What is a biscuit bomb?

I first started seeing people take canned biscuit dough, you know, the Pillsbury kind and stuff it with cheese, bake it up golden, and call them “biscuit bombs.” And I thought… why not make a sourdough version?

This discard dough is so soft, buttery, and flaky, it makes the perfect base for holding melty cheese, savory meats, fresh herbs, you name it. Honestly, now my brain’s swirling with sweet ideas too. Jam? Chocolate? Cinnamon sugar? The possibilities are endless once you’ve got this dreamy dough.

How to make sourdough cheese-stuffed biscuit bombs: step-by-step

Ingredients

• 250 grams all-purpose flour
• 2 teaspoons baking powder
• 1 teaspoon salt
• 113 grams cold unsalted butter, grated
• 21 grams honey
• 200 grams sourdough discard (cold)
• 80 grams cold buttermilk (or heavy cream)

For the filling:

• 120 grams (4 oz) cheese cut into 1 inch cubes (I prefer mozzarella)
• optional add-ins: bacon bits, jalapenos, chives, etc.

For the garlic butter topping:

• 60 grams unsalted butter melted
• 2 garlic cloves minced
• 1 teaspoon Italian seasoning
• 20 grams Parmesan cheese grated

Equipment

• Mixing bowl
• Food scale
• Cheese grater
•  1 9×9-inch baking pan (8×8 inch works too)
• Parchment paper

Instructions

*Place the butter in the freezer for 15-20 minutes

• In a large bowl whisk together the flour, baking powder, and salt.

• Grate the frozen butter into the mixture and use a fork or a dough scraper to cut the butter into the mixture until it resembles coarse crumbs.

• In a separate bowl whisk together the honey, sourdough discard, and buttermilk or heavy cream.

• Add the wet mixture to the dry and mix until a shaggy dough is formed. Dough should be soft, but not sticky.

Shaping the biscuit bombs

• Before shaping the biscuit bombs ensure your cheese has been cut into 1 inch cubes and line your baking pan with parchment paper or spray a little non-stick oil in it.

• Lightly flour your work surface and weigh the dough and cut it into 12 equal pieces.

• Take each piece of dough, flatten it out a bit, and add a cube or 2 of cheese (around 10 grams) to the center. Pinch the dough around the filling and gently roll into a ball.

• Place each sourdough biscuit bomb into the baking pan, cover the pan and refrigerate the dough for 30-60 minutes.

Why do we refrigerate the dough? Refrigerating the dough allows the butter to harden creating beautiful flaky layers once baked.

Brush & Bake the biscuit bombs

• Preheat the oven to 425 degrees F once ready to bake the sourdough biscuit bombs.

• Grate the Parmesan cheese and set aside. Melt the butter and mix in the minced garlic & seasoning.

• Liberally brush the garlic butter over the biscuit bombs and sprinkle the grated Parmesan cheese over top, Save any remaining garlic butter for brushing after baking.
  

• Bake for 15-20 minutes or until desired golden brown. Rotate the pan halfway through for even browning.

Pro tip: To ensure your biscuit bombs are baked through, aim for an internal temperature of 200–205°F (93–96°C) in the center.

• Optional finishing touch: brush with more garlic butter after baking and top with fresh herbs. They pair wonderfully with marinara sauce!

• Sourdough cheese-stuffed biscuit bombs are best served warm but can be reheated in a toaster oven or air fryer. Keep them in an airtight container for 1-2 days on the counter.
