25-Minute Gluten Free Lemon Brownies That Taste Like Sunshine

Author: Oscar

Published: June 17, 2025

Okay, I’m obsessed with these gluten-free lemon brownies – they’re like sunshine in dessert form! My friend Sarah (who’s gluten-intolerant) begged me for years to create a version she could eat, and after about a dozen test batches (sorry, neighbors!), I nailed it. The secret? Using real melted butter and fresh lemon juice-zest combo that makes these brownies unbelievably moist and tangy. They’ve got that perfect chewy-but-soft texture that’ll fool anyone into thinking they’re not gluten-free. Pro tip: eat one warm with your eyes closed and tell me it doesn’t taste like summer vacation.

Ingredients for Gluten Free Lemon Brownies

Here’s everything you’ll need for these zippy little squares of happiness:

1 cup gluten-free 1-to-1 baking flour (I use Bob’s Red Mill, packed lightly)
1/2 cup unsalted butter, melted and slightly cooled
1 cup granulated sugar (yes, the full cup – trust me!)
2 large eggs, room temperature
2 tbsp freshly grated lemon zest (about 2 medium lemons)
3 tbsp freshly squeezed lemon juice
1/4 tsp fine sea salt

Ingredient Notes & Substitutions

The gluten-free flour blend makes all the difference – don’t try subbing almond flour here. For the lemon, fresh is non-negotiable; bottled juice tastes flat. If you’re dairy-free, coconut oil works instead of butter (use refined for neutral flavor). And yes, you could reduce the sugar slightly, but these really need that sweetness to balance the lemon’s punch.

How to Make Gluten Free Lemon Brownies

Alright, let’s turn these simple ingredients into magic! I swear this is easier than remembering to water houseplants (and way more rewarding). Here’s exactly how I make them:

Prep that pan first – Grease an 8×8 inch baking dish and line it with parchment paper (leave some overhang – you’ll thank me later). Preheat your oven to 350°F while you work.
Butter + sugar = love – In a big bowl, whisk together the melted butter and sugar until it looks like wet sand. No fancy mixer needed – just a wooden spoon and some elbow grease!
Zesty business – Beat in the eggs one at a time, then go wild with the lemon zest and juice. Your kitchen should smell like a lemon grove right about now.
Flour power – Gently fold in the gluten-free flour and salt until just combined. The batter will be thick and glossy – don’t overmix or your brownies might get tough.
Bake to perfection – Spread the batter evenly in your prepared pan and bake for 23-25 minutes. You’ll know they’re done when the edges are golden and the center springs back when lightly touched.
The hardest part – Let them cool COMPLETELY in the pan before lifting out with the parchment and slicing. I know, the waiting is torture!

Tips for Perfect Brownies

Use a microplane for the zest – no bitter white pith allowed!
Undermix the batter slightly – a few tiny flour streaks are better than overworked gluten-free flour
Slice with a plastic knife to get clean edges without sticking

Serving and Storing Gluten Free Lemon Brownies

These lemon brownies are absolute perfection with a dusting of powdered sugar while still slightly warm – the sugar melts into the top just enough to make them extra dreamy. For a fancy twist, serve with a dollop of whipped coconut cream and fresh berries. Leftovers (ha!) keep beautifully in an airtight container at room temperature for 3 days. You can also freeze them for up to a month – just separate layers with parchment so they don’t stick together when thawing.

Nutritional Information

Each glorious gluten-free lemon brownie clocks in at about 180 calories – totally worth it for that citrusy happiness! Here’s the breakdown per serving (based on 12 brownies): 8g fat, 25g carbs (18g sugar), and 2g protein. Just a heads up – these numbers are estimates since lemons vary in size and we all know I sneak extra zest sometimes. For special diets, check labels on your specific ingredients!

FAQs About Gluten Free Lemon Brownies

Can I use bottled lemon juice instead of fresh?
Oh honey, no! Bottled juice tastes flat and weirdly metallic in these. Fresh lemons give that bright, zippy flavor we love. Pro tip: microwave your lemons for 10 seconds before juicing to get every last drop!

Why do my brownies sink in the middle?
This usually means you overmixed the batter or opened the oven door too early. Gluten-free flour needs gentle handling – mix just until combined. And no peeking until at least 20 minutes in!

Can I make these dairy-free too?
Absolutely! Swap the butter for refined coconut oil (virgin coconut oil will taste too tropical). I’ve done this for my vegan friends and they gobbled them up just as fast.

How do I know when they’re done baking?
The edges should be lightly golden and the center should spring back when gently pressed. A toothpick should come out with moist crumbs – not wet batter, but not bone dry either. They’ll firm up as they cool!
