Glazed Blueberry Butter Swim Biscuits

These glazed blueberry butter swim biscuits were born from a happy accident last summer when I spilled way too much butter into my biscuit pan. Instead of starting over, I decided to roll with it—and wow, am I glad I did! The butter creates this incredible crispy edge while keeping the insides pillowy soft. Adding fresh blueberries and a sweet glaze transformed my mistake into our new family favorite. My husband now "reminds" me to "accidentally" use the whole stick of butter every time I make biscuits!

My neighbor Janet, who swears she "doesn't do carbs," ate three of these when I brought them to our block party last month! My teenage son's friends now mysteriously appear at our house on Saturday mornings when I'm baking these. And my mother-in-law—who has never asked for a recipe in the 15 years I've known her—finally broke down and requested this one. There's something about that combination of buttery biscuit, sweet-tart berries, and glossy glaze that makes them completely irresistible.

Simple Ingredients

• Buttermilk: Creates that perfect tender crumb and slight tanginess. No buttermilk on hand? I've used the old trick of adding a tablespoon of white vinegar to regular milk and letting it sit for 5 minutes. Works like a charm in a pinch!
• Fresh blueberries: Summer berries are ideal, but I've used frozen plenty of times during winter months. Just don't thaw them first or you'll end up with purple biscuits! Not necessarily bad, just... purple.
• Butter: This isn't the time for substitutes or cutting back. That full stick creates the magic "swim" that makes these biscuits unique. I've tried using less, and while still good, they weren't the same indulgent treat.
• All-purpose flour: Nothing fancy needed here. I've tried using cake flour thinking it would make them more tender, but they actually became too delicate and fell apart. Good old AP flour provides just the right structure.
• Simple glaze: Just powdered sugar and milk creates that perfect sweet finish. Sometimes I add a tiny splash of vanilla or almond extract if I'm feeling fancy, but it's completely optional.

Step-by-Step Instructions

Blueberry prep magic

Creating that perfect jammy berry texture starts with a quick sugar toss. Coating most of the berries with sugar before folding them in helps them release their juices during baking. The first time I made these, I skipped this step and the berries stayed whole—still delicious but not as jammy. That bit of berry juice swirling into the dough creates beautiful flavor pockets throughout the biscuits.

Gentle mixing method

Achieving that perfect tender texture requires a light touch. I use a wooden spoon and stir just until the flour disappears—usually about 15-20 gentle strokes. Overmixing is the enemy of tender biscuits! My first batch turned out like hockey pucks because I mixed the dough until it was smooth. Now I embrace the slightly shaggy, lumpy appearance of properly mixed biscuit dough.

Butter swimming pool

Creating that signature butter-swim magic is simple but specific. Pour that melted butter into the pan BEFORE adding the dough—not after! The dough should float on top of the butter. When I pour the dough in, I use the back of my spoon to gently spread it to the edges without mixing the butter into the dough. During baking, the butter bubbles up around the edges and works its way through the biscuits, creating that incredible texture.

Perfect scoring technique

Getting clean-cut squares after baking starts with proper scoring. I use a butter knife or bench scraper to cut through the unbaked dough, marking where I'll cut later. Don't skip this step! The first time I made these, I didn't score them and trying to cut them after baking was a crumbly mess. The scoring marks mostly disappear during baking but give you the perfect guide for cutting beautiful squares once baked.

Topping strategy

Creating those perfect blueberry bursts on top takes a bit of planning. I save a quarter of the fresh berries to press gently into the top of the dough just before baking. These berries stay more intact and create beautiful pops of color and juicy bites on top. Sometimes I sprinkle the top berries with a tiny bit of coarse sugar for extra sparkle and crunch.

Glaze patience

Achieving that perfect glossy glaze requires cooling time. If you glaze the biscuits while they're still warm, the glaze will melt and disappear into the biscuits instead of creating that beautiful white layer on top. I've learned this lesson the hard way! Now I force myself to wait until they're completely cool, which takes about 30-40 minutes. The glaze sets up perfectly and creates that bakery-worthy finish.

My first attempts at these biscuits had way less butter, and they were good but not amazing. I gradually increased the amount until I hit the perfect ratio of butter to dough. I've experimented with different berries too – raspberries and blackberries are delicious but much juicier, so the biscuits turn out a bit more moist. Strawberries work well if you dice them small. My kids love when I add a handful of white chocolate chips to the dough along with the blueberries, but I find them perfectly sweet without.

Beautiful Baking

These gorgeous biscuits deserve special treatment when serving! For weekend brunches, I arrange them on a pretty cake stand with some fresh berries scattered around for color. They're incredible served slightly warm (after the glaze has set) with a dollop of whipped cream or even a scoop of vanilla ice cream for an over-the-top dessert. During blueberry season, I add a little lemon zest to the glaze for a bright, fresh twist. They pair beautifully with coffee for breakfast or afternoon tea, making them versatile enough for any time of day.

Tasty Twists

These versatile biscuits welcome creative variations while keeping that magical butter-swim texture. For a fall version, I swap the blueberries for diced apples tossed with cinnamon and a bit of brown sugar instead of white. During the holidays, I add dried cranberries and orange zest for a festive twist. My chocolate-loving husband enjoys when I add a handful of chocolate chips to the batter. And for a zesty summer version, try adding a tablespoon of lemon zest to both the biscuit dough and the glaze – it brightens all the flavors beautifully.

Fresh Keeping

These biscuits are definitely best on the day they're made, but if you have leftovers, store them in an airtight container at room temperature for up to 2 days. After that, the butter begins to make them a bit soggy. To refresh day-old biscuits, pop them in a 300°F oven for about 5 minutes – they'll regain some of that wonderful texture. I rarely have leftovers since my family devours them, but when I make them specifically for smaller gatherings, I sometimes halve the recipe and bake in a smaller pan with excellent results.

Pin it

I stumbled upon these glazed blueberry butter swim biscuits by accident, but they've become our most requested weekend breakfast treat. There's something about that combination of crispy, buttery edges, tender middles, juicy berries, and sweet glaze that makes them completely irresistible. While they're definitely an indulgent treat rather than an everyday breakfast, sometimes life calls for a little extra butter and sweetness! The fact that they're so simple to make yet look so impressive makes them perfect for both family breakfasts and special occasions.

Frequently Asked Questions

→ Can I use frozen blueberries?

Yes! You can use frozen blueberries without thawing them first. This helps prevent them from bleeding too much color into the batter.

→ What if I don't have buttermilk?

You can make a substitute by adding 2 tablespoons of lemon juice or white vinegar to 2 cups of regular milk. Let it sit for 5 minutes before using.

→ Why do I need to let the biscuits cool before glazing?

If the biscuits are too warm, the glaze will melt completely and soak in rather than sitting on top for that beautiful finish.

→ Can I make these ahead of time?

These biscuits are best enjoyed fresh and warm, but you can make them up to a day ahead. Reheat gently in the microwave or oven before serving.

→ Can I add other fruits besides blueberries?

Absolutely! Try diced strawberries, raspberries, or blackberries. Just make sure they're similar in size to blueberries, or chop larger fruits into smaller pieces.
