Why This Recipe Works

Feeds a crowd — This recipe for oatmeal butterscotch brownies makes a whole big pan. Great for a quick dessert for yourself or guests or great for those holiday gatherings where you don’t want to show up empty-handed. 

Coconut — Now, before you read “coconut” and move on to another recipe: Hear me out. Adding coconut gives these oatmeal butterscotch blondies an extra texture, moisture (and just the tiniest hint of coconut flavor) you didn’t know you were missing. If you absolutely cannot even with the coconut (or are allergic), read below for some great substitutions. 

Browned Butter — Here’s another little tweak you maybe wouldn’t think of trying but makes all the difference. Browning your butter simply means melting the butter in a pan and then letting it cook a little longer until it reaches a deep golden color. That’s all! So easy and it adds so much flavor and goodness that you’ll wonder why you ever made anything with regular melted butter.
Coarse sea salt — A third “must-have” ingredient is coarse sea salt. I have been wanting to try it out in my recipes for-ever and finally bought some last week. I used it in these butterscotch blondies and my reaction was basically this: Holy cow where have you been all my life! (And then I proceeded to hide the rest of these butterscotch blondies so no one else could have any.) So my point is, do it! Do the sea salt. You will not regret it.

Ingredients

ingredients for oatmeal butterscotch blondies
  • Coconut Flakes — Any old coconut flakes will do. One note though: check the expiration date. The fresher, the better. They’ll be more moist and tender and soak up that browned butter oh-so-well if they’re fresh. 
  • Butter — Any butter will work here. Salted, unsalted, you can use what you have to brown in the pan. 
  • Brown Sugar — Brown sugar provides the oatmeal butterscotch blondies with their sweetness and color. 
  • Eggs — Eggs help bind the blondies together. 
  • Vanilla — I prefer to use all natural vanilla whenever possible, but you can also use imitation if you prefer. 
  • Butterscotch Chips — found with the white and regular chocolate chips at the grocery store.

Here’s How You Make It

steps 1-6 for making oatmeal butterscotch bars
  1. First, preheat your oven to 350, then line a 9×13 inch baking dish/pan with nonstick foil and spray with cooking spray.
  2. Next, brown that butter by melting it in a medium saucepan over medium-high heat. Keep cooking the butter for about 3-5 minutes or until the butter becomes a dark amber/golden color, then remove it from the heat. 
  3. While the butter is browning, add coconut flakes to a medium pan and cook over medium-high heat for just 3-5 minutes, stirring the entire time. When the flakes begin to brown, take them off the heat, being careful not to let them burn.
  4. In another medium bowl whisk together the dry ingredients: flour, baking powder, 1 teaspoon salt, and oats. 
steps 7-12 for oatmeal butterscotch blondies recipe
  1. Next, mix together the browned butter, brown sugar, eggs, and vanilla in a large bowl. Add to the mixture the toasted coconut flakes, stirring again until smooth. 
  2. Gradually stir the flour mixture into the wet ingredients until all the ingredients are incorporated. Add in 1 tablespoon of milk to help bring the blondies together, then gently stir in the butterscotch chips right before baking. 
  3. Press the oatmeal butterscotch blondies into your prepared pan and bake them for 20-25 minutes, or until the mixture is set and the top looks dry. Remove them from the oven and immediately sprinkle with the remaining 1/2 teaspoon of sea salt. Allow the bars to cool completely before cutting and serving.

FAQS

What Are Some Substitutions for Coconut?

Not a fan of coconut? It’s okay, I promise! Here are some options for substituting the coconut out in these butterscotch blondies. 
First, just simply omit the coconut from these bars. They will still be delicious! 
If you’d like to add a little something to your blondies I recommend adding bits of a candy bar. My favorites include Snickers, Heath bars, toffee, or even M&Ms. 
Sliced almonds or walnuts would also make for a nice taste and extra crunch. 
Double up the chip deliciousness and use chopped white chocolate or your favorite other type of chocolate chip in these blondies.

What Makes a Blondie Different from a Brownie?

Brownies, blondies, what’s the difference? Well first of all, brownies use melted chocolate or cocoa powder to make them, well, brown and chocolatey. Blondies, however, use brown sugar as the key ingredient to make them look and have the texture of a brownie but without the chocolate base.

Expert Tips & Tricks

  • Store in an airtight container at room temperature up to five days or freeze the cut blondies in a ziplock bag or container for up to 3 months. 
  • Coconut can go bad easily, so it’s important to store it properly. Keep it in an airtight container in the fridge or freezer. 
  • Be careful not to overbake your blondies. Too much time in the oven can cause them to crumble.
