I had a heck of a time getting this week’s recipe for #SundaySupper made. My first attempt I tried adapting my favorite peanut butter brownie recipe. That didn’t turn out well at all. The blondies tasted good but the texture was off.
I found a recipe at Sally’s Baking Addiction so I decided to try that one. Thankfully that one turned out to be a winner but even it had its challenges since I didn’t have the chance to make them until 3 pm yesterday. I hate being that close to a deadline for a post.
This week’s theme is Lunchbox Ideas and is hosted by Liz from That Skinny Chick Can Bake. I carried a lunch to school everyday up until the fourth grade because until I hit the fourth grade none of my schools had a cafeteria. It was always a ham sandwich, a thermos of milk, some chips, and either a fruit cup or a can of pudding, preferably butterscotch. Yes, I am old enough that the fruit cups and puddings came in pop top cans instead of the plastic containers they are in now.
I would have loved to have this Biscoff White Chocolate Blondies tucked into my lunchbox as a kid because I have a major weakness for white chocolate.

Yummy!!! We love blondies in this house!
I hae some biscoff spread in my pantry and I love blondies! These are calling my name.
I must be the only food blogger that’s never tried Biscoff! Maybe these blondies will change that!
Make that you and me, Cindy 🙂 I have never tried it either 🙂

Congrats on having enough Biscoff in the house to bake with! Mine disappears with a spoon.
Oh gosh, I remember those pop top puddings. They were not so good from what I recall.
I do like Biscoff spread a lot and will have to get another jar and make brownies. Good to know it doesn’t work well to substitute it for peanut butter in other recipes.
Gorgeous, Mimi! Looking forward to baking these lovely gems and sinking my teeth into them =) Thank you for persevering and delivering perfection!
I really need to make some Biscoff… we can’t get it here
These looks truly amazing!!
They look great Mimi! Perfect for a lunch box..especially mine 🙂 Yummy!!
I bet these are so tasty!
Biscoff spread is my new guilty pleasure! These look awesome!

Blondies are delicious all on their own, but adding Biscoff sounds amazing!
