What Are Blondies?

Blondies are dessert bars similar to brownies but without chocolate. They feature a caramel-like flavor from butter and brown-style sugar (this version uses coconut sugar). Blondies are dense, chewy, and tender — perfect for anyone who prefers something sweet and buttery over a traditional brownie.

Ingredients for Apple Blondies

Labeled ingredients for gluten-free apple blondies.

Full ingredient amounts are in the recipe card below. Key notes and swaps are listed here:

  • Green apple – Tart Granny Smith works best, but any crisp apple is fine.
  • Gluten-free flour – Use an all-purpose gluten-free blend. Regular flour works if you don’t need GF.
  • Coconut sugar – A natural alternative to brown sugar; brown sugar can be substituted.
  • Butter – Unsalted butter is recommended. Grass-fed or high-quality butter adds flavor.
  • Pure maple syrup – Use real maple syrup for best taste and clean ingredients.

Step-by-Step Instructions

⭐ Pro Tips ⭐

  • Line the pan: Spray the pan lightly, then line with parchment that hangs over two sides to remove bars easily.
  • Add nuts: Fold in ½ cup chopped walnuts or pecans with the apples for crunch.
  • Don’t overmix or overbake: Mix just until incorporated and remove from the oven when just set for a chewy center.
  • Refined sugar-free glaze: Use powdered coconut sugar for a refined sugar-free glaze alternative.
  • Glaze consistency: The glaze should be pourable but thick so it doesn’t soak into the bars.

Recipe FAQs

What type of apples are best for baking?

Granny Smith is recommended for its tartness, which balances the sweetness. Other crisp varieties like Honeycrisp also work well.

Can I use a different sized pan?

Yes. A 9×9 pan will yield slightly thinner bars and may reduce bake time by 3–5 minutes. You can double the recipe for a 9×13 pan.

Do I have to add the glaze?

No, the glaze is optional but recommended. For a refined sugar-free option, use powdered coconut sugar in the glaze.

Can I make these dairy-free?

A plant-based butter substitute should work, though results may vary. If you try it, adjust as needed and note texture differences.

How to Store These Blondies

Storing: Keep the bars at room temperature up to 3 days, or refrigerated up to 5 days. Note the glaze may absorb into the bars over time — they’re best the day they’re made.

Freezing: Freeze up to 3 months. For best results, freeze without the glaze and add the glaze after thawing.
