    Peanut Butter Chocolate Muffins

    Jump to Recipe Print Recipe

    Are Peanut Butter Chocolate Muffins breakfast or dessert?? I'll leave that up to you... Just know that these jumbo muffins involve mini peanut butter cups and are absolutely delicious and addictive!

    (This recipe for Peanut Butter Chocolate Muffins was originally published in August 2013, but was updated with new photos and content in 2021).

    It's common knowledge that the only thing better than peanut butter is peanut butter when it's combined with chocolate. That's why Reese's Peanut Butter Cups are basically the best thing on planet Earth.

    We also all know that muffins are really just cupcakes in disguise. Especially if you stuff them with things like Reese's Peanut Butter Cups so that when you take a bite, you end up with a mouthful of chocolate.

    I'm not saying I did that. But I might have. OK, I did.

    I'm not sure whether to classify these peanut butter chocolate muffins as breakfast or dessert. Muffins are traditionally a breakfast food, but well, peanut butter cups.

    Let's just say there will be no judgement... No matter when you enjoy these muffins.

    How to Make Peanut Butter Chocolate Muffins

    These chocolate peanut butter muffins consist of three simple components:

    • Muffin Batter
    • Mini Peanut Butter Cups
    • Peanut Butter Streusel Topping

    The batter is simple to make. Simply, whisk together flour, baking powder, and salt in a medium bowl.

    In the bowl of a stand mixer or in a large bowl with a hand mixer, beat butter, peanut butter, and sugar together until light and fluffy, 3-4 minutes. Mix in eggs and milk until just combined.

    Gently fold dry ingredients into bowl with wet ingredients until just combined (take care not to over-mix).

    Now, fill lightly greased jumbo muffin tin about halfway with batter. And top each muffin with mini peanut butter cups. Press them gently into the batter.

    Then use remaining batter to continue filling each muffin cavity so they're about ¾ of the way full.

    Top with about 1 Tbsp peanut butter streusel topping.

    And bake at 375 degrees for 16-18 minutes, until toothpick inserted into muffins comes out only slightly sticky.

    Let muffins cool in tin for a few minutes before moving to racks to cool completely.

    How to Make Peanut Butter Streusel Topping

    Don't worry; the peanut butter streusel topping is the easiest thing in the world!

    Simply put melted butter, brown sugar, flour, peanut butter, and oats in a medium bowl.

    And mix together with a fork until you get a crumbly mixture.

    Try not to just eat it as is... Because it makes a really delicious muffin topping.

    These muffins would be incredible without the peanut butter cup middles and without the peanut butter streusel topping.

    But combined? Omg. You might not think these muffins should be breakfast muffins.

    But you might not care when you wake up in the morning and can't get them out of your mind. Plus, they go so well with coffee.

    And, I mean, if anyone saw you with one at 7 a.m., they would think nothing of it.

    Unless... They happened to cut it open.

    And then. Oops. Your secret will be discovered.

    But come on, two mini peanut butter cups in the morning are nothing to judge anyone on.
