose flour (see safety note below)
- 1/2 teaspoon salt
- 1 cup chocolate chips (semisweet or mix types)
- 1 box brownie mix (your favorite brand)
- Eggs and oil as required by the brownie mix (follow box directions)
Notes and substitutions:
- Flour: If you plan to taste raw cookie dough, heat-treat the flour (see safety tips below). Alternatively use store-bought edible cookie dough or pasteurized oat flour for a different texture.
- Butter: You can use salted butter; reduce added salt by 1/4 tsp. For dairy-free, use a stick-style vegan butter and a dairy-free brownie mix.
- Chocolate chips: swap for chunks, white chocolate, or peanut butter chips.
- Brownie mix: a fudgy-style mix is best for a gooey contrast; cake-style will be firmer.
Directions to follow
- Preheat your oven to 350°F (175°C). Grease a standard 12-cup muffin tin or line with sturdy paper liners.
- Make the cookie dough: in a medium bowl, cream together the softened butter, brown sugar, and white sugar until smooth and slightly fluffy.
- Add flour and salt: gradually mix in the all-purpose flour and salt until just combined. Fold in the chocolate chips. (No eggs here—this makes the dough dense and scoopable.)
- Prepare the brownie batter according to the package instructions, using the eggs and oil called for on the box. Stir until smooth.
- Assemble: spoon about 1 to 2 tablespoons of brownie batter into each muffin cup to form a base layer. Add a spoonful (roughly 1 tablespoon) of cookie dough onto the brownie layer in each cup. Top each with additional brownie batter so the cookie dough is mostly covered. Leave a little room at the top for expansion.
- Bake: place the muffin tin in the oven and bake 20–25 minutes. Check by inserting a toothpick into the brownie (not straight through the cookie dough core); it should come out with moist crumbs but not wet batter. Smaller tins or higher heat may reduce the time—watch closely.
- Cool: let the bombs cool in the tin for at least 10–15 minutes so centers set. Transfer to a wire rack to finish cooling before serving or storing.
Yield: about 12 standard muffin-size brownie bombs (depends on how full you fill cups).
Best ways to enjoy it
- Serve warm with a scoop of vanilla ice cream and a drizzle of caramel or chocolate sauce for a decadent dessert.
- Plate two bombs with a dusting of powdered sugar and a few fresh berries for a pretty party tray.
- For a casual treat, wrap one in parchment and pack for snackable indulgence.
- Pair with coffee, milk, or a dessert wine—milk or cold brew coffee balances the sweetness nicely.
The best way to save extras
- Short-term storage: place cooled bombs in an airtight container. Refrigerate up to 4 days. Because these contain butter and brownie (eggs in the mix), refrigeration is safest.
- Freezing: freeze in a single layer on a sheet tray until firm, then transfer to a freezer-safe bag or container. Freeze up to 3 months. Thaw in the fridge overnight or reheat from frozen (see reheating below).
- Reheating: microwave 10–20 seconds for a warmed center, or bake at 325°F for 8–10 minutes from refrigerated to refresh texture. If reheating from frozen, add a few minutes at 325°F.
Food safety tips: don’t leave these at room temperature for more than 2 hours if they contain perishable fillings or were served outside in warm conditions.
Pro chef tips
- Chill the cookie dough 20–30 minutes before scooping if it’s too soft. Chilled dough holds shape better when assembling.
- Use an ice cream scoop or cookie scoop for consistent portions—this helps even baking.
- Don’t overfill the cups. Leave about 1/4 inch at the top so they don’t spill over.
- To test doneness, insert a toothpick into the brownie portion near the edge; a few moist crumbs are ideal. Overbaking dries the fudgy contrast you want.
- If you want a more gooey center, reduce bake time by a couple of minutes and allow longer cooling in the tin so centers set gently.
Creative twists
- Peanut butter surprise: press a small spoonful of peanut butter on top of the cookie dough before sealing with brownie batter.
- Salted caramel: add a dot of salted caramel sauce to the cookie dough center for a sweet-salty hit.
- Double-chocolate: use chocolate cookie dough (replace 1/4 cup flour with 2 tbsp cocoa powder) and chocolate chunks.
- Gluten-free: use a gluten-free all-purpose flour blend and a gluten-free brownie mix.
- Mini version: use a mini muffin tin and reduce bake time to 12–15 minutes for bite-sized bombs.
- No-box option: swap the boxed brownie with a reliable scratch brownie batter—just keep proportions similar for pan size.
Your questions answered
Q: Is the cookie dough safe to eat raw?
A: This recipe’s cookie dough contains no eggs, which removes one common raw-egg risk. However, raw flour can harbor bacteria. If you plan to eat raw dough often, heat-treat flour by spreading it on a baking sheet and baking at 350°F for 5 minutes or microwaving in 30-second bursts until the temperature reaches 165°F. Alternatively, use pasteurized or heat-treated flour or edible cookie dough products.
Q: How long do these keep, and can I freeze them?
A: Store cooled bombs in an airtight container in the fridge up to 4 days. For longer storage, freeze up to 3 months. Thaw overnight in the refrigerator, then warm gently before serving if you like them gooey.
Q: Can I make these in a mini muffin tin?
A: Yes. Reduce filling amounts and check bake time—mini versions usually take 12–15 minutes at 350°F. Keep an eye to avoid overbaking.
Q: What if I want a completely homemade version (no box)?
A: You can use any reliable brownie recipe. Choose a fudgy batter for the best texture contrast. Keep the same oven temperature and monitor baking time—the dense homemade batter might need a minute or two more.
Q: How many does this recipe make?
A: As written, it will fill a standard 12-cup muffin tin (about 12 brownie bombs). Exact yield depends on how generously you fill each cup.
