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 tablespoon 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.
