Instant Pot Muffins: Soft, Steamed Breakfast Muffins

Instant Pot muffins are small, tender blueberry muffins steamed under pressure rather than browned in an oven. This simple batter uses everyday ingredients and silicone muffin cups; the result is moist and soft, with a lighter top than a traditionally baked muffin.

Ingredients

1½ cups (180 g) all-purpose flour
⅓ cup (67 g) granulated sugar
1½ teaspoons (6 g) baking powder
¼ teaspoon (1.5 g) fine salt
½ teaspoon (1.3 g) ground cinnamon, optional
1 large egg (about 50 g without shell), at room temperature if convenient
½ cup (120 ml) milk
¼ cup (60 ml) neutral oil, such as canola or sunflower oil
1 teaspoon (5 ml) vanilla extract
¾ cup (110 g) blueberries, fresh or frozen
1½ cups (355 ml) water for the pressure cooker
6 standard silicone muffin cups, plus a piece of aluminum foil large enough to loosely cover them

Instructions

Prepare the cooker and cups. Pour 1½ cups (355 ml) water into the Instant Pot’s inner pot and set the trivet inside. Arrange six silicone muffin cups on a flat tray or in a shallow heat-safe dish that fits on the trivet. If your cups stand firmly on the trivet without a tray, you can use them that way. Lightly coat the inside of each cup with oil spray or a thin film of oil so the muffins release easily. Leave enough room around the cups for steam to circulate.
Mix the dry ingredients. In a medium bowl, whisk together the flour, sugar, baking powder, salt, and cinnamon, if using. Breaking up any flour or baking-powder lumps now helps the muffins rise evenly. In a second bowl, whisk the egg, milk, oil, and vanilla until combined. The ingredients do not need to be perfectly warm, but very cold milk can make the oil look slightly thick or streaky; whisk until the mixture is uniform.
Make the batter and add the berries. Pour the wet mixture into the dry ingredients. Stir with a spoon or flexible spatula just until no large dry pockets remain. The batter should look thick and a little lumpy. Do not beat it smooth, since overmixing can make the muffins firm and chewy. Fold in the blueberries gently. If using frozen berries, add them straight from the freezer rather than thawing them, which can tint the batter and make it wetter.
Fill the cups. Divide the batter among the six prepared cups, filling each about two-thirds to three-quarters full. Avoid filling to the rim; the muffins need room to expand, and overfilled cups may stick together beneath the foil. Set the cups on the tray or dish, then cover them with foil, leaving a little space above the batter. The foil keeps condensation from dripping onto the muffin tops, but it should not press against them.
Cook under pressure. Lower the tray or dish onto the trivet. Lock the lid, set the steam-release valve to sealing, and select Pressure Cook or Manual on High for 25 minutes. Allow about 8 minutes for the cooker to come to pressure; the exact time depends on the model and the temperature of the water. When the cooking time ends, let the pressure release naturally for 10 minutes, then carefully release any remaining pressure. Keep your hands and face away from the valve, where hot steam escapes.
Check doneness and cool. Lift out the tray with heat-safe mitts and remove the foil carefully, directing steam away from you. The muffins should look set and a toothpick inserted in the center should come out without wet batter; a few moist crumbs or blueberry marks are fine. Because the batter contains egg, the USDA FSIS safe minimum for egg dishes is 160°F (71°C); check the center of a muffin with a food thermometer if you need to confirm it. Let the muffins rest in their cups for 5 minutes, then loosen the edges and turn them out to cool. The tops will be pale because pressure steaming does not brown them like oven baking.

Tips

Use cups that fit your cooker. Standard silicone cups are convenient because they release the muffins cleanly and are easy to lift out. Check that the tray or dish sits level on the trivet and that the lid closes without touching the foil. Do not place the cups directly on the bottom of the inner pot; they need to sit above the water.
Measure flour without packing it. Spoon flour into the measuring cup and level it, or weigh 180 g. Scooping and compressing flour can add too much, making a small batch dry or dense. If the batter seems unusually stiff before the berries go in, check the measurement rather than adding extra milk right away.
Keep the mixing gentle. Stir only until the dry ingredients are incorporated, and fold berries in with a few broad strokes. If you use frozen berries, the batter may look a little firmer as it chills; that is normal. Do not compensate by mixing for a long time, since that develops gluten and can toughen the crumb.
Expect a steamed finish. These muffins are meant to be tender and moist, not crisp or deeply golden on top. A dry toothpick alone can be misleading if it passes through a berry, so check another spot or use a thermometer. If the center still contains raw batter, return the cups to the cooker and pressure-cook for 2 to 3 more minutes, followed by a 5-minute natural release.

Serving Suggestions

Serve the muffins warm or at room temperature, either plain or split and spread with butter. A spoonful of yogurt alongside makes a simple breakfast, while fruit, scrambled eggs, or a bowl of oatmeal can turn the muffins into part of a more filling brunch. Since the tops stay soft rather than crisp, they are especially easy for children to eat without crumbs scattering across the table.

For a little extra contrast, add a light dusting of powdered sugar just before serving, or offer honey or jam on the side. Blueberries bring enough sweetness for many tastes, so consider tasting one before adding a sweet topping. If serving a group, put the muffins in a basket lined with a clean cloth and leave them uncovered until ready to eat; trapping steam under a lid can make the tops damp.

Variations

Swap the fruit: Replace the blueberries with ¾ cup (about 110 g) chopped strawberries, raspberries, or peeled diced apple. Juicy fruit can soften the crumb, so keep the total amount close to the recipe’s measure and pat very wet fruit dry first. For apple muffins, the cinnamon is a natural fit; a pinch of nutmeg can be added if you like a warmer spice flavor.

Make them lemon-blueberry: Add 1 teaspoon (about 2 g) finely grated lemon zest to the sugar and rub it between your fingertips before mixing. This releases the fragrant oils and gives the muffins a bright citrus aroma without adding extra liquid. You can also replace the vanilla with ½ teaspoon (2.5 ml) vanilla plus ½ teaspoon (2.5 ml) lemon juice, though the zest gives the clearest lemon flavor.

Try chocolate chips: Replace the berries with ½ cup (85 g) mini chocolate chips, or use ½ cup (85 g) chips and ¼ cup (about 35 g) berries for a mixed version. Mini chips distribute more evenly through this small batch. For a less sweet muffin, choose bittersweet chips and reduce the sugar by 1 tablespoon (12 g); the finished crumb will be slightly less sweet but should still hold together.

Use whole-wheat flour in part: Substitute up to ½ cup (60 g) of the all-purpose flour with whole-wheat flour. Replacing all the flour can make these steamed muffins noticeably heavier, so start with a partial swap. If you use a coarser whole-wheat flour, let the mixed batter stand for 5 minutes before folding in the berries so the bran can absorb some liquid.

Storage and Reheating

Cool the muffins fully, then store them in an airtight container. Refrigerate them within 2 hours of cooking; they keep for 3 to 4 days in the refrigerator. A paper towel under the muffins can absorb excess moisture, and another laid loosely on top helps prevent condensation from collecting on the soft surfaces. For the best texture, let a refrigerated muffin sit at room temperature briefly before eating.

To reheat one muffin, microwave it on a plate for about 10 to 15 seconds, then add a few seconds if needed. For several muffins, warm them covered in a microwave in short intervals so they do not become rubbery. You can freeze cooled muffins in a freezer-safe bag or container for up to 2 months; thaw them overnight in the refrigerator or at room temperature for about an hour, then warm briefly. Reheat leftovers to 165°F (74°C) if reheating them for food safety.

Frequently Asked Questions

Can I make Instant Pot muffins without silicone cups?
Use a small heat-safe dish or muffin tray that fits on the trivet, and grease it well. The cooking time may vary if the batter is in one larger pan rather than individual cups, because a deeper center takes longer to cook. Check the middle for wet batter and use a food thermometer to confirm the egg-containing muffin reaches at least 160°F (71°C).

Can I use paper muffin liners?
Paper liners work best when placed inside a firm silicone cup or metal muffin well. By themselves, they may spread or become damp as they sit above the cooker water. Grease the silicone cups lightly even when using paper liners, since moisture can make the paper cling to the muffin.

Why are my muffins pale on top?
Pressure cooking uses moist heat, so the tops will not brown in the way they would in an oven. Pale tops are expected and do not mean the muffins are raw. Check for set centers with a toothpick and, when needed, confirm that the center reaches the safe minimum temperature for an egg dish.

Can I bake this batter in the oven instead?
Yes. Divide it among six greased or lined wells in a standard muffin pan and bake at 375°F (190°C) until the tops are lightly golden and a toothpick comes out without wet batter, usually about 16 to 20 minutes. Oven times vary, so begin checking at 16 minutes. The oven version will have a browned top and a slightly drier, more familiar muffin texture.

Can I double the recipe?
You can double the batter, but do not crowd cups so tightly that steam cannot circulate, and do not fill them more than three-quarters full. Depending on the cooker and cup size, you may need to cook in two batches. Keep the pressure-cooking time the same for individual cups, and make sure the pot has the required water before each batch.

Can I use a different milk or oil?
Unsweetened oat or soy milk can replace dairy milk in the same amount; almond milk also works, though its flavor may come through slightly. Melted butter can replace the neutral oil for a richer taste, but let it cool until warm rather than hot before whisking it with the egg. Avoid reducing the liquid or fat without testing, since both help the small muffins stay tender.
