Don’t use natural, oily peanut butter. I learned this the hard way trying to make a “healthier” version. The oils separate and create a greasy film on the dip that is unappealing. The dip also never set properly. The stabilizers in conventional creamy peanut butter are crucial for giving this dip its stable, spreadable body. Save the natural stuff for your toast.
Avoid overmixing once you add the oats and candy. If you use your electric mixer for this step, you risk breaking the chocolate chips and crushing the M&M’s, which will bleed color into your dip and make it look muddy. Folding by hand is the only way to go. It takes a little arm power, but it preserves those beautiful pops of color and texture.
Finally, don’t skip the chilling time. I was impatient for my first test batch and served it right away. The flavor was one-dimensional, and the oats were distractingly chewy. The rest in the fridge is what transforms this from a mixed bowl of ingredients into a cohesive, flavor-packed dessert. It’s the step that makes it taste like a real monster cookie.
Serving Suggestions
I love serving this dip in a wide, shallow bowl surrounded by an array of dippers. My absolute favorite vehicle is crisp, tart apple slices (Granny Smiths are perfect). The cool, crisp apple against the rich, sweet dip is a match made in heaven. Graham cracker sticks, pretzel rods, and vanilla wafers are also fantastic for their sturdiness and complementary flavors.
For a next-level presentation, I create a “snack board” with this dip as the centerpiece. I’ll fill little bowls with extra M&M’s, chocolate chips, and even some crumbled cooked bacon for the adventurous. I arrange the dippers all around and let people build their perfect bite. It’s interactive, fun, and always a conversation starter.
This dip also makes an incredible filling or frosting. I’ve used it to sandwich between two mini chocolate chip cookies, or as a decadent frosting on brownie bites. For a birthday party, I once piped it onto the top of cupcakes in place of frosting, and it was a massive hit. Don’t be afraid to think beyond the bowl!
Variations & Customizations
For a fun twist, try using different candy mix-ins. I’ve swapped the mini M&M’s for Reese’s Pieces for an all-peanut butter experience, or used chopped-up peanut butter cups. During the holidays, I use red and green M&M’s for a festive touch. You could even add a handful of butterscotch chips for a butter-pecan-like flavor.
If you have nut allergies, you can make a “blondie” version. Replace the peanut butter with an additional 4 oz of softened cream cheese and a tablespoon of maple syrup or brown sugar for depth. You’ll still get a delicious, creamy dip, just with a different flavor profile. Add some toffee bits for extra crunch.
For a richer, deeper flavor, use half brown sugar and half powdered sugar. Replace 3/4 cup of the powdered sugar with an equal amount of packed light brown sugar, adding it with the butter and cream cheese. It gives the dip a caramel-like, molasses note that’s absolutely divine and even more reminiscent of baked cookie dough.
How to Store, Freeze & Reheat
Store any leftover dip in an airtight container in the refrigerator. It will keep perfectly for up to 5 days. The oats will continue to soften over time, but it remains delicious. I find it actually tastes best on day two! Just give it a quick stir before serving again.
You can freeze this dip for up to 2 months. Pack it into a freezer-safe container, press plastic wrap directly on the surface, and seal tightly. To thaw, transfer it to the refrigerator overnight. The texture may be slightly different upon thawing—a bit more crumbly—but a vigorous stir with a spoon will usually bring it back together. The M&M’s colors may run a little after freezing.
I do not recommend reheating this dip, as it’s meant to be served cool. However, if it’s too firm straight from the fridge, the “reheat” is simply letting it sit on the counter. If you’ve frozen it and it seems separated, you can let it come to room temperature and then beat it with a hand mixer for 30 seconds to re-emulsify the fats and bring back a creamy consistency.
