Lemon crunch cupcakes ?

I made lemon cupcakes the other day but before that I was thinking it would be so good to make some kind of lemon crunch cupcakes. I looked on Pinterest to see if there was even such thing as a lemon crunch cupcake (because Pinterest has everything and it's my go to site these days to find what I need), but they did not have a lemon crunch cupcake on there. At least I couldn't find it. So I decided to make up my own recipe for it. I just used brown sugar flower and butter and a little bit of oats for the crunch part and put it on top of my cupcakes. I thought it was quite tasty. I also don't have the exact measurements because I just eyed it.

So, here is my version of a lemon crunch cupcake. I made one with frosting on top and one without. I think it tasted good both ways.
