    Really good! I loved the rhubarb x white chocolate combo. I would say this was closer to a super moist cake than chewy blondie texture. Edit: super good a day later in the fridge

    I've had the experiences noted below, so I tried something different. I made these in a 9x9 pan, because I needed more than 9 cookies! I baked them 35 minutes even though I would have thought they needed less. They were not soggy or gooey in the middle, which is what happened when I made it in the 8" pan and baked it for 30. I also made sure I cut the rhubarb into small dice, smaller than noted. With these adjustments, they were perfect.

    Tasty although very sweet. The recipe calls for 4 kinds of sugar! As Anya Sf notes, it took about 35 minutes to feel set. (The recipe says 20-25). I wouldn't make this again.

    I used a bit more rhubarb and would do so again, as the tartness balances the super-sweet blondie dough and white chocolate. I substituted pecans for almonds. My rhubarb was frozen, which may have affected the baking time. The blondies only seemed "just set" after 35 minutes, although the top was still quite soft, but a toothpick came out clean, so I removed them from the oven. After cooling, the center was still too gooey for my taste, but the edge pieces were perfect (drier than I'd prefer in a regular blondie). My family loved these. Storage note: after 2 days at room temperature, they were getting quite soft from the fruit.
