These muffins are the cozy crossover of a childhood favorite and a grown-up coffee-shop treat. They bake up tender, peanut-buttery, with a sweet jammy center and a buttery crumb topping that gives every bite a little crunch. No gimmicks — just straightforward steps and reliable results.
I test recipes until they behave, so what you’ll find here are practical notes: what to expect, where to save time, and how to avoid soggy centers. The steps below follow a single source of truth, so if you want to replicate exactly, follow the order and amounts as written.
Make a batch for a quick breakfast, an after-school snack, or a crowd-friendly brunch. They keep well for a few days at room temperature and travel nicely in a tin, which makes these muffins a useful addition to your regular baking rotation.
Ingredient Rundown
Ingredients
- 6 tablespoons unsalted butter — for richness in the batter; melts into the peanut butter for a smooth base.
- 3/4 cup peanut butter — the main flavor; use creamy for a uniform texture.
- 1 3/4 cups all-purpose flour — forms the structure of the muffins in the batter.
- 1 teaspoon baking soda — the leavening agent that gives lift.
- 1/4 teaspoon salt — balances sweetness and enhances flavor.
- 1/4 teaspoon cinnamon — a warm note that plays nicely with peanut butter and jam.
- 1 large egg — binds ingredients and adds tenderness.
- 1/2 cup packed brown sugar — adds moisture and a touch of caramel flavor to the batter.
- 2 teaspoons vanilla extract — rounds out the flavors and softens the peanut butter edge.
- 3/4 cup milk — thins the batter to the right consistency; whole milk gives the richest result.
- 12 ounces strawberry preserves — the jelly center; measure by weight for consistent distribution.
- 1/3 cup brown sugar — part of the crumb topping for chew and flavor.
- 1/3 cup sugar — part of the crumb topping for crunch.
- 1/4 teaspoon cinnamon — in the crumb topping for warmth.
- 1/4 teaspoon salt — enhances the crumb flavor and balances sweetness.
- 1/2 cup unsalted butter, melted — binds the crumb topping and helps it crisp.
- 1 1/2 cup all-purpose flour — the dry component of the crumb topping; creates the streusel texture.
Peanut Butter and Jelly Crumb Muffins, Made Easy
- Preheat the oven to 350°F. Line a muffin tin with paper liners or grease the cups.
- Make the crumb topping: in a medium bowl whisk together 1/3 cup brown sugar, 1/3 cup sugar, 1/4 teaspoon cinnamon and 1/4 teaspoon salt. Whisk in 1/2 cup melted unsalted butter until the sugar begins to dissolve (about 1–2 minutes). Stir in 1 1/2 cups all-purpose flour with a wooden spoon until the mixture forms dry, crumb-like pieces. Set the crumb topping aside.
- Melt the butter and peanut butter: place 6 tablespoons unsalted butter and 3/4 cup peanut butter in a microwave-safe bowl. Microwave 30 seconds, stir, then microwave in 15-second increments, stirring after each, until fully melted and smooth. Let cool slightly.
- Whisk the dry muffin ingredients: in a medium bowl combine 1 3/4 cups all-purpose flour, 1 teaspoon baking soda, 1/4 teaspoon salt and 1/4 teaspoon cinnamon. Set aside.
- In a large bowl whisk together 1 large egg, 1/2 cup packed brown sugar and 2 teaspoons vanilla extract until smooth.
- Stir the melted butter/peanut butter mixture into the egg mixture until combined and smooth.
- Add the dry ingredients to the wet mixture and stir until almost combined (the batter will be very thick). Pour in 3/4 cup milk and stir gently just until a cohesive batter forms; avoid overmixing.
- Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full (use an ice cream scoop or measuring cup for even portions).
- Divide the 12 ounces of strawberry preserves among the muffins, pressing the preserves into the center of each mound of batter so they sink toward the middle.
- Top each muffin generously with the prepared crumb topping, pressing the crumbs lightly onto the batter to adhere.
- Bake at 350°F for 18–22 minutes, until the tops are set and a toothpick inserted near (not through) the center comes out with only moist crumbs.
- Cool the muffins in the pan for 5–10 minutes. If you used liners, you can remove the muffins and finish cooling on a wire rack; if you did not use liners, let the muffins cool longer in the pan and remove gently with a spoon once they are firm enough to lift.
Why I Love This Recipe
There’s a lot to like: it captures that nostalgic PB&J flavor in a portable bite, but it’s not a flat cupcake. The peanut butter is front and center in the batter, the preserves add a clean, fruity pop in the middle, and the crumb topping gives texture that makes the muffins feel special. It hits sweet, salty, and buttery notes in one go.
It’s forgiving, too. The batter is thick, so small timing differences won’t ruin the structure. The crumb topping is straightforward and can be prepared while the oven heats. And because the jam gets nestled into the batter, you get a soft, jammy center without the fillings bubbling over and making a mess.
Budget & Availability Swaps
You don’t need boutique ingredients for these to shine. Here are practical swaps if you’re shopping on a budget or have limited pantry space:
- Peanut butter — Use any creamy peanut butter you have. Natural peanut butter works; it may separate when melted, so stir well. A store-brand jar will perform fine.
- Strawberry preserves — Any jam or preserves are acceptable. Seedless preserves or a slightly thicker jam will stay neater in the center. If you only have jelly, use it; the texture will be smoother but still delicious.
- Milk — Any milk works: whole, 2%, or a richer non-dairy like oat milk for a slightly different flavor. The batter just needs a liquid to come together.
- Unsalted butter — If you only have salted butter, reduce any additional salt you add elsewhere; this recipe uses small salt amounts, so the difference will be minor.
- Brown and white sugar — If you’re short on brown sugar, you can mix molasses with white sugar (1 tablespoon molasses per 1/2 cup sugar) as a last resort. Not necessary, but it’s an option.
Gear Checklist
- Muffin tin (12-cup) — for even baking.
- Paper liners or a pastry brush for greasing — liners make removal easier.
- Mixing bowls — at least two: one for dry, one for wet, and a medium bowl for the crumb.
- Wooden spoon or sturdy spatula — to fold the crumb and batter without overworking.
- Measuring cups and spoons — accuracy matters for baking.
- Ice cream scoop or measuring cup — for even batter portions.
- Wire rack — to finish cooling without soggy bottoms.
Slip-Ups to Skip
Nothing derails these muffins faster than overmixing or mis-placing the jam. Here are the common mistakes I see and how to avoid them.
- Overmixing the batter: Once you add the milk and fold to bring the batter together, stop stirring. Overmixing develops gluten and yields dense muffins. Aim for a thick, slightly lumpy batter.
- Dropping the jam on top: If you simply plop jam on top of a flat muffin surface it can spread and leak. Press the preserves into the center of the mound of batter so they sink slightly — that keeps the jam contained and creates a nice pocket.
- Putting on too much crumb: The topping is generous in this recipe, but pressing it lightly to adhere is enough. If the crumbs completely cover and press deep, they can impede rising; leave some crumbs loose for a crisp finish.
- Baking at the wrong temperature: The recipe calls for 350°F. If your oven runs hot, reduce by 10–15°F or check early. Undercooked centers are usually a timing or temperature issue.
- Removing muffins too soon: They need a short rest in the pan to firm up. Lift them too early and they may crumble or stick if you didn’t use liners.
Make It Your Way
This recipe is a template. Keep the structure and proportions but switch small elements to suit your taste.
Flavor and texture swaps
- Nut butter options: Almond or cashew butter can replace peanut butter if you prefer. Choose creamy varieties for an even batter.
- Jam variations: Raspberry, blueberry, apricot — any preserves will work. A thicker preserve will give a more distinct pocket; runnier jelly will meld into the batter more.
- Extra mix-ins: Stir in up to 1/2 cup chopped peanuts for crunch, or sprinkle coarse sugar on the crumb for extra sparkle.
- Less sweet: Reduce the crumb sugar by 1–2 tablespoons if you want a less sweet topping — the preserves will still give sweetness in the center.
Insider Tips
Small steps that make a big difference:
- Even portions: Use an ice-cream scoop to portion batter. It keeps baking times uniform and prevents some muffins from overbaking while others remain underdone.
- Jam distribution: Weigh the preserves if you want perfect equality — 12 ounces divided by 12 muffins is about 1 ounce per muffin (roughly 2 tablespoons).
- Crumb texture: The crumb should form dry, irregular pieces. If it’s too wet, add a tablespoon of flour; if it’s powdery, gently press it together — it’ll crisp in the oven.
- Check doneness near the filling: Insert a toothpick near (not through) the jam center. It should come out with moist crumbs, but not raw batter.
- Cooling strategy: Let muffins rest in the pan briefly, then move to a wire rack. This prevents soggy bottoms from trapped steam.
Freezer-Friendly Notes
These muffins freeze well if you plan ahead. Cool completely, then wrap individually in plastic wrap or place in a single layer in a freezer-safe container separated by parchment. Freeze up to 3 months.
To thaw, leave at room temperature for a couple of hours or microwave wrapped muffins for 20–30 seconds to warm through. If you like the crumb crisped, toast gently in a 325°F oven for 5–7 minutes after thawing.
FAQ
Q: Can I use crunchy peanut butter?
A: Yes. Crunchy will add texture in the batter and change the mouthfeel slightly. Melt and stir as directed; nuts in the butter can settle but won’t affect baking.
Q: What if my preserves are too runny?
A: If preserves are very runny, chill them briefly to firm up, or spoon and press a smaller amount into each muffin so it doesn’t sink too far and create a soggy cavity.
Q: How do I prevent the jam from sinking to the bottom?
A: Press preserves into the center of the batter mound rather than placing it on top of a flatter surface. The surrounding batter supports the preserves as the muffins rise.
Q: Can I make the crumb topping ahead?
A: Yes. Make the crumb up to a day ahead and refrigerate in an airtight container. If it firms in the fridge, break it into pieces with your fingers before using.
Q: Can I halve the recipe?
A: Yes. The recipe scales down cleanly. Use a smaller muffin tin or reduce baking time slightly; check at the earlier end of the baking window.
Hungry for More?
If you like these, try swapping the preserves for lemon curd and adding poppy seeds to the batter for a bright, tangy twist. Or turn the same idea into a coffee cake by using the crumb topping and skipping the jam, folding in chocolate chips or fresh berries instead.
Make a batch, share a couple with neighbors, and keep the rest for breakfast. These muffins are a small, dependable pleasure — and they reward the simple effort of baking at home.
