Berry Yummy: Blueberry Swirl Muffins

Blueberry Muffins are literally the best. (Especially those Costco ones, like gimme… Seriously.) But when regular Blueberry Muffins aren’t just gonna cut it, I present to you: Blueberry Swirl Muffins! *applause* Why thank you. So how is a Blueberry Muffin and a Blueberry Swirl Muffin any different? you may ask. Well, basically instead of placing whole blueberries into muffin batter, you reduce the blueberries down into a sticky sauce and swirl it into the batter. Sure, it’s a little more work, but it looks super pretty and it’s super tasty! Wanna know how to make ’em? Keep on reading…


Short story: I actually made these muffins because I was going on a trip that didn’t involve airplanes or anything complicated like that; it involved a long car ride and a hotel. Since this hotel isn’t one of those fancy ones that have yummy breakfast, and I’m not going to go to a restaurant for breakfast, I whipped up a batch of these bad boys before I left. They pack super well, don’t melt/disintegrate/make a mess, and are individually wrapped in single-serving packages, so they’re perfect food for those of you on the go!

Seriously guys, try these muffins. Especially since blueberries are so sweet and ‘nummy right now! (As you can tell I’m scrambling for stuff to say, ’cause I should be writing something here, but my mind is completely blank…) So, yeah. Have a nice day! Have a fun summer! Have a great life! Have a Blueberry Swirl Muffin!
