You know when you bite into something and you think it might actually be the best thing you ever ate?

These peanut butter cup brownie cupcakes are just like that. One bite and you think Oh my god, where have you been all my life, you amazing dessert? Why have I never had you before?

And then you also think, oh my merciful heavens, how can this decadent treat possibly be keto? Is someone playing a trick on me? Have I accidentally picked up my friend’s dessert instead? Am I losing my ever-loving mind?

Rest assured, dear reader, you are not losing your mind. And you haven’t been tricked or accidentally fallen face first into a plate of forbidden high carb brownie cupcakes.

All is well and you are safe. They really are keto and they really are that amazing. And they are deliciously easy to make, too.

Inspiration for peanut butter brownie cupcakes

New developments in the keto world have made these glorious keto brownie cupcakes possible.

Not least among them are the new no sugar added treats by ChocZero. They now make their own peanut butter cups, and they are all absolutely delicious.

I often make my own keto peanut butter cups and they are wonderful. But while they are pretty simple to make, it’s nice to have someone else do the work for a change. Plus I always see these high carb recipes stuffed with peanut butter cups and they always look so good.

For a while now, I’ve been jealous that they have ready options and I don’t. But now I do. Hooray!

I actually intended to make these brownie cupcakes even easier by using ready-made keto brownie mix by Good Dee’s. But as luck would have it, I actually had the chocolate cake mix in my pantry and not the brownie mix.

Although peanut butter cup stuffed chocolate cupcakes would also be very good, I had rich fudgy brownies in mind and I really really wanted that. So I made the batter for my own keto brownies, which are incredibly easy anyway.

You could do it either way and the results would be amazing. Mine were so good, I thought I’d died and gone to heaven!

Traveling with keto desserts

I loved these keto treats so much that a few of them actually traveled with me all the way to Austin, Texas for KetoCon. I’d made them the day before I went, and I left the bulk of them behind for my kids and husband.

But they were so delicious, I couldn’t bear to leave them all behind. So I squirrelled two away in my carry on and it was so wonderful to have such a delicious treat waiting for me back in my hotel room. They actually traveled surprisingly well!

How to make Keto Brownie Cupcakes from scratch

I realize that some of you may want to make these decadent stuffed brownies from scratch. That is possible too, my friends. Here’s what you would do:

Make a batch of my low carb peanut butter cups. Let them cool and refrigerate or freeze before adding them to your brownies. You may need to make them a bit smaller so that you can get 15 out of them for the recipe.
Mix up the keto fudgy brownie batter and follow the directions below for assembly and baking.
Make the chocolate peanut butter glaze as directed below.
Eat and be happy!

Definitely more work involved doing it this way but also very tasty!
