There’s just something about dessert that makes me get all excited. Friends are coming over, hooray! Friends are coming over for dessert, bust out the marching band and parade! Our Mudslide Blondies or Hershey’s chocolate chip blondies are perfect for hanging out with friends and family. Isn’t food just so much better when you share it with someone else? Unless it’s a little chocolate bar and your children are involved. Or these cookies and cream brownies. I devour those.

Let’s be honest, sometimes there’s nothing in the world that sounds better than a quiet house, awesome tv show and a little special treat for you. The other night we had plans to put the kids to bed and watch a movie with warm blondies and ice cream. Doesn’t that sound perfect? Until we headed to redbox and couldn’t find a single thing. And Netflix was a bummer too. In fact, if you follow me on instagram you may have even noticed that I asked what you like to watch on Netflix just to still move forward with our plan.

And do you know what we ended up watching? Cosmos. Haha, not at all what you all recommended but it was fascinating! Space actually creeps me out a little, but not for the reason you may think. It’s not that I’m afraid of martians, but it’s the whole heights thing. Gosh, it would be so creepy to be floating around out there!

Wait, I got off subject. We aren’t talking about floating through space but instead about the beauty of space. In fact, this is one of those times I think science actually does point to a God instead of trying to disprove His existence. It was cool to learn that science agrees with the creation story in Genesis. Everything happened in an order. Can you believe that just in our galaxy there are 8.8 BILLION worlds that are habitable?! That’s nuts! Um yes, I’m going to go ahead and agree with the scripture that God creates worlds without number. You can read it here. I actually love this entire chapter. I love whenever God calls someone his “Son”. Such a lovely reminder that He is there and mindful of us.

Anyway, that movie you guys, space is awesome. Like, for real.

Why Are My Blondies Greasy?

The biggest culprit in greasy blondies is mixing mistakes, not too much oil.

The eggs and sugar need to be well blended.

You should mix sugar and eggs together until they are light, thick and pale in color.

Proper aeration is essential to perfect blondies.

How Long Will Blondies Keep?

Stored properly, blondies will keep for 3-4 days at room temperature.

Wrap tightly or place in an airtight container and store up to a week in the fridge.

You can also freeze up to 3 months.

Are Blondies Cookies or Brownies?

Blondies are a dessert bar, much like brownies. They are made with brown sugar and vanilla instead of the white sugar and cocoa that is used in brownies. Blondies are pretty much vanilla brownies.

  • Baking these now- followed directions perfectly and baked 15 minutes, then covered with foil, And baked another 10 minutes and took them out and the entire middle was still down. So they are currently back in the oven on the 35th minute and not done yet!! How long really are you supposed to bake these? And I am a baker so I know what I’m doing but these are not turning out very well.

    • Every oven cooks a little differently. Bake until it is set in the middle.

  • Hello,
    I’m not clear on the cooking time. I apologize. Do you cook these for 20-25 minutes and then tent with foil and bake another 10 minutes? Thanks!

    • Hi Lyn, you bake them for 20-25 and during the last 10 minutes you tent with foil, or in other words, bake for 10-15 minutes, tent with foil and bake an additional 10 minutes. 🙂

  • Hi – Carrian,
    I am in the process of making these, recipe states to add vanilla, but doesn’t say how much. Also, should this recipe have any baking soda or baking powder? I used 2 XL Hershey’s Bars and they didn’t quite cover the pan, are they to be broken apart and kind of spaced out?

    • Hi Tracy, there should be 1/2 teaspoon of vanilla showing. We’ve had a few errors with the recipes lately so let me know if it isn’t showing. We use two large packages of hershey’s bars that has multiple candy bars inside. We lay them very close together so each bar is touching and break some up to fill in any gaps. 🙂

      • Yes- I see the vanilla now!

  • I don’t know that if I made these, I would want to share them with anybody! YUM 🙂
