Mexican Coke Blondies Are the It-Girl Dessert of the Moment

Hi friends!

Ever had a 3:42 AM brain blast that makes zero sense until weeks later? That was me, half-asleep, scribbling down a weird idea that somehow turned into Mexican Coke Blondies. Yep, blondies made with soda, think retro soda shop vibes meets chewy, buttery, bubbly sugar rush. And the kicker? They’re 100% Kacie-safe. No cocoa, nuts, seeds, coconut, oats, or fake sugars messing with the flavor. Just a nostalgic dessert that tastes like it jumped straight out of 1959 with a cherry on top. Let me tell you how this midnight madness became my new favorite treat.

MEXICAN COKE BLONDIES

This is not your basic blondie. She’s chewy. She’s rich. She’s sweet in a “my grandma made this” kind of way, with a flavor curveball that keeps people guessing. That flavor? Reduced Mexican Coke, baby.

It's subtle and sticky and deep like caramel and cola had a baby and decided to rig the bake sale.

Honestly? People will eat one and go “Wait… what’s in this??” ... And then eat three more.

What You’ll Need:

DRY INGREDIENTS:

  • 1 ½ cups organic unbleached all-purpose flour

  • 1 tsp baking powder

  • ¼ tsp salt

WET INGREDIENTS:

  • ½ cup grass-fed butter melted and slightly cooled

  • 1 cup light brown sugar

  • 1 egg + 1 egg yolk

  • 2 tsp vanilla extract

  • ¼ cup Mexican Coke syrup (see below)

How to Make Mexican Coke Syrup:

Ingredients:

  • 1 cup Mexican Coke (the kind in the glass bottle, sweetened with real cane sugar only)

Instructions:

  1. Pour it into a small saucepan and bring to a gentle boil.

  2. Reduce the heat and let it simmer until you’ve got about ¼ cup of syrup left.

  3. Stir occasionally and DO NOT walk away — this stuff will go from perfect to scorched real quick.

  4. It’ll take around 15–20 minutes and should coat a spoon without being too thick.

Let it cool before using.

Optional Add-ins (Low-Nickel Approved & Aesthetic AF):

You don’t need these, but if you wanna serve main character dessert energy:

  • Crushed freeze-dried strawberries (they bring a tangy sparkle that cuts the sweetness)

  • White chocolate chips

  • Maraschino cherries

  • A lil lime zest (for a subtle Coke-with-lime punch)

If you want to be obnoxiously cute, do all of the above and maybe a little extra lime juce and tell people it’s your “Cherry Limeade Blondie Era.”

HOW TO MAKE THEM:

1. Prep the Scene

  • Preheat your oven to 350°F.

  • Line an 8x8 baking dish with parchment paper and butter the sides.

2. Whisk the Wet

  • In a large bowl, whisk together melted butter and brown sugar until it’s glossy, smooth, and a little thick.

  • Add in the egg, egg yolk, vanilla, and your cooled Mexican Coke syrup.

  • Stir until it’s creamy and luscious.

3. Mix the Dry

  • In another bowl, whisk flour, baking powder, and salt.

  • Add the dry to the wet and stir just until combined. Don’t overmix unless you like tough blondies. (You don’t.)

  • Fold in any of the fun extras here.

4. Pour & Smooth

  • Pour the batter into your prepared pan and use a spatula to smooth the top.

5. Bake the Magic

  • Bake for 22 to 26 minutes, until the edges are golden and the center looks just set. If it smells like a soda fountain and caramel candy had a baby? It’s done.

6. Cool It, Babe

  • Let them cool all the way before cutting. I know, it’s so rude. But this helps them set and develop their flavor.

7. Serve It Cute

  • Cut them into squares and sprinkle with a little flaky sea salt or some powdered sugar if you’re in a ✨ presentation mood ✨

  • Serve with a scoop of vanilla bean ice cream or a dollop of organic greek yogurt if you want to play with balance. It’s a vibe.

Notes from the Lab:

  • These are sweet. They are not a bland protein bar moment. They are a treat. That’s the point.

  • Balance with fat or tang: Think Greek yogurt, or creamy vanilla ice cream.

  • Only use real cane sugar soda. This is not the time for corn syrup sludge or sugar-free imposters.

  • Do not use Diet Coke, Coke Zero, or anything “light.” You need real sugar to get that sticky syrup magic.

  • Wanna be extra? Add a single drop of almond extract to the batter (if tolerated).

Alternate Flavors You Should Definitely Steal From Me:

Once you nail this (and you will), here are a few versions to experiment with:

  • Root Beer Float Blondies: Swap Coke or Root Beer and add a swirl of vanilla bean cream cheese to the batter before baking, and thank me later.

  • Cream Soda Blondies: Swap Coke syrup for cream soda syrup, and add a pinch of nutmeg and some mini marshmallows for chaos.

  • Cherry Coke Blondies: Use freeze-dried cherries, a dash of almond extract (if your body says yes), and a little extra vanilla.

FAQs About Mexican Coke Blondies

Q: What makes Mexican Coke better for blondies than regular Coke?
A: Mexican Coke uses real cane sugar instead of corn syrup, which caramelizes beautifully when reduced into syrup, giving your blondies that rich, sticky, retro flavor no diet or “light” soda can match.

Q: Can I use Diet Coke or Coke Zero for this recipe?
A: Nope. The magic comes from the real sugar in Mexican Coke. Diet versions won’t reduce properly and will kill the flavor and texture.

Q: Are Mexican Coke Blondies safe for a low-nickel diet?
A: Absolutely. No nuts, seeds, oats, or coconut here. Just clean ingredients and that cheeky soda syrup for a sweet kick without triggering nickel sensitivities.

Q: How do I make Mexican Coke syrup without burning it?
A: Keep a close eye! Simmer gently and stir often. It takes about 15–20 minutes to reduce to syrup. Walk away, and you’ll get scorched caramel instead of candy magic.
