These blondies start with browning the butter, which takes about five minutes and changes everything. The milk solids turn golden and the whole pan smells like toasted hazelnuts. That depth carries through every bite.
Spelt flour keeps the texture close and fudgy rather than cakey. It has a mild, slightly sweet flavour that doesn’t fight the apple or the brown sugar.
The apple pieces stay soft but hold their shape. They add moisture and a quiet tartness that balances the richness of the butter and sugar.
You can have these in the oven in fifteen minutes. The batter comes together in one bowl, and there’s no mixer needed.
Why You’ll Love This Recipe
- Brown butter adds deep, toasted flavour with no extra effort.
- Spelt flour keeps the texture fudgy, not cakey or dry.
- Fresh apple pieces stay soft and add natural moisture.
- One bowl, no mixer, ready in under 40 minutes.
Ingredient Notes
- Spelt flour: Use white spelt flour for the lightest texture. Wholegrain spelt works but gives a denser, more bread-like result. Plain all-purpose flour is a direct swap if needed.
- Unsalted butter: Browning butter takes 4 to 6 minutes over medium heat. Watch for golden milk solids at the bottom of the pan and a nutty aroma, then pull it off the heat immediately.
- Light brown sugar: Light brown sugar gives a mild caramel flavour. Dark brown sugar intensifies that and makes the blondies slightly stickier and darker in colour.
- Apple: A firm, slightly tart variety like Braeburn or Granny Smith holds its shape best during baking. Sweeter softer apples like Golden Delicious work but will break down more.
- Vanilla extract: Pure vanilla extract works well here. You can swap it for 1 tsp of ground cinnamon if you want a warmer spiced note in the base.
- Egg: One large egg is enough to bind the batter and keep the texture fudgy rather than crumbly. Use it at room temperature for even mixing.
Spelt Brown Butter Apple Blondies
Description
Brown butter and spelt flour work together here to create a dense, fudgy bar with a toasted, slightly nutty base that pairs cleanly with soft cooked apple pieces.
Ingredients
Instructions
- Heat the oven to 175 C / 350 F. Line an 8-inch square baking tin with parchment paper, leaving an overhang on two sides.
- Melt the butter in a medium heavy-bottomed saucepan over medium heat. Continue cooking, stirring occasionally, for 4 to 6 minutes until the foam subsides and the milk solids at the bottom turn golden brown and smell nutty. Pour into a large mixing bowl and leave to cool for 10 minutes.
- Whisk the light brown sugar into the cooled brown butter until combined. Add the egg and vanilla extract and whisk until the mixture is smooth and slightly thickened, about 1 minute.
- Add the spelt flour, baking powder, and sea salt. Fold in with a spatula until just combined and no dry streaks remain. Do not overmix.
- Add the diced apple and fold through the batter evenly.
- Scrape the batter into the prepared tin and spread it into an even layer. The batter will be thick.
- Bake for 22 to 25 minutes until the edges are set and golden and the centre has a very slight wobble when you gently shake the tin. A skewer inserted 2 cm from the edge should come out with moist crumbs, not wet batter.
- Remove from the oven and leave to cool in the tin for at least 20 minutes before lifting out and slicing into 16 squares.

Note
Additional Notes
- Brown butter at medium heat only - high heat burns the solids before they turn golden.
- Cool brown butter to room temperature before mixing in the egg to avoid scrambling.
- Do not overmix the batter once flour is added or the blondies turn tough.
- Use a metal baking tin for even heat distribution and a cleaner bake.
- Rest blondies in the tin for 20 minutes after baking before cutting for cleaner squares.
