Easy Crochet Birthday Cake Bag Pattern: A Colorful Beginner-Friendly Project

Are you looking for your next fun, vibrant crochet project? If you love bright colors and adorable accessories, you are going to fall in love with this Crochet Birthday Cake Bag! Designed to look like a delicious, multi-layered treat, this bag is perfect for carrying your small essentials, phone, or even some actual treats to a party. The best part? It uses the beautiful gradients found in “cake” style yarns to create effortless stripes without you having to constantly switch colors manually.

This project is classified as an “easy” skill level, making it a fantastic choice for beginner crocheters who want to practice color changes, working in the back loops (often called “working in bumps”), and basic assembly. Whether you want a warm, autumnal look or a bright, summery vibe, there is a color palette here for everyone!

Materials & Abbreviations

Before you pick up your hook, let’s make sure you have everything you need to create this sweet little bag.

Yarn Requirements

To get that beautiful striped effect, you will need one ball of medium-weight (Category 4) cake yarn. Each cake typically contains five distinct shades. For this pattern, we have outlined three different color versions so you can customize your bag’s personality:

  • Version 1 (Toasted Meringue): A warm, neutral palette featuring Caramel (A), Brown (B), Cream (C), Cork (D), and Tan (E).
  • Version 2 (Sunset Macarons): A vibrant, warm palette featuring Red (A), Peach (B), Pink (C), Coral (D), and Navy (E).
  • Version 3 (Macarons): A bright, pastel palette featuring Light Pink (A), Dark Pink (B), Light Teal (C), Mint (D), and Dark Teal (E).

Note: When using cake yarn, gently push the colors from the center of the cake to separate them. Mark each shade as A, B, C, D, and E based on the lists above so you don’t get confused during the pattern!

Tools & Gauge

  • Crochet Hook: Size U.S. H/8 (5 mm) or the size needed to obtain your gauge.
  • Yarn Needle: For sewing pieces together and embroidery.
  • Gauge: 13 single crochet (sc) and 14 rows = 4 inches.
  • Finished Size: The bag will be approximately 8.25 inches wide and 5.75 inches tall (not including the strap).

Step-by-Step Instructions

Preparation Tips

To ensure your stripes look clean, remember to change colors by working the last 2 loops of the final stitch of the previous color with the new color. When you start a new row with a different color, remember that a Ch 3 at the beginning of a row counts as a double crochet (dc).

The Front and Back Panels

Make two: one for the front and one for the back.

Start with Color A. Chain 29. We will be working in the “bumps” at the back of the chain (the back loop) to create a textured foundation.

  1. 1st Row (RS): Working in the bumps at the back of the chain, 1 sc in the 2nd ch from the hook and 1 sc in each ch to the end. Turn. (28 sc).
  2. 2nd to 4th Rows: Ch 1. 1 sc in each st to the end of the row. Turn. At the end of the 4th row, join Color B and break Color A.
  3. 5th and 6th Rows: With Color B, ch 3. *1 dc in the next st, 1 sc in the next st. Repeat from * to the end of the row. Turn. At the end of the 6th row, join Color A and break Color B.
  4. 7th to 10th Rows: With Color A, ch 1. 1 sc in each st to the end of the row. Turn. At the end of the 10th row, join Color B and break Color A.
  5. 11th to 16th Rows: Repeat rows 5 through 10 once more. At the end of the 16th row, join Color C and break Color A.
  6. 17th Row: With Color C, ch 1. Working in front loops only, sl st in each st to the end of the row loosely. Turn.
  7. 18th Row: Working in the top loop of the slip stitches, ch 1. 1 sc in each st to the end of the row. Turn.
  8. 19th Row: Ch 1. 1 sc in each st to the end of the row. Fasten off.

The Side Panels

Note: Separate Color C into two small balls to be used for the different sections. Do not break a color while it is in use; instead, drop it to the wrong side (WS) to be picked up later.

Start with Color C, ch 16. With Color A, ch 28. With Color C, ch 17.

  1. 1st Row (RS): Working in the bumps at the back of the chain, 1 sc in the 2nd ch from the hook and 1 sc in each of the next 15 ch. With Color A, 1 sc in each of the next 28 ch, joining Color C in the last sc. With Color C, 1 sc in each ch to the end of the chain. Turn. (60 sc).
  2. 2nd to 6th Rows: Ch 1. 1 sc in each of the first 16 sc. With Color A, 1 sc in each of the next 28 sc. With Color C, 1 sc in each sc to the end of the row. Turn. Fasten off.

The Top Flaps

Make two.

Start with Color C, ch 29. Working in the bumps at the back of the chain, 1 sc in the 2nd ch from the hook and 1 sc in each ch to the end. Turn. (28 sc).

  1. 2nd and 3rd Rows: Ch 1. 1 sc in each sc to the end of the row. Turn. Fasten off.

The Strap

Start with Color E, ch 73.

  1. 1st Row: Working in the bumps at the back of the chain, 1 sc in the 2nd ch from the hook and 1 sc in each ch to the end. Turn. (72 sc).
  2. 2nd Row: Ch 1. 1 sc in each sc to the end of the row. Fasten off.

Finishing

Assembling the Bag

This is where your hard work comes together! To assemble, we will join the Front, Sides, and Back pieces.

  1. Align the pieces: With the Right Side (RS) facing out, align the Front and Sides so that the “A” section of the Sides is along the foundation chain of the Front, and the “C” section of the Sides is along the ends of the rows.
  2. Join the edges: Working through both thicknesses, join Color C with a sl st at the top right corner of the Front. Ch 1.
  3. Work the perimeter: Working from left to right (instead of the usual right to left), work 1 reverse sc in each st across the Front. When you reach the ends of the rows of the first Top piece and Sides, work 3 reverse sc.
  4. Connect the second side: Align the second Top piece with the Back as you did the first. Working around the ends of the rows of the second Top piece and Sides, work 3 reverse sc.
  5. Complete the Back: Work 1 reverse sc in each st across the Back. Working around the ends of the rows of the second Top piece and Sides, work 3 reverse sc. Join with a sl st to the first st. Fasten off.

Creating the Closure

The closure gives the bag its “button” look. With the RS facing, join Color D with a sl st to the 14th st of the first Top piece.

  1. Ch 3.
  2. Yarn over and draw up a long loop (equal in height to your starting ch 3).
  3. Yarn over and draw through 2 loops on the hook.
  4. Repeat this process 6 times all in the same space as your slip stitch.
  5. Yarn over and draw through all 6 loops on the hook.
  6. Yarn over and draw through the last 2 loops on the hook.
  7. Ch 3. Sl st in the next sc. Fasten off.

For the second Top piece, repeat the process but instead of a loop, Ch 8 and sl st in the next sc.

Decoration and Embroidery

To give your bag that extra “birthday cake” magic, add some sprinkles!

  • Sprinkles: Using a yarn needle and Colors B, D, and E, embroider small “sprinkles” onto the Top flaps and the section of the Sides worked in Color C. Use a straight stitch (spoke stitch) and French knots for a professional look.
  • Icing Detail: Using Color D, work surface slip stitch arches over the last 2 rows of the Front and Back to mimic icing drips.
  • Attach the Strap: Using a yarn needle and Color E, sew each end of the strap to the Sides, approximately 1 inch down from the top edge.

Tips for Success

  • Mastering the “Bumps”: Working in the bumps (the back loop of the chain) is what gives this bag its wonderful texture. If your edges look a bit uneven at first, don’t worry—it will even out as you continue!
  • Tension is Key: When making the closure loop, ensure your loops are tall enough to fit over the button, but not so loose that they look sloppy.
  • Color Management: Since this pattern relies heavily on specific color sequences (A, B, C, D, E), keep a small piece of paper next to you to check off which color you should be using for each row.
  • Reverse Sc: The reverse single crochet is used during assembly to create a very sturdy, clean join that won’t gap easily.
